  • the fourth embodiment is different from the information processing system except that the wearable terminal 10 combines and displays the image captured by the camera 32 and the display image by the remote access server 22 and records the captured image of the camera 32.
  • the basic configuration and operation of the wearable terminal 10 are the same as those in the first embodiment.

Abstract

L'invention concerne une technologie conçue pour accroître l'intégrité des informations dans un système de traitement d'informations qui permet un accès à distance. Le terminal portatif ci-décrit, qui est monté sur la tête d'un utilisateur, comporte : une unité de lecture qui acquiert une image d'informations biologiques obtenue par photographie d'un œil de l'utilisateur ; une unité de projection qui est placée à demeure sur l'unité de lecture et qui projette une image à afficher sur un trajet optique différent du trajet optique sur lequel l'unité de lecture acquiert l'image d'informations biologiques ; une unité de communication qui communique avec un serveur d'accès à distance ; et une unité de traitement qui effectue une authentification d'utilisateur sur la base de l'image d'informations biologiques et qui accède, lorsqu'un résultat d'authentification positif est obtenu, au serveur d'accès à distance par l'intermédiaire de l'unité de communication.
