الملخص الإنجليزي

In this thesis we introduce a new method for hiding information as images then decrypt them to find the message. Many of us lump cryptography with Steganography, it's true that the later is a way to encrypt the information, but still there are differences.

These differences will be cleared in this thesis. We suggested a method to hide the information by the self similarity patterns of fractals, using the affine transformation, to create the image as the attractor of the iterated function system.

The privilege of the IFS is that we can send long messages, as just one image.

That is by embedding the information as a text in an image and extracting it Decoding the attractor by Barnsley's collage method is to find the values of the coefficients that created the image, that in fact are the letters of the message that are hidden in an innocent colored image.
