Description

  The present invention relates to a biometric authentication device.

  IC cards are widely used as personal authentication technology in mobile terminals and credit card payments. Furthermore, biometric authentication using biometric information is spreading for preventing fraud in personal authentication. Biometric authentication includes pupil iris, retina, handwriting, face shape, palm shape, voiceprint, vein, DNA, and the like. This biometric authentication is disclosed in, for example, Patent Document 1 and Patent Document 2.

JP 2005-268951 A JP 2006-227769 A

  Patent Document 1 discloses means for executing a function associated with a fingerprint. Patent Document 2 discloses means for using a plurality of biometric authentication methods depending on the situation.

  In these patent documents, techniques for biometric authentication are also disclosed. However, in biometric authentication, further improvements can be made in terms of improving safety and the like in systems using these. Is preferable.

  For example, Patent Document 1 does not describe a biometric information registration method for associating an operation with an authentication order. In Patent Document 2, an authentication combination is associated with an operation. Is not associated with the action.

  On the other hand, as a biometric authentication method, there is vein authentication in which authentication is performed using an individual vein pattern. Authentication using this vein pattern is being used for authentication in, for example, ATM and entrance / exit management, for example, because it cannot be easily observed from the outside, and there is little psychological resistance.

  However, there is a limit to the biometric information used for authentication, and it can be said that the parts of a living body such as a finger and a palm that can detect and acquire a vein pattern relatively easily are limited at present. Therefore, it is preferable to make some contrivance and technical improvement for further improving the safety of authentication, and this point can be said to be a problem.

  The present invention relates to these problems. In personal authentication, for example, biometric authentication is performed by changing the authentication surface of a finger, and in the process of authentication, smooth authentication and correlation are performed by associating operations with the order of authentication. An object of the present invention is to provide a biometric information registration method, authentication method, and apparatus that enable operation.

  In order to solve the above problems, the outline of typical inventions among the inventions disclosed in the present application will be described as follows.

  As a means to improve safety, etc., it is not limited to the order after biometric authentication such as changing the kind of index finger, middle finger, etc., or before and after the biometric authentication, etc. In addition to the biometric authentication, it is conceivable to perform authentication in combination with other authentication, for example, by inputting a personal identification number.

  Furthermore, based on these, an operation for changing the authentication surface of the finger is performed, and the operation is registered in association with the authentication order of the operation for changing the authentication surface of the finger. It is characterized in that convenience and security are improved by performing biometric authentication once.

  Regarding the disclosure of the invention, other expressions will be described below.

  In a biometric authentication device that authenticates using biometric information, a biometric information reading unit that detects biometric information, a registration data storage unit that registers biometric information detected in association with the order detected by the biometric information reading unit, and A biometric information detected by the biometric information reading unit according to the order and a control unit that performs an authentication process from the biometric information registered in the registered data storage unit are provided.

  Alternatively, in the biometric authentication device, biometric information detected in association with the first order detected by the biometric information reading unit is registered in the registration data storage unit, and detected by the biometric information reading unit The biometric information detected in association with the second order is registered.

  Alternatively, in the biometric authentication device, the biometric information reading unit performs authentication processing from the biometric information detected according to the first order and the biometric information registered in the registration data storage unit, and the biometric information reading unit Authentication processing is performed from the biometric information detected according to the second order and the biometric information registered in the registration data storage unit.

  Typical effects obtained by the present invention disclosed in the above description are as follows.

  By changing the authentication surface of the finger in biometric authentication, the vein pattern to be photographed in two dimensions changes, and the biometric information that can be used can be increased. In addition, by changing the authentication surface of a single finger for multiple authentications, it is possible to perform multiple authentications faster than by changing the authentication method or changing the finger.

  Furthermore, by registering the associating actions in the authentication order, it is possible to register many actions by having the same order of the same biometric information as many times as possible, rather than registering the associating actions in the authentication combination. Confidentiality can be provided by not disclosing the order. With this, it is possible to quickly shift to a target operation after authentication.

