Description

  The present invention relates to a biometric authentication system that identifies an individual using characteristics of biometric information that is a part of a human body, and in particular, extracts personal characteristic information from information read from a sensor and performs registration and authentication. The present invention relates to a biometric authentication system that outputs a processing result.

  Biological information such as fingerprints, retinas of eyes, blood vessel patterns of finger veins and palm veins is invariant throughout the life, and has individual identification characteristics that the biometric information is different for each individual.

  Therefore, in recent years, attention has been paid to the characteristics of this biometric information, and biometric authentication technology has been developed that extracts biometric information from a part of a human body and identifies an individual from the characteristics.

  For example, biometric authentication systems have come to be used in various scenes for protecting security, such as transaction authentication at financial institutions and door unlocking keys.

  The feature amount extracted from the information of the biological part read from the sensor is the authentication information corresponding to the password in the authentication method before the biometric authentication technology is used, and is the same as or registered with the verification template. It is necessary to stably acquire authentication information that is more than a threshold value in subsequent transactions.

  As a problem when acquiring biological part information used for authentication, it is necessary to read it with a sensor in order to perform authentication processing with a computer, and it is acquired by changes in the surrounding environment such as the light source and humidity and the position of the biological part. There is a possibility that the information that can be made will be different.

  As a method for absorbing such a change, a method of detecting a biological part a plurality of times, extracting a common feature amount from a plurality of times of sensor reading information, and using the common feature amount as information used for actual processing Has been proposed (see Patent Document 1). However, for example, when presenting a finger as a living body part, when the side where the finger's belly should be read by the sensor is registered by presenting the side, the living body part is presented in the correct way for subsequent authentication transactions. Attempting to do so will result in authentication failure.

  As a method for checking that correct authentication information is registered, a method has been proposed that can confirm whether authentication information has been correctly registered by performing an authentication test after registration of the authentication information (Patent Document 2). . However, when an authentication test is performed immediately after registration of authentication information, it is highly likely that the same posture as that at the time of registration is maintained, and thus there is a high possibility that authentication information by the wrong body part presentation method will be registered as it is. .

  That is, there is a limit at present in the mechanical check of whether the correct method of presenting the biological part such as the correct placement position, inclination, and distance from the sensor recommended in the biometric authentication method is correct. Therefore, the most effective method for acquiring correct authentication information is that the user himself / herself understands a correct method for presenting a living body part. However, since it is difficult for a user who has never experienced a biological transaction to show a correct method for presenting a biological part from the beginning, guidance by a third party is important. The most reliable way to give guidance to a user of biometrics is to receive an instruction directly from an instructor who is familiar with biometrics. For example, in banking operations, a counter operator is instructed to allow a user to learn a correct biological transaction method.

JP 2006-6753 A JP-A-1-263775

  For example, even an operator at a bank service window is initially a beginner in biological transactions. Therefore, in order to be able to perform correct business, it is necessary to learn through training the flow of bank business operations and the guidance method including the method of presenting the body part to the user who has visited for biometric transactions. In such a case, the purpose of the biometric transaction itself is not the purpose of the biometric transaction that actually handles the authentication information, but the flow of the biometric transaction by repetitive practice.

  However, the techniques disclosed in Patent Document 1 and Patent Document 2 both perform biometric transactions that handle biometric information when biometric information is acquired. For this reason, in the above-described technology, it is possible to experience and learn the living body part presentation method and the flow of biological transaction operations only through actual biological transactions.

  Therefore, in the above technique, the risk of receiving authentication information acquisition failure or correction of biological body part presentation is imposed on the user in actual transactions. In addition, since the biometric information is information that is invariable throughout the life and can identify an individual, it is necessary to provide sufficient security against unauthorized use such as leakage. For example, it is necessary to prevent trial and error of fraudulent use by malicious others. As such an action, for example, an action such as trying a biometric accuracy using an object that is not a living body such as a mechanical pencil, or attempting an unauthorized authentication by rotating and deforming a biological part to be presented can be considered. Furthermore, in order to prevent forgery, the biometric information should not be easily rewritable.

  In this way, for the purpose of presenting the biometric part and for the purpose of repeatedly practicing the process many times for learning the transaction operation, the method that actually handles biometric authentication information has significant risks and limitations. . For these reasons, biometric authentication information should not be handled in the same way as actual biometrics in order to ensure the strength of security in the practice of biometrics.

