Secure Access Control Model for Business Process

In this paper, we research the secure management of business process, and propose a access control model which could authorize the data object. Based on the model, a role analysis algorithm that could support the dynamic assign of task is given. The algorithm considers different instance environment of business process, and supports dynamic assign of tasks, which could improve the adaptability and flexibility of workflow. Then combining the workflow management with life cycle management, we propose the life cycle business process model, and discuss its access control strategy.
