On the basis of traditional RBAC, TBAC and security workflow model, the authors propose a Role and Task-Based Access Control model (RTBAC), whose architecture is not user-role-permission but user-role-task-permission, and which adds periodic time and task weight constraint mechanism. The basic concepts of RTBAC and formalization description are introduced and analyzed; moreover the mapping from the BPEL-based process to RTBAC was implemented in this paper.
