The proposed method deals with the visual cryptography using a new combined technique called SVD technique with frequency domain watermarking technique. SVD technique and Frequency domain watermarking technique results in high PSNR, moderate the difficulty of the design and moderate time required for computation and compared to predictable VC techniques. In this paper Frequency Domain (FD) watermarking technique is used to prevent distorts attacks in the VC scheme. FD watermarking technique
