Nathalie H. Duroseau,Robyn R. Millerembedder simply follows point-by-point constraints given by the perceptual mask. Experimental results supporting our analyses are also shown, with examples of watermarking in the spatial domain as well as the DCT domain.

In experimental results, PSNR is about 6dB~15dB higher in the first method and BER is about 1/5~1/2 times lower in the second method than conventional patchwork.

Mathematical analyses and experiment results consistently verify the effectiveness of the content-dependent watermarking scheme. To our knowledge, this anti-disclosure watermarking is the first work that takes resistance to both collusion and copy attacks into consideration.

Kirk A. B. Newring,Megan N. Carternst the attacks produced by Stirmark, such as cropping, filtering, image compression, rotation, scaling. It also has a good robustness against combination of several kinds of attacks. It is indicated that this new intelligent decoder has superior advantages over the existing ones in many aspects.
