[0003] [Patent Document 1] JP 2003-034235 A [Patent Document 2] Special Publication No. 2017-537416 Summary of the Invention [Problem to be solved by the invention]

[0004] A fingerprint sensor used in a fingerprint authentication device performs a fingerprint detection process to detect a fingerprint when a finger is placed in contact with a fingerprint reading portion. There are various types of mechanisms for such fingerprint detection processes, such as a capacitance type and a field strength type, but there is a risk of radio wave noise being generated from the fingerprint sensor when the fingerprint detection process is performed. When a fingerprint authentication device is installed in a vehicle, if a user inadvertently touches the fingerprint sensor, the fingerprint detection process will be performed even if it is not necessary, and the radio wave noise may cause noise in the radio audio, degrading the sound quality, and reducing comfort inside the vehicle.

[0005] The present invention has been made in consideration of the above-mentioned problems, and aims to provide an authentication device, etc. that reduces the risk of affecting comfort inside the vehicle when the fingerprint sensor is inadvertently touched. [Means for solving the problem]

[0006] In order to solve the above problem, one aspect of the present invention is an authentication device mounted on a vehicle, the authentication device comprising: an acquisition unit that acquires biometric information of a user; an authentication unit that performs authentication processing based on the biometric information acquired by the acquisition unit; and a control unit that controls the authentication unit not to perform the authentication processing when the vehicle is not stopped. Effect of the Invention

[0007] The present invention can provide an authentication device that reduces the risk of affecting the comfort inside the vehicle when the fingerprint sensor is inadvertently touched. [Brief description of the drawings]

[0009] (Embodiment) In a fingerprint authentication device and system according to an embodiment of the present invention, under circumstances where it is assumed that a fingerprint detection process for fingerprint authentication will not be required, the fingerprint sensor suppresses the fingerprint detection process. As a result, even if a user inadvertently touches the fingerprint reading portion of the fingerprint sensor, the fingerprint sensor does not execute the fingerprint detection process, so that radio noise is not generated, and it is possible to suppress the risk of a decrease in comfort inside the vehicle, such as a decrease in the sound quality of the radio. Hereinafter, the present embodiment will be described in detail with reference to the drawings.

[0010] <Configuration> Fig. 1 shows a functional block diagram of a fingerprint authentication device 1 according to this embodiment. The fingerprint authentication device 1 is mounted on a vehicle, and includes a fingerprint sensor 11, a fingerprint authentication unit 12, and a control unit 14. In the example shown in Fig. 1, the fingerprint sensor 11 is formed integrally with a push start switch 13, and constitutes a sensor unit 10 together with the fingerprint authentication unit 12. Moreover, the control unit 14 constitutes a matching unit 20, which will be described later, as an example.

[0011] When a finger is placed in contact with a fingerprint reading portion, the fingerprint sensor 11 performs a fingerprint detection process in which the embossed pattern of the finger is captured and detected as a fingerprint. The specific method of the fingerprint detection process is not limited. The fingerprint authentication unit 12 performs a fingerprint authentication process for the user based on the fingerprint detected by the fingerprint detection process of the fingerprint sensor 11. The fingerprint authentication method by the fingerprint authentication unit 12 is not limited, but for example, one or more fingerprints are registered in advance in association with an identifier, the detected fingerprint is compared with the registered fingerprint, the degree of match is calculated by a predetermined method, and if the degree of match is equal to or greater than a predetermined level, the fingerprint authentication is successful. The sensor unit 10 notifies the comparison unit 20 of the fingerprint authentication result.

[0012] The push start switch 13 is a switch that detects that it is pressed and switches its internal state between on and off. The fingerprint reading portion of the fingerprint sensor 11 is provided on the surface of the push start switch 13. That is, for example, when the push start switch 13 is pressed by a finger, the fingerprint sensor 11 can execute a fingerprint detection process.

[0013] The collation unit 20 controls the authentication process using wireless communication with a portable device 40 such as a smart key and the fingerprint authentication process by the sensor unit 10. These authentication processes can collate the acquired user information with information of a user who has the legitimate authority to operate the vehicle and is registered in advance. The collation unit 20 determines whether the user can operate the vehicle and the operation of the vehicle according to the collation result. If necessary for such processing, the collation unit 20 can communicate with one or more other in-vehicle devices 30 to appropriately acquire various vehicle states and notify the processing results. In addition, such processing may be entirely performed by the control unit 14, or the collation unit 20 may include another control unit (not shown) different from the control unit 14, and the control unit 14 may perform part of the processing including the control of the sensor unit 10, and the other control unit may perform the remaining processing such as communication with the portable device 40 and other in-vehicle devices 30.

