A method of authenticating an optically readable security element

Abstract

There is described a method of authenticating an optically readable security element (20) using an image capturing device (10). The method comprises illuminating S1 the optically readable security element (20) with electromagnetic radiation and reading S2 the optically readable security element (20) based on a response of the optically readable security element (20) to the illuminating S2. At least one of the illuminating S1 and the reading S2 is non-deterministic.
