Data Sharing through Multimedia Steganocryptic and Visual Cryptography System

Gajangi Rahul Kumar | U.Shivaji

Abstract: The Visual Cryptography Scheme (VCS) is a kind of secret sharing scheme that fixates on sharing secret images. The fundamental conception of the visual cryptography scheme is to split a secret image into number of desultory shares (printed on transparencies) which discretely reveals no information about the secret image other than the size of the secret image. The secret image can be reconstructed by stacking the portions. In the multimedia steganocryptic system, the message will first be encrypted utilizing public key encryption algorithm, and then this encrypted data will be obnubilated into an image file thus accomplishing both data encoding and obnubilating. The multimedia data will be acclimated to provide the cover for the information. Visual steganography is one of the most secure forms of steganography available today. It is most commonly implemented in image files. In this paper concept of visual cryptography is discussed which is an impeccably secure method of keeping images secret, for feasible use in biometric identification technique and auspice such as dactylogram images for the purpose of utilizer authentication along with sundry visual cryptography schemes as an literature review. This paper not only reviews how to apply sharing of single secrete image and multiple secrete image on ebony and white as well as on color images but withal a comparative analysis on sundry visual cryptography schemes is withal performed.