  According to the present invention, it is possible to provide a biometric authentication device with improved security and the like than before.

Reference numeral 11 denotes an image reading unit (corresponding to the above-described biometric information reading unit) that can capture a finger vein image by changing the finger authentication surface (finger placement). A control unit 12 includes means such as pattern matching and an input / output interface. Reference numeral 13 denotes an operation screen unit capable of displaying information such as a touch panel display.

  First, an authentication information registration procedure in the present embodiment will be described with reference to the drawings.

  FIG. 1 is a configuration example of a biometric authentication apparatus, FIG. 2 is a registered data storage unit 10, and FIG. 3 is an example of finger placement, which schematically shows finger placement, its vein image, and biometric template. When the finger is placed like the finger placement 200, the image reading unit 11 performs optical correction according to the vertical position, rotational position, angular position, and light amount of the finger, and captures the finger vein image 210. The control unit 12 includes means for controlling input / output of the registration data storage unit 10, the image reading unit 11, and the operation screen unit 13, and includes a signal processing unit 120 and a memory 121. The same unit creates a biological template 102 such as finger vein images 210 to 220 photographed by the image reading unit 11, adds a sequence number 101, and stores it as the biological template information 100.

  Next, when the finger is placed as in the finger placement 201, the image reading unit 11 performs various optical corrections and takes a finger vein image 211. The control unit 12 creates a biological template 102 such as finger vein images 211 to 221 photographed by the image reading unit 11, adds a sequence number 101 different from the above, and stores it as the biological template information 100. An authentication sequence 103 is created using the sequence number 101, a sequence operation 105 corresponding to the authentication sequence 103 is assigned, and stored in the registered data storage unit 10 as sequence information 104.

The image reading unit 11 captures a finger vein image. The control unit 12 collates the biometric template 102 stored in the registered data storage unit 10 with the finger vein image read by the image reading unit 11 and obtains the sequence number 101 of the matched biometric template 102. The control unit 12 determines the authentication sequence 103 from the authentication success sequence number 106 and the sequence number 101 stored in the registered data storage unit 10, and performs a sequence operation 105 corresponding to the authentication sequence 103 when the authentication is completed. With the above configuration, by performing authentication with different finger authentication surfaces multiple times, it is possible to perform authentication multiple times more smoothly than when combined with authentication such as password input or finger change. It is possible to provide a biometric authentication system that is easy to use and has high security. Furthermore, by registering the operations in the order of authentication, it is possible to immediately shift to the target operation, and the convenience can be improved.

  However, this embodiment may be combined with authentication such as input of a PIN number or changing a finger, so that there is no problem even if the security is further improved by doing so. There is no.

FIG. 2 shows the configuration of the registration data storage unit 10.
The registration data storage unit 10 can store at least two or more biometric templates 102 registered by changing the authentication face of the finger together with the sequence number 101 as the biometric template information 100, and stores a sequence operation 105 corresponding to the authentication sequence 103 as the sequence information 104. A memory capable of storing the authentication success sequence number 106 is provided. With the above configuration, the registration data storage unit 10 can store the sequence number 101, the biometric template information 100 including the biometric template 102, the sequence information 104 including the sequence operation 105 associated with the authentication sequence 103, and the authentication success sequence number 106. Therefore, it is possible to assign various operations according to the order of authentication.

The part 11 has a structure that can obtain information necessary for finger vein authentication even when photographing is performed by changing the finger authentication surface. FIG. 5 shows the configuration of the control unit 12.

  In FIG. 5, the control unit 12 is connected to the registration data storage unit 10, the image reading unit 11, and the operation screen unit 13 by a cable or the like, and exchanges data, information, control signals, and control data, and the signal processing unit 120, The memory 121 is configured. The finger vein image 210 obtained from the image reading unit 11 is stored in the memory 121, and the finger vein image 210 is collated with the biological template 102 in the registered data storage unit 10 by the signal processing unit 120. The sequence number 101 of the collated biometric template 102 is stored in the registration data storage unit 10 as the authentication success sequence number 106 and the input from the image reading unit 11 is awaited.

