ABSTRACT:
A method for identifying/authenticating a product. The method includes providing a substrate coupled to the product that includes an identification pattern within a region of interest and imaging the region of interest of the substrate to identify identification particles of the identification pattern. For the identified identification particles in the region of interest, calculating a mathematical value representative of a position of the particle relative to at least one other identification particle and converting the mathematical values of the identified identification particles into an identification value representative of the identified identification particles. The identification value is compared with stored identification values in a database to identify/authenticate the product. Alternately, or in addition, the identification value is compared to an identification value decoded from a bar code imprinted on the product.
