Abstract

L'invention concerne un document d'identification présentant deux images superposées ainsi qu'un procédé de fabrication d'un document d'identification. En outre, l'invention concerne un procédé de vérification de l'authenticité d'un tel document d'identification. L'invention vise à améliorer la protection de tels documents d'identification, munis d'une image en couleur, contre toute falsification ou manipulation. A cet effet, les images sont appliquées au cours d'étapes de travail distinctes, au moins une des images se présentant sous une forme non accessible depuis l'extérieur, une des images étant une image à niveaux de gris et une des images étant une image en couleur qui contient à la fois des informations de couleur et des informations d'intensité.
