Abstract: Forensic analysis of individual printed items, including single characters, provides a readily- integrated means to extend security to any printed item (label, document, package, etc.). In this paper we demonstrate, for the first time, forensic levels of image inspection for workflows involving two very different high-resolution imaging devices, the Dyson Relay CMOS Imaging Device (DrCID) and a high speed line-scan camera. In particular, we show how a similarity metric can be used to identify specific characters with less than 1 in 109 chance of false matching, while closing the loop between in-line (production) using the line-scan camera and end-user (investigative) inspection with DrCID.
