For that, it is necessary to improve the structure for patent safety, defense against duplication, and validation of documents.visual cryptography would examined execution will be assessed with respect to four criteria: amount of mystery images, pixel expansion, and image design What's more kind from claiming allotment produced. To protect data against Dual RST(Rotation, Scaling and Translation) attacks approach of DWT+SVD in block manner with Pseudo Zernike Moment and features extraction of surf. So, on Affine transformation is used to recover rotational value and recover watermarked image data.
