Right Management Infrastructure for Home Content

Users are creating and sharing their own content. Based on various properties, user groups are created, which may need to share content only between members. This induces the need for a rights management solution, which keeps the user and his content in focus. Such a solution will enable fine grained rights control over distributed material in an easy and secure way. In order to make the life of the user easier, devices in the home network and in personal area networks may form a device domain, which can be managed as one entity. To manage such a device domain and to have it tamper resistant, an always online device would be the best focal point. An entity called Digital Rights Management (DRM) broker is introduced to serve as a home agent, cache for user right definitions and to act as a gateway for external access of home content. This node provides connection interface between the various DRM standards used by external content provider companies. The possiblity of user-centric content sharing with the help of a home DRM architecture is shown. In this paper, a solution is shown for efficient device domain management, a tamper resistant central unit is recommended and a service example is shown.
