Forensic Authentication of Data Bearing Halftones

Stephen Pollard, Robert Ulichney, Matthew Gaubatz, Steven Simske

Abstract

This paper introduces a practical system for combining overt, covert and forensic information in a single, small printed feature. The overt “carrier” feature need not be a dedicated security mark such as a 2D or color barcode, but can instead be integrated into a desirable object such as a logo as part of the aesthetically-desired layout using steganographic halftones (Stegatones). High-resolution imaging in combination with highly accurate and robust image registration is used to recover, simultaneously, a unique identity suitable for associating a unique print with an on-line database and a unique forensic signature that is both tamper and copy sensitive.
