Authentication token and authentication system

摘要

An authentication token includes a personal collation unit and communication unit. The personal collation unit includes a sensor, storage unit, and collation unit. The sensor detects biometrical information of a user and outputs the detection result as sensing data. The storage unit stores in advance registered data to be collated with the biometrical information of the user. The collation unit collates the registered data with the sensing data and outputs the collation result as authentication data. The communication unit transmits the authentication data from the personal collation unit to the use device as communication data. The personal collation unit and communication unit are integrated.
