On Thursdays the USPTO publishes new patent applications. Both of today's Spotlight Applications concern aspects of DRM. The first application discloses techniques for validating protected intra-system interconnects for DRM, no assignee given. The second application discloses techniques for digital rights protection in BitTorrent-like P2P systems, assigned to George Mason University.
Embodiments for validating protected data paths for digital rights management of digital objects are disclosed. Some embodiments disclosed herein may comprise processes or apparatus for transferring data from one or more peripherals to one or more computers or digital data processing systems for the latter to process, store, and/or further transfer and/or for transferring data from the computers or digital data processing systems to the peripherals. Some embodiments disclosed herein may comprise processes or apparatus for interconnecting or communicating between two or more components connected to an interconnection medium a within a single computer or digital data processing system.
20090210697, "Digital Rights Protection in BitTorrent-like P2P Systems," assigned to George Mason University.
To leverage the efficiency and the scalability of BitTorrent (BT) systems for Internet content distribution, the present invention discloses enhancing BT peer-to-peer systems to enable digital rights management without infrastructure changes. The technique involves runtime re-encryption of each file piece, which may already be encrypted, before a peer uploads it to any other peer. To access the re-encrypted pieces, a tracker site generates decryption keys that are unique for each peer and for each file piece. While any user can take part in the content distribution, only legitimate users with the unique decryption keys can access the plaintext of the encrypted distributed content.
