A Novel Watermarking Algorithm Based on Phase Congruency Corner Detection and SVD

In order to protect the copyright of digital productions, a novel watermarking algorithm based on phase congruency corner detection and Singular Value Decomposition (SVD) is presented. By introducing the phase congruency detects corners and edges method, the attacked watermarked image can be corrected and the watermark synchronization is realized. In this way, which are used for information hiding, can be correctly detected even after signal processing and geometric attacks. The characteristic of U matrix in the result of SVD is finally applied for watermark embedding. The application of the proposed method makes the watermark capable of transparent hiding. Simulation results show that our method proved to be extremely robust against different attacks.
