Paper Abstract

This paper deals with the creative search for security devices that thwart criminals, in particular forgers, that attack banking instruments. Because this activity requires an innovative mind, knowledge of engineering and a sense of pioneering, it is coined 'inventioneering.' Some fully new solutions and practical examples are discussed: carbon-based ink number in cheques, perforated number in cards and cheques, diffractive personalization of OVDs, protecting the toner of laser printers against alteration, and micro laser engraving.
