• Effects on cognitive function and mood state due to interventions involving finger movements in healthy older adults

  Atsuko Hayashi, Momoka Ijima, Keitaro Ito, Sinan Chen, Masahide Nakamura

  Abstract Previous studies have reported relationships between hand dexterity and cognitive functions. However, there are few studies examining effects of finger exercise interventions on cognitive functions. Here we administered working memory(WM) tasks involving finger movements as interventions in healthy older subjects and investigated changes in cognitive functions and mood state due to the interventions. The participants were 71 healthy older people in total (a cross-over study). They were randomly assigned to the following three intervention groups; Group A performed a WM task using numbers and Japanese kana characters accompanied by finger movements; Group B performed finger movements in accordance with the presented numbers or kana; Group C were allocated to the WM task without finger movements. Cognitive functions [Trail Making Test(TMT)-A/B, Digit/Tapping Span] and mood states (the Two-Dimension Mood Scale) were evaluated. In the comparison of before and after the intervention, group A significantly improved the time required for TMT-A/B. Group B showed a significant decrease in the time required for TMT-B. In group C, the score of Digit Span was increased and all groups showed increased arousal level and decreased mood stability significantly. In between-group comparisons, no significant changes were observed in all evaluations. These results suggest that the interventions involving finger movements may improve cognitive functions such as attention and executive functions and working memory in healthy older people. The intervention tasks might affect in mood states regardless of finger exercises. In conclusion, it is suggested that finger exercises may be used as intervention tools to improve cognitive functions.

• Towards Sensor-Based Mobility Assessment for Older Adults: A Multimodal Framework Integrating PoseNet Gait Dynamics and InBody Composition

  Sinan Chen, Lingqi Kong, Zhaozhen Tong, Yuko Yamaguchi, Masahide Nakamura

  The acceleration of global population aging has driven a surge in demand for health monitoring among older adults. However, traditional mobility assessment methods mostly rely on invasive measurements or laboratory-grade equipment, making it difficult to achieve continuous monitoring in daily scenarios. This study investigated the correlation between dynamic gait characteristics and static body metrics to enhance the understanding of elderly mobility and overall health. A sensor-based framework was implemented, which utilizes the Short Physical Performance Battery (SPPB), combined with PoseNet (a vision-based sensor) for dynamic gait analysis, and the InBody bioelectrical impedance device for static body composition assessment. Key variables comprised the dynamic metric mean directional shift and static metrics, including skeletal muscle index (SMI), skeletal muscle mass (SMM), body fat percentage (PBF), visceral fat area (VFA), and intracellular water. Nineteen elderly participants aged 60–89 years underwent assessments; among them, 16 were males (84.21%), and 3 were females (15.79%), 50% were in the 80–89 age group, 95% did not live alone, and 90% were married. Dynamic gait data were analyzed for center displacement and horizontal directional shifts. A Pearson correlation analysis revealed that the mean directional shift positively correlated with SMI (ρ=0.561, p<0.01), SMM (ρ=0.496, p<0.01), and intracellular water (ρ=0.497, p<0.01), highlighting the role of muscle strength in movement adaptability. Conversely, negative correlations were found with PBF (ρ=−0.256) and VFA (ρ=−0.342, p<0.05), suggesting that greater fat mass impedes dynamic mobility. This multimodal integration of dynamic movement patterns and static physiological metrics may enhance health monitoring comprehensiveness, particularly for early sarcopenia risk detection. The findings demonstrate the framework’s potential, indicating mean directional shift as a valuable dynamic health indicator.

• Enhancing Personalized Service Development with Virtual Agents and Upcycling Techniques

  Takuya Nakata, Sinan Chen, Sachio Saiki, Masahide Nakamura

  Abstract In this study, aimed at achieving Society 5.0, we explore efficient development methods for services tailored to individual user needs. The diversification of user demographics has led to swiftly changing service demands, increasing the necessity for personalized adaptation. However, developing services tailored to individual users requires specialized knowledge and incurs high costs. This research focuses on developing technologies that enable service development through a concrete understanding of user needs. Utilizing an interactive needs extraction system with a virtual agent (VA) developed in prior studies, along with the Sharing Upcycling Cases with Context and Evaluation for Efficient Software Development (SUCCEED) system, we aim to automate the extraction of user needs and provide developers with relevant insights. Prior research has found it challenging to grasp the outline of services to be developed from user statements. However, a new method using large language models (LLM) has enabled the automatic extraction of novel service needs. Experiments have shown the potential to automatically provide development insights for 67% of ideal needs.

• Needs Companion: A Novel Approach to Continuous User Needs Sensing Using Virtual Agents and Large Language Models

  Takuya Nakata, Masahide Nakamura, Sinan Chen, Sachio Saiki

  In today’s world, services are essential in daily life, and identifying each person’s unique needs is key to creating a human-centered society. Traditional research has used machine learning to recommend services based on user behavior logs without directly detecting individual needs. This study introduces a system called Needs Companion, which automatically detects individual service needs, laying the groundwork for accurate needs sensing. The system defines a needs data model based on the 6W1H framework, uses virtual agents for needs elicitation, and applies large language models (LLMs) to analyze and automatically extract needs. Experiments showed that the system could detect needs accurately and quickly. This research provides interpretable data for personalized services and contributes to fields like machine learning, human-centered design, and requirements engineering.

• SUCCEED: Sharing Upcycling Cases with Context and Evaluation for Efficient Software Development

  Takuya Nakata, Sinan Chen, Sachio Saiki, Masahide Nakamura

  Software upcycling, a form of software reuse, is a concept that efficiently generates novel, innovative, and value-added development projects by utilizing knowledge extracted from past projects. However, how to integrate the materials derived from these projects for upcycling remains uncertain. This study defines a systematic model for upcycling cases and develops the Sharing Upcycling Cases with Context and Evaluation for Efficient Software Development (SUCCEED) system to support the implementation of new upcycling initiatives by effectively sharing cases within the organization. To ascertain the efficacy of upcycling within our proposed model and system, we formulated three research questions and conducted two distinct experiments. Through surveys, we identified motivations and characteristics of shared upcycling-relevant development cases. Development tasks were divided into groups, those that employed the SUCCEED system and those that did not, in order to discern the enhancements brought about by upcycling. As a result of this research, we accomplished a comprehensive structuring of both technical and experiential knowledge beneficial for development, a feat previously unrealizable through conventional software reuse, and successfully realized reuse in a proactive and closed environment through construction of the wisdom of crowds for upcycling cases. Consequently, it becomes possible to systematically perform software upcycling by leveraging knowledge from existing projects for streamlining of software development.

• Consecutive and Effective Facial Masking Using Image-Based Bone Sensing for Remote Medicine Education

  Sinan Chen, Masahide Nakamura, Kenji Sekiguchi

  Unlike masking human faces from images, facial masking in real-time, frame by frame from a video stream, presents technical challenges related to various factors such as camera-to-human distance, head direction, and mosaic schemes. In many existing studies, expensive equipment and huge computational resources are strongly required, and it is not easy to effectively realize real-time facial masking with a simpler approach. This study aims to develop a secure streaming system to support remote medicine education and to quantitatively evaluate consecutive and effective facial masking using image-based bone sensing. Our key idea is to use the facial feature of bone sensing instead of general face recognition techniques to perform facial masking from the video stream. We use a general-purpose computer and a USB fixed-point camera to implement the eye line mosaic and face mosaic. We quantitatively evaluate the results of facial masking at different distances and human head orientations using bone sensing technology and a depth camera. we compare the results of a similar approach for face recognition with those of bone sensing. As the main results, consecutive face masking using bone sensing is unaffected by distance and head orientation, and the variation width of the mosaic area is stable within around 30% of the target area. However, about three-fourths of the results using conventional face recognition were unable to mask their faces consecutively.

