Abstract: Forensic characterization of devices is important in many situations such as establishing the trust and verifying authenticity of data and the device that created it. Current forensic identification techniques for digital cameras, scanners and printers are highly reliable due to the fact that each of these devices cannot escape inherent electro-mechanical properties which add "signatures" to the data they produce. In this paper we will describe the sensor forensics work going on at Purdue University.
