A user brings this mobile communication terminal to a service area and causes an image of his own biometrics information to be captured, and this biometrics data and an account number are stored in a common area of the mobile communication terminal. Therefore, the mobile communication terminal has functions of an individual card storing biometrics information, and issuing of a card for use in biometrics authentication is completed.

## Background
CROSS-REFERENCE TO RELATED APPLICATIONS
This application is based upon and claims the benefit of priority from the prior Japanese Patent Application No. 2005-193127, filed on Jun. 30, 2005, the entire contents of which are incorporated herein by reference.
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a biometrics authentication method and biometrics authentication system to detect characteristics of the body and perform individual authentication, and in particular relates to a biometrics authentication method in which biometrics authentication functions are installed in a mobile communication device to perform biometrics authentication, and a biometrics authentication system which uses a mobile communication device.
2. Description of the Related Art
With advances in information processing technology in recent years, various illicit transactions using electronic data have become prominent. In particular, with the widespread practice of authentication of individuals using a card with a password, the relation between card data and passwords has become widely known, and there have been conspicuous instances of the illicit acquisition of card data and passwords, the damage resulting from which has been considerable.
As one method to resolve such problems with methods involving passwords, various technologies have been proposed for biometrics authentication utilizing characteristics of the human body. For example, methods employing fingerprints, the iris of the eye, facial features, blood vessel images (in the palm of the hand and the fingers), and similar have been proposed. In such biometrics authentication technologies, an individual's own biometrics characteristic data is registered on the individual's card. In order to employ biometrics authentication to enable transactions, a biometrics information reader provided in the transaction equipment which acquires biometrics information is used to acquire biometrics information for the individual, the acquired biometrics information is compared with the registered biometrics data on the individual's card, and depending on the comparison result, the transaction is permitted (see for example Japanese Patent Laid-open No. 2001-067523).
However, when using the technology of the prior art, various procedures are necessary to issue an individual card for biometrics authentication, from application by the user to issuing of the card, so that time is required. Further, when numerous individual cards for biometrics authentication are issued at a service area, security measures must be considered, entailing additional labor. And because issuing of an individual card is a burden placed on the issuing party, costs are incurred in issuing cards, and these costs have also acted to impede widespread adoption.
Thus although biometrics authentication technology is an extremely effective measure to prevent illicit transactions, the process for securely issuing identification cards is complex, and moreover costs are incurred when issuing cards, thus impeding widespread adoption.

Below, embodiments of the invention are explained in the order of a biometrics authentication system, processing for registration in a mobile communication device, processing during use of a mobile communication device, and other embodiments. However, this invention is not limited to these embodiments.
Biometrics Authentication System
FIG. 1 shows the configuration of the biometrics authentication system of one embodiment of the invention; FIG. 2 shows the configuration of a mobile communication device to which the biometrics authentication functions of FIG. 1 have been imparted; FIG. 3 shows the configuration of the service area device of FIG. 1; and FIG. 4 shows the configuration of the automated transaction device of FIG. 1. The biometrics authentication system of FIG. 1 is an example of a financial system employing an ATM (Automated Teller Machine) in use by financial organizations.
As shown in FIG. 1, the mobile communication terminal 1 is configured as a portable telephone having functions for contact-free IC card data reading and writing. As explained below using FIG. 2, as this portable telephone, for example, a Felica (a registered trademark)-compatible portable phone is suitable. For example, the F901i (manufactured by Fujitsu Ltd.) of NTT DoCoMo is equipped with FeliCa-compatible i-applications.
A Felica-compatible terminal 2 is configured as automated transaction equipment, explained in FIG. 4. The i-application server 3 communicates with the mobile communication terminal 1 by e-mail, and in response to access by the mobile communication terminal 1, secures a common area for the i-application on the mobile communication terminal 1, and transmits the biometrics authentication application. The bank host 5 is connected to the Felica-compatible terminal 2, and executes transaction processing based on biometrics authentication using the mobile communication terminal 1.
A service area terminal 6A, connected to a biometrics image capture device 10 and a Felica reader/writer 21, is provided in a branch 6 of the financial organization. This biometrics image capture device 10 acquires vein data (for example, of the veins in the palm of the hand or fingers) from the human body as biometrics information. The Felica reader/writer 21 communicates with a Felica chip in the mobile communication terminal 1 to read and write data from and to the mobile communication terminal 1. The service terminal 6A appends an account number and similar to the acquired biometrics information, and registers this information in the mobile communication terminal 1. This service area terminal 6A is connected to the bank host 5 and executes the registration processing.