[0014] <Processing> In this embodiment, the fingerprint authentication is typically performed to determine whether or not to permit a transition to an ignition-on (ready-on) state. The fingerprint authentication is also performed when another in-vehicle device such as a navigation device requests authentication of the user.

[0015] Therefore, in this embodiment, the control unit 14 of the matching unit 20 controls the fingerprint sensor 11 based on the vehicle state acquired by the matching unit 20, and when there is a high possibility that fingerprint authentication will be requested, the fingerprint detection process is permitted, and when fingerprint authentication is not requested, the fingerprint detection process is not permitted. In the fingerprint detection process permitted state, the fingerprint sensor 11 executes the above-mentioned fingerprint detection process when a finger touches the fingerprint reading portion. In the fingerprint detection process not permitted state, the fingerprint sensor 11 does not execute the above-mentioned fingerprint detection process even if a finger touches the fingerprint reading portion. There is no limitation on how to realize the fingerprint detection process not permitted state, but it is sufficient to suppress the execution of the fingerprint detection process of the fingerprint sensor 11 that generates radio wave noise in the sensor unit 10, for example, by restricting the power supply to the fingerprint sensor 11. Note that the operation of the parts other than the fingerprint sensor 11, such as the fingerprint authentication unit 12, may not be particularly restricted even when the fingerprint detection process is not permitted.

[0016] 2 shows a state transition diagram of the fingerprint sensor 11. In the initial state, the fingerprint sensor 11 is in a fingerprint detection processing disallowed state. In the fingerprint detection processing disallowed state, if a predetermined permission condition is met, the state transitions to a fingerprint detection processing permitted state. In addition, in the fingerprint detection processing permitted state, if a predetermined non-permission condition is met, the state transitions to a fingerprint detection processing non-permission state.

[0017] An example of the permission conditions and non-permission conditions will be described below.

[0018] First, the permission condition is a condition that represents the state of the vehicle in which it is assumed that the fingerprint detection process is required for fingerprint authentication. In the present embodiment, the permission condition is as follows, for example. That is, the permission condition is that the following (1) is satisfied, and at least one of (2) to (7) is satisfied. (1) The vehicle speed is below a predetermined value (e.g., below 5 km / h). (2) The brakes are applied. (3) The driver's door changed from a closed to an open position. (4) The driver's door changed from an open to a closed position. (5) The push start switch changed from off to on. (6) A fingerprint authentication request was received from another in-vehicle device. (7) The vehicle's power has changed from a state other than off to the off state.

[0019] In this embodiment, fingerprint authentication is typically performed to determine whether or not to permit a transition to an ignition-on (ready-on) state while the vehicle is stopped. Also, performing fingerprint authentication while the vehicle is moving is suppressed to improve safety. Therefore, if the permission condition is that the vehicle is stopped, the fingerprint detection process by the fingerprint sensor 11 can be suppressed. In reality, the permission condition may be that the vehicle speed is less than a very small predetermined value, such as 5 km / h, taking into account the error in the detection speed of the vehicle, as in (1) above. Furthermore, if the permission condition is limited according to the contents of (2) to (7), the permission condition can be limited to a case where it can be assumed with a higher degree of certainty that the fingerprint detection process will be requested, and the fingerprint detection process by the fingerprint sensor 11 can be suppressed more suitably.

[0020] In this embodiment, in order to transition to the ignition on (ready on) state, for example, the parking brake is operated, the shift position is in park, and the brake pedal is depressed in a specific vehicle state, the push start switch 13 is pressed to turn on, and fingerprint authentication must be successful. Therefore, the permission condition can be limited by, for example, the brake being in operation as in (2) above, in addition to the situation where the above (1) is satisfied.

[0021] Alternatively, if a user gets into the driver's seat or if the user who sits in the driver's seat is changed, there is a high possibility that the state will transition to the ignition on (ready on) state. Therefore, the permission condition can be limited to a situation where the above-mentioned (1) is satisfied, and further, as in the above-mentioned (3) or (4), there is a high possibility that the user gets into the driver's seat or the user who sits in the driver's seat is changed.

[0022] Alternatively, the permission condition can be limited by the fact that the above-mentioned (1) is satisfied and further, as mentioned above in (5), the user actually presses the push start switch 13 to transition to the ignition on (ready on) state, etc., causing the push start switch 13 to change from the off state to the on state.

