Secured data communication system using RSA with mersenne primes and Steganography

To add multiple layers of security our present work proposes a method for integrating together cryptography and Steganography for secure communication using an image file. We have used here combination of cryptography and steganography that can hide a text in an image in such a way so as to prevent any possible suspicion of having a hidden text, after RSA cipher. It offers privacy and high security through the communication channel.