• Assisting Personalized Healthcare of Elderly People: Developing a Rule-Based Virtual Caregiver System Using Mobile Chatbot

  Chisaki Miura, Sinan Chen, Sachio Saiki, Masahide Nakamura, Kiyoshi Yasuda

  To assist personalized healthcare of elderly people, our interest is to develop a virtual caregiver system that retrieves the expression of mental and physical health states through human–computer interaction in the form of dialogue. The purpose of this paper is to implement and evaluate a virtual caregiver system using mobile chatbot. Unlike the conventional health monitoring approach, our key idea is to integrate a rule-based virtual caregiver system (called “Mind Monitoring” service) with the physical, mental, and social questionnaires into the mobile chat application. The elderly person receives one question from the mobile chatbot per day, and answers it by pushing the optional button or using a speech recognition technique. Furthermore, a novel method is implemented to quantify the answers, generate visual graphs, and send the corresponding summaries or advice to the specific elder. In the experimental evaluation, we applied it to eight elderly subjects and 19 younger subjects within 14 months. As main results, its effects were significantly improved by the proposed method, including the above 80% in the response rate, the accurate reflection of their real lives from the responses, and high usefulness of the feedback messages with software quality requirements and evaluation. We also conducted interviews with subjects for health analysis and improvement.

• Uni-Messe: Unified Rule-Based Message Delivery Service for Efficient Context-Aware Service Integration

  Takuya Nakata, Sinan Chen, Masahide Nakamura

  Rule-based systems, which are the typical technology used to realize context-aware services, have been independently implemented in various smart services. The challenges of these systems are the versatility of action, looseness, and the coding that is needed to describe the conditional branches. The purpose of this study was to support the realization of service coordination and smart services using context-aware technology by converting rule-based systems into services. In the proposed method, we designed and implemented the architecture of a new service: Unified Rule-Based Message Delivery Service (Uni-messe), which is an application-neutral rule management and evaluation service for rule-based systems. The core part of the Uni-messe proposal is the combination of a Pub/Sub and a rule-based system, and the proposal of a new event–condition–route (ECR) rule-based system. We applied Uni-messe to an audio information presentation system (ALPS) and indoor location sensing technology to construct concrete smart services, and then compared and evaluated the implementation to “if this then that” (IFTTT), which is a typical service coordination technology. Moreover, we analyzed the characteristics of other rule-based systems that have been serviced in previous studies and compared them to Uni-messe. This study shows that Uni-messe can provide services that simultaneously combine versatility, ease of conditional description, looseness, context independence, and user interface (UI), which cannot be achieved using conventional rule-based system services. By using Uni-messe, advanced heterogeneous distributed service coordination using rule-based systems and the construction of context-aware services can be performed easily.

• Exploiting Motivation Subscales for Gamification of Lifelogging Application

  Aoi Nagatani, Sinan Chen, Masahide Nakamura, Sachio Saiki

  Continuous data input is essential for lifelogging services, where users input their daily records. But whether the user can continuously input data depends mainly on the user's motivation. This article presents a new method of introducing gamification in line with the purpose of lifelogging. The authors introduce a comprehensive set of gamification features based on motivation subscales into a lifelogging service. Meanwhile, the authors elucidate which gamification features correspond to which motivation subscales are effective for lifelogging, including intrinsic motivation, introjected regulation, integrated regulation, identified regulation, and external regulation. As a case study, the authors introduce the five gamification features corresponding to each motivation subscale into work support service (WSS) designed to record and review work hours. The authors also compare and evaluate changes in user behavior before and after the introduction of the gamification features. In this way, user motivation for continuous input increases when gamification in the WSS is confirmed.

• Toward a New Debugging Paradigm to Overcome Complexity of Program Executions

  Izuru, Kume, Naoya, Nitta, Masahide, Nakamura

  デバッグはソフトウェア開発の他の工程，特にプログラミングと対照的にその作業効率は根本的に改善されないまま多くの労力と時間が費され，開発全体の律速段階を形成する状況が何十年も続いている．現在の一般的なデバッグ方式ではブレイクポイントの設定とプログラムの再実行，ステップ実行とスタック情報の調査を繰り返すことによってデバッグ，特に不具合箇所とその実行の時機を特定する診断が形成される．実用的なプログラムの実行は一般にきわめて複雑である．従来のデバッグ方式で診断を形成しようとすると，この複雑性が作業量に直接反映されてしまうため，結果として作業に費される労力と時間が爆発的に増大してしまう．これまでに提案されてきた様々な支援手法もこうした従来のデバッグ方式を前提とする限りその真価を発揮して産業界に広く受け入れられることは困難であると思われる．本発表で我々は複雑性を克服して診断を形成するための新しいデバッグの枠組である，関心指向デバッギングを提案する．関心指向デバッギングは診断者が作業の過程で関心を有した断片的な情報である関心に基づいてプログラム実行を抽象化し，オブジェクト指向プログラム特有の非局在化を復元する行為によって従来方式の行為を置き換える．本発表では実際に実施された診断事例の分析を通じて関心指向デバッギングの有効性を検証する． Debugging has been a time-consuming process and the bottleneck of software development for decades, although other development processes, especially programming, show great improvement in their efficiency. Currently for making a diagnosis, which explains the chain of infection to a failure, there is a widespread debugging style that consists of repeated actions of setting breakpoints, restarting a program, step executions, and inspection of stack data. In general, an execution of a practical program is very complex, and its complexity directly requires a large number of actions, and thus a large amount of time and effort for a diagnosing task. Existing supporting methods can't show their potential performance if they are combined with these debugging actions, which is one of the reasons practitioners are not always positive about these proposed methods, we believe. In this presentation, we propose Concern-Oriented Debugging, which is a new debugging paradigm that aims at overcoming the complexity of program executions in diagnosing tasks. Concern-Oriented Debugging replaces existing debug actions with those that make an abstraction of a program execution and recover delocalization of the object-oriented program design. We show the effectiveness of this new debugging paradigm by a diagnosing task of a real debugging example.

  In PBL, it is often pointed out that it is difficult to qualitatively evaluate the improvement of students' fundamental competencies for working persons. In this study, we propose a method to evaluate students' growth and to improve classes through self-evaluation by students and objective evaluation by a third party as an approach to qualitative evaluation of PBL courses. In the proposed method, we aim to evaluate the validity of the subjective self-evaluation by the students before and after taking the PBL course, based on the objective evaluation. In this paper, we report on the evaluation results of the PBL course in 2017 and 2018 by the proposed method using the self-evaluation of fundamental competencies for working persons before and after taking the PBL course and the objective evaluation through PROG competency test.

  AiBiC Kansai offers an education course, AiBiC Spiral, designed to develop abilities to solve individual social issues using Big Data, artificial intelligence, and Cloud technologies through teamwork. In this paper, we report on the problems of the environments for the education program and the discrepancies in the expectations on topics and contents found by the analysis of the questionnaire conducted in 2017, and describe the activities and results performed to improve the program in 2018. Through the improvements, we have found that the problem on the program environments has been dissolved. However, as for the discrepancies in the expectations, we have revealed that only some part of the problem was improved and there were still some students found the topics and contents provided by the program were different from their expectations.

