....against D A conversions (e.g. printing) Algorithm performance must permit embedding in real time Blind detection schemes must be used Visibility of the watermark should be low to imperceptible. Adversaries are not expected to mount even moderately elaborate attacks such as StirMark [11], collusion attacks [2] or copy attacks [9] in this industrial setting. This is due to the following assumptions: The attacker does not have full control over the working environment. This implies that he will not necessarily have the tools required to conduct the abovementioned attacks at his ....

.... current) work in watermarking has been applied, with robustness and imperceptibility evaluated experimentally [32] Many attacks consist of additive noise, compression (e.g. MP3 for audio, JPEG for images, and MPEG 2 for video) or geometric transformations such as rotation, shifting, and scaling [35]. Recently, more theoretical approaches have attempted to provide watermarking, and the larger field of information hiding, with a stronger foundation [44, 16, 27, 47, 10, 33, 51, 31, 34, 8, 48] Of particular note, Moulin and O Sullivan [34] have introduced a powerful information theoretic ....

Rotation: In Stirmark attack [6], the watermarked image is rotated by small angles (up to 5 # ) to remove the correlation with the pseudo noise sequence used for extraction. A block based sliding correlator used before extraction can detect the rotation and it can be compensated. Table 2 shows that the watermark could still be ....
