Abstract
Abstract Verifiable Secret Image Sharing has become an important field of study in modern cryptography. As the era demands the need of security and verifiability to resist cheating scenario, a new secret image sharing scheme identifying the existence of cheater is introduced and analyzed in this paper. A method to ensure integrity of secret image prior to its recovery is proposed. An n x n secret image and n x n verification image are used to generate shares which are embedded into a cover image for transmission. Structural similarity and mean square error measure of reconstructed verification image with original verification image verifies the coherence of the secret. Computational cost of this method is low which makes it suitable for covert message communication and sharing of scanned documents.