  The finger authentication image 211 obtained from the image reading unit 11 is stored in the memory 121, and the finger vein image 211 is collated with the biological template 102 of the registered data storage unit 10 by the signal processing unit 120.

It may be a thing.

  The finger vein authentication registration procedure of the present embodiment will be described with reference to the flowchart of FIG.

  First, biometric template information registration work will be described. When biometric information registration is started, registration guidance is displayed on the operation screen 33 of the portable terminal 30 as shown in FIG. 13 (S1001), and the user selects biometric information to be registered using the numeric keypad 31 (S1002). When “1” is selected and input, guidance is displayed on the operation screen 33 as shown in FIG. 14 (S1003). As shown in FIG. 3, the user places his / her finger on the image reading unit 32 in a state 200 (S1004), and the image reading unit 32 captures a finger vein image (S1005). The control unit 34 collates the photographed finger vein image 210 with the biometric template 102 stored in the memory 36 (S1006). If they do not match, the biometric template 220 is extracted from the obtained finger vein image 210 (S1007), and an authentication test is started in order to determine whether the image is properly captured (S1008).

  The operation screen 33 displays that the authentication test is started, and when the user places the finger again (S1009), the image reading unit 32 images the finger vein (S1010). The control unit 34 compares the captured finger vein image with the biological template 220 (S1011), and if they match, “1” is assigned to the sequence number 363 (S1012), and biological template information 362 is created (S1013). Registration in the memory 36 (S1014). On the operation screen 33, a registration completion message is displayed as shown in FIG. 15 (S1015). If they do not match, cancel registration.

  Next, the user performs registration by changing the authentication side of the finger. According to the registration guide (S1001), the user selects and inputs “2” (S1002). The operation screen 33 displays that the authentication surface of the finger is changed (S1003). As shown in FIG. 3, the finger is placed in the state 201 where the authentication surface of the finger is changed (S1004), and the image reading unit 32 displays the finger vein image. 211 is photographed (S1005). The control unit 34 compares the photographed finger vein image 211 with the biometric template 102 stored in the memory 36 (S1006). If they do not match, the biometric template 221 is extracted from the obtained finger vein image 211 (S1007), and an authentication test is started to determine whether or not the image is properly captured (S1008).

  The operation screen 33 displays that the authentication test is started, and when the user places the finger again (S1009), the image reading unit 32 images the finger vein (S1010). The control unit 34 compares the photographed finger vein image with the biological template 221 (S1011), and if they match, assigns “2” different from the above to the sequence number 363 (S1012) and creates the biological template information 362. (S1013), registration in the memory 36 (S1014). An image corresponding to the completion of registration and the sequence number 363 is displayed on the operation screen 33 (S1015). If they do not match, cancel registration. The registration procedure is not limited to the above, and the user may appropriately set the sequence number, finger authentication surface, etc., and may automatically detect and register biometric information identification (type, finger authentication surface, etc.). . In the present embodiment, numbers are used for the sequence numbers. However, the present invention is not limited to this, and any character, symbol, or the like can be used.

  Next, the finger vein authentication procedure will be described with reference to the flowchart of FIG.

  Information related to various types of biometric authentication is registered in the memory 36 of the portable terminal 30. It is determined whether the number of authentication failures 370 is within the limit count number (S2001). If the limit count number has been reached, the authentication is stopped, and if not, guidance as shown in FIG. 16 is displayed on the operation screen 33 of the portable terminal 30 to prompt authentication (S2002).

