Visual Cryptography Using Hybrid Halftoning

Abstract

AbstractVisual Cryptography is the study of mathematical techniques related aspects of Security which allows Visual information to be encrypted in such a way that their decryption can be performed by the human visual system, without any complex cryptographic algorithms. Visual cryptography scheme is used to encrypt an image into multiple shares and is distributed among different participants. A minimum number of shares if overlapped could reveal the hidden information visually. In a computer a logical OR operation could reveal the same information.We propose the significance in use of hybrid halftoning in visual cryptography. We also propose a new technique in hiding the information that the encrypted shares are encrypted by inter-pixel exchanging using a secondary image.
