针对H．265 /HEVC 压缩编码视频中帧删除、帧重复及帧插入等时间域篡改问题， 根据H．265 /HEVC 编码标准的新特点，文中提出了一种基于视频压缩特征的时间域篡改 检测算法．该算法通过利用视频压缩域的相关参数，在不需对视频进行完全解码的情况下 实现篡改位置的检测．实验结果表明，文中提出的算法对不同程度的帧删除、帧重复和帧 插入篡改以及不同压缩码率的篡改视频都具有较好的检测效果，有效缩短检测时间．

In order to solve such time domain forgery problems as the deleting,duplication and insertion of frames in H.265 /HEVC compressed videos,according to new features of H.265 /HEVC coding standard,a time domain forgery detection algorithm on the basis of video compression features is proposed.In the algorithm,with the parameters in the compressed domain of the videos,the position of forgery can be detected without decoding the videos completely.Experimental results show that the proposed algorithm shows good performance in detecting varying degrees of deleting,duplication and insertion of frames as well as different bitrates of forgery videos,and it can also shorten detection time effectively.
