Abstract

Only users registered beforehand in a network are able to obtain access to the network while maintaining strict security. Living-body authentication information for living-body authentication of a user 1A and access authentication information required for access to a network determined for each user are stored on the memory region of an electronic circuit mounted on a disk (or on an external storage medium). When the disk is driven, living-body authentication information is acquired from the user by living-body authentication means 11E. The living-body authentication information is compared with the living-body authentication information stored in the electronic circuit (or the external storage medium). When both are the same, the access authentication information stored in the electronic circuit (or the external storage medium) is sent to the network. Based on the received access authentication information, the network decides whether the user is a regular user and, when the user is decided to be a regular user, allows the connection of the user terminal with a service community.
