Abstract

An item of a type includes one or more selected tag identifiers that are added to the item of the type. The one or more selected tag identifiers have an optical signature based at least in part on a spectral measurement of the one or more selected tag identifiers. A first item spectral measurement of a first item is detected. A first item optical signature is determined based at least in part on the detected first item spectral measurement. The first item is verified as the item of the type in the event that the first item optical signature corresponds to the optical signature of the one or more selected tag identifiers.
