Abstract

This paper presents a novel visual cryptography is a kind of digital image encryption, but it is different then compare to traditional cryptography techniques because of that it needs less complex time to decrypt the encrypted data. At present so most of the products are using this technology visual cryptography is split the secret image into number of random shares seperatly no information about secret image beyond the size of the secret image. This secured image can be reconstructed by grouping the all shares, here the main play role of this scheme is logical OR operation. This technique can be implemented encryption and decryption by rand shares of secret image into meaningful convert image. This paper presents study and performance analysis of visual cryptography technique on pixel expansion, various secret images shares generated.
