A task-role-based access control model, called the TR-EDRM(Task-role expended digital rights management model), is proposed to meet the demand of modern enterprise application. The model is based on the task classification. It adopts task-and-role-combined approach and solves the problem of role hierarchy partial inheritance. The model can be applied to workflow and non-workflow tasks. The security, flexibility and transparence of enterprise digital content management can be improved as a result.
