Synchronous Counterfeiting Attacks on self-embedding Watermarking Schemes

Vol. 6  No. 1  pp. 251~257


This paper points out secure holes of the self-embedding watermarking schemes. To further illustrate their insecurity, this paper proposes a novel synchronous counterfeiting (SC) attack on self-embedding watermarking schemes. Some experimental results show that the proposed SC attack can not only forge watermark in any un-watermarked image and change the size of watermarked image randomly; but it also generate the excellent quality of the counterfeit watermarked image by cropping and/or pasting watermarked images with image block as a unit.
