Apparatus to analyze security features on objects
First Claim
1. An apparatus comprising:
- a camera to capture video or imagery corresponding to;
first indicia on a surface of a physical object with a first ink or dye, wherein the first ink or dye has a first emission decay rate;
second indicia on the surface with a second ink or dye, wherein the second ink or dye includes a second emission decay rate, wherein the first emission decay rate is relatively shorter than the second emission decay rate, wherein the first indicia and second indicia are configured to collectively convey a first code when the first ink or dye and the second ink or dye are excited by non-visible light; and
an electronic processor programmed to read a second code on the second indicia, wherein the second code becomes readable as emissions from the first ink or dye decrease to a first predetermined level, but before the emissions from the second ink or dye decrease to a second predetermined level.

Abstract
The present disclosure provides apparatus for analyzing emerging security or authentication feature for physical objects (e.g., identification documents, product packaging, banknotes, etc.). One claim recites an apparatus comprising: a light source for illuminating a physical object with first non-visible light, the physical object comprising a first code provided with a first ink or dye and a second code provided with a second ink or dye, the second ink or dye comprising an emission decay time that is relatively longer than an emission decay time of the first ink or dye, the first code and the second code collectively conveying a first feature when illuminated with the first non-visible light, with the second code individually conveying a second feature after emissions attributable to the first code fall to a first level; and an electronic reader programmed for reading at least the second feature after emissions attributable to the first ink or dye fall to the first level and before emissions attributable to the second ink or dye fall to a second level. Other claims and combinations are provided as well.