  An object of the present invention is to provide a biometric authentication system that can notify a processing result without handling biometric authentication information and without performing verification or registration processing.

  In order to achieve the above object, the present invention provides a biometric authentication system including a biometric authentication device that reads biometric information of a biometric part of a user and a registration terminal that stores setting information related to the operation of the biometric authentication device. The authentication apparatus employs a configuration in which processing is performed according to the setting information and the selected operation mode, and a display unit displays a processing result according to the selected operation mode.

  According to the present invention, it is possible to experience a series of flows of biometric transactions without actually performing transactions dealing with biometric authentication information. Thereby, it is not necessary to deal with an illegal transaction trial by a malicious user and information leakage. Therefore, it is possible to practice a method for presenting a biological part and a biological transaction operation without being restricted by restrictions for ensuring security against fraud such as leakage of biometric authentication information.

  In the practice mode, the system analyzes the biometric information acquisition status from the information read by the sensor in the previous stage of extracting the biometric feature, and presents the user with a correction instruction for the method of presenting the biometric part. You can practice the presentation method by checking repeatedly.

  Hereinafter, embodiments of the present invention will be described in detail.

  As a first embodiment, an example in the case of practicing a biological transaction operation is shown. FIG. 1 is a configuration of a biometric authentication system that performs in-IC card authentication, FIG. 3 is a processing flow of the biometric authentication system in the present embodiment, and FIG. 2 is an example of a screen displayed on the information display device in FIGS. Indicates. This system operates to perform the same process as the actual mode and the actual mode for performing the actual biometric information registration / authentication process, but in practice the two modes are the practice mode in which the biometric information registration / authentication process is not performed. Works with. One is a first mode and the other is a second mode.

  In the present embodiment, in the practice mode, biometric information is read (obtained), the biometric feature amount is not extracted, and a transaction result is set to be successful. Further, in this embodiment, it is assumed that the biometric information readability and the biometric feature amount extraction availability are specified in the setting file 15 in the registration terminal 10.

  The registration terminal 10 in FIG. 1 is a terminal device that includes a CPU 11, a terminal memory 12, and a hard disk 13. Here, the hard disk 13 includes a terminal biometric application 14 and a device setting file 15. The CPU 11 controls the entire registration terminal 10. The terminal biometric application 14 is an application program that performs finger vein authentication processing on the terminal side. The device setting file 15 is a file describing settings regarding whether biometric information acquisition is permitted or not permitted during practice mode operation, and whether biometric feature amounts are permitted to be extracted or not when sensor reading information is acquired. It is.

  An information display device 50, a biometric authentication device 40, and an input device 60 are connected to the registration terminal 10. Here, the information display device 50 is a display or the like that displays information and instructions required by the user. The input device 60 is a touch panel display, a keyboard, or the like that allows a user to input information necessary for a registration transaction or an instruction to the registration terminal 10.

  The biometric authentication device 40 includes a device CPU 41, a device memory 42, a biometric information reading sensor 43, and an IC card reader / writer (hereinafter R / W) 20. The device CPU 41 controls the biometric authentication device 40 as a whole. The biological information reading sensor 43 reads a human biological part represented by fingerprints, voiceprints, facial features, and vein pattern information. An IC card reader / writer (hereinafter referred to as R / W) 20 extracts a feature pattern of biometric information in cooperation with the IC card 30 and writes (registers) or reads biometric information and the like.

  Here, the input device 60, the biometric authentication device 40, and the information display device 50 may be one device, and the biometric authentication device 40, the information display device 50, and the input device 60 are integrated with the registration terminal 10. It may be a configuration. The IC card 30 includes a control unit 31 and a memory 32. The control unit 31 controls communication processing with the IC card R / W 20, authentication information registration processing in the memory, biometric authentication processing, and the like. The memory 32 stores biometric authentication information 34 and a biometric authentication application 33 that controls the biometric authentication information 34. The biometric authentication application 33 may manage information such as account information in addition to the biometric information reading control information.

