Abstract
Privacy has been acknowledged to be a critical requirement for many business (and non-business) environments. Therefore, the definition of an expressive and easy-to-use privacy related access control model, based on which privacy policies can be specified, is crucial. In this work we introduce a family of models (P-RBAC) that extend the well known RBAC model in order to provide full support for expressing highly complex privacy-related policies, taking into account features like purposes and obligations. We also compare our work with access control and privacy policy frameworks such as P3P, EPAL, and XACML.
