Abstract: TBACEABWF is proposed for the need of dynamic and realtime safe management of workflow in the examination and approval of business. Different from traditional model，this model carried out the synchronization of authorization flow of access control with workflow, meeting the request of taskbased Access Control of examination and approval of business workflow. By introducing time concept, the authorization of access control is related with time, thus satisfing the time efficiency request of task in the examination and approval of business workflow. By introducing the rule of script to normalize control logic, the model is provided with the dynamic adjustability, which supports the two characteristics of examination and approval of business workflow, namely certainty and uncertainty.

Key words: workflow, TBAC , examination and approval of business
