Executive Summary

The growing possibilities of modern communications require a special means of confidential and intellectual property protection against unauthorized access and use. Cryptography provides important tools for the protection of information and they are used in many aspects of computer security. This paper makes use of encrypted secret sharing to increases the security level of hidden data and to provide Mutual Authentication of the users. The visual cryptography scheme is a perfect secure method that encrypts a secret image by breaking it into shadow images. A distinctive property of visual cryptography scheme is that one can visually, without computation, decode the secret by superimposing shadow images.
