Abstract

L'invention divulgue un procédé de lecture d'un code de sécurité d'hologramme. Ce procédé comprend les étapes consistant à : acquérir une pluralité d'images d'hologramme par balayage du code de sécurité d'hologramme par une caméra d'un terminal utilisateur ; restaurer, par un processeur du terminal utilisateur, un code de sécurité d'origine par combinaison des images de la pluralité d'images d'hologramme ; et lire le code de sécurité d'origine par le processeur.
