A hybrid fractal-wavelet data hiding technique

The need for secret communications is as old as the communication itself [1]. With the rapid growth of the information age accompanied by intensive transfer of multimedia content, data hiding techniques have taken an important role. Its applications have ranged from copyright protection and property assurance to content authentication and steganography. In this paper, a new steganography technique is proposed for hiding images. It adopts both fractal and wavelet image processing techniques. The idea of the presented scheme is to hide the fractal codebook of a to-be-hidden image in the wavelet domain of a host or hiding image. The presented technique had been tested and proved its robustness against additive white Gaussian noise AWGN.
