Abstract: The rapid growth in usage of digital technologies brings tremendous interest to the field of digital authentication. Digital watermarking is one of the most powerful authentication techniques used to restrict unauthorized usage of copyrighted images. Unique logo can be inserted into different copies of the same digital image for different clients. This will curtail the illegal usage. Most of the earlier works used Redundant Discrete Wavelet (RDWT) transform in combination with SVD. These watermarking schemes suffered with false positive problem. Hence, in this work, a hybrid blind watermarking is developed by using a combination of Redundant Discrete Wavelet (RDWT) and Hadamard transform to get rid of false positive problem and to produce imperceptible, robust and secure watermarking scheme.
Keywords: Redundant Discrete wavelet transform, slant transform, PSNR, NCC.
