As its cost declines and function extends, RFID is gradually replacing the traditional barcode systems. Low-cost RFID tags are anticipated to be widely used in our daily life. However, owing to the radio transmission nature of RFID, the information transmitted in the air could easily be eavesdropped on, intercepted, or modified. Because low-cost RFID tags are with extremely limited resources, traditional security primitives can not be incorporated well. In 2007, Chien proposed the ultralightweight strong authentication and strong integrity (SASI) protocol for low-cost and very low-cost tags. The protocol is a highly efficient RFID authentication protocol using only simple bitwise operations on tags. However, the scheme is found suffering from tracking and denial of service attacks. This paper will give demonstrations on what have caused these weaknesses, and more of that, an improved protocol is also proposed which is free from worries of those possible attacks. The improved protocol could thus be applied in environments demanding high security.","PeriodicalId":284323,"journal":{"name":"2009 Joint Conferences on Pervasive Computing (JCPC)","volume":"76 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123944750","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

But most of pervasive systems are not quickly suitable for mobile device. In order to provide adaptive mobile services, the approach for self-adaptation is proposed in this paper. Firstly, context of mobile devices and its influence on pervasive application are analyzed and business rules based on this analysis are presented. Then, using the approach, the pervasive system is constructed. The example implies this approach can detect the contextual environment of mobile computing and adapt the mobile service to the mobile devices flexibly.","PeriodicalId":284323,"journal":{"name":"2009 Joint Conferences on Pervasive Computing (JCPC)","volume":"48 3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124389132","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The proposed scheme embeds watermark on all AC coefficients of 4×4 DCT blocks of I-frames. It integrates Watson's human visual system and the contents of 4×4 DCT blocks to determine the embedding strength. Since the high correlation of the video content within one scene, producing similar embedding strength, the scheme has the property of same watermarks for same scenes and different watermarks for different scenes. Thus, it can successfully resist the collusion attacks. Experiments validate that the proposed scheme has advantage of the invisibility, and it is robust to collusion attacks as well as H.264 compression.","PeriodicalId":284323,"journal":{"name":"2009 Joint Conferences on Pervasive Computing (JCPC)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121324441","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The rule-space model approach supports cognitive analysis of student's network technologies skill. And then to comprehensive what learning tops are weaknesses or strengths by individuals. The learner's relevance feedback provided user's evaluation that contained the item difficulty. We implemented a web testing application for ITE testing simulation.

However, lacking of intelligent guide is a critical problem in assembly design with VA technology. This paper proposes a novel concept of context-aware in VA, and discusses the connotation and extension of it. Such context should be a small world context that provided intelligent for virtual environment, while an ontology-based working model and architecture are presented to realize it. A decision-making arithmetic is also composed based on Quotient Space Theory, which supports the VA system to compute assembly context real-time in condition of different assembly granularity. By deploying this method, VA need no longer to be viewed only as an interactive tool or environment for judging feasibility of assembly, but rather as an virtual intelligent task processor that can offer decision service to assembly task based on application needs.","PeriodicalId":284323,"journal":{"name":"2009 Joint Conferences on Pervasive Computing (JCPC)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128298858","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Though many interactive speech recognition systems using candidate selection are developed for English and Japanese, similar systems for Chinese face particular difficulties due to characteristics of the Chinese language, especially at the candidate generation stage. In this paper, a method is proposed for candidate generation in interactive Chinese speech recognition, which lists all competitive candidates in forms of Chinese characters in stead of words. The main idea is to align time-overlapped links in Chinese word lattice into clusters based on their phonetic similarity, and then obtain candidates by splitting words attached to links into Chinese characters. Experimental results demonstrated that the candidates generated by the proposed method can lead to high performance in interactive Chinese speech recognition.","PeriodicalId":284323,"journal":{"name":"2009 Joint Conferences on Pervasive Computing (JCPC)","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128343698","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the real world, services are heterogeneous. The most popular services are SOAP/WSDL services and Web applications. The heterogeneous services bring challenges to service integration and orchestration. Prior attempts use adapters or converters to mask the heterogeneity and host alien services, which potentially lead to inefficiency. This paper reviews the current techniques for heterogeneous services integration and orchestration. Comparing different techniques' strengths and weaknesses, this paper presents a hybrid orchestration approach that make use of the heterogeneous nature of the services for efficient orchestration. The proposed approach can be used for large scale efficient integration of numerous disparate services (e.g. SOAP/WSDL services and RESTful services).","PeriodicalId":284323,"journal":{"name":"2009 Joint Conferences on Pervasive Computing (JCPC)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125113501","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
