Abstract
A document authentication apparatus and system is provided comprising a scanner, PC, a central database and a network. The scanner emits a stimulus which illuminates security features such as ink, fibers or planchettes in or on a substrate of a value item such as a check, bank note, credit card or identification document. A sensor(s) detect the illuminated security features and values are generated relating to the color, coordinates on and depth of the security features in the substrate. The values are digitized and recorded for comparison when a value item is presented for authentication. Matching digitized values indicates a match of the substrates thereby identifying the value item.
