Abstract

Visual Cryptography (VC) is used to break an image into two random shares which when separately viewed reveals no information about the secret image. The secret image can be obtained by super imposing the two shares. Conventional visual cryptography scheme is used to encrypt a single image into n shares. The image can be decoded by using only shares. Many visual cryptographic methods use binary images only for this process. This doesn’t suits well for many applications. First, the formulation of access structures for a single secret is transformed to that for multiple secrets. A sufficient condition to be satisfied by the encryption of MSS (Multiple Secret Sharing) schemes realizing an access structure for multiple secrets of the most general form is introduced, and two constructions of MSS schemes with encryption satisfying this condition are provided. Each of the two constructions has its advantage against the other; one is more general and can generate MSS schemes with strictly better contrast and pixel expansion than the other, while the other has a straightforward implementation.The main objective of this project is to establish a secured communication between the sender and the receiver by using emails and other communicating modes. In this work, an XOR based multi secret sharing is proposed to send secret information from the source to the destination in a secured way.
