New pending patent applications are published by the PTO on Thursdays. Both of today's Spotlight Applications concern aspects of digital rights management. Apparently assigned to Intel, the first application discloses techniques for distributing digital rights management digital content in a controlled network ensuring digital rights. Assigned to Fasoo (KR), the second application discloses techniques for managing digital copyright on ePub-based content, and for providing ePub-based content according to user's right.
20150039516, "System and method for distributing digital rights management digital content in a controlled network ensuring digital rights," apparently assigned to Intel.
A system and method for managing digital rights. The method includes receiving a Universal Resource Identifier (URI). The URI is used to identify a location for a user selected digital media item. The digital media item is to be played in a local area network (LAN). The selected digital media item is retrieved from a content server over a network connection. If the selected digital media item is encrypted, a license to decrypt the selected media item is obtained. Access to the license is based on a plurality of access rules. The plurality of access rules are based on the terms of the license. The plurality of access rules may also include personal owner rules. If a request for the license adheres to the access rules, the license is received via a secure out of band transfer and the selected digital media item is decrypted for playback via one or more media rendering devices.
20150026456, "Apparatus and method for managing digital copyright on ePub-based content, and apparatus and method for providing ePub-based content according to user's right," assigned to Fasoo (KR).
Disclosed are an apparatus and method for managing a digital copyright on electronic publication (EPUB)-based content and an apparatus and method for providing EPUB-based content according to a user's right. An encryption unit of the apparatus for managing digital copyright generates encrypted unit files by encrypting a plurality of unit files included in content in the form of a compressed archive including the plurality of unit files with different encryption keys, stores the encrypted unit files in a content database, generates mapping data by mapping the encryption keys to pieces of identification information of the encrypted unit files, and stores the mapping data in an encryption key database. A rights management unit transmits an encryption key selected from among the plurality of encryption keys to a content provision apparatus, which decrypts the encrypted unit files and provides the unit files to a user, based on at least one of identification information of the user and identification information of the content included in an encryption key provision request message received from the content provision apparatus.
