Abstract

Visual Cryptography is one of the ways, to share the visual secret information securely. Visual Cryptography Scheme (VCS) is an encryption method which provides information security that uses combinatorial techniques to encode secret written materials, without any complex cryptographic algorithms. We propose a new Multi-secret based Semantic Visual Cryptographic Protocol (MSVCP) that can encode the two secret images into the shares using error reduction. The implementation part begins with converting a grayscale image into a semantic image through error reduction, followed by embedding semantic image into n shares. Finally, secret image will reconstruct without showing any interference with the share images. The proposed a novel scheme called a MSVCP, which can be applied to grayscale images. The experimental result shows the effectiveness and advantages of the proposed MSVCP and it ensures the security and quality of the reconstructed secret images.
