Description

The present invention relates to a technical field of an authentication processing device capable of authenticating a user (personal authentication) using the biometric information of the user and determining whether or not the physical condition of the user satisfies a standard. ..

Conventionally, for example, a drunk driving prevention device as shown in Patent Document 1 has been proposed. When the driver presses the pressing part of the start switch to start the engine of the vehicle, this drunk driving prevention device irradiates the driver's finger with infrared rays from an infrared light source, and images the finger in this state. Personal authentication is performed using the blood vessel pattern obtained. Then, the drunk driving prevention device detects the alcohol component by the alcohol sensor provided in the start switch when the personal authentication is successful, and starts the vehicle engine only when the alcohol is not detected (). Paragraphs 0049 to 0051, etc.).

For example, when the license confirmation device 1 is mounted on a vehicle, the license confirmation device 1 has an engine control unit that controls the operation of the engine, a steering control unit that controls the operation of the steering wheel, and a shift lever that controls the operation of the shift lever. Communicate with the control unit. The engine control unit, steering control unit, and shift lever control unit may be connected to a gateway device that serves as an interface with the license confirmation device 1.

The biometric sensor 11 is an example of a biometric information acquisition sensor that acquires biometric information for use in authentication of a user who uses the license confirmation device 1 (hereinafter, referred to as “user authentication”). In the present embodiment, the pad of the finger of the user is taken as an example as a part of the body of the user, and the fingerprint of the user (the crest on the pad of the finger) is taken as an example of biological information. The biometric sensor 11 has, for example, tens of thousands of electrodes, a contact surface with which the pad of the user's finger comes into contact, and the like. When the pad of the user's finger comes into contact with the contact surface, the electrode is charged with an amount of electric charge according to the proximity to the contact surface due to the unevenness (that is, the unevenness constituting the fingerprint) on the pad of the user's finger. Accumulate. Then, the biometric sensor 11 detects the amount of electric charge accumulated in each electrode and converts it into a numerical value (that is, a numerical value corresponding to the amount of electric charge) to show biometric information (matrix corresponding to the image) indicating the fingerprint. Is acquired, and the acquired biometric information is transmitted to the secure element 13 via a wiring (not shown).

The alcohol sensor 12 is an example of a state information acquisition sensor that acquires state information indicating the physical condition of the user. In this embodiment, the concentration of alcohol is taken as an example of the state information. The alcohol sensor 12 has a contact surface or the like that the pad of the user's finger comes into contact with. When the pad of the user's finger comes into contact with this contact surface, the alcohol sensor 12 detects fluorescence according to the concentration of the alcohol component contained in the sweat of the user and converts it into a numerical value (a numerical value corresponding to the intensity of fluorescence). By converting, the state information indicating the intensity of the fluorescence is acquired, and the acquired state information is transmitted to the secure element 13 via a wiring (not shown).

FIG. 2A is a plan view showing an example of the internal structure when the license confirmation device 1 is an IC card, and FIG. 2B is an example of the internal structure of the IC card shown in FIG. 2A. It is sectional drawing (cross-sectional view of part XX part) which shows. As shown in FIG. 2B, the IC card is insulated by laminating an insulating sheet 1x on a printing sheet 2x (in the example of FIG. 2B, a printing sheet on the lower side (back side)) as a base material. A print sheet 3x (in the example of FIG. 1B, a print sheet on the upper side (front side)) is laminated on the sheet 1x. That is, the insulating sheet 1x is sandwiched between the two printing sheets 2x and 3x. Such a laminated structure is formed by a method such as spin coating or coating. The insulating sheet 1x is made of, for example, polyimide having a thickness of about 50 μm to 400 μm. The print sheets 2x and 3x are made of, for example, polyethylene terephthalate (PET) or PET-G having a thickness of about 100 μm, respectively. The back side printing 4x is performed on the printing sheet 2x, and the front side printing 5x is performed on the printing sheet 3x.