As shown in FIG. 2, the above-described mobile terminal 1 has a display unit 13, key input unit 14, long-range communication unit (mobile communication unit) 15, CPU 11, memory 12, short-range communication unit (FeliCa chip) 16 with contact-free IC card specifications, and a bus 17 connecting these.
This mobile terminal 1 has mail functions, including a browser, voice phone functions, i-application execution functions, and contact-free IC card functions. The CPU 11 starts these functions in response to key operation of the key input unit 14. Further, the memory 12 has an i-mode (a registered trademark) application program area 12-1, and a common area 12-2 to store an account number for transactions and biometrics information and similar. This common area 12-2 is an authenticated area which can be used by the Felica chip 16, and as explained below, is allocated as an area for use by a biometrics authentication application as a result of request for Felica use.
The service area terminal 6A in FIG. 1 has, as hardware, a CPU unit, keyboard, and display. The service area terminal 6A is connected to a vein sensor 10 as the biometrics image capture unit, and to a Felica reader/writer 21, including an antenna 21A for wireless communication with the Felica chip 16 in the mobile communication terminal 1 and an RF (Radio Frequency) unit 21B.
As shown in FIG. 3, as software the service area terminal 6A further has a Windows (a registered trademark) or other OS (Operating System) 60; a service area processing application 61; package software 62; and middleware 63. The service area terminal 6A further has a vein authentication driver 67 which drives the biometrics image capture unit 10, which here is a vein sensor; a vein authentication library (program) 66, which performs vein authentication processing; a Felica R/W driver 65, which drives the Felica reader/writer 21; and a Felica library (program) 64, which performs processing of data from a Felica chip 16.
As shown in FIG. 4, the automated transaction equipment 2 has a control unit 20, memory (magnetic disk device) 22, customer operation unit 23, card unit 24, cash unit 25, circuit line control unit 26, and biometrics image capture unit 10 (here, a vein sensor). The card unit 24 reads a magnetic card/IC card inserted from a card insertion/ejection aperture (not shown), and returns the card to the insertion/ejection aperture. Further, the card unit 24 optically reads the card (embossed portion) by means of an image sensor. The card unit 24 uses a printing head to print the results of the transaction on a receipt form, and ejects the printed receipt through the card insertion/ejection aperture.
The UOP unit (customer operation unit) 23 includes a display with touch-screen (screen display unit 23-1 and touch-panel for key input 23-2) 23-1, 23-2, a voice guidance unit 23-3, and a customer sensor 23-4.
The cash unit 25 includes a recycling-type paper currency/coin withdrawal/deposit mechanism, which has a paper currency/coin quantity counting portion which validates and counts paper currency/coin inserted from the paper currency/coin insertion/ejection opening; a paper currency storage portion (stacker) to store paper currency/coins; and a unit control portion to perform deposit operations to store counted paper currency/coins in the stacker, and withdrawal operations to pick up the required paper currency/coins from the stacker and discharge the paper currency/coins to the paper currency/coin insertion/ejection opening.
The circuit line control unit 26 exchanges data with the host computer 5 (host of the financial organization) via public circuits or similar 4. The control unit 20 uses programs and data in the memory 22 to control the customer operation unit 23, card unit 24, cash unit 25, and circuit line control unit 26.
Further, the automated transaction equipment 2 has a mobile communication unit 21 which communicates with the mobile communication terminal 1. This mobile communication unit 21 includes the contact-free IC card reader/writer 21 explained in FIG. 3, and is connected to the control unit 20. The software 60 to 67 explained in FIG. 3 is installed in the control unit 20.
In this invention, as indicated in FIG. 1, the vein application is downloaded to the mobile communication terminal 1 from the i-application server 3, and an authenticated biometrics information area is created. The user brings the mobile communication terminal 1 to the service area 6, causes his own biometrics information to be captured in an image, and stores the biometrics data (vein data) and an account number in the common area 12-2 of the mobile communication terminal 1. By this means, the mobile communication terminal 1 has the functions of an individual card storing biometrics information, and issuing of a card for biometrics authentication is completed.
The user causes the mobile communication terminal 1 to be read by the automated transaction equipment 2, performs individual authentication based on biometrics authentication, and executes an automated transaction from the account. Consequently the process of card issuing is simplified, the costs incurred in card issuing can be reduced, and biometrics authentication can be performed.
Processing for Registration in a Mobile Communication Device
FIG. 5 shows the flow of the registration processing in the mobile communication terminal of an embodiment of the invention; FIG. 6 explains this registration processing. As indicated in FIG. 5, the i-application server 3 includes an i-mode server 3A, i-application download server 3B, and Felica-compatible server 3C. First, the vein authentication application is registered in i-application download menu of the i-mode (registered trademark), and a common area 12-2 is secured in the Felica chip 16.
