  • Digital watermark systems and methods
    Patent number: 8364966
    Abstract: A digital watermark is added to audio or visual content. An illustrative embodiment permutes the content, alters the permuted content to encode a watermark, and inverse-permutes the content to return same to substantially its original form. Related watermark decoding methods are also detailed, as are ancillary features and techniques.
    Type: Grant
    Filed: October 23, 2007
    Date of Patent: January 29, 2013
    Assignee: Digimarc Corporation
    Inventors: Andrew Johnson, Michael Biggar
  • Digital watermark systems and methods
    Patent number: 8037311
    Abstract: A digital watermark is added to audio or visual content. An illustrative embodiment segments the content, permutes the segments, and transforms such data into another domain. The transformed data is altered slightly to encode a watermark. The altered data can then be inverse-transformed, and inverse-permuted, to return same to substantially its original form. Related watermark decoding methods are also detailed, as are ancillary features and techniques.
    Type: Grant
