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. The property of visual secret sharing in reversible style provides more security. This method not only can fast decode without causing pixel expansion but also increase the secret-hiding ratio. Random-Grid Algorithm is used to create secret shares without pixel expansion. This paper extends the capabilities of the Visual Cryptography as a mere secret sharing technique to a Novel Mutual Authentication provider. If one stacks two transparencies(shares) together straightforwardly, a secret image will appear. Stacking two transparencies after reversing one of the transparencies, another secret image will unveil. An attempt is made to provide two transparency three-way mutual authentication by using Visual cryptography in the reversible style.

Abstract. Plane transformation visual cryptography takes a unique approach to some of the current shortcomings of current visual cryptography techniques. Typically, the direction and placement of the encrypted shares is critical when attempting to recover the secret. Many schemes are highly dependant on this stacking order. Within this paper, the scheme presented illustrates a technique whereby this restriction is loosened such that the number of acceptable alignment points is increased by performing a simple plane transform on one of the shares. This results in the same secret being recovered when the shares correctly aligned. The technique has also been extended to encompass multiple secrets, each of which can be recovered depending on the type of transformation performed on the shares.

“…Therefore, in some situations where a computer is not available to the decipherer, a vision-based secret sharing method provides an apt solution. As regards visual secret sharing research, encryption methods may differ between pixel expansion skill [4,5,6,7,8,9,10,11] and pixel non-expansion skill [12,13,14,15,16]. The majority of the sharing images generated by the above two encryption skills is chaotic, but provides meaningful images [4,9,10].…”

Visual secret checking refers to the superimposition of one key image and another public sharing image without auxiliary automated computation, in order to recognize the specified secret via human inspection. This paper achieves the goals of: guaranteeing that the related contents of a secret are not revealed after any public sharing image superimposition, confirming the accuracy of any public sharing image, and providing for the ease of management of various types of sharing images. When a user is outside of a computer environment, he/she can utilize the proposed method to discern the contents of the secret independently. Furthermore, the key image and all the sharing images have the same meaning, visible upon inspection, which allows for effective data management and classification. Through an exposition of the relevant theory, as well as experimentation, this paper provides evidence for the above claims.
