This sort of data could be used for marketing purposes but also for malicious deeds. This paper addresses this threat and establishes a DRM architecture which protects user privacy by the core of its design by adding a third trusted party and an appropriate communication protocol. The work was influenced by a project in mobile DRM based on the OMA specification[1].enBeitrag
