Tuesdays the PTO issues new patents. Both of this week's Spotlight Patents address aspects of digital fingerprinting. Assigned to Voible, the first patent concerns techniques for fingerprinting and identifying video objects. Assigned to Digimarc, the second patent concerns techniques for identifying audio or video content.
8,689,337, "Systems and methods of fingerprinting and identifying video objects," assigned to Vobile, Inc.
Systems and methods are provided for identifying a video object using digital fingerprints. The digital fingerprints are generated from information extracted from the video object including encoded video. The digital fingerprints can be calculated in a manner that permits identification of both the video object and operational characteristics of the video object based on matching calculated digital fingerprints with known fingerprints of known video objects. Systems and methods are described that allow a DVD to be uniquely identified and identify whether the DVD is original, copied or pirated. Systems and methods are described for computing digital fingerprints from strings of bits in which certain additional data is optionally embedded. Systems and methods are described that permit media players to access known signatures of known video objects maintained on one or more databases and to identify video objects presented for playing on the media player.
8,688,999, "Methods for identifying audio or video content," assigned to Digimarc.
Methods and systems for identifying audio and video entertainment content are provided. Certain shortcomings of fingerprint-based content identification can be redressed through use of human-reviewers in a first party's social networking site environment. Access to a copy of a possible fingerprint-based match of user uploaded content is provided to a second party via a queue of an online interface provided by the first party. In response to providing access to the copy of the user uploaded content, manual human assessment data is obtained from the second party through the online interface. The manual human assessment data indicating a result of a comparison of the copy of the user uploaded content and data associated with reference content by one or more human reviewer(s). The manual human assessment data is used in concluding that the reference content corresponds with the user uploaded content.
