Abstract:The digital media, including text, image, graphics, audio and video etc., has become a main way for information communication along with the popularization of Internet and the development of multimedia techniques. People can get almost information through the Internet. But this gives rise to serious problems including wide spread copyright violation, illegal copying, easy forging etc. How to provide copyright protection and implement covert communication has drawn extensive attention in recent years. As a main method for covert communication and copyright protection(watermarking), information hiding has been widely studied and applied. In this paper, we make an introductory review on the information hiding techniques including the last achievement in this field. First, we give the general concepts and fundamental principles of information hiding such as the definition, characteristics, classification and general framework. Then, we analyze the processing model, the typical methods, the main application and the attack analysis of watermarking. Finally, we make a discussion on some open problems and point out possible directions for further research.
Keywords:Information hiding  Digital watermarking  Copyright protection
