New pending patent applications are published by the USPTO on Thursdays. Both of today's Spotlight Applications concern aspects of digital rights management. Assigned to Pulselocker, the first application discloses techniques for limiting access to data by process or computer function with stateless encryption. Assigned to IBM, the second application discloses techniques for detecting usage of copyrighted video content using object recognition.
20170357786, "Method and apparatus for limiting access to data by process or computer function with stateless encryption," assigned to Pulselocker, Inc.
Systems and methods related to DRM content usage mechanisms for both online and offline usage of content are disclosed, including systems providing secure access to data regardless of network state or connectivity state to the networked access control mechanism. An access control mechanism having a secondary offline access control mechanism is presented, further including multiple implementations for data encapsulation, as well as providing a method for writes to files and to the filesystem itself by externally created applications with no API or modification to their operation.
20170357875, "Detecting usage of copyrighted video content using object recognition," assigned to IBM.
Techniques detecting usage of copyrighted video content using object recognition are provided. In one example, a computer-implemented method comprises determining, by a system operatively coupled to a processor, digest information for a video, wherein the digest information comprises objects appearing in the video and respective times at which the objects appear in the video. The method further comprises comparing, by the system, the digest information with reference digest information for reference videos, wherein the reference digest information identifies reference objects appearing in the reference videos and respective reference times at which the reference objects appear in the reference videos. The method further comprises determining, by the system, whether the video comprises content included in one or more of the reference videos based on a degree of similarity between the digest information and reference digest information associated with one or more of the reference videos.
