The data which involves sound, image and video was kept in numeral system. Audiovisual data is digital form propositions several benefits and different abilities for normal user. Likely the most common used potential of digital media is the untroubled copy without degradation of the medium. Watermark have numerical environment, combination documents and it will copied, altered, distorted, and dispersed precise simply. For that, it is necessary to improve the structure for patent safety, defense against duplication, and validation of documents. Hence, digital watermarking is best solution for providing more security to client/server. In open communication channel during the transaction process. Now, in some existing methods only provide security against some normal attacks like Gaussian attack, jpeg attack, salt and pepper attack, etc. But it is not against RST invariant attacks. RST invariant Watermarking approach using DWT-SVD into block manner with Pseudo Zernike moment, Surf feature and Affine transform give batter recovery on watermark image after geometric attacks.
