Abstract

In this paper, a new counter-geometric attack watermarking scheme is proposed, which uses the matching of corner points that are extracted by Harris corner detector. In the process of watermark embedding, the watermark is adaptively embedded according to the HVS. In the detection process, a new matching method implements the coarse matching of the corner points and random sample consensus is used to refine the matching of the corner points. And then the parameter of affine transform is precisely estimated by the matching of corner points. Therefore, the watermark is detected based on the register of the geometrical-attack watermarked image. The experimental results are shown that this proposed scheme can not only counter geometrical attacks and signal processing but also improve the capacity of watermark embedding.
