视频隐写分析技术研究综述

A Survey of Video Steganalysis

作为当今最流行的传播媒介之一,数字视频被普遍视为一种理想的隐蔽通信载体,视频隐写和视频隐写分析技术也因此吸引了信息隐藏领域研究者的广泛关注,成为该领域的研究热点之一。近年来,视频隐写技术的快速发展,使得视频隐写分析面临着巨大的挑战。本文对当前视频隐写分析领域的研究现状进行了综述概括,重点阐述了关于压缩域视频隐写分析技术的研究进展。针对不同类型的嵌入域,分别归纳了相应隐写分析技术的原理,并对其中的经典方法进行了详细介绍和分析。此外,还对未来视频隐写分析领域可能的研究重点和发展方向进行了讨论和展望。

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.
