“…In literature, the usage of P2P network with DRM has been already addressed to store protected objects [1,7]. [7] has described a P2P network for content distribution where the DRM protected content can be distributed.…”

“…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.…”

“…This allows stressing the points where a DRM solution can be adapted to exploit the P2P capabilities, so as to reduce the complexity and costs of the DRM service, considering scenarios related to the user verification and grant authorization from licenses. & Section 4 presents the details regarding the insertion of the DHT P2P into the DRM solutions for managing the grant authorizations, and not for managing content as in [7], and [1,3]. The proposed solution is general enough to be adopted in other DRM solutions since the information stored into the P2P refers to the grant authorization and to the certification of device which are suitable for almost all DRM solutions.…”

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.

“…Comprehensive review of the multimedia standards is given in (Stanchev 2009, Allasia andGallo 2009). For instance, the adoption of MPEG-7 ("MPEG-7") suggests description of metadata related to digital items, while MPEG-21 ("MPEG-21") helps in describing metadata related to a governed content.…”
