In this chapter, the authors propose the expression and the modelling of the most important principles of privacy. They deduce the relevant privacy requirements that should be integrated in existing security policy models, such as RBAC models. They suggest the application of a unique model for both access control and privacy requirements. Thus, an access control model is to be enriched with new access constraints and parameters, namely the privacy contexts, which should implement the consent and the notification concepts. For this purpose, the authors introduce the Privacy-aware Organisation role Based Access Control (PrivOrBAC) model.
