2. Description of the Related Art
Due to advances in information processing technology in recent years, various illicit transactions using electronic data have become prominent. In particular, as the use of cards together with passwords for individual authentication have become commonplace, the relation between card data and passwords has become widely known, and illicit acquisition of card data and passwords has become prominent, resulting in substantial harm.
Various biometrics technologies utilizing features of the human body have been proposed as methods to resolve problems with such methods using passwords. For example, methods utilizing the fingerprints, retinal images, facial features, blood vessel images (of the palm and fingers), and other features of the body have been proposed. In such biometrics technologies, biometrics data for the individual is registered in advance on an individual card. In order to perform a transaction employing biometrics, a biometrics information reader which acquires biometrics information, provided in the transaction apparatus, is used to acquire biometrics information for the individual. And the acquired biometrics information is compared with registered biometrics data on the individual card; the result of the comparison is used to enable a transaction (see for example Japanese Patent Laid-open No. 2001-067523).
With the spread of portable telephones and other portable terminals in recent years, various individual authentication services based on biometrics which utilize portable terminals have been studied. However, in the technology of the prior art a user must submit an application to have a portable terminal with biometrics functions issued; and various procedures, requiring time, must be performed by the issuer to confirm the identity of the user, register biometrics information for the user, and issue a portable terminal.

The biometrics authentication system in FIG. 1 is an example of a financial system using an ATM (Automated Teller Machine), such as are used by financial institutions.
As shown in FIG. 1, the portable communication terminal 1 is a portable telephone having functions for data reading and writing to and from a contact-free IC card. As explained below using FIG. 2, it is suitable that this portable telephone 1 support the Felica (a registered trademark) standard. For example, the F901i (manufactured by Fujitsu Ltd.) provided by NTT DoCoMo is equipped with a FeliCa-compatible i-application.
A Felica-compatible terminal 6 comprises an automated cash transaction machine, explained in FIG. 3 and FIG. 4. An i-application server 3 communicates with the portable communication terminal 1 over a packet network, and in response to access by the portable communication terminal 1, secures a common area for an i-application in the portable communication terminal 1, and transmits the biometrics application program. A bank host 5 connects to the Felica-compatible terminal 6 and executes transaction processing based on biometrics authentication using the portable communication terminal 1.
The user of the portable communication terminal 1 has an IC card 2 issued by the financial institution. This IC card 2 stores biometrics information (for example, vein data) acquired through image capture by a biometrics image capture device, account information, individual information, and similar.
The automated transaction machine 6 has a biometrics image capture device 10, described below, and a Felica reader/writer 21. This biometrics image capture device 10 acquires vein data (from for example the palm, back of the hand, or fingers) from the body as biometrics information. The Felica reader/writer 21 communicates with a Felica chip in the portable communication terminal 1, and reads and writes data to and from the portable communication terminal 1.
The automated transaction machine 6 reads biometrics information, account information and similar from the IC card 2 of the user, and registers the information in the portable communication terminal 1. This automated transaction machine 6 is connected to the bank host 5, and executes this registration processing.
As indicated in FIG. 2, the above-described portable 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 units.
This portable terminal 1 has browser functions, voice telephony 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. The memory 12 has an i-mode (a registered trademark) application program area 12-1, and a common area 12-2 to store account numbers for which transactions can be performed, 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 application program through a Felica usage request.
As shown in FIG. 3 and FIG. 4, the automated transaction machine 6 has a control unit 60, memory (magnetic disk device) 62, customer operation unit 63, card unit 64, cash unit 65, circuit line control unit 66, and biometrics image capture unit 10 (here, a vein sensor).
The card unit 64 reads the magnetic card/IC card 2 inserted through the card insertion/ejection aperture 6-4 shown in FIG. 3, and returns the card through the aperture. Also, the card unit 64 optically reads (the embossed portion of) a card by optical means. The card unit 64 also uses a printing head to print the transaction result on a receipt form, and the printed receipt is ejected through the card insertion/ejection aperture 6-4.
