Suspect camera determination

In this study; photograph and photograph frames taken from videos were examined for suspect camera detection. These analyses were carried out on examples taken from 15 cameras, 1 video camera and 7 mobile phones. Two methods were used for suspect camera detection. Firstly, to detect dead pixel. In dead pixel analyses first step is detecting whether there is a dead pixcel on photographs by way of using some software (ex: dead pixel.exe). If there is a dead pixel, second step is to determine the location of this dead pixel on x-y coordination system. Secondly; it is a examination that is carried out on photographs/images taken from suspect cameras by using Quantitation, Exif, Average and PRNUC filters belonging to FIAS (Forensic Imaging Analysis System). As a result; in the light of the findings obtained, it is evaluated that suspect camera detection analysis can contribute to forensic digital imaging examining field.
