Abstract

In security printing in general and currency printing in particular, it is very rare for a single security feature to carry the total burden of 'authenticity.' There is almost always a layering of features, which in their complexity and coherence eventually determine the genuine. We give examples to show holography is no exception to the rule of layering. After discussing the integration of various layered holographic features into a security product, the paper discusses currency, proposing authentication of currency is, today, fundamentally a human perception and that the human eye is more attuned to recognition of a face than a machine readable random pattern.
