Abstract

In this paper, A Hybrid Digital Image Watermarking method using IWT and SVD is presented which can be used for copyright protection through owner identification. The watermark pixel values are directly embedded into the singular values of 1-level IWT decomposed sub-bands. Digital signature based authentication mechanism is used to solve the false positive problem faced by most of the SVD-based watermarking methods. The digital signature mechanism consists of signature generation, embedding after embedding the watermark and extraction. The ownership is then authenticated before extraction of watermarks. Hence the scheme attains security. The experimental results reveal the superiority of the proposed method in terms of imperceptibility, robustness and capacity due to the properties of IWT and SVD. To verify the feasibility of the proposed scheme, MATLAB simulation is used.
