....(c26) pinched; c27) rippled; c28) sheared; c29) smart blurred; c30) thresholded; c31) twirled. watermarked image can be used. For those oblivious watermarking methods robust to geometric attacks without referring to any prior information in recovering geometric effects, readers should refer [20], 26] 32] In what follows, we shall introduce some attacks of this sort. StirMark [28] is a very strong type of attack that defeats many existing watermarking techniques. Analysis of StirMark [28] has shown that it introduces unnoticeable quality loss in an image with some simple geometrical ....

....of such methods in commercial and on line applications due to the high computational complexity of the exhaustive approach. One way to overcome this problem is to divide the image into segments or cells, and to embed the watermark into each segment. This has been done by Rhoads [7] by Lin et al. [8] as well as by Voloshynovskiy et al. [9] A particular case of this approach to watermark generation is the periodical tiling of the same watermark. In fact the idea of repeating the same watermark has several advantages. First, it allows to resist against cropping. Secondly, exploiting the ....

In what follows, we shall introduce some attacks of this sort. StirMark [28] is a very strong type of attack that defeats many existing watermarking techniques.

Based on these 2 Partofthischapter represents jointwork with J. Bloom, M. Miller, I. Cox, M. Wu and Y. Lui [83]. 23 properties, we showseveral techniques for extracting invariants from the original and rescanned image, with potential applications in image watermarking and authentication. These invariants helped design the watermarking algorithm proposed in this chapter to survive print and scan process. ....
