Exploration of Color Visual Cryptography Schemes

Jinu Mohan | Dr. Rajesh.R

Abstract: Secret sharing is a method for distributing a secret among a group of participants. Visual Cryptography is a form of Visual Secret Sharing proposed by Moni Naor and Adi Shamir. Visual Cryptography Schemes hide the secret image into two or more images which are called shares. The secret image can be recovered simply by stacking the shares together without any complex computation involved. Color Visual Cryptography encrypts a color secret message into color halftone image shares. In this paper the various Visual Cryptography schemes are discussed and try to summarize the recent developments in Color Visual Cryptography technology.

Keywords: Visual Cryptography, Color Visual Cryptography, Halftone Technique, Color Decomposition, Meaningful Shares
