Abstract:

Systems and methods authenticate an object using IR. IR is projected at a first wavelength onto the object and a first image of the object is captured during the projection of the IR. The object is authenticated by processing the first image to detect IR fluorescence from an IR fluorescing material incorporated into the object in response to the projected IR, where presence of the IR fluorescence within the first image indicates authentication of the object.