The UOP unit (customer operation unit) 63 has a display 6-1 with touchscreen (image display portion 63-1 and touchscreen for key input 63-2), a voice guidance unit 63-3, and a customer sensor 63-4.
The cash unit 65 is constructed of a recycling-type paper currency/coin insertion/dispensing device, and has a paper currency/coin counting unit which validates and counts paper currency or coins which have been inserted through the paper currency/coin insertion apertures 6-2, 6-3 in FIG. 3; a paper currency housing portion (stacker) which stacks paper currency/coins; and a unit control portion which performs deposit operations to stack in the stacker counted paper currency and coins, picks up any requested paper currency and coins from the stacker, and dispenses paper currency and coins through the paper currency/coin insertion/dispensing apertures 6-2, 6-3.
The circuit line control unit 66 communicates with the host computer 5 (host of the financial institution) via public circuit lines 4 or similar. The control unit 60 uses programs and data in the memory 62 to control the customer operation unit 63, card unit 64, cash unit 65, and circuit line control unit 66.
Further, the automatic transaction machine 6 has a mobile communication unit 61 which communicates with the portable communication terminal 1. The mobile communication unit 61 comprises a contact-free IC card reader/writer described in FIG. 5, and connected to the control unit 60. The control unit 60 is equipped with software 600 to 670, explained in FIG. 5.
The automated transaction machine 6 of FIG. 3 and FIG. 4 has, on the side of the display with touchscreen 6-1, a vein sensor 10 serving as a biometrics image capture unit. The vein sensor 10 has a sensor unit 48 and, provided in front, a front guide 44 to support the wrist of the user and a flat portion 41.
The front guide 44 has a support portion 44-1 which in turn has a curved portion 44-2 conforming to the shape of the wrist; this support portion 44-1 serves to position the palm of the hand above the sensor unit 48. The sensor unit 48 emits infrared rays which are incident on the palm, and receives the light reflected from the palm, which is converted into electrical signals (image capture data). That is, as is well known, an image of the blood vessels (for example, a vein image) of the user's body is acquired.
Next, the biometrics mechanism installed in the control unit of FIG. 3 and FIG. 4 is explained, referring to FIG. 5. As indicated in FIG. 5, the mobile communication unit 61 comprises an antenna 61A and a RF (Radio Frequency) unit 61B, for use in wireless communication with the Felica chip in the portable communication terminal 1.
Further, the control unit 60 has, as software, a Windows (a registered trademark) or other OS (Operating System) 600, an application program for transaction processing 610, package software 620, and middleware 630.
Moreover, the control unit 60 has a vein authentication driver 670, which drives the biometrics image capture unit 10 (here, a vein sensor); a vein authentication library (program) 660, which performs vein authentication processing; a Felica R/W driver 650, which drives the Felica reader/writer 61; and a Felica library (program) 640, which performs processing of data from the Felica chip 16.
As shown in FIG. 1, in this invention the vein (biometrics) application program is downloaded from the i-application server 3 to the portable communication terminal 1, and an authenticated biometrics information area is created. The user brings the portable communication terminal 1 and IC card 2 to the automated transaction machine 6, causes his own biometrics information to be captured as an image, and upon individual authentication, stores the biometrics data (vein data) and account information in the IC card 2 in the common area 12-2 of the portable communication terminal 1. By this means, the portable communication terminal 1 has the functions of the individual card storing biometrics information, and the process of issuing a card for biometrics ends.
Thereafter, the user causes the automated transaction machine 6 to read the portable communication terminal 1, performs individual authentication based on biometrics, and executes automated transactions for an account. As a result the process of card issuing is simplified. The costs incurred in the issuing process can also be reduced, and biometrics processing can be realized.
Processing To Register Biometrics Functions For A Portable Communication Terminal
FIG. 6 shows the flow of registration processing of a portable communication terminal in an embodiment of the invention, and FIG. 7 explains the operation thereof. As shown in FIG. 6, the i-application server 3 comprises an i-mode server 3A, i-application download server 3B, and Felica-compatible server 3C. First the vein authentication application is registered on the i-application download menu of the i-mode (registered trademark), and the common area 12-2 in the Felica chip 16 is secured.
