20110047389, "Trusted Infrastructure Support Systems, Methods and Techniques for Secure Electronic Commerce Electronic Transactions and Rights Management," assigned to Intertrust Technologies.
An integrated, modular array of administrative and support services are provided for electronic commerce and electronic rights and transaction management. These administrative and support services supply a secure foundation for conducting transaction-related capabilities over electronic networks, and can also be adapted to the specific needs of electronic commerce value chains. In one embodiment a Distributed Commerce Utility having a secure, programmable, distributed architecture provides these administrative and support services. The Distributed Commerce Utility may comprise a number of Commerce Utility Systems. These Commerce Utility Systems provide a web of infrastructure support available to, and reusable by, the entire electronic community and/or many of its participants. Different support functions can be collected together in hierarchical and/or networked relationships to suit various business models or other objectives. Modular support functions can be combined in different arrays to form different Commerce Utility Systems for different design implementations and purposes.
20110047080, "System and method for DRM content management," assigned to Samsung (KR).
A system for managing a Digital Rights Management (DRM) content includes a content providing server for providing an environment, through which a DRM content and a digital right of the DRM content can be registered, a service providing server for issuing a license serving as a usage authority for each of DRM content files provided from the content providing server, generating a license revocation execution value in a specific field of the issued license, encrypting the generated license revocation execution value for transmission to a user terminal, and the user terminal for inspecting the license of the DRM content file transmitted from the service providing server, and extracting and storing the license and the license revocation execution value to use a corresponding DRM content file according to the license, and upon receiving a revocation request, transmitting a revocation result of the corresponding license to the service providing server.
