| Research Abstract |
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