That is, a request is submitted to a service company operating the Felica network, a specific area is allocated in the common area 12-2, and a vein authentication application ID (identifier) is obtained. The Felica service company stores the allocated ID, area, and registration data necessary for initialization on the Felica-compatible server 3C. Further, the vein application is registered as an i-application download menu of the i-mode server 3A.
As indicated in FIG. 5, the user uses an i-mode browser 18 on the mobile communication terminal 1 to access the home page of the i-mode server 3A, thereby the vein authentication application site can be selected as an i-application.
As shown in FIG. 6, the user operates the mobile communication terminal 1 to connect to the download site (i-application download server) 3B for the vein authentication application, then a message indicating connection to the site is displayed on the screen of the display unit 13 of the mobile communication terminal 1. The user operates keys 14 on the mobile communication terminal 1 to cause the vein authentication application to be downloaded to the mobile communication terminal 1 from the i-application server 3B, and the application is stored in the memory 12.
Next, when the user starts the vein authentication application which has been downloaded to the mobile communication terminal 1, connection is made to the Felica-compatible server 3C using an URL embedded in the vein authentication application. The Felica-compatible server 3C transmits to the mobile communication terminal 1 various types of information for registration in the Felica chip 16 (which includes memory 12), according to the above-described allocated ID sent from the mobile communication terminal 1.
The mobile communication terminal 1 receives this, creates a vein authentication service area in the common area 12-2, and registers this area in the Felica chip 16. For example, a screen for the process of creation of a palm vein area such as shown in FIG. 6 is displayed on the display portion 13 of the mobile communication terminal 1, and as indicated in FIG. 5, a vein authentication service area (account area and biometrics information area) is created in the common area 12-2.
Here the palm vein authentication application limits access to areas by means of mutual authentication via the Felica reader/writer 21, and in addition performs reading and writing of the allocated vein authentication service area according to instructions after authentication. Moreover, there is also a function to perform processing as necessary to compare the biometrics information (vein data) registered in the biometrics information area of the common area, described below, with the biometrics information obtained via the Felica reader/writer 21, to perform biometrics authentication.
In this way, the vein authentication application is downloaded from the communication site to the mobile communication terminal 1, and a service area is created in the Felica chip. Access to this service area is limited by the vein authentication application, so that security functions can be provided, and the mobile communication terminal 1 can be provided with the functions of biometrics authentication media. Hence advance preparations to issue a card for biometrics authentication are possible anywhere and at any time, according to operations by the user.
Processing During use of a Mobile Communication Terminal
Next, processing during use of a mobile communication terminal is explained, using FIG. 7 through FIG. 10. FIG. 7 shows the flow of biometrics data registration processing and biometrics authentication processing of the mobile communication terminal of an embodiment of the invention, and FIG. 8 explains the biometrics data registration processing.
First, biometrics data registration processing is explained. As shown in FIG. 1, a user carries a mobile communication terminal 1 in which is registered the above-described vein application, and comes to the service area 6 of the bank. As indicated in FIG. 8, the user employs a prescribed form or similar to request an account transaction by portable telephone at the service area 6. At the service area 6, a bank host 5 is queried, and the identity of the individual is verified. For example, the user may fill in a form with his name, date of birth, address, phone number, portable phone number, account number, seal or password number, and similar, and present the form to the service area personnel. At the service area, the bank host 5 is queried using this information, to determine whether the individual is in fact the owner of the account with this information. The portable phone number is confirmed while at the service area.
Upon confirmation of his identity, the user places his portable phone with contact-free IC functions (for example, Felica functions) 1 over the Felica reader/writer 21 of the service area terminal 6A. The service area terminal 6A uses the Felica library 64 to authenticate and be authenticated by the portable phone 1, and when the result of the mutual authentication is satisfactory, the i-application of the portable phone 1 is started. As indicated in FIG. 7, by this means the vein authentication application of the portable phone 1 is started. A selection screen titled “XX Bank ATM-capable Cell Phone” shown in FIG. 8 is displayed on the display unit 13 of the portable phone 1. Here, “Cash card transaction”, “Registered account balance”, and “Biometrics registration” are displayed on the selection menu.
When the user selects “Biometrics registration” on this screen, the “Please place the cell phone over the sensor” guidance screen in FIG. 8 is displayed on the display unit 13 of the portable phone 1. At this screen, cancellation of the selected item can be selected.
