Abstract: Aiming at the weak robustness to the geometric attacks of the public-key watermarking algorithm, a public-key watermarking algorithm based on image feature keypoints is proposed. The feature keypoints of image are extracted by Harris-Laplace algorithm, the watermarking in the DCT domain of the feature zone is embedded, so it can rest the RST attack.

Key words: public-key digital watermark, Harris-Laplace algorithm, DCT
