    Abstract

    The management of Web users' personal information is increasingly distributed across a broad array of applications and systems, including online social networks and cloudbased services. Users wish to share data using these systems, but avoiding the risks of unintended disclosures or unauthorized access by applications has become a major challenge. We propose a novel access control model that operates within a distributed data management framework based on datalog. Using this model, users can control access to data they own and control applications they run. They can conveniently specify access control policies providing flexible tuple-level control derived using provenance information. We present a formal specification of the model, an implementation built using an open-source distributed datalog engine, and an extensive experimental evaluation showing that the computational cost of access control is modest.
