Abstract
Client identifier watermarks in media signals are disclosed. An example apparatus to watermark a multilayered file includes a watermark storage to store media identifiers. The example apparatus also includes an encoder to encode a first bit sequence in the media file on a first encoding layer of a multilayered watermark, the first bit sequence to include a client identifier of a client associated with the media file, and encode a second bit sequence in the media file on a second encoding layer of the multilayered watermark, the second bit sequence to include a media identifier to identify media corresponding to the media file.
Claims20
An apparatus to watermark a media file, the apparatus comprising:
- a watermark storage to store media identifiers;
- and
- an encoder to:
- encode a first bit sequence in the media file on a first encoding layer of a multilayered watermark, the first bit sequence to include a client identifier of a client associated with the media file, and
- encode a second bit sequence in the media file on a second encoding layer of the multilayered watermark, the second bit sequence to include a media identifier to identify media corresponding to the media file.
A method of watermarking a media file for later identification of at least portions thereof, the method comprising:
- encoding, by executing instructions with at least one processor, a first bit sequence in the media file on a first encoding layer of a multilayered watermark, the first bit sequence to include a client identifier of a client associated with the media file;
- and
- encoding, by executing instructions with the at least one processor, a second bit sequence in the media file on a second encoding layer of the multilayered watermark, the second bit sequence to include a media identifier to identify media corresponding to the media file.
A non-transitory computer readable medium comprising instructions, which when executed, cause a processor to at least:
- encode a first bit sequence in a media file on a first encoding layer of a multilayered watermark, the first bit sequence to include a client identifier of a client associated with the media file;
- and
- encode a second bit sequence in the media file on a second encoding layer of the multilayered watermark, the second bit sequence to include a media identifier to identify media corresponding to the media file.
