A RBAC model considering the user reliability in workflow system

Role based access control (RBAC) is one of the most important access control model, in this paper we present a kind of role-based access control model for workflow systems, named RW_RBAC. Based on the traditional RBAC system, this article introduces the conception of user's reliability to control the role assignment in the workflow system. With the help of it, the system can choose the more appropriate user to do the task when there is more than one candidate.
