Abstract
Watermark robustness and imperceptibility often are contradiction,in order to trade off them, this paper presents a new adaptive robust watermarking algorithm.A DCT domain masking of original image is generated with the properties of human visual system,combining with its value to adjust a pair of the 8×8 DCT block intermediate frequency coefficient's relationship to embed the watermark adaptively.When watermarking is extracted, the Zernike moment method is used for geometric correction to resist geometric attacks .The experimental results show that the algorithm solves the contradiction between watermark robustness and invisibility and has good robustness resistance geometric attack and common malicious attacks.关键词
