Description
Summary:This paper proposes a semi-fragile watermarking algorithm resisting to RST (Rotation, Scaling, Translation). The algorithm can be used to verify the authenticity and integrity of image content. Firstly, the algorithm generates watermarking information by using the edge of the scaled image, and embeds watermarking information based on human visual system. Before detecting watermarking, the parameters of geometric distortions are estimated and restored by using the original moment information. Finally, users compare the extracted watermarking information with the reconstructed watermarking information of the watermarked image to achieve authentication. The experiment results show that the watermarking algorithm has the immunity to common operation (Compression, Noise, Filtering, RST, and so on). The watermarking algorithm can also achieve accurate authentication and tampering localization to malicious processing (Cropping, Replacing).
