Secret Image Sharing using Verifiable method has become an important field in cryptography in today's world. Security is of main concern and verifiability has become a demand of this era in order to avoid cheating prevention and a new scheme of secret image sharing scheme for identification of the presence of cheater is has been analyzed and described. A method for ensuring integrity of secret image prior to its recovery is proposed. An secret image and verification image are used to create shares by ARGB to CMYK conversions which are sent via cover image for transmission. The shares created are meaningful therefore this method is able of identifying whether cheater exists or not in order to preserve the integrity of the image.
Visual Cryptographic technique has become an important field of study in modern cryptography. Visual cryptography (VC) has quite a few applications and some of them are authentication and identification, steganography, and image encryption. As the era demands the need of security and Visual Secret Sharing to resist cheating scenario is a Visual Cryptographic technique. VSS is simple as it is easily detectable by human visual system. A secret image sharing scheme is used for identifying the existence of cheater. The use of verifiable scheme leads helps find the presence of a cheater. The problem of cheating prevention exists and researchers have proposed scheme like Cheating-prevention visual secret-sharing (CPVSS) schemes. This paper is based on the study of the cheating prevention happening in Visual Cryptography.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
