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 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 determine the authenticity of the microparticle mark based on a confirmation that the microparticle mark includes at least one three-dimensional microparticle due to the mark presenting at least one difference between the first set and the second set of information arising from characteristics that are 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.
