Abstract

La présente invention vise à proposer un dispositif d'authentification (5) qui peut définir une zone dans laquelle l'authentification d'un utilisateur (3) possédant un dispositif intelligent (4) peut être effectuée de manière stable, et le dispositif intelligent (4) correspondant au dispositif d'authentification (5), ainsi qu'à proposer un système d'authentification (1), un système de gestion d'accès à une pièce, un système de gestion de répartition d'ascenseur, et un système de positionnement dans lesquels le dispositif d'authentification (5) et le dispositif intelligent (4) sont utilisés. Le dispositif intelligent (4) possédé par l'utilisateur (3) a un capteur magnétique (13) monté. Le dispositif d'authentification (5) comprend un champ magnétique fluctuant ayant une intensité d'une valeur de seuil ou supérieure formé sur la totalité de l'intérieur d'une zone de collationnement (7). Lorsque le capteur magnétique (13) détecte le champ magnétique fluctuant ayant une intensité de la valeur de seuil ou supérieure, et qu'un signal sans fil envoyé par le dispositif intelligent (4) est reçu, le dispositif d'authentification (5) authentifie l'utilisateur (3) sur la base des informations de collationnement.
