Claim Text:
1. An authentication system comprising: randomly printed light-generating devices on a substrate, wherein the light-generating devices comprise light emitting diodes (LEDs), wherein the LEDs are connected in parallel such that all the LEDs on the substrate are illuminated at the same time, the randomly printed LEDs on the substrate being an authentication tool; an energization system, external to the substrate, configured for providing power to the LEDs to cause all LEDs on the substrate to be illuminated at the same time, wherein the illuminated LEDs create a static light pattern; an optical detector configured for detecting the static light pattern from the LEDs in the authentication tool after the LEDs have been illuminated; a processing system coupled to the detector and configured to generate a first code corresponding to the static light pattern; a communication system coupled to transmit the first code to a database storing pre-stored codes; and an interface system configured to convey that the first code matched one of the pre-stored codes, signifying that the authentication tool is authentic.
