Secure Approach Using Visual Cryptography

An Image Encryption and Decryption Using AES (Advance Encryption Standard) Algorithm is proposed in this paper. Visual cryptography is the most popular technique attracted various researchers to improve the security level while utilizing the images and videos as encryption key, instead of text which is easy to crack. Visual cryptography computes complex multimedia information which may leads to computational overhead when simple processing techniques and architectures were utilized. So, various researchers had taken over this challenge and trying to resolve while introducing the various high speed techniques and architectures which would make visual cryptography process highly secured and energy efficient. This paper presents an algorithm in which the image is an input to AES Encryption to get the encrypted image and the encrypted image is the input to AES Decryption to get the original image.
