Suitability of Using Julia Set Images as a Cover for Hiding Information

Steganography is a technique that is used to secret information in a cover media that ensure the secrete of messages and their existence, not notice from others. A blind steganography means that secret information can be extracted without need the original cover image. Different types of media are used as a cover in stenography techniques, such as text, image, audio or video. One of these techniques was the image that created by using algebraic Fractals, Julia set is a type of algebraic fractal, which it can be used as a cover to embedded text or images in blind steganography technique. This method used in many thesis and papers. The aim of this paper focuses on the weak points and limitations of using fractal images, especially Julia sets images, as a cover in steganography system that may contribute in detect the hidden information within these images. The importance of this paper, it gives a hint to steganography system designer to avoid these weak points which threat the security of their systems.
