Abstract

A cryptographic technique for protecting medical data picture is proposed based on visual cryptography. A protected picture and a binary image as a key to encrypt and decode are used as input. The YCbCr color scheme is used to divide a secret color image into three monochrome images that must be communicated. The monochromatic photographs are then converted into binary images, which are subsequently encrypted with a binary key image known as share-l to generate binary cypher images. The Exclusive OR operation is used to encrypt the binary key image and the three half-tones of the secret color picture. By mixing these binary images, Share-2 is formed. By mixing these binary images, Share-2 is formed. The parts are decrypted, and the recoverable binary pictures are halftoned and blended to create the secret shade image. This method is more successful for transmitting natural sights through unsecure channels.
