Abstract:
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.
