Abstract

L'invention concerne un procédé et un appareil pour vérifier l'authenticité d'un document émis au moyen d'un code à barres, en imprimant une adresse d'un serveur de vérification en tant que code à barres sur le document émis pour vérifier l'authenticité du document émis, et en important immédiatement et en affichant un fichier de copie du document émis lorsqu'une image de code à barres est capturée par un appareil photographique d'un terminal mobile. Le procédé comprend : (a) une étape à laquelle le terminal mobile capture l'image du code à barres imprimé sur le document émis, et entre l'image ; (b) une étape à laquelle le terminal mobile extrait de l'image de code à barres l'adresse du serveur de vérification et les informations d'authentification du document émis ; c) une étape à laquelle le terminal mobile transmet les informations d'authentification du document émis à l'adresse extraite du serveur de vérification et effectue une demande d'un fichier de copie du document émis ; (d) une étape à laquelle le serveur de vérification authentifie les informations d'authentification reçues du document émis et transmet le fichier de copie du document émis au terminal mobile ; et (e) une étape à laquelle le terminal mobile reçoit le fichier de copie et affiche le fichier de copie reçu sur son écran au moyen d'une visionneuse de document émis installée dans le terminal mobile. Selon le procédé et l'appareil décrits ci-dessus de la présente invention, le code à barres dans lequel l'adresse du serveur de vérification est encodée, est lu pour accéder au serveur de vérification, éliminant de ce fait la nécessité d'entrer l'adresse du serveur de vérification pour vérifier l'authenticité de documents émis, et permettant la vérification rapide et commode d'un grand volume de documents émis.
