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.
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.
