视频隐写分析是信息隐藏领域一个重要的研究方面,如何在格式复杂的压缩码流中搜寻运动矢量(Motion Vector,MV)中所留下的隐藏痕迹并设计隐写分析方法成为当前的研究热点之一.视频中成像设备和拍摄对象都具有运动相似性,使得H.264视频中基于块的运动估计所生成的MV存在较强的邻域相关性,隐秘信息的嵌入将迫使MV相关性出现统计异常.本文提出了一种基于共生频率异常的MV相关性度量方法,并在此基础之上结合H.264中与MV有关的编码技术,设计了基于相关性异常的H.264视频MV隐写分析算法.在隐写分析检测和性能测试中表明,本文提出的方法能够针对H.264视频MV隐藏实现有效检测,具有检测率高、检测速度快的特点.
Video steganalysis has become an important research direction of the information hiding.How to search for motion vector(MV)hidden traces in the compressed stream with various video formats and design an effective steganalysis algorithm are hotspots in current studying.Movement in the video can be divided into two groups:the imaging equipment movement and the movement of the subject.Due to the block-matching motion estimation in H.264
strong correlations among adjacent macroblock's MV are existed.However
MV-based information hiding will cause anomalies in the correlations between MV.This paper proposes a method of correlation measurement based on anomalous co-occurrence frequency between MV
and on this basis
combined with H.264 coding technology related to MV
designs a steganalysis algorithm for H.264 video.Experimental results demonstrate that the proposed method has the advantages of high speed
and can be used to effectively detect MV-based steganography in the H.264 video.
