Three-dimensional authentication of mircoparticle mark
First Claim
1. A method for determining an authenticity of a microparticle mark having a plurality of microparticles, comprising:
- acquiring at least a first set and a second set of information from the microparticle mark, each set of information based at least in part on the existence of the plurality of microparticles and each set of information being acquired under differing conditions based upon variations in characteristics that are producible only by three-dimensional microparticles in the microparticle mark;
using a processing system to perform an automatic analysis of at least the first set and the second set of information to confirm that the microparticle mark includes at least one three-dimensional microparticle due to the mark presenting a difference between at least one characteristic from the first set and the same characteristic from the second set of information arising from at least one variation in the at least one characteristic that is producible only by three-dimensional microparticles; and
providing a tangible indication of an authentication of the microparticle mark in response to the automatic analysis determining the existence of at least one three-dimensional microparticle in the microparticle mark.

Abstract
A system, method, and apparatus for authenticating microparticle marks or marks including other three-dimensional objects. The authentication utilizes two or more sets of information captured or acquired for the mark in response to illumination of the mark by electromagnetic energy such as in the visible frequency range. These sets of information are then used to verify that the mark includes three-dimensional objects such as microparticles. The two or more sets of information about the mark preferably vary from each other in time, space/directionality, color, frequency or any combinations thereof, and can be captured or acquired as part of one, two, or more images of the microparticle mark.
