Using Fractals in Information Hiding


Fractals are generated by simple, recursive calculations. Encryption anddecryption algorithms that take advantage of fractals are developed. This paper presents a new approach for information hiding using iterated function system (IFS) this approach exploits the main feature of fractals (generated by IFS). So that any individual that happens to find the transformed message, will not be able to understand it; without the correct method that will reverse the transformation,usually through some knowledge of key agreement, with the original encrypted. Also to make the encoding more difficult to introducers we use steganographic methods to hide the attractor image in another colored image 256X256 pixels size.
