Digital watermarking methods and apparatus for use with audio and video content
First Claim
1. A method of tracking audio or video content comprising:
- utilizing a processor or electronic processing circuitry, decoding a first forensic identifier in a digital watermark, the first forensic identifier being associated with a forensic database, the first digital watermark having previously been embedded in the audio or video content; and
utilizing a processor or electronic processing circuitry, decoding a second forensic identifier, the second forensic identifier being associated with a content user, the second forensic identifier being carried with the audio or video content,the first forensic identifier and the second forensic identifier were embedded in the audio or video content at remote embedding locations, andthe first forensic identifier is associated with information in a first server, and the second forensic identifier is associated with information in both the first server and in a second server that is remotely located with respect to the first server.

Abstract
The present invention relates generally to digital watermarking and other forms of content identification. One claim recites a method including: receiving audio or video content, the audio or video content comprising at least two digital watermark payload layers, a first watermark payload layer comprising a content identifier which uniquely identifies the content, and a second watermark payload layer comprising a distributor identifier which identifies a distributor or distribution channel associated with the content; utilizing a processor or electronic processing circuitry, embedding a third digital watermark payload layer in the audio or video content, said act of embedding transforms at least some data representing the audio or video content to embed the digital watermark payload, where each of the first watermark payload layer, the second watermark payload layer and the third digital watermark payload layer are embedded in the audio or video content with different watermark protocols. Of course, other claims and combinations are provided as well.
