ABSTRACT
It is not safe to rely on internet to store all the information because of tremendous realization and growth in the field of internet technology and hacking. For personal privacy protection, it?s needed to secure data while transmission through electronic media. Image encryption is one of the innovative are a in this era of Internet technology. The algorithm mainly deals with Image Processing, Visual Cryptography and Steganography. In this paper, any image from the applicant is processed in such a way that it is pre-processed and encrypted first using standard AES algorithm. Pixels of encrypted image are modified by Chaotic Genetic Algorithm. This modified image is embedded in Cover image using Steganography. Decomposition of this image is done using Discrete Wavelet Transform. One approximate share of output image is given to the applicant and all other shares are preserved in the database. The applicant need to provide his share during every transaction and those shares are over lapped with the already existing shares in the database and a check for authentication is done by using correlation technique. If a higher correlation co-efficient is achieved, then the authentication is succeeded. Also, value of MSE is lower so the Error.
