Summary:Described are systems for combining multiple latent characteristics within a pigment such that with certain specialized knowledge and tools the specific pigment can be uniquely authenticated. The system takes advantage of the rapid proliferation of artificial light sources that are characterized by combinations of narrow band light sources that combine to simulate natural, or broadband light sources. With knowledge of the ambient lighting spectral emissions and the ability to illuminate the subject with an alternative light source with different spectral emissions, it is possible to determine the presence of the latent characteristics within the pigment. In some embodiments of the system, a smartphone including a CMOS or CCD sensor and a LED light source, could be combined with software to authenticate all of the latent characteristics. These characteristics can be combined with each other in different proportions to mass customize unique solutions for each customer or product line.
