Steganogallery: Steganographic gallery

This paper presents a new steganographic method called steganogallery, which means steganographic gallery. It enables us to imperceptibly embed secret information into a sequence of images. The images provided for embedding are just used to form the sequence. In other words, the images are not modified through embedding, while almost all of the image based steganographic methods do modify images for embedding data. The sequence is saved into a file in a plausible form, from which we can restore the embedded information. A prototype system has been developed and tested. It has been shown that the proposed framework of steganogallery does work in principle.