  FIG. 2 shows an example of a screen displayed by the information display device 50. Screen 201 is a selection that allows the user to select whether to perform biometric transactions (production mode) or to practice biometric transactions and biopart presentation methods without registering biometric authentication information in the IC card (practice mode) The screen is displayed. When the user selects the practice mode on the screen 201, the biometric transaction type of “registration process for registering biometric information” or “authentication process for performing biometric authentication using biometric information” is selected. It is a selection screen that allows the user to select whether to do. The screen 203 is a screen that prompts the user to set a biometric part used for biometric information reading in the biometric authentication device 40 when the user selects the practice mode on the screen 201. Screen 204 is a screen that indicates to the user that biometric information has been registered normally when the user selects practice mode on screen 201 and prompts the user to end the transaction. Although a message indicating that registration is complete is displayed on the screen 204, since it is actually a practice mode, biometric information registration processing is not performed. Further, in this embodiment, the setting is such that success is returned as the processing result, but the display screen when the failure is returned as the processing result is displayed as a screen 205, for example. On the screen 205, a message that is caused by the tilting of the finger that is the biometric part for authentication is written. However, if the cause is other, the content is displayed as a message. Since the screen in the practice mode is for experiencing an actual transaction business, the same screen as that in the case of performing the transaction in the production mode must be displayed. However, in order to explicitly indicate the difference between the actual mode and the practice mode, in this embodiment, the practice mode is displayed at the upper right of the screen in the practice mode.

  Next, the operation of each unit will be described based on the flowchart of FIG. In this embodiment, “practice mode” is selected on the screen 201, and the device setting file 15 includes “a setting for the biometric authentication device 40 to acquire biometric information” and “features of biometric information”. A case will be described in which setting information “setting without extracting amount” is stored.

  When performing the biometric transaction, the CPU 11 of the registration terminal 10 activates the terminal biometric application 14 held in the hard disk 13 and reads the device setting file 15 relating to the application operation into the terminal memory 12 (step 300). Next, the CPU 11 instructs the information display device 50 to display the screen 201, and the information display device 50 displays the screen 201 (step 301). When the CPU 11 acquires the user input (the operation mode selected by the screen 201) in the input device 60 in the terminal memory 12 (step 302), the CPU 11 instructs the information display device 50 to display the screen 202, and the information display device 50 displays the screen 202 (step 303). Next, when the CPU 11 acquires user input (processing menu selected on the screen 202) in the input device 60 in the terminal memory 12 (step 304), the operation mode information held in the terminal memory 12 and whether or not biometric information can be read. The setting information and the setting information indicating whether or not the feature amount can be extracted are transmitted to the biometric authentication device 40 (step 305). Although not shown in the present embodiment, it is assumed that the processing result of the practice mode may be designated at this step. Next, the CPU 11 transmits a process execution instruction such as biometric information registration and biometric authentication (process execution instruction input in step 303) to the biometric authentication apparatus 40 (step 306), and displays the screen 203 on the information display apparatus 50. The information display device 50 displays the screen 203 (step 307). Note that the screen 203 shows a screen example when “Register” is selected on the screen 202.

  The CPU 41 of the biometric authentication device 40 receives the processing execution instruction such as registration and authentication transmitted in step 306, and determines whether the operation mode is the production mode or the practice mode (step 308). As described above, since the practice mode is selected in this embodiment, the practice mode is determined. Next, the CPU 41 determines whether to acquire biometric information or not to acquire biometric information (step 309). As described above, in this embodiment, since the setting is for acquiring biological information (step 309: YES), the biological information reading sensor 43 reads the biological information from the biological part set by the user, and the CPU 41 reads the read biological information. Store in the device memory 42 (step 310). Next, the CPU 41 analyzes the biological information read by the biological information reading sensor 43, and determines whether or not to extract a biological feature amount (step 311). As described above, since the biometric feature amount is not extracted in this embodiment, the CPU 41 transmits the registration / authentication processing result in the practice mode to the registration terminal 10 (step 313). Here, in the practice mode, since the registration / authentication process is not actually performed, a process result based on the actual process cannot be obtained. However, the biometric authentication device 40 does not perform “registration completed” or “authentication successful” in advance. The processing result is stored, and the information is transmitted to the registration terminal 10. Alternatively, a processing result such as “registration failure (and re-registration)” or “authentication failure (and re-authentication)” may be stored together, and this processing result may be transmitted every predetermined number of times.

  Further, the CPU 41 deletes the biometric transaction setting information, the biometric information read by the biometric information reading sensor 43, and the biometric authentication information (in the case of authentication processing) stored in the device memory 42 (step 320). By this processing, the biometric information read in the practice mode can be prevented from remaining in the biometric authentication device 40.

