This paper describes methods for forensic characterization of imaging devices. This is important in verifying the trust and authenticity of data and the device that created it. Current forensic identification techniques for imaging devices, such as digital cameras, scanners, and printers, are presented. We discuss our ongoing research in creating a forensic framework for these devices. Also discussed are methods we have developed for securely embedding a separate communications channel in the device output.
