We reviewed all papers from the ACM CSCW conference (1990-1998) that introduced or evaluated a groupware system. Forty-five papers were included in the review. The main findings are that almost one-third of the groupware systems were not evaluated in any formal way, that only about one-quarter of the articles included evaluations in a real-world setting, and that a wide variety of evaluation techniques are in use. Our main conclusions from the review are that more attention must be paid to evaluating groupware systems and that there is room for additional evaluation techniques that are simple and low in cost.","PeriodicalId":435283,"journal":{"name":"Proceedings IEEE 9th International Workshops on Enabling Technologies: Infrastructure for Collaborative Enterprises (WET ICE 2000)","volume":"233 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2000-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122456765","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}

Hierarchical PKIs may be appropriate solutions for many usage-scenarios, but there exists the viable alternative of the 'Web of Trust'. In a web of trust, each user of the system can choose for himself whom he elects to trust, and whom not. After contrasting the properties of web-of-trust based PKIs to those of hierarchical PKIs, an introduction to webs of trust and to quantitative trust calculations is given. The paper concludes with the presentation of an efficient, sub-exponential algorithm that allows heuristic computations of trust paths in a web of trust.","PeriodicalId":435283,"journal":{"name":"Proceedings IEEE 9th International Workshops on Enabling Technologies: Infrastructure for Collaborative Enterprises (WET ICE 2000)","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2000-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126774706","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 principal motivation behind RBAC is to simplify administration. Several framework for the development of role-based systems have been introduced. However, there are a few works specifying RBAC in a way which system developers or software engineers can easily understand and refer to develop role-based systems. The Unified Modeling Language (UML) is a general-purpose visual modeling language in which we can specify, visualize, and document the components of a software system. In this paper we represent the RBAC model with this well-known modeling language to reduce a gap between security models and system developments. We specify the RBAC model with three views: static view, functional view, and dynamic view. In addition, we briefly discuss about the future directions.","PeriodicalId":435283,"journal":{"name":"Proceedings IEEE 9th International Workshops on Enabling Technologies: Infrastructure for Collaborative Enterprises (WET ICE 2000)","volume":"116 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2000-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127993756","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}

These applications require design methodologies that are far from being well established and new standard technologies models, languages, technologies and tools specifically tailored to the agent metaphor and to agent-based systems. This article presents LuCe, a coordination infrastructure for the design and the development of agent-based distributed applications on the Internet, which integrates Java logic-based languages, and tuple-based coordination models. We discuss the impact of this approach on the design both of the single agents and of Internet applications, then suggest how it could be exploited in the design/development/test cycle.","PeriodicalId":435283,"journal":{"name":"Proceedings IEEE 9th International Workshops on Enabling Technologies: Infrastructure for Collaborative Enterprises (WET ICE 2000)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2000-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128146530","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}

When tapping is detected, it alerts the network users on the danger of tapping. In designing the protocol, a model for an attacker is developed who sniffs the network and breaks down the proposed protocol, and the requirements on the protocol in terms of efficiency and security are defined. We also describe how to detect if a network interface card on a remote computer is in the sniffing mode. The proposed protocol employs cryptographic schemes to guarantee authentication of the code monitoring tapping operation and integrity of the data being sent. Finally, the proposed protocol can protect authorized users from illegal eavesdropping on the network.","PeriodicalId":435283,"journal":{"name":"Proceedings IEEE 9th International Workshops on Enabling Technologies: Infrastructure for Collaborative Enterprises (WET ICE 2000)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2000-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114386221","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}

These include communication, coordination, planning, monitoring, assistance, and protection. The framework also includes three general measures of these mechanics: effectiveness, efficiency, and satisfaction. The underlying idea of the framework is that some usability problems in groupware systems are not inherently tied to the social context in which the system is used but rather are a result of poor support for the basic activities of collaborative work in shared spaces. We believe that existing low-cost evaluation methods-heuristic evaluation, walkthroughs, user observations and questionnaires-can be modified to include this framework in a way that helps a groupware evaluator uncover these usability problems.","PeriodicalId":435283,"journal":{"name":"Proceedings IEEE 9th International Workshops on Enabling Technologies: Infrastructure for Collaborative Enterprises (WET ICE 2000)","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2000-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132587055","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}

A collaboration is described between human factors and technological researchers based on observations of prototypes in use in a real-world educational situation. The aim of the research is to develop a framework of design factors for the use of virtual actors in CVEs and to inform the development of the underlying CVE technology. The methodological approach followed involves the development of prototype virtual learning environments in a series of distinct phases of increasing sophistication. The environments are based on an ancient Egyptian game (Senet) and are aimed at children at Key Stage Level 2 of the National Curriculum for education in England. The paper shows how established 2D multimedia technologies were used to develop robust prototypes which were then observed in use by children. Results from these phases have been used to guide the current phase of work. This involves the construction of a 3D shared virtual environment using the experimental Deva virtual reality system.","PeriodicalId":435283,"journal":{"name":"Proceedings IEEE 9th International Workshops on Enabling Technologies: Infrastructure for Collaborative Enterprises (WET ICE 2000)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2000-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115730519","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}
