Abstract: Watermarking technology insert ownership information in suitable form inside any media like audio, video, image etc, so that owner of the object will claim his/her ownership when anyone claims his/her false ownership on that object. Proposed work, proposes a new algorithm for watermark insertion and extraction named as “Non Blind DWT Based Multiplicative SVD Watermarking algorithm†which is new version of the algorithm proposed by Bhargava [8] in his paper “Digital Image Authentication System Based on Digital Watermarking†.In this paper he is utilizing additive approach for watermark embedding and extraction algorithm and proposed algorithm utilize the multiplicative approach also he embeds watermark in one sub-band i.e. approximation sub-band and proposed algorithm utilize all four sub-bands for watermark embedding.
