New pending patent applications are published on Thursdays by the USPTO. Both of today's Spotlight Applications concern aspects of digital rights management. Assigned to Apple, the first application discloses techniques for securing user data with DRM keys. Assigned to BrowsePlay, the second application discloses techniques for secure cross-platform video transmission.
20170222992, "Method for Securing user data with DRM keys," assigned to Apple.
Some embodiments provide convenient auto-authentication for user data on a primary device, while still providing a significant level of security, by taking advantage of existing security and cryptographic measures used to communicate with a secondary device. The primary device of some embodiments encrypts the user data on the primary device using a cryptographic key based on a set of keys received from the secondary device. In some embodiments, the primary device encrypts authentication data, or a local key generated from the authentication data, using a remote key received from the secondary device, and encrypts the user data with the local key. In some embodiments, the keys received from the secondary device are an existing set of keys for establishing an encrypted channel of communication for transmitting digital rights management (DRM) protected content according to a DRM protection scheme.
20170223423, "System and method for secure cross-platform video transmission," assigned to BrowsePlay, Inc.
A system and method for transmitting video over a network, e.g., the Internet, securely without the need of third-party video players or plugins. The system and method may be particularly useful for mobile web applications. The system and method may provide mechanisms that authenticate and authorize users of video, tracks usage and distribution, and enables high quality video to be delivered instantly in all popular browsers, making it a truly cross platform distribution system. By freeing video as an element from the restrictions of the <video> tag, video can be displayed and manipulated as images are currently while maintaining digital rights management (DRM) security. Website backgrounds and other major design elements may be rendered in video that can be marked up, written onto, and potentially deep-linked to links to the products by multiple techniques.
