Abstract: On the basis of studying the existing RBAC models in the literatures published, this paper put forward an improved model (MRRBAC model), and gave its formal definition, and designed and implemented it. The MRRBAC model could realize finegrained access control permission on the operations and objects, set the different roles of different functional operation via automatic configuration interface. Practice indicates that MRRBAC model improves the security of the system and the flexibility of configuration.

Key words: RBAC, control strategy, personalized operation, finegrained access control, information system
