Analysis & Design of Secure and Contrast Enhanced Secret Sharing Scheme Using Progressive Visual Cryptography

Shivam Sharma ^[13] | P. Priyadarshni

Abstract: Visual cryptography is a system offering arrangement which uses pictures flowed as shares such that, when the shares are stack, a touchy or emit picture is uncovered. As per expanded visual cryptography, the offer pictures are manufactured to hold convincing spread pictures, in like manner giving open avenues to organizing visual cryptography and biometric security routines. In this paper, we propose a plan for halftone pictures that improves the way of the shares produced from discharge picture and the recovered emit picture in an amplified visual cryptography plan for which the figure size of the mystery pictures and the reproduced picture by stacking shares is the comparative concerning the first halftone emit picture. The resulting arrangement maintains the perfect security of the initially created visual cryptography approach. This methodology incorporates 2x2 piece substitution for creating shares from emit picture.
