Abstract

Visual Cryptography(VC), an emerging technology for secret sharing which allows visual information (pictures, text, etc. ) to be encrypted in such a way that the decryption can be performed by the human vision system(HVS). Originally it was proposed by Naor and Shamir in 1994 for black and white images. Later this technique is extended for gray level images as well as for color images. This paper compares and analyze the performance of various VCS on various parameters such as pixel expansion, contrast, shares generated etc. The compared algorithms came into aura by rectifying limitations of one another.
