Abstract

The patchwork watermarking scheme is investigated in this chapter. The performance of this algorithm in terms of imperceptibility, robustness and security has been shown to be satisfactory. Robustness of the patchwork algorithm to the curve-fitting attack and blind multiple-embedding attack is presented also in this chapter. Robustness against jitter attack which is a natural enemy of this watermarking al-gorithm is also studied.
