Biometric matching system, biometric matching method, biometric matching device and control program

摘要

To provide a biometric matching system capable of appropriately performing verification of biometric information while improving user's convenience.SOLUTION: The biometric matching system 1 includes a plurality of mobile terminals 100 and a biometric matching device 200. The biometric matching device 200 has a storage unit, an acquisition unit, a reception unit, an extraction unit, and a collation unit. The storage unit stores the registebiometric image of the user of each portable terminal in association with the identification information of each portable terminal. The acquiring unit acquires input biometric information of a specific user. The receiving unit receives a position signal or a radio signal from each portable terminal. Based on the received position signal or wireless signal, the extraction unit detects two or more mobile terminals within a ptermined range from the biometric matching device, extracts, from the registebiometric images stoin the storage unit, the detected mobile terminal Two or more registebiometric images respectively associated with the identification information of the registebiological images. The collation unit collates each input biometric information with the extracted registebiometric image.BACKGROUND OF THE INVENTION
