In the case of audio watermarking, in the schema I am familiar with
the data is encoded in the spectral dimension. A simple 'binary diff'
would not work. AMOF, a binary diff wouldn't work to identify the
similarity between two different mp3 encodings of the same song. It
has been proven however, that any watermark can be stripped from a
file, but *not* necessarily detected. I would imagine that if the
recording industry chooses to invest sufficiently in watermarking,
they would not do so without at least a minimum of legal support
(criminalizing the removal of the watermark).
