....However, PSC compliant watermarks cannot be defeated by the Wiener attack. Watermarks that are close to being PSC compliant also resist attack well, so in practice, simple parametric models for the watermark power spectrum may be sufficient. These results support the heuristic arguments [2] 3] [24], 25] in favor of matching a watermark to the spectral content of the signal being watermarked. They also refute earlier arguments that advocate bandpass, highpass, or white watermarks. We remark that compression algorithms like JPEG and MPEG tend to preserve only the large magnitude frequency ....

....of private and semi private marking seem to be evidence in court to prove ownership and copy control in applications such as DVD where the reader needs to know whether it is allowed to play the content or not. Many of the currently proposed schemes fall in this category [18] 19] 20] 21] [22], 23] 24] Public marking (also referred to as blind marking) remains the most challenging problem since it requires neither the secret original I nor the embedded mark M.In deed such systems really extract n bits of information (the mark) from the marked image: I # K # M [25] 26] ....
