Title: METHOD AND DEVICE FOR VERIFYING AN ELECTROLUMINESCENT SECURITY FEATURE IN A VALUE OR SECURITY DOCUMENT
Abstract:
The invention relates to a method for verifying an electroluminescent security feature (2) in a value or security document (3), comprising the following steps: exciting the electroluminescent security feature (2) by a predetermined input signal (8) using an electric field by an excitation device (4), detecting a luminescence (9) emitted by the electroluminescent security feature (2) and converting the detected luminescence (9) into an output signal (11) by a detection device (5), transforming the output signal (11) by means of a provided characteristic function (12) by an evaluation device (6), evaluating the transformed output signal (14) while taking into account at least one input signal information (16) of the input signal (8) for deriving a verification decision (18) by the evaluation device (6), outputting the verification decision (18) by the evaluation device (6). The invention further relates to an associated device (19).
