Research of Digital Watermarking Algorithm in Wavelet Domain Based on Arnold Transformation and SVD

摘要：

　　In this paper,Amold transform and Singular Value Decomposition(SVD) are combined to be introduced into the research of wavelet domain digital watermarking algorithm.During experiment,we embed the watermark through modifying the singular value of low-frequency domain of host image with the scrambled watermark information.The simulation experiments show that the algorithm realizes the embedding and extraction of watermark smoothly.There is no visual difference between watermarked image and original host image can be found by naked eye,that means the invisibility of the algorithm is well; the watermark still can be extracted after several kinds of algorithm and geometric attacks,that means the robustness of the algorithm is acceptable.The research has a certain value in the digital copyright protection and security printing.
