Abstract :
When specifying privacy preferences, the data owner can control who may access its personal data, for which purpose and under which accuracy. In this paper we present an approach that enforces the privacy policy preferences by query transformation. We present also how to instrument this rewriting query algorithm using a privacy-aware model like PrivOrBAC. We take into account various dimensions of privacy preferences through the concepts of consent, accuracy, purpose and recipient.
