| Abstract: |
| Digital video has become one of the most influential media, and video transmission is widely believed to be an ideal cloak for covert communication. Thus, video steganography and steganalysis have received much attention from the research community and become a hot research topic in the field of information hiding. In recent years, the rapid development of video steganographic techniques has posed a serious challenge to video steganalysis. In this article, the progress of research on video steganalysis is surveyed, and the steganalytic techniques in compressed video domain are graphically illustrated. The basic principles of specific video steganalysis targeted at different embedding domains are explained, with the elaboration of some representative methods. In addition, the future direction of video steganalysis is further discussed. |