  When receiving the processing result from the biometric authentication device 40, the CPU 11 of the terminal 10 stores the received processing result in the terminal memory 12, and the information display device 50 displays the screen 204 (step 321). When the CPU 11 obtains a transaction end instruction from the user input to the input device 50 (step 322), the information display device 50 displays the operation mode menu selection screen 201 (step 323). In this embodiment, when the processing result is received from the biometric authentication device 40, the screen 204 is displayed in step 321 to end the transaction. However, the registration / authentication processing instruction is transmitted again to the biometric authentication device 40. Then, the biological information reading sensor 43 may perform the biological information reading process again.

  In this embodiment, the case where “practice mode” is selected in step 301 (screen 201) has been described. However, if “production mode” is selected in step 301, the process proceeds from step 308 to step 314. Will migrate. That is, the biometric information reading sensor 43 acquires the biometric information of the biometric part set by the instruction screen displayed in step 307 (step 314), and extracts the biometric feature amount from the acquired biometric information (step 315). .

  Next, in the case of (1) biometric authentication information registration processing (when “registration” is selected in step 303 (screen 202)), the CPU 41 uses the extracted biometric feature amount as the IC card R / W unit 20. Is transmitted to the IC card 30 inserted into the IC card 30 to instruct to register the biometric feature amount (step 316), and the control unit 31 of the IC card 30 uses the received biometric feature amount as biometric authentication information of the IC card 30. 34 (step 317). In the case of (2) authentication processing of biometric authentication information (when “authentication” is selected in step 303 (screen 202)), the extracted biometric feature amount is inserted into the IC card R / W unit 20 by an IC. The card is transmitted to the card 30 and instructed to authenticate the biometric feature (step 316), and the control unit 31 of the IC card 30 registers the received biometric feature in the biometric authentication information 34 of the IC card 30. Compared with the biometric authentication information, biometric authentication is performed (step 317). Then, in both cases (1) and (2), the control unit 31 transmits the processing result to the biometric authentication device 40 (step 318).

  When receiving the processing result from the IC card 30, the biometric authentication device 40 transmits the processing result to the registration terminal 10 as the processing result in the production mode (step 319). Thereafter, the registration terminal 10 performs the processing of steps 321 to 323 described in the practice mode.

  In the production mode, the IC card 30 needs to be inserted into the IC card R / W 20 before the registration / authentication (verification) processing is performed in step 317. For example, the screen 202 (operation menu of step 303) is required. In the selection, after the selection input by the user (step 303), the information display device 50 may display the IC card insertion instruction screen and insert the IC card 30 into the IC card R / W 20. In practice mode, biometric information is not actually registered in the IC card, and biometric authentication (in-card authentication) is not performed with the IC card, so insertion of the IC card is not essential, but practice is performed in the same manner as in the production mode. In the case where it is desired to perform the operation, the IC card may be inserted in the same manner as in the production mode.

  As a second embodiment, an example of practicing a method of setting a biometric part used for biometric authentication in the biometric authentication device 40 will be described. The system configuration (FIG. 1) and display screen example (FIG. 2) are the same as in the first embodiment, and the operation of each part will be described based on the flowchart of FIG.

  In the present embodiment, in the practice mode, the biometric information is acquired and the biometric feature amount is set to be extracted, and unless the biometric information reading sensor 43 fails to acquire the biometric information, the processing result is set to be successful. The case where the transaction is executed is shown. In this embodiment, the biometric transaction operation mode, the biometric information reading enable / disable setting, and the biometric feature extraction enable / disable setting are set in the device setting file 15. Therefore, unlike the first embodiment, the user does not select a mode on the screen 201 (FIG. 2). Of course, the structure which selects an operation mode may be sufficient.

  When performing the biometric transaction, the CPU 11 of the registration terminal 10 activates the terminal biometric application 14 held in the hard disk 13 and reads the device setting file 15 relating to the application operation into the terminal memory 12 (step 400). The CPU 11 transmits the operation mode, biometric information reading availability setting information, and feature amount extraction availability setting information held in the terminal memory 12 to the biometric authentication device 40 (step 401). The CPU 11 instructs the information display device 50 to display the screen 202, and the information display device 50 displays the screen 202 (step 402). When the CPU 11 obtains the selection input by the user input from the input device 60 in the terminal memory 12 according to the screen 202 (step 403), the CPU 11 executes a process execution instruction such as biometric information registration and biometric authentication according to the user selection (in step 303). The input processing execution instruction) is transmitted to the biometric authentication device 40 (step 404), the information display device 50 is instructed to display the screen 203, and the information display device 50 displays the screen 203 (step 405). ). Note that the screen 203 shows a screen example when “Register” is selected on the screen 202.

