A naive based share generation using random visual Crypto technique

Abstract

With the advancement of technology and desire of Digitalization the sensitive data that are transmitted over the internet has to be secured. Since leakage of Information can lead to security theft, which happens in cybercrime. Hence securing the data which we share over the internet is almost as important in fulfilling the desire of digitalization. With this aim visual cryptography techniques are proposed. In the encryption phase of visual cryptography shares of secret data are created to transmit over the channel. And the shares are combined at the decryption phase to regain the original data. Considering one the existing method called RGB based multiple share creation with aid of Elliptical curve cryptography. The drawback of low PSNR value of retrieved image is boosted by adopting RSA in the second stage of encryption and proposed a Novel Visual cryptography Method that results in ∞ PSNR value along with retaining maximum information with PSNR in the retrieved data after attack.
