Abstract :
In this paper, the authors propose a new procedure for copyright protection by using a bio-inspired wavelet based data hiding approach. The proposed method takes advantage of human visual system (HVS) characteristics to provide better watermarked image quality. It also exploits visual secret sharing (VSS) technique to guarantee the security of the procedure. Performance improvement with respect to the existing algorithms is obtained by particle swarm optimization (PSO).
