In this proposed method, the lower and higher frequency subbands of the decomposed original image are modified by inserting the watermark information using different transforms. The implementation of a method that combines the visual cryptography with dual image watermarking to provide the security for the digital images during an exchange in open networks. The Arnold transform is used to encrypt the second watermark to employ the secure communication. Based on the proposed, the perceptibility and robustness of the distributed images can be increased. The original and watermarked images look like same and the PSNR and NCC are calculated for analyzing the system performance. This method is more robust and secure than existing methods.
