This paper proposed a workflow authorization model based on RBAC. Different from traditional authorization models based on subject-object pattern, this model provides the notion of temporal permission which represents the fact that can only perform certain operation on a task for a certain time interval, this can not only ensure that only authorized users could execute a task but also ensure that the authorization flow is synchronized with workflow.
