Biometric authentication system, biometric authentication processing device, biometric authentication method, biometric information acquisition terminal, and information terminal

摘要

Provided is a highly-secure yet convenient 1:N biometric authentication system achieved by a biometric authentication method using a combination of wireless communication by an information terminal, such as a smartphone, and biometric information acquired by a biometric information acquisition terminal. Specifically, provided is a biometric authentication system including an information terminal that has ID information, a biometric information acquisition terminal that acquires biometric information, and a biometric authentication processing apparatus. The biometric authentication processing apparatus includes: a first communication part that communicates with the information terminal and thereby acquires the ID information and location information on the information terminal; a second communication part that communicates with the biometric information acquisition terminal and thereby acquires the biometric information; a location information storage part that stores therein an indication that the information terminal having the ID information and the biometric information acquisition terminal are located within a predetermined range; a biometric reference information storage part that associates and stores the ID information and biometric reference information to be used for comparison in biometric authentication; and a control part that controls these parts. The control part controls the following operations: acquiring the ID information on the information terminal and the location information indicating a location of the information terminal using the first communication part, when the location information indicates that the information terminal is within the predetermined range from a location of the biometric information acquisition terminal, storing, in the location information storage part, an indication that the information terminal and the biometric information acquisition terminal are located within the predetermined range, and upon acquisition of the biometric information from the second communication part, performing a comparison process on the biometric information using the biometric reference information stored in the location information storage part in association with the ID information on the information terminal.