  When the user places a finger on the image reading unit 32 (S2003), the unit 32 performs shooting (S2004). The control unit 34 of the portable terminal 30 collates the finger vein image 210 with the biological template 364 in the memory 36 (S2005). If they match, the value of the sequence number 363 of the collated biometric template 364 is stored in the authentication success sequence number 369 of the memory 36 (S2006), the number of authentication failures 370 is reset (S2007), and the authentication end is completed as shown in FIG. This is displayed and the authentication is terminated (S2008). On the other hand, if they do not match, the authentication failure count 370 is incremented by 1 (S2009), and if the limit count number has not been reached, the process returns to shooting, and if the authentication failure count 370 reaches the limit count number, the authentication is stopped ( S2001).

  Next, the sequence information registration procedure will be described with reference to the flowchart of FIG.

  A registration screen is displayed on the operation screen 33 as shown in FIG. 18 (S3001). In the case of finger vein authentication (sequence number “1”) in the state 200 where the nail is up and finger vein authentication (sequence number “2”) in the state 201 where the finger authentication surface is changed, the sequence is “1”. Since “2”, the user selects and inputs “12” in the authentication sequence registration field to be registered (S3002).

  An authentication test is performed according to the selected authentication sequence. The user performs authentication in the order of finger vein authentication in the state 200 where the nail is on (S3003) and finger vein authentication in the state 201 where the finger authentication surface is changed (S3004). The determined authentication sequence is compared with the authentication sequence obtained by the authentication (S3005), and if they match, the authentication sequence 366 is assigned to the sequence operation 367 “application activation” (S3006), and “login information” is added as additional information 368. "Is added (S3007), sequence information 365 is created (S3008) and registered (S3009). As shown in FIG. 19, the completion of registration is displayed on the operation screen 33 (S3010), and the registration is terminated. If they do not match, registration is canceled.

  Contrary to the above, when the finger vein authentication is performed in the state 201 in which the authentication order of the finger is changed and the finger vein authentication is performed in the state 200 where the nail is on the upper side, the sequence is “2” → “1”. Therefore, the user selects and inputs “21” in the authentication sequence registration field to be registered (S3002). An authentication test is performed according to the selected authentication sequence.

  The user performs authentication in the order of finger vein authentication (S3003) in the state 201 with the finger authentication surface changed, and finger vein authentication in the state 200 where the nail is on the top (S3004). The determined authentication sequence is compared with the authentication sequence obtained by the authentication (S3005), and if they match, the sequence operation 367 “mode change” is assigned in association with the authentication sequence 366 (S3006), and “setting information” is added as additional information 368. "Is added (S3007), sequence information 365 is created (S3008) and registered (S3009). A confirmation screen is displayed on the operation screen 33 as shown in FIG. 19 (S3010), and the registration is completed. If they do not match, registration is canceled. In addition, after selecting an operation, the user may perform authentication in an arbitrary order, and the authentication sequence may be determined based on the authentication order.

  Next, the sequence operation authentication procedure will be described with reference to the flowchart of FIG.

  A guidance as shown in FIG. 20 is displayed on the operation screen 33 of the portable terminal 30 to prompt authentication (S4001). When the user activates the application, first, finger vein authentication is performed in a state 200 where the nail is on the top (S4002). At this time, “1” of the sequence number 363 is stored in the authentication success sequence number 369. Next, the operation screen 33 of the portable terminal 30 displays that the verification is successful and the finger authentication surface is changed as shown in FIG. 21 (S4003), and the user performs finger vein authentication in a state 201 in which the finger authentication surface is changed. Is performed (S4004). From the authentication success sequence number 369 and the value “2” of the sequence number 363 succeeded in the second authentication, the control unit 34 changes the sequence from “1” to “2” and the authentication sequence becomes “12” (S4005).

  The control unit 34 determines whether the obtained authentication sequence is registered in the sequence information 365 of the memory 36 (S4006). When the authentication sequence obtained above is not registered, the operation screen 33 displays that the authentication sequence is not registered, and the authentication is stopped. If registered, the sequence information 365 is acquired (S4007), the control unit 34 shifts to “application activation” which is a sequence operation 367 corresponding to the authentication sequence 366, and the operation screen unit 33 shifts the operation. 22 is displayed (S4008), and the operation is shifted upon completion of authentication.

