Abstract

While many watermarking methods show good robustness against common signal processing operations, security of the watermarking schemes under intentional attack exploiting knowledge of the implementation has been widely neglected. In this paper, we demonstrate straightforward, targeted attacks for a number of quantization based watermarking methods and provide implementations. The attacks require only one watermarked image and retain the fidelity of the image. The watermarking methods discussed are therefore not suitable for copyright protection applications.
