The watermarking of digital image, audio, video and multimedia products in general have been proposed for resolving copyright ownership and verifying boldness of content. This paper studies the contribution of watermarking for developing the protection scheme. Wolfgang and Delp Algorithm (Technique) is used in case of watermark Embedding. The algorithm proposed the scheme of watermarking by encrypting the watermark images using symmetric encryption like DES. According to the method, the watermark symbol to be encrypted first using DES and then embedding it into RGB vectors of original image using SVD transformation sampling. The experiment justifies that the algorithm of embedding watermark has better robustness to JPEG compression attack. Piper diagram is ploted by the aquaChem 2011.1 software.
