One of the shortcomings of the Role-Based Access Control model (RBAC), used in Workflow Management Systems (WfMS), is that it cannot grant permissions to users dynamically while business processes are being executed., We propose a Take-Oriented Access Control (TOAC) model based on RBAC to remedy this problem. In TOAC, permissions are associated with tasks as well as roles. Users can get permissions through tasks that they carry out in certain processes. And when they are out of processes, permissions can be granted by the roles that they are associated with. Moreover, to facilitate delegation in WfMS, we present a task delegation model which is aim at TOAC.
