Abstract

L'invention concerne un procédé et un dispositif de vérification d'éléments de sécurité de documents de valeur, par exemple des billets de banque, des cartes d'identité, des cartes de paiement ou similaires. L'invention concerne en outre un procédé et un dispositif de vérification d'objets qui présentent un écran, par exemple un ordinateur, un notebook ou un ordinateur portable, la caisse d'un système de caisse ou un appareil manuel. Selon l'invention, une première information est disposée dans au moins une partie translucide d'un élément de sécurité. Selon l'invention, au moins une partie de l'affichage présente une deuxième information. Dans la première information, la deuxième information ou dans les deux informations est incorporée une autre information qui ne peut être simplement détectée et/ou lue sans accessoires par un observateur. Pour vérifier les objets de valeur dotés d'un écran, on utilise selon l'invention un élément de vérification qui présente au moins un substrat doté d'au moins une partie transparente, une première information étant disposée dans la ou les parties transparentes du substrat. Selon l'invention, on effectue une vérification de l'élément de sécurité ou de l'objet de valeur en plaçant la première information prévue dans la partie translucide de l'élément de sécurité ou de l'élément de vérification au-dessus de la deuxième information, ce qui rend détectable et/ou lisible l'information incorporée sous la forme d'un motif moiré et/ou de métamères.
