  • biometric authentication is OK when the matching degree AT in the entire area reaches a predetermined value (80%) or more by 60 seconds after the start of the “authentication support mode” (S1307: YES) It is determined that (the biometric authentication is successful), and the main control unit 100 performs the transaction process as the “normal transaction” (withdrawable limit: 3,000,000 yen / day) (S1308 to S1309).
  • the main control unit 110 confirms whether the coincidence degree AT in the entire area is 65% or more (S1322), and is less than 65% In the case (S1322: NO), the processing after S1315 is performed. That is, the control unit 110 displays on the display 103 that it can not expect cancellation of the lack of coincidence due to a temporary factor of the user of the user, and holds the identification document 201b presented by the user at the time of registration of biometric information.
  • the identity verification material 201b If the identity verification material 201b is brought in, whether it matches the information 509 such as the classification of the identity verification material 201b and the personal identification number recorded in the IC chip 301a in the IC card 201a And, depending on the result, shift to "Restricted Transaction 1" or "Restricted Transaction 2".
  • the main control unit 110 forgets the setting method of the finger 801 at the time of registration of biometric information, or is registered in an inappropriate state It is displayed on the display 103 that it can not expect cancellation of lack of coincidence due to permanent cause of registration failure (S1323).
  • the biometric information is not re-registered, it is not possible to process the “normal transaction” with the withdrawal limit being high (3 million yen / day). Therefore, after confirming the presentation of the identification document 201b, it is possible to re-register biometric information.
  • the “authentication support mode” it is limited to the case where it can not be judged as the personal factor in S 1314 and the coincidence degree AT in the whole area is not large but is insufficient (50% or more and less than 65%). Enables re-registration of biometric information as a special response. In addition, it is a case when it is not judged that it is an individual factor in S1314, and the re-registration of biological information is permitted when the coincidence degree AT in the whole area is largely lacking (50% or more and less than 65%). The reason why the degree of coincidence AT in the whole area is low is judged as the principal factor.
  • the main control unit 110 displays on the display 103 a screen (not shown) for confirming whether the user 202 has the personal identification material 201b presented at the time of registration of the biometric information.
  • the identity verification document 201b is not brought (S1324: NO)
  • the withdrawal limit is low ("Restriction transaction 1" (withdrawal limit: 100,000 yen / day or 300,000 yen / day)) (S1325) ).
  • the main control unit 110 guides the user to hold the contactless IC reader 109.
  • the main control unit 110 reads the classification and the personal identification number from the IC chip 301b of the identification document 201b by the non-contact IC reader 109 (S1326), and the identification document recorded in the IC chip 301a in the IC card 201a. It is compared and collated whether it matches the information 509 such as the classification of 201b and the personal identification number (S1327). As a result of comparison and collation, when the classification and personal identification number do not match (S1327: NO), the "limit transaction 1" (withdrawal limit: 100,000 yen / day or 300,000 yen / day) with a low withdrawal limit To step S1325.
  • the main control unit 110 displays a screen (not shown) for confirming to the user 202 whether or not to re-register biometric information on the display Do.
  • the user 202 sets a finger on the finger vein reader 102 (S1330).
  • the registration data 505 of the IC chip 301a the registration data already recorded in the new registration data 505a is moved to the old registration data 505b, and the biometric information read by the finger vein reader 102 is newly registered data. It is stored in 505a.
  • the main control unit 100 performs transaction processing as "normal transaction" (withdrawal limit: 3,000,000 yen / day) (S1331).
  • the main control unit 100 performs the transaction process as "restricted transaction 2" (withdrawable limit: 1,000,000 yen / day) (S1329).
  • the biometric information is registered and authenticated by the finger vein reader 102 mounted on the ATM 101, but the biometric information is not limited to finger veins, and may be palm vein, fingerprint, iris, face image, etc. Other biometric information may be used.
  • the biological information is recorded in the IC chip 301a mounted in the IC card 201a, but the biological information is registered in the IC chip mounted in the portable terminal (eg, a mobile phone)
  • the same process may be performed by reading the terminal with the noncontact IC reader 109.
  • you may perform centralized management of biometric information by registering biometric information in the server of a financial institution.
  • the cause of the lack of the matching degree AT in the entire area is determined from the feature of the finger vein image recorded in the IC chip 301a of the IC card 201a and the matching degree AT of the biological information. You may judge using history etc.
  • the upper limit of the withdrawal amount is limited as an example of the limited transaction, the type of transaction may be limited (for example, the withdrawal transaction may be limited) or the number of transactions per day may be limited. good.
  • the instruction from the main control unit 110 to the user 202 uses the display 103 of the ATM 101 and voice guidance.
  • the biometric information registration device, the biometric authentication personal computer, or the biometric information authentication device If a liquid crystal display or the like is mounted on its own, the user 202 may be instructed using these devices. Therefore, the present invention is not limited to the ATM, and can be applied to a general information processing apparatus including a biometric information registration apparatus, a personal computer with biometric authentication, a biometric information authentication apparatus, and an automatic machine. In this case, similar biometric authentication can be performed not only on the biometric information of the user who uses the automatic machine, but also on the biometric information of the operator (customer or clerk) who operates the automatic machine. .
