摘要

Joint access to shared resources (e.g., objects, applications, and services) among autonomous domains that form a coalition has recently become important in Computer Supported Cooperative Work (CSCW) system. The brass tacks in coalition are that these domains have different self-interests although they focus on achieving a common goal. In this paper, to enable effective protection of jointly-owned resources and prevent the right abuse, a domain-role-based access control model based on basis of the traditional RBAC model is proposed. The domain in this model has been express a group data and a group operations to every data in group, deferent domain's access right is deferent to same data, that fulfil the control right demand of deferent space to data. By role dynamic connecting to domain, indirect defining the access right of user to data, predigesting right management, avoiding direct authorization and cancellation between user and data. In addition, DRBAC model's access control information express method and how to apply this model has been presented, and introduce a instance system based on this model.
