Have you ever signed a file with GNUPG?
That's a watermark. Have
you ever used an SHA or MD5 signature of a file, and verified those
signatures with GNUPG?
What is the relationship?
These are not watermarks. The above are methods to prove or disprove
that any given person was the source of a given message. A watermark is
a means of marking a resource such that it may not be used by anybody
else without degradation of quality.
Wrong. Just means one can't claim it as your own without the original
author (and presumably other people) being able to verify who created
the original image/audio file.
Linux does not need an audio watermark, the whole
point of linux is about
the benefits of sharing.
If you want to have a way of restricting distribution of audio then perhaps
go fish in some other seas.
