摘　　要：随着个人计算能力的提升和视频编辑软件的普及,大量经过编辑的数字视频资源涌入我们的生活,如何辨别这些视频资源的原始性和真实性已成为多媒体安全领域的1个研究热点。本文针对视频编辑工具软件MSU LogoRemover的篡改特点进行深入分析,提出了1种针对性的区域篡改检测算法,它充分利用视频编辑过程中的滤波处理对视频图像高频能量的影响,构建相应的篡改检测特征。实验结果说明,该算法在检测区域篡改上有很好的效果,并能够较为精确地定位篡改区域。With the promotion of personal computing ability and the extensive application of video editing software,a lot of tamper videos are filled in our life.How to distinguish the authenticity and aboriginality of the video has become a focus of social concern.The proposed filtering detection algorithm is aim to video tampering using the software of MSU Logo Remover.The algorithm is deeply researched and tested the feature according to filtering process which will bring to the loss of the high frequency energy.The corresponding tamper detection feature is constructed on the basis of it.Experimental results show that the method has good effect on detecting region-duplication.It can easily determine whether the video was tampered and locate tampered regions if it was tampered.
