New pending patent applications are published by the PTO on Thursdays. Both of today's Spotlight Applications concern aspects of digital rights management. Assigned to Intel [Imtel in the published app; typo probably], the first application discloses techniques using storage devices to implement digital rights management protection. Assigned to Western Digital, the second application discloses technqques for accessing content from an intelligent storage.
20130276146, "Method and apparatus to using storage devices to implement digital rights management protection," assigned to Intel.
Embodiments of systems, apparatuses, and methods to securely download digital rights managed content with a client are described. In some embodiments, a system establishes a secure root of trust for the client. In addition, the system establishes a secure tunnel between an agent of the client and a storage system of the client. Furthermore, the system securely downloads the digital rights managed content to the storage system via the secure tunnel and securely provides the digital rights managed content from the storage system to a display.
20130268771, "Digital rights management system and methods for accessing content from an intelligent storage," assigned to Western Digital.
The present invention relates to accessing content stored on a storage device and protecting the content with a digital rights management (DRM) scheme. The storage device may be a disk drive, or network attached storage. The storage device can perform cryptographic operations and provide a hardware root of trust. The DRM employs a binding key, a content key, and an access key. The binding key binds the content to the storage device and is based on a key concealed on the storage device. The binding key itself is not stored anywhere on the storage device. The content key is a key assigned to the content. The access key is determined based on a cryptographic combination of the content key and binding key. In one embodiment, the content is encrypted based on the access key and stored in encrypted form in the storage device.
