You're asking for perfect DRM here. Without that, such a stamp would be trivial to remove. The creation of a perfect (and completely general) DRM scheme is an exercise for the reader. It is perhaps easier to prove that such a perfect and completely general DRM scheme is unworkable where end users have access to a universal copying and processing system.
