摘要：Privacy is the most important aspect required for all areas of applications. A lot of concentration isrequired while specifying such privacy policies. Conflict resolution in assigning permissions to the roles is the majorissue as per the Privacy aware Role Based Access Control Model (P-RBAC). There could be a possibility that there isno conflict for up to two permission assignments, but we may gets conflicts when three or more permissionassignments are considered together.In order to overcome this issue we have proposed an extended conflict detection algorithm that includes the newlyadded components such as temporal and spatial constraints in defining privacy policies. The multiple permissionassignment requests are checked by comparing the context variables . Thereby the efficiency of the conflict detectionalgorithm is improved.