[0023] Alternatively, it is assumed that the user receives billing services by communicating with a server outside the vehicle via another in-vehicle device 30 such as a navigation device while the vehicle is stopped. It is conceivable that the fingerprint authentication device 1 is used for user authentication required for such services. Therefore, the permission condition can be limited by the fact that the above-mentioned (1) is satisfied, and further by the fact that a fingerprint authentication request has been received from another in-vehicle device 30 as in the above-mentioned (6).

[0024] Alternatively, the user may, for example, press the push start switch 13 to transition from a state other than the power off (ignition on (ready on) or ACC on) to the off state, and then press the push start switch 13 again to transition to the ignition on (ready on) state. Therefore, the permission condition can be limited under the circumstances where the above (1) is satisfied, and further by the fact that the vehicle power has changed from a state other than the off state to the off state, as in the above (7).

[0025] When it is expected that fingerprint detection processing will be required for fingerprint authentication due to the permission conditions as described above, the fingerprint sensor 11 is set to a fingerprint detection processing permission state, and fingerprint authentication is enabled by the fingerprint authentication device 1. Note that the permission conditions are not limited to those described above, and may be set appropriately according to the situation in which fingerprint authentication is required based on the vehicle operation specifications, etc. For example, the contents of the above (1) to (7) may be changed or deleted as appropriate, or other contents may be added.

[0026] Next, the disallowance condition is a condition that represents a vehicle state in which it is assumed that fingerprint detection processing for fingerprint authentication is not required. In the present embodiment, the disallowance condition is as follows, for example. That is, the disallowance condition is that at least one of the following (8) to (10) is satisfied. (8) The vehicle speed is above a predetermined value (e.g., 5 km / h or more). (9) The vehicle power supply is on (ACC on), the fingerprint authentication process by the fingerprint authentication unit 12 is successful, and the fingerprint sensor 11 is a genuine product. (10) The vehicle power supply is on (ACC on), and the fingerprint authentication unit 12 has successfully performed a predetermined substitution process for the fingerprint authentication process.

[0027] In this embodiment, as described above, fingerprint authentication is typically performed while the vehicle is stopped to determine whether or not to permit the vehicle to transition to an ignition-on (ready-on) state. In addition, fingerprint authentication is suppressed while the vehicle is running to improve safety. Therefore, when the vehicle is running and satisfies the above-mentioned (8), it can be assumed that fingerprint detection processing is unnecessary.

[0028] In this embodiment, the operation specification is assumed such that, in a specific vehicle state, the push start switch 13 is pressed to turn it on, thereby turning the vehicle into the ACC on state, and if fingerprint authentication is successful, the vehicle transitions to the ignition on (ready on) state via the ACC on state. Regardless of whether the above-mentioned (8) is successful or not, if (9) is satisfied, the vehicle is already in a state where it is about to transition to the ignition on (ready on) state, and in this state, further fingerprint detection processing is not required, and therefore the fingerprint detection processing by the fingerprint sensor 11 is suppressed. Note that whether the fingerprint sensor 11 is genuine or not can be determined, for example, by the collation unit 20 authenticating the fingerprint sensor 11 by performing a specific communication with the fingerprint sensor 11 through the collation unit 20.

[0029] In this embodiment, the operation specification is assumed that, in a predetermined vehicle state, the push start switch 13 is pressed to turn it on, thereby turning the vehicle into the ACC on state, and if authentication by communication using a transponder built into the portable device 40 or the like instead of fingerprint authentication is successful, the vehicle transitions to the ignition on (ready on) state via the ACC on state. Regardless of whether the above (8) and (9) are successful, if (10) is satisfied, the vehicle is already about to transition to the ignition on (ready on) state, and further fingerprint detection processing is not required under this condition, so the fingerprint detection processing by the fingerprint sensor 11 is suppressed. Note that the processing that can be substituted for fingerprint authentication is not limited to authentication by communication using a transponder. It is sufficient to set the disallowance condition according to the alternative processing provided by the vehicle.

[0030] When it is expected that fingerprint detection processing for fingerprint authentication will not be required due to the above-mentioned disallowance conditions, the fingerprint sensor 11 is set to a fingerprint detection processing disallowance state, and fingerprint authentication is not performed by the fingerprint authentication device 1. Note that the disallowance conditions are not limited to those described above, and may be set appropriately according to a situation in which fingerprint authentication is not required based on the vehicle operation specifications, etc. For example, the contents of the above (8) to (10) may be changed or deleted as appropriate, or other contents may be added.

[0031] <Processing example> 3 is a diagram showing an example of a processing sequence of the collation unit 20 and the sensor unit 10. An example of the processing will be described with reference to FIG.

