Access control comprises different kinds of access control policies. This paper proposed an RBAC-based access control integration framework to achieve and manage various access control policies during legacy system integration. Permission is defined as tasks, and tasks are extracted and organized as tree structure for each system. Then, a global task tree and an integrated policy library are generated for the integrated system to reorganize access control policies of different legacy systems. Additionally rules for authorization management are given to carry out further authorization. A case study is demonstrated to depict the proposed framework is a feasible and flexible solution for access control integration.
