Abstract
A method and apparatus are disclosed for determining the authenticity of secured documents which include an authentication element of the type which, when excited with radiation of a specific excitation wavelength, emits radiation which can be detected by a detection unit and evaluated by an evaluating unit. The intensity profile of the emitted radiation is determined in a specified wavelength range over a predetermined measuring period after excitation and analyzed to determine authenticity of the secured document.
