When I was at university, I did some stuff on digital watermarking (this was
about 8 years ago, mind).
You could take a still image, put a hidden watermark on it (and it was
hidden, we did difference mattes and still couldn't isolate it) and
basically tried to break it. by the time we'd broken it, it was severely
degraded compared to the original.
What interests me about all this is where the responsibility lies. Is it
really down to the theatres to police people bringing video cameras? I don't
see anyone complaining about people pointing camcorders at a DVD playing on
a home TV...
