Automated reagentless system of product fingerprint authentication and trademark protection
First Claim
1. A method for authenticating products comprising:
- a. sampling a representative series of randomly selected units of known products from a homonymous lot of known products manufactured in a single production cycle from identical raw materials and optional intermediates;
b. obtaining light transmitted, luminescent and Raman scattering values for the series of known products to produce a signature for the known product;
c. sampling an unknown product to obtain light transmitted, luminescent and Raman scattering values for the unknown product to produce a signature for the unknown product; and
d. comparing the signature of the known product and the unknown product to determine if the signature of the unknown product is the same as the known product.

Abstract
A certification, marking and automated nondestructive product authentication system that identifies a specific manufacturer'"'"'s product at all states of sale. The system detects counterfeit products and/or product contamination with alien admixtures. The system uses spectral analysis method to produce a card creating image, signature, fingerprints, and/or data profiles that unambiguously characterize the product of specific manufacturers and provide secure trademark protection. The system allows contact-free control of a packaged product without breaking the integrity of the original manufacturer'"'"'s packaging, which is achieved by using special material for package fabrication or by equipping the package with a special device made of such material.
