An improved hybrid image watermarking scheme in shearlet and wavelet domain

Watermarking is one of the best solutions for copyright protection and authentication of multimedia contents. In this paper a hybrid scheme is proposed using wavelet and shearlet transforms with singular value decomposition. For better security, Arnold map is used for encryption. Examining the results and comparing with other methods show that this hybrid proposed scheme with simultaneous utilization of wavelet and shearlet is able to be robust against a wide range of geometrical and image processing attacks as well as providing transparency.
