Separable Data Hiding in Image using AES Algorithm

In today¿s world, internet is the only medium to transfer information from one end to another across over the world. There is possibility of secret data can steal in many ways by the internet. Cryptography and data hiding are the most usually used methods for improving the data security. Using Cryptography secret data can encrypt then by data hiding techniques it can hide in cover image after that sending it to a sender. Data hiding is the technique in that secret information was concealed into another cover image. An image containing secret information seems same as the cover image. In this paper, we analyze AES algorithm with different modes of operation (block cipher) regarding PSNR, MSE & Histogram, etc. as well as comparing those results with another existing algorithm RC4 (Stream cipher).
