Description
Summary:In order to improve the security of steganography system, this paper presents a scheme of steganography based on fractal images. This method makes use of good properties of creation of fractal images, such as ease of generation, sensitive dependence on their initial condition, information are embedded during creating fractal images by secret information and initial parameters. The receiver can extract secret information by comparing the difference between Stego-Images and Cover-Images recovered with the same initial parameters. The attackers can't recover the Cover-Images without initial parameters, then don't get secret information. On the other hand, the embedding and extracting are unsymmetrical, so the scheme has higher security and do well in resisting different steganalysis. Experiments show that the scheme has good imperceptibility and undetectability. The results of this paper have practical significance in extending the study of steganography.