• オブジェクト指向プログラム固有なデバッグの困難性を克服する Back-in-Time デバッガの実現に向けて

  久米出, 波多野賢治, 中村匡秀, 柴山悦哉

  逆回し (back-in-time) デバッガはプログラムのトレース (実行履歴) を記録して過去の状態の参照を可能する機能を有しており，デバッグに於ける診断のあり方を根本から変える可能性を秘めている．しかしながらその機能を有効に活用するためには，作業者が膨大なトレースの中から適切な実行時点を指定し，その状態の正不正を判定しなければならない．こうした指定や判定は作業者自身のプログラム理解に大きく依存している．オブジェクト指向プログラミングはプログラムの再利用性や拡張性が向上させる反面，コードの理解を困難にする傾向が指摘されている．我々はこうしたオブジェクト指向プログラムに固有な問題を解決するために，外挿診断法 (diagnosis by extrapolation) という手法を提案し，それを実現する逆回しデバッガを開発中である．本手法は指定された時点の実行文脈を，作業者の既知の情報を用いて抽象化する事によって，問題解決を実現する点に最大の特徴を有している．本論文では実用的なプログラムのデバッグ事例を通じて逆回しデバッガが実装すべき機能と手法の有効性の評価方法を考察する．

• 家庭における省エネ促進のための電力消費振り返りサービスの実装と評価

  Hiroshi IGAKI, Hideharu SETO, Masayuki FUKUDA, Shinsuke MATSUMOTO, Masahide NAKAMURA

  近年,住宅設備の電化や家電機器の増加・性能向上を要因として,家庭における消費電力量増加が重要課題となっている.家庭内の省エネ実現を目的として,ネットワークに接続された電力センサ等を用いた宅内の消費電力量可視化するサービスが研究・開発されている.実際に消費電力量の可視化によってユーザの省エネ行動を促進することができるという実験結果も現れつつある.一方で,既存サービスのほとんどは宅内の消費電力量のログを可視化するものであり,ユーザの在/不在や室温,照度といった環境状態に基づいた電力の消費結果と消費の原因の因果関係を後から細かく振り返ることを目的としていない.本研究では,HNSにおいて取得可能な様々なログを組み合わせることで,ユーザが日々の電力消費をより細かく振り返ることができる「電力消費振り返りサービス」を提案する.また,提案サービスを実際のホームネットワークシステム上で実装し,有用性を確認するための評価実験を行った.実験により,提案サービスを用いて「電力消費超過」,「サービス提供不能」,「環境状態無視」といった分類でのユーザの電力浪費行動全てを具体的な根拠に基づいて発見することができた.

  様々なサービスを通じて記録された各種ライフログを,ネットワーク越しに統合・集約することで,より高い付加価値をもつサービスへ発展させることが可能である.本論文では,異種ライフログ統合のための標準データモデル(LLCDM),及び標準データモデルにアクセスするためのマッシュアップAPI(LLAPI)を提案する.各種ライフログの記録項目を5W1Hの観点から分類,整理することで,ライフログの種類に強く依存しない中立的なデータモデルを構築する.整理された標準データに対し,汎用的なマッシュアップAPIを設けることで,効率的かつ柔軟なライフログの統合を支援する.LLCDMとLLAPIの有効性を確かめる評価実験として,二つのライフログを統合するアプリケーションを題材とした開発実験を行う.

• 時空間情報と動作に基づく認証方法

  Masateru Tsunoda, Kyohei Fushida, Yasutaka Kamei, Masahide Nakamura, Kohei Mitsui, Keita Gotoh, Kenichi Matsumoto

  We propose a new authentication method based on actions and spatiotemporal information such as location, elapsed time, and travel distance of a user. To be authenticated, a user performs certain actions at certain points defined with spatiotemporal information. To apply spatiotemporal information to authentication, it is needed that suppressing probability of authentication failure of regular user, for it is not easy to retry authentication. So we propose partial matching authentication which allows partial mistake of user's authentication procedure. Also, we define combination of spatiotemporal information and action as spatiotemporal character, and formalize security evaluation of our method based on it. In addition, we show security effectiveness of our method with an experiment. The experiment showed that false rejection rate of our method is 0.233% and false acceptance rate is 0.010%.

• APIライブラリ名隠ぺいのための動的名前解決を用いた名前難読化

  Haruaki Tamada, Masahide Nakamura, Akito Monden, Ken-ichi Matsumoto

  名前難読化とは,プログラム中の名前(識別子)を別の名前に付け替えることで,プログラムを理解しづらいものにするソフトウェア保護手法である.従来の名前難読化手法は,各名前を静的に別の文字列で置換するものであり,プログラム中に現れる任意のユーザ定義の名前を隠ぺいできる.しかしながら,従来手法を用いてシステム定義の名前(標準ライブラリやAPIの呼出し等)を難読化することは,プログラムの移植性を著しく低下させるため,現実的に不可能である.そこで本論文では,オブジェクト指向言語を対象に,システム定義の名前をも隠ぺい可能な新たな名前難読化手法を提案する.具体的には,プログラム中の名前使用部分をあらかじめ暗号化しておき,実行時に名前を復号して当該処理を実行する,動的名前解決の仕組みを導入する.提案手法では,オブジェクト指向言語のリフレクション機構を用いて,クラスの参照,メソッド呼出し,フィールドの参照・代入に現れる任意の名前を動的解決する方法を実現している.また,提案手法をJavaプログラム用に実装し評価実験を行った.ある実用プログラムへの適用では,4.11倍の性能劣化でプログラム中のすべてのクラス名,メソッド名,フィールド名(計10,580回出現)を難読化できることが分かった.

• Quantitative Analysis of Information Leakage in Security-Sensitive Software Processes

  Kanzaki Yuichiro, Igaki Hiroshi, Nakamura Masahide, Monden Akito, Matsumoto Ken-ichi

  This paper presents a method to evaluate the risk of information leakage in software processes for security-sensitive applications. A software process is modeled as a series of sub-processes, each of which produces new work products from input products. Since a process is conducted usually by multiple developers, knowledge of work products is shared among the developers. Through the collaboration, a developer may share with others the knowledge of products that are not related to the process. We capture the transfer of such irrelevant product knowledge as information leakage in a software process. In this paper, we first formulate the problem of information leakage by introducing a formal software process model. Then, we propose a method to derive the probability that each developer d knows each work product p at a given process of software development. The probability reflects the possibility that someone leaked the knowledge of p to d. We also conduct three case studies to show the applicability of leakage to practical settings. In the case studies, we evaluate how the risk of information leakage is influenced by the collaboration among developers, the optimal developer assignment and the structure of the software process. As a result, we show that the proposed method provides a simple yet powerful means to perform quantitative analysis on information leakage in a security-sensitive software process.

• Use Case Maps を用いたサービス競合可能シナリオの導出と実験的評価

  Pattara Leelaprute, Masahide Nakamura, Ken-ichi Matsumoto, Tohru Kikuno

  サービス競合(Feature Interactions)とは, 複数の通信サービスを組み合わせたとき, 単独サービスで予期しない動作が発生する不具合を指す.すべてのサービス競合を厳密に検出し, 解消することは, サービス数及びシナリオ数の組合せ爆発により, 非常に困難な問題として知られている.そこで, 本研究では電話通信サービスを対象として, サービス開発の要求段階において, 「競合が起こりがちな」シナリオを低コストで導出するための枠組みを提案する.具体的には, Use Case Maps (UCMs)と呼ばれる要求記述法のスタブプラグインという概念を利用し, 基本電話サービスと付加サービスのシナリオを記述する.その後, UCMs上の三つのパス条件により, サービス競合が発生する可能性の高いシナリオを導出する.UCMsのシンプルなパス解析により, 競合の可能性があるシナリオを大幅に絞り込むことができる.また, 実際の携帯電話サービスに提案法を適用して評価実験を行った.2560の全サービスシナリオに対して, 提案法の適用により競合可能シナリオを148にまで絞り込むことができた.検証の結果, 導出された競合可能シナリオには, 既知のサービス競合がすべて含まれることが分かった.更に, いくつかの新たなサービス競合を発見できた.

