PROBLEM TO BE SOLVED: To improve accuracy of personal authentication without increasing time and labor of a user for authentication.SOLUTION: A user performs authentication input into an authentication input device 10. A transmitter 20 associated with the authentication input device 10 transmits a signal ID for specifying the authentication input device 10. When a program preset to a mobile terminal 40 possessed by the user receives the signal ID via a communication function of the mobile terminal 40, the program transmits terminal side information data consisting of the signal ID and a terminal side specification ID preset as an ID for specifying the user to a server 50. The server 50 verifies whether information on user specification for specifying the user corresponding to the authentication input performed at the authentication input device 10 specified by the received signal ID corresponds to the received terminal side specification ID, transmits the verification result, and determines personal confirmation from determination by the authentication input and the verification result transmitted by a verification result transmission unit.SELECTED DRAWING: Figure 1 |
