Development of a video tampering detection method based on the individual characteristics of imaging devices

提出了一种视频篡改检测方法。在本研究中，由于半导体成像器件中每个像素的电特性变化而导致的个体特性被分析用于篡改检测。该方法可以指定篡改的空间和时间位置以及是否存在篡改。在摄像机可用的情况下，该方法可以检测到图像内容篡改和场景插入。在此基础上，提出了一种在未知摄像机成像的情况下检测场景插入的方法

A video tampering detection method has been developed. In this study, individual characteristics due to variations in the electrical characteristics of each pixel in a semiconductor imaging device was analyzed for tampering detection. Spatial and temporal position of tampering as well as the presence of tampering could be specified with the method. Image content tampering and scene insertion could be detected with the proposed method under the condition of the recording camera was available. Furthermore, a method which is capable of detecting scene insertion has been developed in the case of unknown camera was used for imaging
