Abstract

Now a day, every sensitive data must be secured. Visual cryptography is a technique to hide the image based secret. In visual cryptography the secret image is encrypted in to shares and at decryption side all shares are superimposed with each other so that secret is revealed. The key feature of visual cryptography is that, no difficult computation is needed at decryption side to decrypt the secret. In this paper various visual cryptographic techniques are discussed and performance analysis is done based on number of secret image, pixel expansion, image format, type of share generated.
