Visual Cryptography BaseShuffling Method for Securing Medical Images

Abstract

Visual Cryptography is a special encryption technique to encrypted visual information, which divides secret visual information into multiple layers Called shares, Each share holds some information. The receiver aligns the shares and the secret information is revealed by human vision without any complex computation. This thesis focuses on the visual cryptographic technique for encrypting of medical images before transmission or storage of them, This will make such images inaccessible by unauthorized personnel and also ensures confidentiality, The process made use of an encryption technique that is based on pixel shuffling and a secret key generated from the image, The algorithm is analyzed, based on the result of the analysis the difference between the plain image and the image rate was found after decoded is equal to zero.
