Abstract

L'invention concerne un procédé et un dispositif d'évaluation d'authenticité qui garantissent une évaluation hautement fiable de l'authenticité d'un objet ayant reçu une substance fournissant des informations. Des spectres fluorescents individuels sont stockés à l'avance, ces spectres fluorescents étant émis respectivement par un nombre fini de types de substances fournissant des informations véridiques faisant partie de substances fournissant des informations qui produisent une fluorescence lorsqu'elles sont irradiées au moyen d'une onde électromagnétique dans une région de longueur d'ondes spécifiée. Un objet (90) destiné à être soumis à une évaluation d'authenticité est irradié au moyen d'une onde électromagnétique dans une région de longueur d'ondes spécifiée afin de détecter un spectre fluorescent émis par l'objet. Une fois détecté, le spectre fluorescent émis par l'objet est reproduit au moyen d'une combinaison de spectres fluorescents individuels d'un nombre fini de types de substances fournissant des informations véridiques stockées à l'avance et, s'il ne peut pas être reproduit, l'objet (90) est jugé faux.
