ABSTRACT

Visual Cryptography is a special kind of cryptographic scheme where the decryption of the encrypted secret is done by the human vision and not by complex mathematical calculations. Visual Cryptography deals with any secrets such as printed or pictures, etc. These secrets are fed into the system in a digital (image) form. The digital form of the secrets is then divided into different parts based on the pixel of the digital secret. These parts are called shares. The shares are then overlapped correctly to visualize the secret. This paper shows the different applicable areas of Visual Cryptography.
