Abstract

TITRE DE L’INVENTION : PROCEDE ET DISPOSITIF D’AUTHENTIFICATION DE CODES IMPRIMES Le procédé (70) d’association d’une signature d’authentification à un code imprimé comportant des points imprimés comporte :- une étape (71) de capture d’une image du code imprimé,- une étape (72) de repérage, dans l’image captée, d’éléments géométriques caractéristiques d’une norme d’impression du code imprimé,- une étape (73) d’estimation de déformations et de rotation dues à la perspective à la position de capture de l’image, pour repérer chaque point du code dans une cellule du code capté,procédé caractérisé en ce qu’il comporte, de plus :- une étape (74) d’extraction, dans l’image captée, d’un contour d’au moins un point imprimé dans une cellule prédéterminée du code capté,- une étape (75) de mesure d’une pluralité de dimensions géométriques représentatives d’au moins un contour extrait, et- une étape (76) de constitution d’une signature du code en fonction des dimensions géométriques extraites.
