SECURE VISUAL CRYPTOGRAPHY SCHEME WITH MEANINGFUL SHARES

摘要

Visual cryptography is an outstanding design, which is also known as visual secret sharing. Itused to encode a secret portrait into various pointless share images. Normally, item bossed ontransparencies and decrypts as loading one or two or the entire share images by means of the human visualsystem. Suppose, if we encompass great sets of secret shares then the pointless shares are complicated tohandle. In this paper, a meaningful secret sharing algorithm and a modified Signcryption algorithm is usedto enhance the security of the Visual Cryptography encryption schemes. The foremost intend of theanticipated format is to extend consequential shares and similarly make sure the isolation on conveying thesecret data. The anticipated process is executed in the functioning platform of MATLAB and thepresentation results are investigated.
