Abstract :
We present an asymmetric watermarking method for copyright protection that uses different matrix operations to embed and extract a watermark. It allows for the public release of all information, except the secret key. We investigate the conditions for a high detection probability, a low false positive probability, and the possibility of unauthorized users successfully hacking into our system. The robustness of our method is demonstrated by the simulation of various attacks.
