Authentication method, authentication system, and authentication token

摘要

An authentication method includes the first, second, and third steps. In the first step, a biometrical information sensor reads the biometrical information of a user. In the second step, the read biometrical information is collated with registered biometrical information in a registration memory. When the collation result represents that collation has successfully been done, user unique information from an authentication information output section is converted into an emulator signal corresponding to a service provided by a use device. The emulator signal is transmitted to the use device. In the third step, the use device provides the service to the user on the basis of the received emulator signal. An authentication system and authentication token are also disclosed.
