New Technique of Forensic Analysis for Digital Cameras in Mobile Devices

Abstract

Nowadays, forensic analysis of digital images is especially important, given the high use of digital cameras in mobile devices. The identification of the device type or the make and model of image source are two important branches of forensic analysis of digital images. In this paper we have addressed both, with an approach based on different types of image features and the classification using support vector machines. The study mainly has focused on images created with mobile devices and as a result, the techniques and features have been adapted or created for this purpose. There have been a total of 36 experiments classified into 5 sets, in order to test different configurations of the techniques. In the configuration of the experiments were taken into account among other things the future use of the technique by the forensic analyst in real situations and creating experiments with high technical requirements.
