GEOMETRIC ATTAСKS MODELING ON BASIS OF AFFINE TRANSFORMATION

The paper is concerned with the digital watermarking techniques that can solve the copyright protection problem by embedding owner information inside the image. In particular the problems with modeling geometric attacks on basis of affine transformation are considered. It is noted that the goal of the geometric attacks, such as shifting, scaling, rotation, is to force the decoder to fail.

Keywords: digital watermarking, geometric attacks, affine transformation.
