Paper Abstract

The continued development of reprographic technology and computer graphics (notably color laser copiers, scanners and color laser printers) has increased the tools available to both professional and casual counterfeiters. The result is an increase in the counterfeit risk to the U.S. dollar and other currencies. To counter these threats improved methods of currency authentication are needed both for use by the general public and by national currency authorities. The growing number of cash transfer machines has increased the importance of machine readable security features. This paper describes some technology based approaches to currency security based on special materials. It also proposes a metaphor for currency authentication which attempts to provide a framework for unifying approaches based on secure features and those based on codes.
