Studies of information hiding detection in images

Information hiding includes steganography and digital watermark. The application of steganography can be traced to ancient time, and it is also an important means of secret communication in recent years. Information hiding analysis is the art of detecting the message' s existence or destroying the steganographic cover in order to blockade the secret communication. And information hiding detection is the very first step in information hiding analysis. Firstly, architectonic analysis about information hiding detection is proposed, including the analysis of digital image characteristics, image-based detecting algorithms and some problems in its realization. Secondly, many detecting algorithms are introduced with theoretical analyses and experimental results in details. Thirdly, two applications of detecting technology are put forward. Finally, a detecting model used in Internet is discussed.
