Title (DE) VERFAHREN ZUR ECHTHEITSPRÜFUNG EINES DATENTRÄGERS
(EN) METHOD OF CHECKING THE AUTHENTICITY OF A DATA CARRIER
(FR) PROCEDE PERMETTANT DE VERIFIER L'AUTHENTICITE D'UN SUPPORT DE DONNEES
Abstract:
(DE) Die Erfindung betrifft ein Verfahren zur Echtheitsprüfung eines Datenträgers mit einem integrierten Schaltkreis und zeichnet sich dadurch aus, daß in einem Bereich des integrierten Schaltkreises ein Material vorgesehen ist, das durch eine elektromagnetische Strahlung oder durch ein elektrisches Feld beispielsweise zur Lumineszenz angeregt wird, wobei die von dem Material emittierte elektromagnetische Strahlung gemessen und zur Echtheitsbestimmung des Datenträgers ausgewertet wird.
(EN) The invention concerns a method of checking the authenticity of a data carrier with an integrated circuit and is characterized in that a material which is excited to provide luminescence, for example, by electromagnetic radiation or an electrical field is provided in a region of the integrated circuit. The electromagnetic radiation emitted by the material is measured and evaluated in order to determine the authenticity of the data carrier.
(FR) L'invention concerne un procédé permettant de vérifier l'authenticité d'un support de données comportant un circuit intégré. Ce procédé se caractérise en ce que, dans une zone du circuit intégré, il est prévu un matériau stimulé par un rayonnement électromagnétique ou par un champ électrique, par exemple pour produire une luminescence. Le rayonnement électromagnétique émis par le matériau est mesuré et évalué pour permettre de déterminer l'authenticité du support de données.
