New patents are issued on Tuesdays. Both of today's Spotlight Patents concern aspects of digital rights management. Assigned to Seagate, the first patent addresses security threshold enforcement in anchor point-based digital rights management. Assigned to Toshiba (JP), the second patent addresses a semiconductor device with copyright protection function.
9,043,603, "Security threshold enforcement in anchor point-based digital rights management," assigned to Seagate.
Digital rights management (DRM) can be effectively implemented through use of an anchor point and binding records within a user's anchor point domain. Assigning security levels to various components within an anchor point based DRM system and evaluating them against a security criterion provides additional protection against authorized access of the digital content. The content provider may specify the security criterion (e.g., a security level threshold), and the ability to use the digital content is denied or granted based on the ability of components to satisfy this criterion. For example, the ability to use a digital property instance is granted to a content handler that satisfies the security criterion and denied to a content handle that does not satisfy the security criterion.
9,037,874, "Semiconductor device with copyright protection function," assigned to Toshiba (JP).
A semiconductor device includes a serial communication interface connector, a non-volatile semiconductor memory, a memory controller, and a memory reader/writer. The serial communication interface connector is capable of being connected to a serial communication interface terminal of electronic equipment. The memory controller includes a memory interface connected to the non-volatile semiconductor memory and a copyright protection function and controls the non-volatile semiconductor memory. The memory reader/writer includes a controller interface connected to the memory controller and a serial communication interface connected to the serial communication
