In this paper, we present an approach to instrument a Simple Protocol And RDF Query Language query rewriting algorithm enforcing privacy preferences. The term instrument is used to mean supplying appropriate constraints. We show how to design a real and effective instrumentation process of a rewriting algorithm using an existing privacy-aware access control model like PrivOrBAC. We take into account...
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...
