  • Patent number: 8995711
    Abstract: Systems and methods are described for imperceptibly embedding information by identifying locations that can be imperceptibly modified, where the imperceptible modification by replacing original content using replacement content derived from elsewhere in the compressed bitstream to remove at least a portion of the original content, generating at least one piece of replacement data for each identified location, where overwriting a portion of the compressed bitstream with replacement data prevents a decoder from decoding original content due to decoding replacement content derived from elsewhere in the compressed bitstream, selecting pieces of replacement data using an embedding device, where overwriting portions of the compressed bitstream using pieces of replacement data encodes payload information in accordance with a predetermined coding scheme, and embedding the payload information in the compressed bitstream by using the embedding device to overwrite at least a portion of the compressed bitstream with the

  • Publication number: 20130097625
    Abstract: System and method for identification of ownership to media objects through analysis of semantic information in the media objects are disclosed Semantic information is a term that can be used to describe aspects of the content of a media object that are apparent to a human viewing or listening to the content One embodiment of the invention includes extracting semantic information from a specified media object, matching said semantic information of the specified media object against known semantic information of known media objects, and taking action based on the result of the companson.

  • Publication number: 20130054972
    Abstract: Systems and methods in accordance with embodiments of the invention enhance the security of content distribution using individualized playlists. In many embodiments, a playlist is individually composed for a client device so that the selection of content included in the playlist encodes information. One embodiment includes generating a watermark sequence, where each watermark sequence is a unique identifier, selecting between alternative chunks of encoded content based upon the watermark sequence, where each of the alternative chunks of encoded content includes the same perceptual content and differs in the way it is watermarked, and listing the selected chunks in a playlist, where content assembled using the playlist includes a unique watermark sequence.

  • Publication number: 20110129116
    Abstract: Systems and methods are described for imperceptibly embedding information by overwriting original video content with other content from a bitstream In a number of embodiments, the replacement of original content is efficiently implemented by referencing other information in the bitstream, also called reference content. One embodiment of the invention includes analyzing the compressed bitstream using a preprocessor to identify locations that can be imperceptibly modified, generating at least one piece of replacement data for each identified location using the pre-processor, selecting pieces of replacement data using an embedding device, and embedding the payload information in the compressed bitstream by using the embedding device to overwrite at least a portion of the compressed bitstream with the selected replacement data.