That is, a user submits an application to a service company which operates a Felica network, and obtains allocation of a specific area in the common area 12-2 and a vein authentication application ID (identifier). The Felica service company stores the allocated ID, area, and registration data necessary for initialization on a Felica-compatible server 3C. In addition, a vein application is registered on an i-application download menu of an i-mode server 3A.
As indicated in FIG. 6, the user accesses an i-mode web page of the i-mode server 3A using an i-mode browser 18 of the portable communication terminal 1. Thereby, the site of the vein authentication application can be selected as an i-application from the portable communication terminal 1.
As shown in FIG. 7, the user operates the portable communication terminal 1 to connect via the mobile communication network 8 to the download site (on the i-application download server) 3B for the vein authentication application, upon which a screen indicating connection with the site is displayed on the display unit 13 of the portable communication terminal 1. The user performs notification authentication using the manufacturing number of the portable communication terminal 1, inputs an authentication number or similar as necessary, and operates the download menu. Thereby, the vein authentication application program is downloaded from the i-application server 3B to the portable communication terminal 1 and is stored in the memory 12. Registration information may be stored on the Felica server 5A in FIG. 8 below, and may be verified at the time of biometrics registration.
Next,the user starts the vein authentication application program downloaded to the portable communication terminal 1, thereby the portable communication terminal 1 connects to the Felica server 3C using an URL (Universal Address Locator) embedded in the vein authentication application program. The Felica server 3C transmits to the portable communication terminal 1 various registration information for the Felica chip 16 (including memory 12), according to the above-described allocated ID from the portable communication terminal 1.
Upon receiving this information, the portable communication terminal 1 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 in FIG. 7 is displayed in the display unit 13 of the portable communication terminal 1, and a vein authentication service area (account area and biometrics information area) is created in the common area 12-2, as shown in FIG. 6.
Here, the palm vein authentication application program performs mutual authentication via the Felica reader/writer 21, thereby area access is limited, and reading/writing of this allocated vein authentication service area is performed according to instructions following above mutual authentication. As described below, biometrics authentication functions are provided by means of which biometrics information (vein data) registered in the biometrics information area of the common area 12-2 may be compared with biometrics information obtained via the Felica reader/writer 21.
In this way, the vein authentication application program is downloaded from a web site to the portable communication terminal 1, and a service area is created in the Felica chip 16. Access to this service area by the vein authentication application program is limited, so that security functions can be imparted, and moreover biometrics media functions can be imparted to the portable communication terminal 1. Hence preparations to issue a card for biometrics can be performed anywhere, and at any time, through user operations.
Processing for Registration and Use of Biometrics Data in a Portable Communication Terminal
Next, FIG. 8 through FIG. 12 are used to explain processing for biometrics data registration and usage by a portable communication terminal. FIG. 8 shows the flow of processing for biometrics data registration and biometrics by a portable communication terminal in an embodiment of the invention; FIG. 9 shows the flow of biometrics data registration processing; and FIG. 10 explains guidance screens for registration processing.
First, biometrics data registration processing is explained. As indicated in FIG. 1, a user carries a portable communication terminal 1 in which is registered the above-described vein application program and an IC card 2, and uses an automated transaction machine 6, shown in FIG. 8 The user inserts the IC card 2 into the automated transaction machine 6. The automated transaction machine 6 provides guidance prompting the user to hold a hand over the biometrics image capture unit 10. The biometrics image capture unit 10 then acquires an image of the veins in the palm of the user's hand. The automated transaction machine 6 verifies the vein data on the IC card 2 against the vein data obtained through image capture to authenticate the individual. This verification processing may be performed within the IC card 2.
Upon authentication of the individual, the user holds his portable telephone (portable communication terminal) 1 with contact-free IC card functions (for example FeliCa functions) over the Felica reader/writer 61 of the automated transaction machine 6. The automated transaction machine 6 and the portable telephone 1 perform mutual authentication by means of the Felica library 640, and when the mutual authentication is satisfactory, the i-application of the portable telephone 1 is started. By this means, the vein authentication application program of the portable telephone 1 is started. A selection menu displaying “Cash card transaction”, “Registered account enquiry”, and “Biometrics registration” is displayed on the display unit of the portable telephone 1.
