For the Personal Reader framework we have worked out a mechanism for restricting the access to RDF stores in order to protect user profiles: We implement access control into the query layer by re-writing queries, which are sent to the RDF store, according to access control policies. In our first prototype we use Protune - the trust negotiation framework of REWERSE - which was developed by REWERSE working group I2. This allows us to specify precisely which type of RDF statements are allowed to access in which context.
