Abstract
(EN)
The present invention relates to a document authentication system and a document authentication method having an enhanced authentication function by an inquiry history notice. The present invention enables easy identification of whether a document is authentic, forged, or tampered, by means of document authentication information registered by a document issuer and also enables the document issuer to be notified of an inquiry history of a document inquirer so that an indiscriminate leak of a document can be prevented, thereby further enhancing a document authentication function.
(FR)
La présente invention concerne un système d'authentification de document et un procédé d'authentification de document ayant une fonction d'authentification améliorée par une notification d'historique d'interrogation. La présente invention permet une identification facile du fait qu'un document est authentique, falsifié ou altéré, au moyen d'informations d'authentification de document enregistrées par un émetteur de document et permet également à l'émetteur de document d'être notifié d'un historique d'interrogation d'un demandeur de document de telle sorte qu'une fuite indifférenciée d'un document peut être évitée, ce qui permet d'améliorer davantage une fonction d'authentification de document.
