New patents are issued by the PTO on Tuesdays. Both of today's Spotlight Patents concern aspects of digital fingerprinting. Assigned to Terbium Labs, the first patent addresses techniques for detecting copied computer code using fingerprints. Assigned to Gracenote, the second patent addresses techniques for authorizing devices based on identifying content distributor.
8,997,256, "Systems and methods for detecting copied computer code using fingerprints," assigned to Terbium Labs LLC
Systems and methods of detecting copying of computer code or portions of computer code involve generating unique fingerprints from compiled computer binaries. The unique fingerprints are simplified representations of the compiled computer binaries and are compared with each other to identify similarities between the compiled computer binaries. Copying can be detected when there are sufficient similarities between at least portions of two compiled computer binaries.
8,997,164, "Authorizing devices based on identifying content distributor," assigned to Gracenote.
Methods and systems to authorize devices and/or perform other actions based on identifying content distributors are described. In some example embodiments, the methods and systems access video content playing at a client device, calculate fingerprints of a portion of the video content, identify a distributor of the video content based on the fingerprints, and perform an action in response to the identification of the distributor of the video content, such as actions to authorize the client device or other associated devices (e.g., second screens) to receive content from the distributor, actions to present sponsored content to the client device or associated devices, and so on.
