The two watermark versions of each block are embedded into the less significant bit planes of the different blocks based on the secret key, respectively. They not only can

So in this paper, we present three novel data hiding algorithms based on incremental updates which can provide large enough embedding capacity without any change of file display. These algorithms embed information by different covert channels and the logi

Henrik Schultz,Hubertus von Dresslerrmark pattern is designed that is sensitive to image processing specific to illegal copying. This is done on the basis of the aliasing effect, which causes image distortion when the re-sampling frequency is low. Watermarks using such patterns are embedded in the original video. They become visible o

When these shares are physically superimposed, the secret can be instantly observed. A known problem is that of authentication. How is it possible to know that the secret being recovere
