Abstract

L'invention concerne un procédé et un dispositif qui permettent à un utilisateur d'accéder à une ressource à l'aide d'un appareil terminal mobile par l'intermédiaire d'un réseau, en particulier de l'Internet, cet accès étant contrôlé par un serveur qui peut déterminer de manière fiable si l'appareil terminal mobile se trouve à l'instant approximatif de la vérification à proximité d'un mécanisme de codage. L'identité de la ressource et celle du serveur sont déterminées par le mécanisme de codage susmentionné, l'appareil terminal mobile ne doit pas être réglé manuellement sur la ressource concrète. Le mécanisme de codage établit pour cela des enregistrements de données d'accès (par exemple sous forme d'adresses URL) qui identifient les ressources, comportent une référence temporelle et une signature numérique. Ces enregistrements de données sont envoyés par une liaison de données locale (par exemple une communication de type NFC) à l'appareil terminal mobile qui les traite de préférence automatiquement et peut ainsi accéder à la ressource, le serveur vérifiant la signature et la proximité temporelle à l'aide desquelles il contrôle l'accès.