On the other hand, a “Vein pattern registration using cell phone” screen G1 in FIG. 8 is displayed on the service area terminal 6A in response to selection of biometrics registration. At this screen G1, “Registration” and “Inquiry” can be selected. When the user selects registration at this screen G1, the “Please place the cell phone over the sensor” guidance screen G2 in FIG. 8 is displayed. At this screen, cancellation of the selected item can be selected.
Next, the account confirmation screen G3 is displayed at the service area terminal 6A. This screen G3 displays the account number and individual information previously verified for the individual. At this screen G3, upon pressing a “Confirm” button, the service terminal 6A displays the palm vein pattern reading guidance screen G4. In response, the user extends his palm over the vein sensor 10. The vein sensor 10 reads an image of the veins in the palm of the hand, and sends the read image to the vein authentication library 66 of the service area terminal 6A. The vein authentication library 66 extracts vein pattern characteristics from the vein image, and creates biometrics data (vein data).
Further, the service area terminal 6A writes this vein data and the account data and similar to the common area 12-2 managed by the vein authentication application of the portable phone 1 using the Felica reader/writer 21, via the Felica library 64. Test authentication is then performed. That is, the service area terminal 6A again displays a guidance screen G5 for reading of the vein pattern in the palm of the hand. In response, the user extends the palm of his hand over the vein sensor 10. The vein sensor 10 reads the vein image of the palm, and sends this to the vein authentication library 66 of the service area terminal 6A. The vein authentication library 66 extracts the vein pattern characteristics from the vein image, and creates biometrics data (vein data).
On the other hand, the service area terminal 6A uses the Felica reader/writer 21 to read vein data registered in the common area 12-2 of the portable phone 1 via the Felica library 64, and uses the vein authentication library 66 to verify the re-read vein data against the registered vein data to confirm verification. Or, the vein data thus read is sent to the vein authentication application of the portable phone, and verification confirmation is performed within the phone. If the verification result is satisfactory, the service area terminal 6A displays a registration completion screen G6, and a registration completion screen is also displayed on the display unit 13 of the portable phone 1.
Upon this completion of registration, as shown in FIG. 7, the vein authentication application of the portable phone 1 notifies the Felica-compatible server 5A of the financial organization, via the mobile communication network 8, of registration of biometrics information. That is, the account information and registration information are stored in the Felica-compatible server 5A.
In this way, biometrics information is registered in the portable phone 1, and transactions based on biometrics authentication are made possible.
Next, FIG. 9 and FIG. 10 are used to explain biometrics authentication processing.
(S10) As shown in FIG. 10, when the user presses an i-application key using the key input unit 14 of the mobile terminal 1, the CPU 11 starts the i-application, and an i-application wait screen is displayed on the display unit 13. Also, the automated transaction equipment 2 displays, on the customer operation unit 23 as the transaction selection screen G10, the selection icons “Deposit”, “Withdrawal”, “Balance inquiry” and “Bankbook recording”, which are normal card transactions, as well as “Transaction using cell phone”, which is a transaction using the portable phone.
(S12) When the user selects “Transaction using cell phone” at the displayed transaction selection screen G10, the automated transaction equipment 2 displays a guidance screen G11 on the customer operation unit 23 instructing the user to place the portable phone over the Felica sensor 21. The user places the short-range communication unit 16 of the portable phone 1 over the mobile communication unit 21 of the ATM 2, whereupon the above-described account number, biometrics information and similar is communicated by contact-free means to the mobile communication unit 21 of the ATM 2 from the short-range communication unit 16, by a well-known read/write sequence of a contact-free IC card. Upon receiving this, the ATM 2 displays the account selection screen G12 on the customer operation unit 23. This account selection screen G12 provides the account numbers transmitted from the portable phone 1. The user selects the account number for the transaction from the customer operation unit 23, whereupon a portable phone transaction selection screen G13 is displayed on the customer operation unit 23. This transaction selection screen G13 displays only those transactions which can be performed automatically using the portable phone 1. Here, only “Withdrawal”, “Deposit”, and “Balance inquiry” can be selected.
(S14) When the user selects a transaction item using the customer operation portion 23, the ATM 2 displays a palm vein reading guidance screen G14 on the customer operation unit 23. In response, the user extends the palm of his hand over the vein sensor 10. The vein sensor 10 reads the vein image of the palm, and sends the data to the vein authentication library 66 of the ATM 2. The vein authentication library 66 extracts the vein pattern characteristics from the vein image, and creates biometrics data (vein data). The vein authentication library 66 of the ATM 2 then verifies the read-out vein data against the vein data registered in the portable phone 1, and confirms verification. If the authentication fails (is unsuccessful), a retry operation is performed; if authentication is not successful even after a prescribed number of retries, the service processing ends, and blockage of service processing is performed.
