Abstract
Cet élément d'information (10) comprend un matériau (20-22) résistant à la séparation, déposé sur une partie de la surface de l'élément (10), et une couche réceptrice (30) d'informations recouvrant au moins une partie de ce matériau (20-22) et une partie de cette surface. La couche réceptrice est conçue pour recevoir des informations. Un ruban transparent (50), fixé par collage sur cette couche (30) réceptrice portant des informations, adhère plus fortement sur cette couche (30) que celle-ci n'adhère sur le matériau (20-22) résistant à la séparation. Ainsi, l'enlèvement du ruban transparent (50) du dispositif enlève aussi bien la couche (30) réceptrice d'informations que les informations (40) superposées au matériau (20-22) résistant à la séparation du reste de la couche réceptrice d'informations et des informations restantes, ce qui permet la détection visuelle facile d'une manipulation non autorisée. On décrit aussi un procédé d'utilisation associé.
