Gerência de Direitos de Acesso de Usuário em Ambientes Virtuais Colaborativos

José Valentim dos S. FilhoAloysio de C. P. PedrozaJean-Pierre Courtiat

CVEs (Collaborative Virtual Environments) represent an important category of CSCW (Computer- Supported Cooperative Work) systems that generally make use of a 3D shared space in order to provide collaboration facilities. With respect to polices access control in the CVEs, they are often only rolebased. In this paper, we propose a CVE with an adaptive access control. The access level of a user on each object depends of the user and object's state. Moreover, we have defined an API ( Application Program Interface) to makes possible the CVE integration with other collaborative applications.