At this screen, when the user selects “Biometrics registration” or when the “biometrics registration” i-application is started in the automated transaction machine 6, the automated transaction machine 6 writes the vein data, account data and similar on the IC card 2 to the common area 12-2 managed by the vein authentication application program of the portable phone 1 via the Felica library 640, using the Felica reader/writer 21, in response to the selection of biometrics registration.
Through completion of registration, the automated transaction machine 6 notifies the CIF (Customer Information File) 5B in the bank host 5 of the registration of biometrics information, via the bank network 4 as shown in Fig. 8. That is, the account information and registration Information are stored in the CIF 5B.
In this way, biometrics information is registered in the portable telephone 1, so that transactions and similar based on biometrics become possible.
Next, processing to register biometrics data in the portable terminal is explained using FIG. 9, and referring to FIG. 10.
(S10) Selection icons for the normal card transactions of “Deposit”, “Withdrawal”, “Balance inquiry”, and “Update bankbook”, together with “Portable telephone registration”, which registers the portable telephone, are displayed on the customer operation unit 63 of the automated transaction machine 6, as the transaction selection screen G1 (see FIG. 10).
(S12) At the displayed transaction selection screen G1, when the user selects “Portable telephone registration”, the automated transaction machine 6 displays on the customer operation unit 63 a guidance screen G2 prompting for insertion of the IC card 2 into the card insertion aperture 6-4. The user inserts his IC card 2 into the card insertion aperture 6-4 in accordance with this screen G2. The automated transaction machine 6 reads the contents of the IC card 2, and monitors removal of the IC card 2. At this time, the automated transaction machine 6 displays a screen G3 on the customer operation unit 63 indicating that the card is being read.
(S14) The ATM 6 displays a palm vein readout guidance screen G4 on the customer operation unit 63. In response, the user holds the palm of his hand over the vein sensor 10. The vein sensor 10 reads an image of the veins in the palm, and sends the image to the vein authentication library 660 of the ATM 6. The vein authentication library 660 extracts the characteristics of the vein pattern from the vein image, and creates biometrics data (vein data). The vein authentication library 660 of the ATM 6 then verifies the read-out vein data against the vein data registered in the IC card 2, performs confirmation of verification, and displays a screen G5 indicating that authentication is progress on the customer operation unit 63.
(S16) In the event of authentication failure, authentication is retried; if authentication fails even after a prescribed number of retries, an error message is displayed, and processing ends.
(S18) If on the other hand authentication is successful, the ATM 6 displays guidance screens G6 and G7 prompting the user to hold the portable telephone 1 over the Felica sensor 61. The user holds the short-range communication unit 16 of the portable Telephone 1 over the mobile communication unit 61 of the ATM 6, and, through a well-known contact-free IC card read/write sequence, a manufacturing number of other ID is transmitted from the short-range communication unit 16 to the mobile communication 61 of the ATM 6 by contact-free means. Upon receiving this information, the ATM 6 queries the host 5 and judges whether an application for biometrics authentication has been submitted (approved) for the manufacturing number. If there has not been approval for the manufacturing number, the automated transaction machine 6 displays an error message, and processing ends.
(S20) If on the other hand approval has been granted for the manufacturing number of the portable telephone 1, the automated transaction machine 6 uses the Felica reader/writer 21 to write the biometrics data (vein data), account data and similar on the IC card 2 to a common area 12-2 managed by the vein authentication application of the portable telephone 1 via the Felica library 640. Upon completion of this registration, the ATM 6 displays a registration completion screen G8 on the customer operation unit 63, and processing ends.
Upon this registration completion, the automated transaction machine 6 notifies the CIF 5B of the financial institution of the biometrics information registration, as shown in FIG. 8. That is, the CIF 5B stores the account information and registration information. Thus biometrics information is registered in the portable telephone 1, and biometrics-based transactions and similar become possible.
Next, FIG. 11 and FIG. 12 are used to explain biometrics processing.