  The CPU 41 of the biometric authentication device 40 receives the processing execution instruction such as registration and authentication transmitted in step 404, and determines whether the operation mode is the production mode or the practice mode (step 406). In this embodiment, since the practice mode is set, the CPU 41 subsequently determines whether or not to acquire biometric information (step 407). In this embodiment, since it is a setting for acquiring biological information (step 407: YES), the biological information reading sensor 43 reads the biological information from the biological part set by the user and stores the read biological information in the device memory 42. Hold (step 408). Next, the CPU 41 performs biometric reading status analysis on the biometric information read by the biometric information reading sensor 43, and determines whether or not a biometric feature amount can be correctly extracted (step 409). If it is determined that biometric information that can extract biometric features cannot be acquired (step 409: NO), the CPU 41 sets biometric information reading failure as a processing result (step 410). On the other hand, if it is determined that the biometric information that can extract the biometric feature amount has been correctly acquired (step 409: YES), the CPU 41 subsequently analyzes the biometric information to extract the feature amount or extract it. It is determined whether or not to proceed (step 411). In the present embodiment, since it is a setting for extracting the biometric feature amount, the CPU 41 extracts the biometric feature amount from the read biometric information (step 412). Next, the CPU 41 transmits the registration / authentication processing result in the practice mode to the terminal 10 (step 413). As in the first embodiment, this embodiment is also a practice mode, and the registration / authentication process is not actually performed. Therefore, a process result based on the actual process cannot be obtained. ”Or“ successful authentication ”is stored, and the information is transmitted to the registration terminal 10. Alternatively, a processing result such as “registration failure (and re-registration)” or “authentication failure (and re-authentication)” may be stored together and transmitted as a processing result every predetermined number of times.

  The CPU 41 deletes the biometric transaction setting information stored in the device memory 42, the biometric information read by the biometric information reading sensor 43, and the biometric authentication information (in the case of authentication processing) (step 420). By this processing, the biometric information read in the practice mode can be prevented from remaining in the biometric authentication device 40.

  When receiving the processing result from the biometric authentication device 40, the CPU 11 of the terminal 10 stores the received processing result in the terminal memory 12, and if the content is “successful”, the information display device 50 displays the screen 204. If the content is “cause notification due to failure”, the information display device 50 displays the screen 205 (step 421). Next, when the CPU 11 obtains a transaction end instruction from the user input to the input device 50 (step 422), it displays the practice mode menu selection screen 202 (step 423). In this embodiment, the transaction is ended in step 422. However, the registration / authentication processing instruction is issued again to the biometric authentication device 40, and the biometric information reading sensor 43 executes the biometric information reading process again. May be.

  In this embodiment, the case where the “practice mode” is set in the device setting file 15 has been described. However, when the “production mode” is set, the process proceeds from step 406 to step 414. That is, the biometric information reading sensor 43 acquires the biometric information of the biometric part set by the instruction screen displayed in step 405 (step 414), and extracts the biometric feature amount from the acquired biometric information (step 415). .

  Next, in the case of (1) biometric authentication information registration processing (when “registration” is selected in step 402 (screen 202)), the CPU 41 uses the extracted biometric feature amount as the IC card R / W unit 20. Is transmitted to the IC card 30 inserted into the IC card 30 to instruct to register the biometric feature amount (step 316), and the control unit 31 of the IC card 30 uses the received biometric feature amount as biometric authentication information of the IC card 30. 34 (step 417). Further, (2) in the case of authentication processing of biometric authentication information (when “authentication” is selected in step 402 (screen 202)), the extracted biometric feature amount is inserted into the IC card R / W unit 20 by an IC. The card is transmitted to the card 30 and instructed to authenticate the biometric feature amount (step 416), and the control unit 31 of the IC card 30 registers the received biometric feature amount in the biometric authentication information 34 of the IC card 30. Compared with the biometric authentication information, biometric authentication is performed (step 417). Then, in both cases (1) and (2), the control unit 31 transmits the processing result to the biometric authentication device 40 (step 418).

  When receiving the processing result from the IC card 30, the biometric authentication device 40 transmits the processing result to the registration terminal 10 as the processing result in the production mode (step 419). Thereafter, the registration terminal 10 performs the processing of steps 421 to 423 described in the practice mode.
