Abstract
La présente invention porte sur un procédé d'authentification d'informations numériques qui consiste à : obtenir, sous forme numérique, des informations en vue d'une authentification; préparer les informations en vue d'un traitement, une telle préparation comprenant la conversion des informations en une image numérique; identifier des segments de contenu dans l'image numérique; regrouper les segments de contenu en un ou plusieurs groupes de segments; générer une séquence de marquage comprenant le déplacement d'au moins un groupe parmi les un ou plusieurs groupes de segments dans une ou plusieurs directions; et appliquer la séquence de marquage à l'image numérique, créant ainsi une copie marquée unique de l'image numérique.
