“…The first 7 steps are exactly the same as those performed in the centralized AXMEDIS MPEG-21 DRM, while the other steps have been added to save the Enabling Code into the DHT. In the first steps, the PMS Client (in the client device/player) performs a SOAP call (2) to the PMS Server; the PMS Server performs the certification asking to the AXCS (3) and (4) and it gets the result (5); such result is transferred to the Client device (6), (7). In order to keep aligned the DHT, the key is requested from the AXCS DB (9), (10); encrypted (11) and passed to the DHT (12), (13), (14) and (15).…”

“…The solution presented in this paper complements the solution proposed in [7] which was limited to the exploitation of P2P for content sharing and distribution. In [1][2][3], the P2P network based on DHT has been used to index rights and metadata allowing users to search content integrated with licenses (the so called governed resources) by looking for specific license issuers, right grants or principals (right recipient user) in the P2P. This last case of iDRM [3], the proposed P2P solution presents unsolved complexities in the DRM management, since the verification and authentication activities are still performed by referring to a central server, without exploiting the P2P network.…”

Digital rights management solutions are today quite widespread. Their cost is still quite expensive, and thus in many cases, their application is limited to specific business cases. On the other hand, the market still offers large cases where scalable DRM solutions would find their applicability, for example the management of complex cross media content such as the one used for the educational content, for electronic medical record, etc. In this paper, the focus is on reducing DRM costs by solving scalability problems lying behind the complexity of granting authorizations and performing verification for a large number of users, content and rights associated with them. The proposed solution is based on the exploitation of the DHT P2P network and storage to cope with verification and grant authorization. The paper reports the structure of the DRM solutions, the details for including the DHT P2P into the DRM architecture. The paper also reports details on how the proposed P2P DRM solution can be integrated into traditional DRM solutions. The provided experimental results have proved the reduction of costs, the scalability against the aforementioned cases. The studies and solutions reported in this paper have been worked out and validated on top of MPEG-21/AXMEDIS DRM solutions and tools. On the other hand, the solution is general enough to be adapted in other DRM solutions.

Peer-to-Peer (P2P) systems are widely used for sharing digital items without structured metadata and in absence of any kind of digital rights management applied to the distributed contents. In this paper we propose the implementation of a prototype application that makes use of a structured P2P system enabling the indexing of complex metadata, used to express digital rights. In this way the media contents are exchanged and played according to the expressed grants. The creation and the consumption of the shared contents can be performed through any MPEG-21 REL compliant software and the application allows indexing and search for both governed and ungoverned contents. The information about the license can be included in the queries and the P2P network can be used to share governed contents (both free and with fee) in a legitimate way. In particular the proposed approach represents a suitable solution for indexing and querying rights complex structures on DHT based networks.