(S16) If on the other hand the authentication is successful, the ATM 2 judges the transaction selection made in step S12 using the portable phone.
(S18) The ATM 2 executes well-known withdrawal processing in response to a withdrawal selection. For example, a screen requesting input of the amount for withdrawal is displayed on the screen 23-1 of the customer operation unit 23, the user inputs an amount, and upon detection of the end of the input process, an amount confirmation screen is displayed on the screen 23-1 of the customer operation unit 23. The control unit 20 detects the pressing of the confirmation key, and displays a screen indicating communication with a computer on the screen 23-1 of the customer operation unit 23.
During this time, the control unit 20 transmits the selected account data and amount for withdrawal to the host computer 5 via the circuit line control unit 26, and obtains a response from the host computer 5. The control unit 20, upon obtaining a response from the host computer 5 permitting withdrawal, issues a receipt from the card unit 24 if an instruction has been given to issue a receipt. The control unit 20 then instructs the cash unit 25 to dispense cash in the amount input. The cash unit 25 dispenses cash (paper currency) in the amount specified, whereupon the control unit 20 displays a paper currency dispensed screen on the screen 23-1 of the customer operation unit 23. The control unit 20, upon detecting removal of the cash, displays a transaction completed screen on the screen 23-1 of the customer operation unit 23. Processing then returns to step S12.
(S20) When a deposit transaction is selected in step S12, the control unit 20 displays a cash (paper currency) insertion screen on the screen 23-1 of the customer operation portion 23. An “Insert bills” guidance message is displayed on this screen. The control unit 20 leaves open the insertion opening of the cash unit 25. When the control unit 20 detects the insertion of paper currency into the insertion opening of the cash unit 25, a screen indicating that paper currency is being counted is displayed on the screen 23-1 of the customer operation unit 23. During this period, the cash unit 25 counts the inserted paper currency.
Upon receiving notification of the completion of counting from the cash unit 25, the control unit 20 displays an amount confirmation screen on the screen 23-1 of the customer operation unit 23. In this screen, the counted amount of money and a confirmation key are displayed. Upon detecting depression of the confirmation key, the control unit 20 displays a screen indicating communication with the computer on the screen 23-1 of the customer operation unit 23. During this time, the control unit 20 transmits the selected account data and the counted amount of money to the host computer 5 via the circuit line control unit 26, and obtains a response from the host computer 5.
If the response from the host computer 5 indicates that a deposit is permitted, when issuing of a receipt has been specified, the control unit 20 issues a receipt through the card unit 24. The control unit 20 then displays a receipt issuing screen on the screen 23-1 of the customer operation unit 23. This screen displays a “Please take your receipt” guidance message. Upon detecting that the receipt has been taken, the control unit 20 displays a transaction completed screen on the screen 23-1 of the customer operation unit 23. Processing then returns to step S12.
(S22) If in step S12 balance inquiry is selected, the control unit 20 displays a screen indicating communication with the computer on the screen 23-1 of the customer operation unit 23. During this time, the control unit 20 transmits the selected account data to the host computer 5 via the circuit line control unit 26, and obtains a response from the host computer 5. Upon receiving a response from the host computer 5, the control unit 20 displays a balance confirmation screen on the screen 23-1 of the customer operation unit 23. In this screen, the “account number”, “account balance”, and a confirmation key are displayed. Upon depression of the confirmation key, if issuing of a receipt has been specified, the control unit 20 causes the card unit 24 to print and issue a receipt. The control unit 20 then displays a receipt issued screen on the screen 23-1 of the customer operation unit 23. Upon detecting removal of the receipt, the control unit 20 displays a transaction completed screen on the screen 23-1 of the customer operation unit 23. Processing then returns to step S12.
In this way, biometrics data is read from the portable telephone 1, biometrics authentication is performed, and account data is used to execute a normal automated transaction. In this case, because the transaction service is requested from a mobile terminal, transaction types are limited to “Withdrawal”, “Deposit”, and “Balance inquiry”. By this means, an excessive number of transaction items are not displayed, for convenience to the user.
As indicated in screen G12 of FIG. 9, the mobile terminal 1 can have data for a plurality of accounts, so that the user need not carry cards for each account. That is, a plurality of cards can be combined, to provide better service to the user.
As a biometrics authentication method suited for use with mobile terminals, in addition to fingerprint authentication, methods of authentication using the blood vessel images of the fingers, blood vessel images of the palms, palm-prints, and similar are appropriate.
Other Embodiments
FIG. 11 is a block diagram of the system of another embodiment of the invention. In FIG. 11, portions similar to those shown in FIG. 1 are assigned the same symbols.
