Abstract
Digital watermarking has emerged as a potential solution to copyright-related issues of digital data. A novel, highly secure robust digital watermarking method using DWT-SVD is presented in this paper. Instead of using the conventional watermark embedding process where the watermark gets embedded over the entire host image, the coefficients for embedding the watermark inside the host image has been identified in this proposed method. Such selection of pixels used for insertion of watermark makes this algorithm highly secure, robust, and imperceptible. The experimental results demonstrate the efficiency of the proposed method in aspects of high robustness and good imperceptibility.
