Social Access Control

Facebook is one of the most important social networking sites used by over a billion of people. Facebook offers a specialized and rather limited approach to decide upon content privacy for it's users. In this paper we analyze the content protection features Facebook offers. We suggest four classes of Facebook users ranging from consumers with very limited content privacy requirements to consumers interested in fine-granular content restrictions. We want to empower the customer to choose on the access control model meeting their specific requirements. The access control model shall be customer-based and not modeled on a general Facebook-wide level. We show how such a flexible approach can be introduced into Facebook by the usage of the Access Definition and Query Language.