• Implementation of Appliance Controller Service in Cloud-Based Home Network Service

  Hikaru INOMOTO, Satoshi TAKATORI, Shinsuke MATSUMOTO, Sachio SAIKI, Masahide NAKAMURA

  Home network system (HNS) provides a variety of value-added services by orchestrating house-hold appliances and sensors. In our previous research, we have proposed Cloud HNS that delegates all of HNS functions to Cloud. In this paper, we propose IRaaS (Infrared as a Service) which controls legacy house-hold appliances based on infrared signal controlling, as a Cloud HNS service. IRaaS is consist of two components, IR Proxy and jRemocon. IR Proxy is a service that delegates control request to jRemocon, and jRemocon is a device that transmits infrared signal to execute appliance control. Using its components, IRaaS executes requested appliance control. Then, we design and consider elements required for implementing IRaaS, and we also create and test a prototype. Based on these results, we discuss the effectiveness of proposed system.

• Considering Architecture for Managing House Log in Cloud-Based Home Network System

  LEE Junho, TAKATORI Satoshi, SAIKI Sachio, MATSUMOTO Shinsuke, NAKAMURA Masahide

  We have been developing a novel home network system, called Cloud-HNS, which manages home servers and all the services within a cloud. The HNS services often use house log which is log data gathered from the environment and devices in a house. Since the house log contains security-privacy information, the house log must be managed carefully in cloud-HNS. In this paper, we propose a new architecture to manage the house log in the cloud-HNS. In the proposed architecture, for every house, a dedicated virtual home server manages the private log of the house. Also, a shared virtual city server is deployed to manage public de-identified data. The virtual home server provides home services for individual household, whereas the virtual city server provides smart city services using the data gathered from multiple houses within the city. In this paper, we also develop a prototype system that collects house log in the cloud, using a sensor box and Raspberry Pi.

• Considering Common Data Model for Indoor Location-aware Services

  NIU Long, MATSUMOTO Shinsuke, SAIKI Sachio, NAKAMURA Masahide

  Recently, research and development have been conducted on the Indoor Positioning System (IPS), which identifies locations of various indoor objects. The indoor location is promising to achieve sophisticated Indoor Location-Aware Services (InLAS), and some practical services come onto market. However, the conventional system does not supposed to reuse the data and program of the indoor locations of another system. This makes the system complex and difficult to manage. To cope with the problem, this paper presents Data Model for Indoor Location (DM4InL), which prescribes a common data model independent of implementation of IPS or the usage of InLAS. The proposed DM4InL represents the location of every indoor object in a standard way, by using three kinds of models: position, building and object models. The proposed method achieves loose-coupling of InLAS and IPS, which significantly improves the efficiency and reusability in the InLAS development.

• Developing Cloud Service for Controlling Home Appliances

  LEE Junho, TAKATORI Satoshi, SAIKI Sachio, MATSUMOTO Shinsuke, NAKAMURA Masahide

  The programmable remote control system is a convenient tool that can consolidate multiple controllers of various house-hold appliances. It is also adopted in the emerging home network systems. However, the control signals of appliances are registered and maintained within individual home, which imposes a heavy burden on a home user. To cope with the problem, this paper presents Remocon as a Service (RaaS), an appliance remote controller service using the cloud computing. The key idea is to manage and share all the control signals within the cloud, and provide the signals as service for various users and applications. By using the cloud, RaaS overcomes the problem of the signal registration and management. It also decouples the feature of remote control from user interface, which achieves a variety of remote control applications. In this paper, we focus on the conventional infrared remote control (IrDA), and discuss the architecture, primary databases, and user interface of RaaS. We also implement a prototype of a signal transmission module of RaaS using Raspberry Pi and LIRC, in order to see practical feasibility.

  MATSUMOTO Shinsuke, SAIKI Sachio, NAKAMURA Masahide

  In the current information technology society where the cloud services are generally spread, it is a societal and important challenge to promote cloud computing education. In this paper, we propose a framework of virtual load simulation which replicate the response time to conduct auto scalling exercise in cloud education curriculum. The proposed framework replicate the response time of cloud services by using thread waiting methods such as sleep command. This allows us to have experience of virtualized auto scalling situation without actual load to physical computing resources. In addition, we report expertise obtained in an actual auto scaling exercise which conducted as a part of ministry's educational program.

• Implementing Materialized View as a Service for Large-Scale House Log in Smart City

  ISE Yuki, YAMAMOTO Shintaro, MATSUMOTO Shinsuke, SAIKI Sachio, NAKAMURA Masahide

  We have proposed a logging platform, called Scallop4SC(Scalable Logging Platform for Smart City), for managing various and large-scale log data from smart houses within a smart city. Moreover, we design that Scallop4SC provides MVaaS(Materialized View as a Service), which supports processing and using house log efficiently. In this paper, we implement an architecture of MVaaS using MapReduce on Hadoop and HBase KVS. Concretely, MVaaS automatically generates MapReduce programs with a spec for processing log data. The spec are drawn based on retrieval conditions or processing method for house log. By treating MVaaS, a developer of an application can dynamically create and efficiently access smart city data by only describing data specification for the application.

• A Framework for Personal Sensor Box in Mobile Environmental Sensing

  OKUSHI Akihiro, MATSUMOTO Shinsuke, SAIKI Sachio, NAKAMURA Masahide

  The mobile environmental sensing, where mobile users measure surrounding information with hand-held sensors, is a powerful means of the participatory sensing. We are studying the personal sensor box, by which individual user performs personalized mobile sensing with favorite sensors. This paper presents an application framework for the personal sensor box that enhances the flexibility of the applications towards the variety of sensor configurations. The proposed framework consists of three layers: (1) ConcreteSensor Layer, wrapping sensor devices and implementing device-specific operations, (2) AbstractSensor Layer, abstracting the devices with common sensor operations, (3) SensorBox Layer, aggregating multiple sensors and providing measured data for various applications. The proposed framework allows a user to flexibly customize his sensor box, and to easily implement applications using the customized box. We develop a prototype of a personal sensor box with 9 kinds of Phidgets sensors.

• Implementing Execution Platform for Managing Context-Aware Services Based on Heterogeneous and Distributed Web Services

  Hiroki Takatsuka, Sachio Saiki, Shinsuke Matsumoto, Masahide Nakamura

  With the spread of Machine-to-Machine (M2M) and cloud services, we have become to be able to use heterogeneous and distributed data. Implementation of the service which judges the context and controls autonomous from these data is expected. We have previously proposed the framework, which can create and manage in a unified manner context-aware services using heterogeneous and distributed Web services (sensor services, information system, state of appliance services and so on). The proposed framework consists of five layers and we define the context based on the data of the existing Web services, and then define the context-aware service by the ECA rule that is a set of event, condition and action. In this paper, we implement a platform based on the framework. The platform has the functions to register, delete, get and edit elements in each layer and to run the services. We implement these using Java, and publish APIs as the Web service.

• Implementing Caching Mechanism to Improve Efficiency of Service-Oriented Mining Software Repository

  Yasutaka Sakamoto, Shinsuke Matsumoto, Masahide Nakamura

  We have proposed a framework called SO-MSR (Service-Oriented Mining Software Repository), which applied service-oriented architecture to MSR techniques. Following the SO-MSR, we have developed a web service, named MetricsWebAPI, for metrics calculation from a variety of software repositories and a variety source codes. One of the challenges of MetricsWebAPI is low usability in terms of response time for MSR processing requests. The goal of this paper is to improve service interaction for MSR services deployed in SO-MSR. In this paper, we apply a caching mechanism and asynchronous API to MSR services. In MSR processing, all of repository data are past logs and processed result can be reused to other MSR services if once MSR applied to the repository data. Asynchronous API realizes parallel and batch processing to MSR services. We have conducted a experimentalevaluation to confirm the efficiency of applying a caching mechanism to MSR services.

