1. A method for automatically authenticating an article to determine 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 article, the second set of information differing from the first set of information; 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 for the article based on validation of a code generated for the microparticle mark and confirmation that the microparticle mark includes at least one difference between the first set and the second set of information due to characteristics that are producible only by three-dimensional microparticles; and providing a tangible indication of an authentication of the article in response to the automatic analysis of the existence and authenticity of the microparticle mark.