  On the other hand, when the user changes the mode, first, finger vein authentication is performed in a state 201 in which the finger authentication surface is changed (S4002). At this time, “2” of the sequence number 363 is stored in the authentication success sequence number 369. Next, the operation screen 33 of the portable terminal 30 displays that the collation is successful and the finger authentication surface is changed (S4003), and the user performs finger vein authentication in a state 200 where the nail is placed (S4004).

  From the authentication success sequence number 369 and the value “1” of the sequence number 363 succeeded in the second authentication, the control unit 34 changes the sequence from “2” to “1” and the authentication sequence becomes “21” (S4005). The control unit 34 determines whether the obtained authentication sequence is registered in the sequence information 365 of the memory 36 (S4006).

  When the authentication sequence obtained above is not registered, the operation screen 33 displays that the authentication sequence is not registered, and the authentication is stopped. If registered, the sequence information 365 is acquired (S4007), the control unit 34 shifts to “mode change” that is the sequence operation 367 corresponding to the authentication sequence 366, and the operation screen unit 33 displays that the operation shifts. (S4008), the operation is shifted upon completion of authentication. With the above configuration, separate authentication can be performed multiple times with one finger, and security can be improved compared to a single-side authentication by performing authentication on the authentication surface of different fingers. Moreover, since operations can be registered according to the order of authentication, input operations and the like can be omitted, and convenience is improved.

  In this embodiment, an authentication embodiment using finger vein information will be described. However, the biometric information may be information other than finger vein information, for example, a fingerprint, and the finger vein information may be a part other than a finger, such as a palm. There is no particular limitation on the vein information obtained from the living body. For example, if vein information of the whole body can be acquired by improving the device or the like, the acquired vein information may be used.

  Note that the operation was canceled when an unauthorized process such as an authentication failure was performed during registration, authentication test, or authentication. However, the present invention is not limited to this. You may move to.

  The biometric template information is not limited to the biometric information, and optical correction information of the image reading unit may be registered together with the biometric information. Depending on the authentication order, authentication of finger orientation, type, etc. may be performed. When the method is expected, the optical system may be corrected in advance from the correction information of the registered optical system to improve accuracy and speed.

  In this embodiment, authentication is urged by an image, but this may be text information, voice information, or the like, or a combination of them, and at the time of authentication, the authentication order and operation are not displayed to provide confidentiality and security. May increase. In the first embodiment, the sequence operation is determined based on the authentication order. However, a plurality of biometric authentication devices may be used to perform a plurality of biometric authentications, and the operation may be associated with the authentication order.

  The biometric authentication device of the first embodiment performs a series of operations, finger vein registration, sequence operation registration, finger vein authentication, and sequence operation authentication in one device. By sharing the role of the device and authentication work such as ATM, unauthorized rewriting becomes difficult, and biometric authentication with higher security becomes possible. A modification of the first embodiment will be described by taking a financial transaction as an example.

  23 shows the IC card 14, FIG. 24 shows the registration device 16, and FIG. 25 shows the ATM 17. First, the registration procedure will be described. The IC card 14 shown in FIG. 23 includes a memory capable of storing a personal identification number 140, an account number 141, biometric template information 142, sequence information 145, an authentication success sequence number 150, and an authentication failure count 151.

  At least two pieces of biometric template information 142 including the biometric template 144 to which the sequence number 143 is assigned in the IC card 14 are stored. The authentication sequence 146, the sequence operation 147 corresponding to the authentication sequence 146, and the importance of each operation The sequence information 145 including the minimum number of authentication times 148 determined by the above and additional information 149 is stored.

