Abstract

Procédé pour vérifier un contenu affiché par un dispositif d’affichage numérique (1) comprenant une unité centrale, un écran numérique (3) commandé par l’unité centrale et des capteurs optiques (4) adaptés pour prendre des séquences d’images partielles de l’écran numérique. On calcule automatiquement une première signature de chaque séquence d’images et une deuxième signature à partir des signatures des différentes séquences d’images du même contenu. On transmet la deuxième signature à un serveur (5) distant qui compare la deuxième signature avec une signature similaire calculée à partir d’un contenu planifié prévu pour être affiché sur l’écran numérique et, si la deuxième signature correspond à la signature du contenu planifié, on génère un jeton authentifiant le contenu affiché.[Fig. 1]
