Abstract : In Visual Cryptographic Scheme (emVCS/em) reversing operations (NOT operations) are carried out during reconstruction process to improve the quality of the reconstructed secret image. Many studies were reported on using reversing operation in both perfect and nonperfect blacknbsp;emVCS/em. In 2005, Cimato et al. put forward an ideal contrastnbsp;emVCS/emnbsp;with reversing, which is applicable to any access structures (emIC-GA-VCS/em). Here there will not be any change in resolution for reconstructed secret image in comparison with original secret image (emKI/em). In this paper a proposal for replacing reversing operations with AND operations during reconstruction in perfect blacknbsp;emVCS/emnbsp;is shown. A comparison of the proposed modification with Cimato et al. construction and other related work are discussed in this paper.