• Introducing Multiple Microphone Arrays for Enhancing Smart Home Voice Control

  Shimpei Soda, Masahide Nakamura, Shinsuke Matsumoto, Shintaro Izumi, Hiroshi Kawaguchi, Masahiko Yoshimoto

  We have previously developed a voice control system for a home network system (HNS), using a microphone array technology. Although the microphone array achieved a convenient hands-free controller, a single array had limitations on coverage of sound collection and speech recognition rate. In this paper, we try to overcome the limitations by increasing the number of the microphone arrays. Specifically, we construct a microphone array network using four separate arrays, and enhance algorithms of sound source localization (SSL) and sound source separation (SSS) on the network. We also conduct an experimental evaluation, where precision of SSL and speech recognition rate are evaluated in a real HNS test-bed. As a result, it is shown that the usage of multiple arrays significantly improves the coverage and speech recognition ratio, compared with the previous system.

• Considering HTable Table Design for Efficient Attribute Search

  NAKAMURA Masahide

  Our long-term goal is to establish a generic datastore and a service platform for bigdata where heterogeneous applications can share and use the bigdata horizontally. The emerging key-value store (KVS), including HBase, has been proven to be useful for managing the bigdata. However, design of a KVS-based datastore often depends heavily on the application how the data is used and searched. This significantly declines generality and extensibility of the datastore. In this paper, we present a design method of HBase tables that achieves generic data search by various attributes. The key idea is to construct an index table in which all permutations of attribute values are used as row keys, pointing to contents of a main data table. The index table allows efficient data retrieval by any attribute specified by applications. A case study using smart city log illustrates practical feasibility of the method.

• Implementing API of Large-scale House Log Data Platform in Smart City

  Shintaro YAMAMOTO, Shinsuke MATSUMOTO, Masahide NAKAMURA

  Smart city is a next-generation city planning. In the smart city, some value-added services are provided using wide variety of logs collected from various appliances and sensors. In our previous work, we have been proposed and developed a smart city platform, called Scallop4SC that supports collecting and processing the extremely large-scale log data. This system stores variety of logs on key-value store, and supports the statistical processing of the logs on Hadoop. And we designed a meta-data scheme for smart city configuration information, designed Scallop4SCAPIs for accessing stored logs and meta-data. In this paper, we implement storing house logs and Scallop4SCAPIs based on previous work, and implement concrete application using Scallop4SC. And we discuss about the current state of Scallop4SC.

In these researches, the devices that measure the user such as accelerometer and GPS are mainly used. On the other hand, environmental data like temperature and humidity is measured by fixed devices. It enables to get detailed and valuable information by means of that users privately measure these data by mobile terminal. In this paper, we discuss that what kind of value-added services can be realized by users carrying on the mobile sensors and measuring the environmental data. We also carry out the case study with prototype of mobile sensor.

  Smart city is a next-generation societal concept which aims to provide low-carbon and sustainable social infrastructure. In the smart city environment, wide variety of city data are retrieved from sensors. Social services are provided from the collected data for smart city residents. In this paper, we propose a smart city platform, called Scallop4SC that supports collecting and using the extremely large-scale log data. The Scallop4SC constructs a distributed multi-node infrastructure using Hadoop and HBase, and provides high-scalablity and high-performance data processing for petabyte scale data. We conduct an experimental performance evaluation of the proposed platform using actual house log obtained in our smart home environment Based on the results, we discuss the applicability of Scallop4SC in city scale log data processing.

  We have previously proposed the ReceiptLog, which stores user's purchase histories from daily receipts for value-added consumer services. As a practical application of the ReceiptLog, we design and implement a shopping support service, called "Sma-Sho", in this paper. Sma-sho is designed to cope with two typical problems in daily shopping: duplicate purchase and forgotten purchase. The duplicate purchase is that a user mistakenly buys a product although there is sufficient stock of the same product at home. The forgotten purchase is that a user forgets to buy a product although the product is out of stock. Using the ReceiptLog APIs extensively, Sma-Sho provides useful purchase histories for the user with a mobile terminal, to prevent the above two problems. We also conduct an experimental evaluation with 8 subjects, to show the effectiveness of the proposed method.

• An Application Framework for Developing Visualization Services of Location based Lifelog

  Kohei TAKAHASHI, Akira SHIMOJO, Shinsuke MATSUMOTO, Masahide NAKAMURA

  This paper presents an application framework, called MashMap framework, which facilitates development of location-based lifelog services. The proposed framework imports various types of location log data, and stores them in a database with the Life Log Common Data Model (LLCDM). A developer first creates a data source consisting of a filter and a display format. The filter extracts necessary data from the database, while the display format defines how the data is shown on the map. The developer then defines a MashMap by choosing a single or multiple data sources. The MashMap is an object, which aggregates several data sources on a single map, shown in the designated display format. The object is finally visualized on a Google Map by MashMap renderer. We conduct a case study developing a travel log review service and a conference history map using MashMap framework.

• Redefining Environment Feature Interactions in Home Network System Based on Nature of Environmental Impacts

  Ikegami Kousuke, Inada Takuya, Matsumoto Shinsuke, Nakamura Masahide

  The integrated services of the home network system (HNS) orchestrate multiple networked home appliances to achieve value-added and comfortable services for home users. If multiple services are used at the same time, functional conflicts may occur among the services, which results in unexpexted behaviors. This is known as feature interactions (FIs). We defined two kinds of FIs : appliance interactions and environmental interactions. Due to lack of the degree of environmental impact and explicit consideration of requirements, the previous formalization tends to overestimate many acceptable cases as feature interactions. To capture the environment interaction more precisely, this paper introduces an environment impact model, describing how much impact is given to the environment by each appliance operation within a service. We also describe user requirements by environment properties evaluated within the model. Then, the environment interaction is formalized as the unfulfilled requirement caused by the use of multiple services.

• A Feasibility Study of Home Services Using a Microphone Array Network

  Shimpei SODA

  The home network system (HNS), which provides value-added services by orchestrating networked home appliances, equipments and sensors, attracts great attention to realize the next-generation smart home. Implementing the location-aware services within the the HNS context is one of greatest challenges, where the appropriate services are performed based according to the location of the inhabitants. We have been studying the technologies of sound source localization and sound source separation using networked multiple microphone arrays. In this paper, we conduct a feasibility study of applying the microphone array network to the location-aware services within the HNS. Specifically, we first present three kinds of home services using illustrative examples. We then enumerate three kinds of requirements (accuracy requirement, installation requirement, user requirement), which are essential for implementing the location-aware home services using the microphone array network. In a preliminary experiment, we evaluate the accuracy requirement using an actual microphone array. Moreover, we conduct a directivity shape simulation assuming multiple arrays.

  We have been studying the personalized energy-saving behaviors using the Home Network System (HNS). In this paper, we propose a method that finds personalized energy-saving behaviors in air conditioning services. Specifically, we first extract user's preference to energy-saving, air conditioning and appliances, by conducting a preliminary questionnaire. Using the preference of each user, we then formulate an optimization problem on preferred appliance operations and the power consumptions. By solving the problem, we derive a personalized energy-saving air-conditioning service. To demonstrate the effectiveness, we conduct an experiment with fifteen subjects in an actual HNS.

• Evaluating Lifelog Common Data Model and Mashup API through Practical Application Development

  Akira Shimojo, Shinsuke Matsumoto, Masahide Nakamura

  In order to support efficient integration of heterogeneous lifelog services, we have previously proposed the lifelog common data model (LLCDM) and the lifelog mashup API (LLAPI). In this paper, we evaluate the efficiency of the LLCDM and the LLAPI through a practical application development project. Specifically, we implement two versions of an integrated lifelog application with and without the LLCDM and the LLAPI. We compare the two versions from viewpoints of the quality of the product as well as the efficiency of the development process.

• Evaluating Habituation Effect on Conversational Voice Control in Home Network System

  Noriyuki MATSUBARA, Shinsuke MATSUMOTO, Masahide NAKAMURA

  The voice control is an easy and effective method to operate heterogeneous devices in the home network system (HNS). However, as the user is getting used to the interface, too much feedback from the system annoy the user and decline the usability. In this paper, we empirically evaluate the habituation effect on the voice control in the HNS. Specifically, we characterize the habituation effect by the time since the system begins the feedback until the user issues the next command. Based on the empirical study, we consider a voice feedback method that adapts the individual habituation.

