Visual secret sharing

Abstract

Multiple secret sharing (SS) scheme is a cryptosystem which encrypts a secret into multiple shares so that any qualified combination of shares can reconstruct the secret, while any forbidden combination of shares reveals no information about the secret In the existing process, the system has more complex stages by introducing two stages for making secure VSS. The first stage is message based privacy. The Secret Share content was Reversed and content is encrypted with the help of triple DES algorithm. The second stage is image based privacy. The image based privacy is applied by embedding encrypted message and user key into multi-media object(image) using LSB based water marking Techniques and then the image is encrypted using AES algorithm. The encrypted image is segmented into shares by file merge and split algorithm. The user key and shares are sent to receiver through mail. The valid receiver can be able to reconstruct the shares into image. By using the user key encrypted message will be obtained. Then the message will be decrypted and reversed to get the secret message. Through this approach the new system improve our privacy and protection of secret sharing.