  For example, when assigning a sequence to “withdrawal”, the minimum number of authentications to be performed is 3 times or more from the minimum number of authentications 148, and “balance inquiry” is the minimum number of authentications to be performed from the minimum number of authentications 148 to 1 or more. It is possible to set a minimum authentication count 148 according to the degree. At the time of registration work, first, the IC card 14 is inserted into the card insertion slot 160 of the registration device 16. The control unit 163 performs an initial operation with the IC card 14, and the display screen 161 displays the screen as shown in FIG. The user selects the sequence operation 147 to be registered. If “withdrawal” is selected, the minimum authentication count 148 of “withdrawal” is “3”, and the user inputs an authentication sequence of three or more digits so that authentication is performed three times or more.

  The registration device 16 determines the number of authentications based on the number of digits in the input authentication sequence. If the number of authentications is less than the minimum number of authentications 148, the registration device 16 displays that fact on the operation screen 161 and stops registration. When the authentication number of the input authentication sequence is the minimum authentication number 148 or more, the user places a finger on the screen reading unit 162 according to the authentication sequence, and an authentication test is performed. If the authentication test is successful, the user inputs additional information 149, and the control unit 163 assigns an authentication sequence to the sequence operation and creates and registers sequence information 145. Confirmation is displayed on the display screen 161 as shown in FIG.

  FIG. 28 is a display example and flowchart regarding the sequence operation authentication procedure.

  The user inserts the IC card 14 into the card insertion slot 170 of the ATM 17. The control unit 171 performs an initial operation with the IC card 14. The ATM 17 operation screen 172 displays a prompt for authentication as shown in FIG. 29, the user places his finger on the finger vein sensor 173, and the control unit 171 performs the first authentication (S5001). When the finger arrangement 401 is verified, the authentication success sequence number 150 is “1”, and the control unit 171 determines that the authentication sequence is “withdraw” or “deposit” in the sequence operation 147 starting from “1”. If the authentication success sequence number 150 and the authentication sequence 146 do not match, the process proceeds to the next step (S5002).

  A display for prompting the next authentication is displayed on the operation screen 172 of the ATM 17 as shown in FIG. 30. Next, when the finger arrangement 402 is verified, the authentication success sequence number 150 becomes “12”, and the corresponding sequence operation is the authentication. If it is determined that the sequence 146 is “withdrawal” starting from “12” and the authentication success sequence number 150 does not match the authentication sequence, the process proceeds to the next step (S5003). When the operation screen 172 is displayed as shown in FIG. 31 and the finger placement 401 is further verified, the authentication success sequence number is “121”, and “withdraw” is a sequence operation 147 corresponding to the matching authentication sequence 146. Is displayed as shown in FIG. 32, and the process proceeds to operation (S5004).

  On the other hand, when the finger placement 402 is verified in the first authentication, the authentication success sequence number 150 is “2”, and the corresponding sequence operation 147 is “balance inquiry” in which the authentication sequence 146 matches “2”, or Judged as “deposit” starting from “2”. In the above case, the screen is displayed as shown in FIG. 33. When the user wants to perform “Balance inquiry”, the user selects it on the operation screen 172. The control unit shifts to “balance inquiry” when selected, and performs authentication processing when a finger is placed.

  If the user does not select but sets a time limit and the finger is not placed within the time limit, the authentication operation may be terminated and the process may proceed to “Balance inquiry”. Also good. As the number of authentications increases, the number of operations that can be registered increases. Furthermore, for example, convenience can be emphasized by changing the accuracy of verification to be lower than the number of authentications.

  In the description of the above embodiment, a finger has been described as an example, but the present invention is not limited to the finger.

  Therefore, of course, the present invention may be applied as long as it is biological information that can be acquired by a detector, a detection device, and a detection method.

  For example, the above-mentioned biological information includes iris, retina, handwriting, face shape, palm shape, voice print, vein, DNA, etc. of the pupil, and the present invention is implemented in association with the biological information acquisition operation regarding the living body including these. It may be what you do. For example, the related operation from the authentication of the handwriting by the writing order, the related operation from the authentication of the voiceprint by the utterance order, and the like. Of course, a combination of a plurality of these pieces of biological information may be used.
