Privacy is a vital requirement for all the organizations. Specifying the privacy policy is crucial problem in Role Based Access Control (RBAC) model. Conflict resolution is another important issue in permission assignment in the Privacy Aware Role Based Access Control (P-RBAC) model. It is proved that there is no conflict up to two permission assignments, but there is a conflict when three or more permission assignments are considered together. To overcome this issue and to improve the efficiency of the system, in this paper the authors propose a multiple conflict detection algorithm and implemented it for detecting conflicts in three or more permission assignments and redundant permission assignments are reduced in the P-RBAC model.
