    摘要： In part, the invention relates to a security feature for authenticating an object having an outer surface and an inner surface. The security feature includes a substrate having a length and a width and a two-dimensional code comprising a plurality of two dimensional regions, the plurality of two dimensional regions disposed in the substrate, the two-dimensional code is substantially invisible when inspected during exposure to visible light and readable during exposure to ultraviolet light.

    摘要： Disclosed are security articles and methods and systems for authenticating security articles using a plurality of stimuli. According to one embodiment, an illustrative secured article includes an embedded feature wherein differential activation of phosphorescent or fluorescent materials creates a machine readable response through the simultaneous presence of a source of electromagnetic radiation and a specific gas environment. A detector detects a differential spectral emission across the security feature that results from the change in gas environment. The spectral emission may be compared to an expected emissive signature to determine authenticity of the security article.

    摘要： An authenticable and machine readable coating for pills, tablets and other ingestible materials is provided. The disclosure also relates to methods of authenticating the same. The coatings are formed from a lattice of particles stacked to cause selective diffraction such that each pill or tablet has an optical signature. The signature associated with each coating can be read and authenticated. In one embodiment, the particles are substantially spherical and self-organized. In one embodiment, generally recognized as safe (GRAS) materials are used to form the particles.
