A commonly accepted solution for providing fault tolerant services on the Internet is to create replica of the services and to deploy them to several hosts. Whenever the service or the underlying node or network fails, another service is ready to take over. In the Venice project, several techniques are combined to create a dependable framework for deploying and managing distributed services using replica on several distinct network nodes.","PeriodicalId":433802,"journal":{"name":"International Conference on Next Generation Web Services Practices (NWeSP'05)","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122015127","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}

It can protect against ID-theft, replaying, forgery, guessing, insider, and stolen verifier attacks. However, this paper shows that Das, Saxena, and Gulati's scheme has some attacks. Therefore, we propose a slight modification to their scheme to improve their weaknesses. As a result, the improved scheme can enhance the security of Das, Saxena, and Gulati's scheme. In addition, the proposed scheme does not add many computational costs additionally. Compare with their scheme, our scheme is also efficient.","PeriodicalId":433802,"journal":{"name":"International Conference on Next Generation Web Services Practices (NWeSP'05)","volume":"208 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115751311","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}

Global access to information makes security, namely the authentication process, a critical design issue in these systems. In what concerns to authentication, what is required is a reliable, hardware independent and efficient security system. In this paper, we propose an extension to a keystroke dynamics based security system. We provide evidence that completely software based systems can be as effective as expensive and cumbersome hardware based systems. Our system is a behavioral based system that captures the normal typing patterns of a user and uses that information, in addition to standard login/password security to provide a system that is user friendly and very effective at detecting imposters. The results provide a means of dealing with enhanced security that is growing in demand in Web based applications based on e-commerce.","PeriodicalId":433802,"journal":{"name":"International Conference on Next Generation Web Services Practices (NWeSP'05)","volume":"81 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122360245","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 typical approach to querying such dynamic sources is polling for updates often. This strains the traditional pull-based Internet and wastes network resources on transmitting redundant information. This paper focuses on how to structure the Internet to avoid the unnecessary client-server interactions dominating the Internet. To that end, we extend the API of popular existing Internet services through Web service wrappers. These wrappers use the API of, for instance, Google, but provide functionality that is richer. Initial experience shows that major performance gains can be achieved through this approach.","PeriodicalId":433802,"journal":{"name":"International Conference on Next Generation Web Services Practices (NWeSP'05)","volume":"60 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122515306","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}

Those requirements allow the user to deal with a lot of learning objects anytime and anywhere in simple handhelds. The integration provided by Internet and mobile device changes the developer methodologies to the issue of creating new subjects. The question that then arises is no longer \"how to produce the software I need\", but \"where to find it and how to integrate it with the software already used in devices to construct a customized educational environment\". Integrations imply modifications in the source code, usually requiring hard work on source code modifications with a high cost. However, those environments are still developed in a monolithic way, out of a development view based on a composition of learning objects, much easier to match. This paper describes a architecture which promotes software integration through the utilization of Web services.","PeriodicalId":433802,"journal":{"name":"International Conference on Next Generation Web Services Practices (NWeSP'05)","volume":"65 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117173426","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}

Not only that Internet pricing is an important business concern, it also represents a feasible solution to many managerial problems in network operations, such as resource allocation, congestion control, and quality of service guarantee. We have surveyed prominent Internet pricing schemes and the lessons learned have enabled us to develop a pricing model that satisfies multiple design objectives: network efficiency, economic efficiency, user utility and practicality. An illustrative example scheme is devised using the model. Quantitative analysis and qualitative evaluation have shown that the proposed scheme indeed meets the design criteria and expectations.","PeriodicalId":433802,"journal":{"name":"International Conference on Next Generation Web Services Practices (NWeSP'05)","volume":"58 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125121696","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}

Context is any relevant information describing entities in a user-computer interaction (e.g. user location). The design and implementation of high-quality context management software is an area of active research. We have described elsewhere the context kernel, a Web service that manages context information on behalf of applications. In this paper, we present a case study of how the context kernel has been used to integrate a suite of e-learning applications. We show how the Web services approach allowed applications to seamlessly exchange context on the Web through a uniform context representation schema.
