In a biometrics system for a building entrance unlocking or a bank account authentication, reference information registered under administration by the system is transmitted to a room or mobile-phone for private storage, with the original reference information deleted from the system. Biologic information gotten upon authentication is transmitted through wireless system to the room or mobile-phone for comparison with the reference, the result being returned to the system. Or, the reference is tentatively sent back to the system for comparison with the gotten biologic information. The biologic information sent to mobile-phone also includes health control information for storage and display. Mobile-phone also can receive blood pressure information at a waiting lounge of medical institution though wireless local communication even if the main power shut down. The communication between the biometrics system and the mobile-phone is encrypted. The system includes sensor unit and protection unit, the abnormality thereof being separately checked.
