Abstract
A system and method are described for identifying a photographic camera model from a photograph taking the form of an optionally TIFF-compressed image and fulfilling a relationship between the expectation and the variance of the pixels of the image. This relationship is dependent, inter alia, on two parameters, “c” and “d”, and these two parameters determine a fingerprint characterising the camera model. The system includes an image processing device that can process the photograph to estimate parameters “c” and “d”. The system also includes a device for carrying out statistical hypothesis tests on the distribution of the pixels of the photograph and a statistical analysis device for determining if the photograph was taken by the camera model by comparing the “c” and “d” parameters obtained from the photograph and the known “c” and “d” parameters of the camera model.
