A Digital Watermarking based on Discrete Fractional Fourier Transformation DWT and SVD
In this paper, a novel Discrete Fractional Fourier (DFRFT) Transformation DWT and Singular Value Decomposition (SVD)-based digital watermarking algorithm is proposed. The hybrid approach has the advantages of one-way and non-symmetric properties of SVD transformation, and good time-frequency features in frequency domain. Furthermore, chaotic map is used to shuffle the watermark so as to improve the robustness. Experimental results demonstrate that the quality of the watermarked image is good both visually and in terms of PSNR. Furthermore, proposed approach is able to resistance against a variety of general image processing attacks.
