Watermarking using pixel-wise masking in the wavelet domain proves to be quite robust against common signal processing attacks. Initially, in a system proposed by Barni et al., embedding is made only in the highest resolution level; there are two disadvantages to this technique: the watermark information can be easily erased by a potential attacker and embedding in the DWT is susceptible to geometric attacks, such as shifting. To enhance this watermarking method, we use a modified perceptual… CONTINUE READING
