In this paper we describe a policy based authorisation infrastructure that a cloud provider can run as an infrastructure service for its users. It will protect the privacy of users' data by allowing the users to set their own privacy policies, and then enforcing them so that no unauthorised access is allowed to their data.
Policy based authorization: is the means by which a trusted cloud provider or online service provider (OSP) protects the privacy of users' data by allowing the user to set their own privacy policies, and then enforce them so that no unauthorized access is allowed REF .
