A temporarily-spatially constrained model based on TRBAC (Task-Role Based Access Control) is proposed in workflow system. Temporary and spatial Constraint is that user is not only constrained by temporality, but also constrained by spatiality when user executes the task. The model suggests that a property of security level should be increased in task. The newly increased property can make the workflow more safety and flexibility.
