摘要

As we all know that Visual cryptography is an important powerful technique which is related to Image encryption. With the help of normal cryptographic techniques, we are encrypting the secret for secure transmission and decrypting the secret according to our need. Visual cryptography scheme, mainly used for images. These schemes hide the secret image into two or more images which are called shares or transparencies. The secret image can be recovered simply by stacking the shares together without any complex computations at the receiver side. The shares are very safe because these shares reveals nothing about the secret image. The main advantage of Visual Cryptography scheme over normal cryptographic techniques is that it does not requires complex computations at the receiver side. Here proposes a Visual cryptography scheme for preserving the color of the secret image for avoiding the disadvantages of the existing schemes.
