Abstract

La présente invention concerne un dispositif permettant de déterminer l'authenticité de produits, par exemple de produits exposés à la contrefaçon, en détectant la présence d'au moins une étiquette fixée sur les produits ou incorporée dans ceux-ci. Le dispositif d'authentification comprend un corps, un ensemble lecteur de signaux logé dans le corps, une surface accessible à l'utilisateur et une interface utilisateur. L'ensemble lecteur de signaux comporte une source d'éclairage électromagnétique destinée à exposer l'étiquette à un rayonnement. L'étiquette contient au moins une substance photosensible. L'authenticité des produits peut être vérifiée par l'intermédiaire de la détection de propriétés spectrales du rayonnement émis, diffusé ou réfléchi par l'étiquette exposée. A cette fin, la lumière émise, diffusée ou réfléchie peut être comparée à des propriétés spectrales de référence prédéfinies qui caractérisent une étiquette authentique.
