Abstract

We shall show that non-invertibility is a necessary but not sufficient condition in resolving ownership disputes. We then define quasi-invertible watermarking schemes, and, present analysis that links invertibility and quasi-invertibility to some classes of watermarking techniques with different properties (which may or may not require original versions in watermark decoding), as well as to the different classes of attacks we have developed.
