Development and future of information hiding in image transformation domain: A literature review

Information hiding technology is a technique to hide meaningful information in the public carrier information. When data elements are becoming more and more important, information hiding technology has a better performance than traditional encryption and decryption technologies such as single table substitution and Virginia cipher. Since it contains redundant information, image is a common carrier for information hiding among many carrier types. As one of the primary means of information hiding technology, image transform-domain information hiding technology has been widely studied and used in academic and industrial fields. Information hiding in the image transform domain improves security and robustness effectively. This paper mainly introduces the concepts, principles, processes, mainstream algorithms and applications of image transform-domain information hiding techniques. A possible general future development of it is also depicted.
