With the modernization of technologies, it’s becoming quite easy to get private information from any person. Basically, VC is a secret message sharing method that uses distributed images as shares such that, when the distributed shares are stacked up, a concealed secret picture is revealed. No cryptographic computations are needed to decrypt the encryption images, rather it uses the human vision. In the existing visual cryptographic method during the creation of private key(mask key) automatically some changes are made in key data due to which during the time of decryption the quality of the picture decreases. In this paper, we proposed a new method of public and alter key encryption method for color images and without any pixel expansion which requires less space. In this method, all the changes made in the private key during creation are stored in the alter key for the decryption of images.

Keywords- Visual Cryptography(VC), Halftone color images, Pixel Expansion, PSNR, Private key, Alter key