• ReceiptLog: A Consumer-Oriented Lifelog Service for Storing and Reviewing Daily Receipts

  Seiki Tokunaga, Shinsuke Matsumoto, Masahide Nakamura

  We have previously implemented the receipt service platform, where consumers can digitize their own receipts for various applications and services. In this paper, we develop a consumer-oriented lifelog service, called ReceiptLog, by using the receipt service platform. Using the purchase history obtained from the receipts, the ReceiptLog extensively supports every end user to review daily life from financial and living viewpoints. Moreover, we also study more value-added services by integrating other lifelog services with the ReceiptLog.

• Recording Receipts for Consumer-Oriented Lifelog Services

  Seiki TOKUNAGA, Shinsuke MATSUMOTO, Masahide NAKAMURA

  Consumer's past purchase data has been used to tool and to serve for the seller and suppliers of the trend analysis and the sales strategy decision, etc. so far. In this paper, it proposes "consumer-oriented lifelog services" which is used to suport their facet of living and health aspect. Concretely, the end user oneself accumulates receipt information as a life log, and service that supports health aspects on the life side of the user is examined. Moreover, we design API that becomes useful for implementation service. In addition, we think that when oriented-lifelog it aims at the achievement of high service of the additional value or more by combining with other life log services.

• Implementing Database and Web Services for Life-Log APIs

  Akira Shimojo, Shinsuke Matsumoto, Masahide Nakamura

  We have previously proposed the LifeLog Common Data Model (LLCDM) to aggregate heterogeneous lifelog data, and the LifeLog mashup API (LLAPI) to access the standardized data. The LLAPI was implemented as a set of Perl libraries that access the local file system storing XML data of the LLCDM. Therefore, it had a performance bottleneck, and was poor in the portability. To cope with these problems, we re-engineer the LLCDM and the LLAPI with the relational database MySQL and the Web services, respectively. The experimental evaluation shows that the performance of the new implementation achieves 23 to 275 faster than the previous one.

• Design and Evaluation of End-User Development Environment for Context-Aware Services in Service-Oriented HNS

  MATSUO Syuhei, MATSUMOTO Shinsuke, NAKAMURA Masahide

  The home network system (HNS, for short) provides value-added and context-aware services for home users, by orchestrating networked home appliances and sensors. Although the HNS services have been developed by system vendors, there exist strong needs that the end-users create their own services according to their convenience. This paper presents a novel service creation environment, called Sensor Service Binder (SSB), which provides a user-friendly interface for creating context-aware services within the HNS. Built on top of the service-oriented HNS, the SSB allows non-expert users to register contexts using the sensors, and to bind the registered context to any operation of the networked appliances. Experimental evaluation with an actual HNS showed that the effort for service creation was reduced to 10% by introducing the proposed SSB.

• Developing Home Network Services with Feature Interaction Detection and Resolution System

  Takuya Inada, Yuhei Yoshimura, Kousuke Ikegami, Hiroshi Igaki, Masahide Nakamura

  As one of the major Home Network System, the integrated service of networked home appliances are proposed. When such integrated services are executed simultaneously, functional conflicts can occur between the functions of each appliance. Such conflicts are called Feature Interaction in HNS. In our precedence research, we proposed an feature interaction detection and resolution mechanism based on service-oriented architecture (SOA). In this paper, we propose new software development process for integrated services in HNS. In our process, we adopt a specification template for integrated services, simulation for feature interactions detection and resolution, and automatic transformation service specifications into implementations. In our comparative experiment, we confirmed our development process is more useful to develop reliable integrated services effectively than that of conventional development.

• A Proposal of Service Registry for Discovering Service Resources in UBiquitous Network

  Hideharu SETO, Kouichi EGAMI, Syuhei MATSUO, Hiroshi IGAKI, Masahide NAKAMURA

  In the future ubiquitous network, it is expected to realize an adaptive service platform, which dynamically integrates various service resources to provide adaptive and context-aware services. This paper presents a service registry, called Ubi-Regi, in order to support efficient and dynamic discovery of service resources in the ubiquitous network. Ubi-Regi categorizes every service operation into one of three types: Source, Transformation or Sink service, to define the scope of the operation within the real and IT worlds. Also, it associates every resource with the physical location and the goal keywords, so that the resource can be searched by place or purpose. This paper first conducts data modeling of Ubi-Regi. We then design and implement Ubi-Regi APIs as data accessors. We demonstrate its feasibility through a case study of the environment migration service in a home network system.

• Sensor search with spatial information and support by showing similar parameter for building sensor context

  MATSUO Syuhei, SETO Hideharu, SAKAMOTO Hiroyuki, IGAKI Hiroshi, NAKAMURA Masahide

  In a home network system, a context-aware application is one of the value-added services. The application controls various appliances based on a context which is estimated by various sensors in the home network system. In our precedence research, we proposed "a Sensor Service Binder(SSB)" which facilitate the development of the context-aware applications by integrating the context and the appliance. However, our SSB needs the contexts and the appliances information which are registered by specialist, in advance. In order to register the contexts, a developer must know sensors which is used in the contexts, and define the condition equation by himself. In this paper, we propose SSB 2.0 supporting to register contexts by end-users. The SSB 2.0 realizes a sensor search service with using place information of sensors, and a context search service with using context registration history. Our SSB 2.0 supports a series of the development process from the context registration to the context and appliance integration for the context-aware application.

• A Standardized Data Model for Networked appliances in Home Network System

  EGAMI Kouichi, IGAKI Hiroshi, NAKAMURA Masahide

  Various Home Network System (HNS) services are being widely developed. HNS appliance information and its data structure in such conventional services differ. As a result, the services and HNS appliances are tightly-coupled. This causes the implementation of the services becomes more complicated. In this paper, we propose a hierarchical HNS appliance data model for improving reusability. Our data model has three layered structures (1) Standardized appliance class information independent of several HNS environment (2) Appliance information included in a HNS environment independent of services (3) Service-specific appliance information. We applied the data model for multiple services, and verified effectiveness.

  The building automation system (BAS, for short) provides efficient management features of building equipments as well as various value-added services. According to the progress of network infrastructure, it is expected, in the near future, to achieve more value-added and sophisticated services by integrating multiple BASs over the network. However, the integration of heterogeneous systems yields complexity of the systems as well as the service interaction problem. To cope with these problems, we propose a modeling method for the BAS. Specifically, we characterize a BAS by sets of equipments and service scenarios achieved by the equipments. We then formulate conditions that the system itself operates consistently and compatibly. We also present a method for detecting service interactions between multiple BASs. Using the proposed model, we have conducted a case study, where 10 practical systems and 33 service scenarios were analyzed. Moreover, for 466 pairs of service scenarios, we could successfully detect 34 service interactions.

  Many value-added services for building controls have come onto market recently. Most of the conventional systems adopt a closed communication architecture, where each system controls target building equipments by a proprietary protocol. In this paper, we propose a framework that can create new value-added services by integrating the existing systems. To achieve this, we extensively use the service oriented architecture (SOA). We also discuss the safety issues caused by the functional conflicts among heterogeneous services.

  The users of Web service have been given chances to select the high quality services from many services, because of the increase of Web services with the advances of Web service technology. Some technologies which measure the quality of Web service quantitatively are needed to compare the quality as services. However, many existing studies focus on the individual Web service, therefore there is no effective methods of quality measurement is established for integrated Web service. In this paper, we propose a method which estimates the quality statistically as one of the methods of quality measurement for integrated Web service. Associating an operation with each of structural constructs derived, we translate the given workflow into a formula, from which we derive the estimation of the response time and the availability of the composite Web service.