[0032] 3, the sequence of steps S101 to S111 is executed from when the user gets into the vehicle until the vehicle is driven. When step S101 starts, the vehicle is stopped and the fingerprint sensor 11 is in a fingerprint detection process disallowed state.

[0033] (Step S101): A user opens the driver's door, gets into the driver's seat, and depresses the brake pedal. The collation unit 20 acquires the open / closed state of the vehicle door from the other in-vehicle device 30, and detects that the driver's door of the vehicle has changed from a closed state to an open state, or from an open state to a closed state. The collation unit 20 also acquires the operation state of the brake pedal from the other in-vehicle device 30, and detects that the brake pedal is depressed and the brake is operating. Furthermore, the collation unit 20 acquires the speed of the vehicle from the other in-vehicle device 30, and detects that the vehicle is stopped. As a result, the above-mentioned contents of (1), (2) and [(3) or (4)] constituting the permission condition are established. Note that, before the execution of this step, when a user carrying the portable device 40 approaches the vehicle and operates the door handle, the collation unit 20 may authenticate the portable device 40 by wireless communication outside the vehicle, and permit the opening and closing of the door based on the successful authentication.

[0034] (Step S102): In step S101, since the permission conditions are met, the matching unit 20 notifies the sensor unit 10 that the fingerprint sensor 11 is in a fingerprint detection processing permission state. The sensor unit 10 receives the notification and puts the fingerprint sensor 11 in a state in which the fingerprint detection processing is executed when a finger comes into contact with the fingerprint sensor 11.

[0035] (Step S103): The matching unit 20 authenticates the portable device 40 brought into the vehicle by the user through wireless communication within the vehicle. If the authentication is successful, the matching unit 20 identifies the user who possesses the portable device 40 as a user who was previously associated and registered with the authenticated portable device 40. The matching unit 20 stores the association between the user and the fingerprint identifier registered in the sensor unit 10, and notifies the sensor unit 10 of the identifier corresponding to the fingerprint of the identified user.

[0036] (Step S104): The collation unit 20 communicates with the sensor unit 10 to authenticate the fingerprint sensor 11, and if the authentication is successful, it is confirmed that the fingerprint sensor 11 is a genuine product and not a counterfeit product that has been replaced.

[0037] (Step S105): When the user touches the fingerprint reading portion of the fingerprint sensor 11 of the push start switch 13, the sensor unit 10 detects this.

[0038] (Step S106): When the user continues to press the push start switch 13 and the push start switch 13 changes from the OFF state to the ON state, the sensor unit 10 notifies the collation unit 20 of this.

[0039] (Step S107): The collation unit 20 determines that the vehicle state is to be power-on (ACC on) and also appropriately notifies other in-vehicle devices 30 as necessary to actually achieve this state.

[0040] (Step S108): When the user continues to touch the fingerprint reading portion of the fingerprint sensor 11 with the push start switch 13, the fingerprint sensor 11 captures the fingerprint and performs fingerprint detection processing.

[0041] (Step S109): If the degree of match between the fingerprint detected in step S108 and the fingerprint stored in advance that corresponds to the identifier notified in step S103 is at least to a predetermined level, the fingerprint authentication unit 12 determines that the user authentication has been successful and notifies the comparison unit 20 of the result.

[0042] (Step S110): As a result of steps S104, S107, and S109, the above content of (9) is established, and therefore the disallowance condition is established. Therefore, the matching unit 20 notifies the sensor unit 10 that the fingerprint sensor 11 is in a fingerprint detection processing disallowance state. The sensor unit 10 receives the notification and sets the fingerprint sensor 11 to a state in which the fingerprint detection processing is not performed even if a finger touches it.

[0043] (Step S111): The collation unit 20 confirms that all conditions for setting the vehicle state to the ignition on (ready on) state are met, and decides to set the vehicle state to the ignition on (ready on) state. As described above, the conditions for setting the vehicle state to the ignition on (ready on) state are, for example, that the parking brake is operated, the shift position is in park, the brake pedal is depressed, the push start switch 13 is pressed to set the switch to the on state, and fingerprint authentication is successful. The collation unit 20 also appropriately notifies other in-vehicle devices 30 of the necessary information to actually set the vehicle state. This puts the vehicle in a state in which it can be driven.

[0044] With the above processing, even if a user inadvertently touches the fingerprint reading portion of the fingerprint sensor 11 provided on the push start switch 13 while the vehicle is running, the fingerprint sensor 11 does not execute the fingerprint detection process, so that no radio noise is generated and the risk of a decrease in comfort inside the vehicle, such as a decrease in the sound quality of the radio, is reduced.

