Abstract
This paper introduces a novel image stegano graphic method for embedding secret image information into digital images. The proposed algorithm uses a fractal image as the cover image, takes a random-like sequence generated by a chaotic map as the reference for embedded positions, and employs a wavelet transform to realize the embedding procedure. The fractal cover image that can be parametrically generated implies a cover image could be unique in the world. The chaotic logistic map guarantees that the sequence of embedding positions is completely unknown for an adversary and the embedding procedure is almost random-like. The wavelet transform ensures the secret information is only embedded within edges with the least visual distortion. The proposed scheme is tested over different cover images and secret images and simulations results demonstrate its effectiveness and robustness.