(S30) As shown in FIG. 11, when the user presses an i-application key on the key input unit 14 of the portable terminal 1, the CPU 11 starts the i-application and displays an i-application standby screen on the display unit 13. The automated transaction machine 6, on the other hand, displays selection icons for the normal card transactions “Deposit”, “Withdrawal”, “Balance inquiry” and “Write bankbook”, as well as the portable telephone transaction “Transaction using portable phone”, on the customer operation unit 63 as the transaction selection screen G10.
(S32) When the user selects “Transaction using portable phone” on the displayed transaction selection screen G10, the automated transaction machine 6 displays a guidance screen G11 on the customer operation portion 63 prompting the user to hold a portable telephone 1 over the Felica sensor 21. The user holds the short-range communication unit 16 of the portable telephone 1 over the mobile communication unit 61 of the ATM 6, whereupon a well-known contact-free IC card read/write sequence is used to transmit, by contact-free means, the above-described account numbers, biometrics information and similar from the short-range communication unit 16 to the mobile communication unit 61 of the ATM 6. The ATM 6, upon receiving this information, displays the account selection screen G12 on the customer operation unit 63. This account selection screen G12 lists the account numbers transmitted from the above-described portable telephone 1. When the user selects the account for the transaction from the customer operation unit 63, a screen G13 for selection of a transaction using a portable telephone is displayed on the customer operation unit 63. This transaction selection screen G13 displays only the above-described transactions which can be performed automatically using the portable telephone 1. Here, only “Withdrawal”, “Deposit”, and “Balance inquiry” can be selected.
(S34) When the user selects a transaction from the customer operation unit 63, the ATM 6 displays a guidance screen G14 for palm vein readout on the customer operation unit 63. In response, the user holds his palm over the vein sensor 10. The vein sensor 10 reads an image of veins in the palm, and transmits the image to the vein authentication library 660 of the ATM 6. The vein authentication library 660 extracts the vein pattern characteristics from the vein image, and creates biometrics data (vein data). The vein authentication library 660 of the ATM 6 then verifies the read-out vein data against the vein data registered in the portable telephone 1, and performs confirmation. In the event of authentication failure (not success), a retry is performed, and if authentication fails even after a prescribed number of retries, the service processing ends, and service processing is obstructed.
(S36) If on the other hand authentication is successful, the ATM 6 judges the type of transaction selected using the portable telephone in step S32.
(S38) In response to selection of withdrawal, the ATM 6 executes well-known withdrawal processing. For example, a monetary amount input screen is displayed on the customer operation unit 63, the user is prompted to input an amount, and when the end of amount input is detected, a monetary amount confirmation screen is displayed on the customer operation unit 63. When the control unit 60 detects the pressing of the confirmation key, a screen indicating communication with a computer is displayed on the customer operation unit 63.
During this interval, the control unit 60 transmits the account data and monetary amount selected to the host computer 5 via the circuit line control unit 66, and obtains a response from the host computer 5. When the response from the host computer 5 permits withdrawal, the control unit 60 causes the card unit 64 to issue a receipt, if the user has requested that a receipt be issued. The control unit 60 then instructs the cash unit 65 to dispense cash in the amount input. The cash unit 65 dispenses cash (paper currency) in this amount, upon which the control unit 60 displays a screen indicating the dispensing of paper currency on the customer operation unit 63. Upon detecting that the cash has been removed, the control unit 60 displays a screen indicating the end of the transaction on the customer operation unit 63. Processing then returns to step S32.
(S40) If in step S32 a deposit transaction has been selected, the control unit 60 displays a cash (paper currency) insertion screen on the customer operation unit 63. At this screen, an “Insert bills” guidance message is displayed. The control unit 60 opens the insertion aperture of the cash unit 65. Upon detecting the insertion of paper currency into the insertion aperture of the cash unit 65, the control unit 60 displays a screen indicating that cash is being counted on the customer operation unit 63. During this interval, the cash unit 65 counts the inserted paper currency.
Upon receiving notification of the end of counting from the cash unit 65, the control unit 60 displays a monetary amount confirmation screen on the customer operation unit 63.