[0045] 3, the sequence of steps S201 to S205 is executed from when the vehicle is running until the vehicle is stopped and the power is turned off. When step S201 starts, the vehicle is running and the fingerprint sensor 11 is in a fingerprint detection process disallowed state.

[0046] (Step S201): The user depresses the brake pedal to stop the vehicle. The collation unit 20 acquires the vehicle speed and detects that the vehicle is stopped.

[0047] (Step S202): When the user touches the push start switch 13, the sensor unit 10 detects this.

[0048] (Step S203): When the user continues to press the push start switch 13 and the push start switch 13 changes from the on state to the off state, the sensor unit 10 notifies this to the matching unit 20. Note that the fingerprint sensor 11 is in a fingerprint detection processing disabled state, so the fingerprint detection processing is not performed.

[0049] (Step S204): The collation unit 20 determines to put the vehicle into a power-off state, and also appropriately notifies other in-vehicle devices 30 of the necessary information to actually put the vehicle into this state.

[0050] (Step S205): In step S201, it is detected that the above-mentioned content of (1) constituting the permission condition is satisfied, and in step S204, it is detected that the above-mentioned content of (7) constituting the permission condition is satisfied. Since the permission condition is satisfied, the collation unit 20 notifies the sensor unit 10 that the fingerprint sensor 11 is in a fingerprint detection processing permission state. The sensor unit 10 receives the notification and sets the fingerprint sensor 11 to a state in which the fingerprint detection process is executed when a finger touches it. After this step is executed, the vehicle is in the same state as after the above-mentioned step S102 is executed, and the sequence for transitioning to the ignition on (ready on) state again can be executed.

[0051] At any timing in the above sequence, if it can be estimated based on the reception state of radio waves from the portable device 40 that the user carrying the portable device 40 has got off the vehicle or has moved a predetermined distance or more away from the vehicle, the fingerprint sensor 11 may be set to a fingerprint detection processing disallowed state regardless of whether the above-mentioned permission conditions and disallowance conditions are met. Also, if various authentications fail, the fingerprint detection processing disallowed state may be set to a fingerprint detection processing disallowed state regardless of whether the permission conditions and disallowance conditions are met.

[0052] Also, the collation unit 20 may set user authentication using fingerprint authentication as a custom function, and set whether to enable or disable it according to the user's designation. In this case, the above-mentioned permission condition may be limited by being set to enabled as a required condition, and the above-mentioned non-permission condition may be added with an additional alternative condition of being set to disabled. That is, when the fingerprint detection processing non-permission state is set to disabled, the fingerprint detection processing non-permission state may be maintained without fail, and when the fingerprint detection processing permission state is changed from enabled to disabled, the fingerprint detection processing non-permission state may be transitioned without fail. As a result, when the fingerprint detection processing is set to disabled, the fingerprint detection processing is not performed at all, so that the risk of the comfort inside the vehicle being reduced by radio wave noise can be more reliably suppressed.

[0053] Furthermore, in the fingerprint detection processing disallowed state, the matching unit 20 acquires the number of fingerprints registered in the fingerprint authentication unit 12, and if the number of fingerprints is 0, the fingerprint detection processing disallowed state may be maintained regardless of the above-mentioned permission conditions. As a result, if fingerprint authentication is impossible and there is no point in performing the fingerprint detection processing, the fingerprint detection processing is not performed at all, so that the risk of the comfort inside the vehicle being reduced due to radio wave noise can be more reliably suppressed.

[0054] <Effects> According to this embodiment, under a predetermined situation where it is assumed that the fingerprint detection process for fingerprint authentication will not be required, the fingerprint detection process by the fingerprint sensor 11 is suppressed. As a result, even if the user inadvertently touches the fingerprint reading portion of the fingerprint sensor 11, the fingerprint sensor 11 does not execute the fingerprint detection process, so that radio noise is not generated, and it is possible to suppress the risk of a decrease in comfort inside the vehicle, such as a decrease in the sound quality of the radio. Also, under a predetermined situation where it is assumed that the fingerprint detection process for fingerprint authentication will be required, when the user touches the fingerprint reading portion of the fingerprint sensor 11, the fingerprint sensor 11 executes the fingerprint detection process, so that the fingerprint authentication can be performed suitably.

[0055] Although an embodiment of the present invention has been described above, the present invention can be understood as a fingerprint authentication device, a method executed by a computer of the fingerprint authentication device, a program, and a computer-readable non-transitory recording medium storing the same, a system, a vehicle, etc. [Industrial Applicability]