  Recently, some researches and developments of Event Driven Architecture (EDA) are in progress. This architecture is distinctive by invoking Web services by the specific event defined by users. The specification of many EDA frameworks can be complex and huge scale sometimes because it is designed to correspond to every kind of events. Therefore, there is large amount of cost when applying this architecture to the Web service which handles only specific events. In this paper, we propose a Web services invocation framework "WS-Schedule Manager" which is specified with "Time event." The framework invokes a Web service at the specified time after a user set the Web service, parameters and their time schedules. The specification of this framework is compact and lightweight to execute because it is specialized to handle the time driven invocation of Web service, so this framework can be used by embedding various Web service applications. We also consider about some case studies such as wakeup service on Home Network System in this paper.

  Home network system which includes networked home appliances and a home network are becoming popular remarkably. As a result, the several value added services to integrate multiple networked appliances are being provided by the home network system. In this paper, as the kind of a new value added service, we propose a room state migration service. This service supports to integrate the appliance methods when a user moves in the inside of a home which consists of multiple rooms, For example, suppose that a user in a living room moves to a bed room. The following two are examples of the scenario which our service can support. (1) A user continues watching a TV program which was being watched in the living room also in the bed room. (2) A user makes the state of the environment (such as room temperature and brightness) of the bed room the same as the living room. Thus, a user's convenience can be improved with our service supporting the appliance orchestration for making the state of the rooms equal continuously.

  This technical report proposes a software tamper proofing method called instruction folding. In this method, a set of similar (but sligtly different) instruction sequences is detected in a program, and then, they are integrated (folded) into a single instruction sequence. A self-modifying mechanism is applied to the folded sequence to bridge the gap between those slightly different sequences at run-time. The folded sequence is tamper resistant since tampering affects every functionality where original (similar) instruction sequences were present.

  We propose a new metric that measures the reusability in case of migrating from legacy system to service-oriented system (SOA), and a method to measure the metric. First of all, we compare two services in functional aspects; the first one, we call this necessary service, is a service which is obtained by analyzing business process using top-down approach. The second one, we call this candidate service, is a service which is obtained by analyzing source codes using bottom-up approach. Then, we analyze how exiting candidate services are reusable to realize necessary services. Finally, we measure the ratio of the reusable legacy system based on size metrics. As a result of applying proposal technique to existing liquor management system, we could confirm that we are able to measure potential reusability ratio of the service in the existing system quantitatively.

• JMLを用いたホームネットワークシステムにおける連携サービスの安全性検証に関する提案

  Ben Yan, Masahide Nakamrua, Lydie du-Bousquet, Ken-ichi Matsumoto

  The recent ubiquitous technologies allow home electric appliances and sensors to be connected with local area network at home. While when we develop such HNS (Home Network System) integrated services and provide them to the users, we must assure that the integrated services are safe for the users, the appliances and the environments. In the normal operations of these appliances are very different from the operations of the HNS, so the development and the implementation of the HNS integrated service need more careful and exact safety measures for the safe operations of the appliances. There is a possibility that the bug and the logic mistake of software cause an accident and serious damage. In order to solute this problem, we present a framework to verify the safety of integrated service of HNS by using the DBC(Design by Contract) and JML(Java Modeling Language)

• ホームネットワークにおける家電連携サービスのユーザビリティ評価

  Naohiro YUASA, Makoto IHARA, Masahide NAKAMURA, Ken-ichi MATSUMOTO

  Currently, Home Network System (HNS) attracts a great deal of attention. This system can provide value-added services with connecting various home appliances to the network. We have already developed an integrated service which enables the integrated operation of more than one home appliance with using Web services in our previous study. In this paper, we did an evaluative experiment of the integrated service to show its utility in HNS. In this experiment, we set some typical tasks with operations of the integrated service and consumer appliances, and then we conducted usability testing to operate the appliances by the subjects actually. In the evaluation, we evaluated from the viewpoint of the operation efficiency and the satisfaction rating by comparing the operations of each usual appliances and integrated service in HNS. We were able to confirm that all subjects completed the tasks of the integrated service from this experiment. Moreover, we could obtain the result in which the average operation time was a half or less in the maximum, and the average number of errors was 1/10 or less in the integrated service compared with the usual operation. We were also able to obtain the result that the satisfaction rating of the service was 1.5 times or more high in the integrated service compared with the usual operation in all tasks.

• ホームネットワークシステムにおけるサービス開発へのペルソナシナリオ法の適用と評価

  Makoto IHARA, Hiroki SAKAKIBARA, Naohiro YUASA, Masahide NAKAMURA, Ken-ichi MATSUMOTO

  Currently, some researches and developments about Home Network System (HNS) which provide more convenient, comfortable life with using various services on the network are in progress. However, there is no service provided which is beneficial and value-added for users, therefore this system has not become popular yet. In this paper, we introduced Persona-and-Scenario method to service development of the system. This method is representative to propose and implement the services because of it is from the viewpoint of the users, not from the viewpoint of the developers. We also implemented "Today's recipe service", which is one of the services extracted by the method. We then took an evaluative experiment by usability testing with some actual users. As a result of the experiment, we found that the assessment of the services we developed was the highest by age 40's mothers who are closest to the main persona we created. We confirmed the utility to apply Persona- and-Scenario method onto services development of the HNS from this result.

  This paper proposes an authentication method using location and speed information for mobile users. Though passwords or PINs is widely used for authentication, an incorrect user could be authenticated, peeking at a user inputting a password or PIN. With proposed method, users are authenticated when they sequentially pass through some points with specific speed. They are not authenticated when passing speed on the point is different from specific speed. This paper proposes the authentication method and confirms that location and speed information can be used for authentication by exploratory experiment.

• Java Birthmarks : Detecting the Software Theft

  TAMADA Haruaki, NAKAMURA Masahide, MONDEN Akito, MATSUMOTO Ken-ichi

  To detect the theft of Java class files efficiently, we propose a concept of Java birthmarks, which are unique and native characteristics of every class file. For a pair of class files p and q, if q has the same birthmark as p's, q is suspected as a copy of p. Ideally, the birthmarks should satisfy the following properties : (a) preservation - the birthmarks should be preserved even if the original class file is tampered with, and (b) distinction - independent class files must be distinguished by completely different birthmarks. Taking (a) and (b) into account, we propose four types of birthmarks for Java class files. To show the effectiveness of the proposed birthmarks, we conduct three experiments. In the first experiment, we demonstrate that the proposed birthmarks are sufficiently robust against automatic program transformation (93.3876% of the birthmarks were preserved). The second experiment shows that the proposed birthmarks successfully distinguish non-copied files in a practical Java application (97.8005% of given class files were distinguished). In the third experiment, we exploit different Java compilers to confirm that the proposed Java birthmarks are core characteristics independent of compiler-specific issues.

• 家電機器間の相互接続性を考慮した連携サービスを実現するサービス指向フレームワークの提案

  Hiroshi Igaki, Masahide Nakamura, Ken-ichi Matsumoto

  With integrated services which make two or more appliances orchestrate, an appliance framework in consideration of an interoperability problem between multi-vendor appliances should be needed. To achieve the interoperability, this paper presents a service-oriented framework for multi-vendor home network systems(HNS). We propose a two-layered design of an appliance, consisting of device and service layers. The device layer corresponds to the physical device of the appliance controlled by vendor-specific interfaces. The service layer exhibits features of the device as self-contained services accessible via device-independent interfaces. In our proposed framework, every integrated services are realized by these appliances appliances which adopt the design. Such self-contained appliances enable high interoperability between them.

