Gabor Transform based Image Steganography
S Mythreyi, V. Vaidehi · IETE Journal of Research · 2007
In this paper a scheme for steganography namely Gabor Transfrom based Image Steganography (GTIS) is proposed. In this scheme, image steganography is achieved using Gabor compression. In normal methods of steganography, the secret message is distributed in all pixels whereas in this scheme the distribution of secret message is more in high complex areas and less in low complex areas. Moreover for embedding the secret message over the image, pixel positions are obtained by Pseudo Random Number Generator. The password that is used by the generator function is known only to the sender and the receiver. Some of the inadequacies that have been identified in the literatures surveyed like known location storage, absolute compression etc have been overcome by GTIS. The experimental results prove the above claim. The quality and the histogram of the stegano image are very close to that of the original one. In addition, this scheme can survive efficient lossless compression for hiding data.
