AB  - A new technique proposed with the combination of steganography and cryptography enhanced with
new secure feature for generating a new security system. Cryptography and steganography are two popular
ways for secure data transmission in which the former distorts a message, so it cannot be understood and
another hides a message, so it cannot be seen. In this study, a new digital message hiding system is proposed
for the combination of steganography based on fractal image compression and modified RSA with
Diffe-Hellman. The combination of these two techniques satisfies the requirements such as highly security and
robustness between sender and receiver. The proposed method ensures acceptable image quality with very
little distortion in the image. The main advantage of this system is that, the method used for modified RSA
depended on multi-prime with Diffe-Hellman algorithm which is very secure and the fractal transformation
technique is very hard to detect in image steganography. It also produces efficient robustness of stego-image
though, it had been attacked by other techniques and additionally saved from attacks. Goal of this study is to
develop a new security system that messages cannot be retrieved easily from the image by any attackers or
hackers in the communication process.