• Webサービスアプリケーションのプロトタイピング および性能評価のためのシステム開発

  Ken-ichi Ishii, Youhei Kushido, Hiroshi Igaki, Masahide Nakamura, Ken-ichi Matsumoto

  This paper proposes a general framework, called WS-PROVE (Web Service PROtotyping Validation Environment), for rapid prototyping of Web service applications. In a requirement definition stage, WS-PROVE first abstracts a Web service under development as a dummy, and then integrate the dummy with other dummies or the existing ready-made Web services in arbitrary topologies. For a given configuration including the integration topology, processing time for each service and the network delay, WS-PROVE dynamically connects the Web services. Then, it measures the response time for each service and the whole integrated services. In this paper, we first clarify system requirements of the rapid prototyping system for Web service applications. Then, we present design and implementation of WS-PROVE. Additionally, we conduct a case study to prototype some Web service applications to demonstrate the effectiveness of WS-PROVE.

  In this paper, we evaluated in experiments the relationship between the quality of Web Service applications and the Web Service Metrics (RFWS, NOWS, and NHTWS) that have been proposed by our research group. First, the performance of Web Service application was measured using WS-PROVE developed so that we could build the prototype of Web Service application topology freely, and considered the relationship with Web Service Metrics. Next, the reliability of Web Service application was calculated using the reliability assessment algorithm "Sum of Disjoint Products (SDP)", and considered the relationship with Web Service Metrics. As a result, we revealed experimentally a relationship between Web Service Metrics and the quality of Web Service applications.

  This paper presents a method to estimate the cost of mental simulation of programs. In our previous research, we developed a model called virtual mental simulation model (VMSM). It showed that a distance of simulation backtrack significantly influences the cost of mental simulation. Through the subsequent experiments, however, we have found some cases that are not well justified by the distance only. In this paper, we show that updates of variables in a program also have significant correlation to the mental simulation. Then, we propose two new dynamic metrics: Sum in Number of Variable Updates and Variance in Number of Variable Updates. The experimental evaluation shows that the proposed metrics well explain the cases the previous VMSM cannot cover.

• 家電機器連携サービスにおけるサービス競合検出システム

  Hiroshi Igaki, Masahide Nakamura, Ken-ichi Matsumoto

  The integrated services are one of the major applications of the home network system. Features of multiple networked appliances are combined to provide more comfortable living for home users. When multiple integrated services are executed simultaneously, the features executed in the services may conflict with each other. This conflict is generally known as the feature interaction problem, which decreases the total quality of services. This paper formulates the feature interaction problem in the integrated services of the home network system. Specifically, we define two types of interactions: device interactions and environment interactions. The device interactions are direct conflicts of features on the same device, whereas, the environment interactions are indirect conflicts on certain environment properties. We conduct a case study of interaction detection to demonstrate the effectiveness of the proposed method.

  Yuichiro Kanzaki, Akito Monden, Masahide Nakamura, Ken-ichi Matsumoto

  In this paper, we present a new method to protect software against illegal acts of hacking. The key idea is to add a mechanism of self-modifying codes to the original binary program, so that the original program becomes hard to be analyzed. In the binary program obtained by the proposed method, the original code fragments we want to protect are camouflaged by dummy instructions. Then, the binary program autonomously retrieves the original code fragments within a certain period of execution, by replacing the dummy instructions with the original ones. Since the dummy instructions are completely different from the original ones, code hacking fails if the dummy instructions are read as they are. Moreover, the dummy instructions are scattered over the program, therefore, they are hard to be identified. As a result, the proposed method helps to construct highly invulnerable software without special hardware.

• Experimental Evaluation of Interaction-Prone Scenario Derivation Method in Feature Interaction Filtering

  LEELAPRUTE Pattara, NAKAMURA Masahide, KIKUNO Tohru

  Feature Interactions(FI, in short) are functional conflicts among features of telecommunication services. Since detecting all possible FIs takes huge costs, the technology of FI filtering is emerging, which roughly identifies FI-prone service combinations with simple indications. However, the previous filtering identifies the FI-prone combinations only. It cannot derive concrete scenarios in which potential FIs may exist. So, we have proposed a new scenario derivation method for FI-prone combinations. The goal of this paper is to evaluate the scenario derivation method. The evaluation is conducted with respect to scenario coverage and filtering quality, using specifications of FI detection contest. The result shows that the proposed method have covered all FI scenarios detected in the contest.

• Feature Interaction Classification for Services in CPL

  TAKI TOMOKAZU, NAKAMURA MASAHIDE, KIKUNO TOHRU

  The recent advancement of the Internet technologies prompts the Internet telephony services for practical use. In the Internet telephony, implementation of user-made services is an important concern, and a service description language CPL(Call Processing Language) is proposed in RFC of IETF. Managing such services in the Internet telephony is up to users, thus users can freely deploy very flexible services. However, new types of the feature interaction problem may arise, which are not seen in the traditional centralized telephone network. In order to clarify the feature interaction in the Internet telephony, this paper categorizes functional conflicts of services written in the CPL. Specifically, we focus on a case where the CPL scripts of two services are deployed in the same server. Then, we define four classes of the interactions according to the structure of CPL tags. Also for each class, we discuss some idea towards resolution of the interactions.

  Feature interaction is known as a kind of conflicts among service functions in the communication system to which new communication services are added. It is strongly required to establish the efficient detection and elimination method for feature interactions. We have already proposed a new detection algorithm Ω for nondeterministic feature interactions, which utilizes P-invariant of Petri-Net. The goal of this paper is to evaluate the usefulness of the proposed method by applying it to practical telecommunication services. The experimental results show that proposed method attains high quality of detection and good scalability, and that it is well applicable to the interaction detections of practical services

• Detection algorithm for non-deterministic feature interactions using Petri-net

  Masahide Nakamura, Yoshiaki Kakuda, Tohru Kikuno

  Feature interaction is known as a kind of conflicts of service functions, Which arise when a new communication service is added to the existing communication system. For feature interactions, it is strongly required to establish the systematic detection and elimination method. Since the conventional detection methods generally require the state enumeration based on reachability analysis, and thus cause the state explosion problem, they cannot be applied to complex service specifications assuming many users. In order to overcome this problem and detect non-deterministic feature interactions, We have already proposed a new detection algorithm Ω based on a Petri-Net model. By using P-invariant of the Petri-Net, the algorithm Ω can detect the non-deterministic interactions without any state enumeration. The goal of this paper is to give the formal proofs for the correctness of the algorithm Ω. Then we also discuss the applicability of the P-invariant to other types of feature interactions.

• A synthesis method for fault-tolerant multipath routing protocols in connectionless networks

  Yutaka Hatanaka, Masahide Nakamura, Yoshiaki Kakuda, Tohru Kikuno

  Routing Protocol synthesis problem discussed in this paper is the problem to derive a routing protocol specification modeled by FSM from a given routing specification modeled by FSM. In this paper, we propose a synthesis method to solve the routing protocol synthesis problem in connectionless networks such that each message can be delivered from its source node to its destination node through relay nodes even when a node or channel fails. The key ideas of the proposed method are as follows. (1) Primitives exchanged between users and source or destination nodes in the service specification are projected to the protocol specification of each protocol entity. (2) Using the transition synthesis rules transitions for directly delivering messages from the source node to the destination node are generated in the protocol specification of the source and destination nodes. (3) Transitions for delivering message through the loop-free communication paths from the source node to destination node generated in the protocol specification of the related nodes.

  Protocol synthesis is a method for designing communication protocols reliably and efficiently.The previous synthesis methods assume that primitives cannot be executed simultaneously at different SAPS.If concurrent primitives are executed at the different SAPS,protocol errors of unspecified receptions and dead locks occur. In this paper,we extend a class of service specifications from which protocol specifications are synthesized by the previous methods to a class of service specifications with parallel execution of primitives. We first introduce the priority of primitives such that when parallel execution of primitives occurs the execution assigned higher priority takes precedence over that assigned lower priority. Based on this idea,we propose a new protocol synthesis algorithm for avoiding the protocol errors due to message collision, communication competition and so on. By applying this method,protocol specifications can be automatically synthesized from service specifications which have an arbitrary number of processes and which allow parallel execution of primitives.