A biometric sensor 11, an alcohol sensor 12, a secure element 13, and an antenna 14 are mounted on the insulating sheet 1x. In particular, the biometric sensor 11 and the alcohol sensor 12 are arranged side by side on the print sheet 2x so as not to overlap each other in the thickness direction Y of the print sheet 2x. By arranging the biometric sensor 11 and the alcohol sensor 12 side by side on the print sheet 2x in this way, personal authentication (user authentication) and alcohol detection (alcohol component detection) can be performed without the user moving their fingers. Therefore, if each process is continuously performed, the troublesomeness given to the user who is the subject can be reduced. The contact surface 11X of the biometric sensor 11 and the contact surface 12X of the alcohol sensor 12 can be contacted with the pad of the user's finger through the through hole 101 provided in the printing sheet 3x, respectively.

3A and 3B are views showing a state in which the pad of the user's finger is in contact with the contact surface 11X of the biometric sensor 11 and the contact surface 12X of the alcohol sensor 12. As shown in FIG. 2B, the biometric sensor 11 and the alcohol sensor 12 are arranged side by side on the printing sheet 2x (base material) as an IC card as the license confirmation device 1. By arranging the biometric sensor 11 and the alcohol sensor 12 side by side in this way, the user can perform personal authentication (user authentication) and alcohol detection (alcohol component detection) without moving his / her finger. If this is continuously performed, the troublesomeness given to the user who is the subject can be reduced.

Further, in the example of FIG. 2B, since the biometric sensor 11, the alcohol sensor 12, and the secure element 13 are fixedly arranged on the printing sheet 2x, the insulating sheet 1x has through holes from the front surface to the back surface. 102 is provided. A biometric sensor 11, an alcohol sensor 12, and a secure element 13 are incorporated (fitted) into the through hole 102, and are bonded, for example. The biometric sensor 11, the alcohol sensor 12, and the secure element 13 each have a thickness equal to or less than the thickness of the insulating sheet 1x. The thickness of the secure element 13 is usually in the range of about 50 μm to 200 μm. The biometric sensor 11 and the alcohol sensor 12 are electrically connected to the secure element 13 via, for example, a wiring pattern formed on the insulating sheet 1x.

As another example of the method of arranging the biometric sensor 11, the alcohol sensor 12, and the secure element 13, the biometric sensor 11, the alcohol sensor 12 and the biometric sensor 12 are placed on the surface (upper surface or lower surface) of the insulating sheet 1x. , And the secure element 13 may be arranged (eg, arranged by adhesion). In this case, a spacer sheet or the like is laminated on the side where the biometric sensor 11, the alcohol sensor 12, and the secure element 13 protrude (that is, a spacer sheet or the like is provided between the insulating sheet 1x and the printing sheet 2x or 3x. In addition, a through hole capable of absorbing the height of these components is provided in a portion of the spacer sheet or the like where the biometric sensor 11, the alcohol sensor 12, and the secure element 13 come into contact with each other.

The antenna 14 is, for example, a resist formed on an aluminum foil or the like laminated on an insulating sheet 1x, and only the coil shape is left by a photoetching technique. The antenna 14 is formed so as to be wound for several turns on the 1x surface of the insulating sheet. Further, both ends of the coil forming the antenna 14 are electrically connected to the secure element 13 via, for example, a wiring pattern formed on the insulating sheet 1x. When the IC card C is held by the reader / writer RW, electric power is generated in the coil of the antenna 14 by the electromagnetic wave from the reader / writer RW, and the electric power is supplied to the secure element 13. Further, power is supplied from the secure element 13 to the alcohol sensor 12 and the biometric sensor 11 via the wiring pattern. The IC card C is press-laminated, for example, in a state where the insulating sheet 1x on which the biometric sensor 11, the alcohol sensor 12, the secure element 13, and the antenna 14 are mounted and the printing sheets 2x and 3x are laminated. It is generated by.

Next, the details of the configuration and function of the alcohol sensor 12 will be described with reference to FIG. 4 (A) is a plan view showing an example of the internal structure of the alcohol sensor 12, and FIGS. 4 (B) and 4 (C) are cross-sectional views (XX parts) showing an example of the internal structure of the alcohol sensor 12. Cross-sectional view of). As shown in FIGS. 4A and 4B, the alcohol sensor 12 includes an insulating resin material 121, a light-transmitting resin material 122, a dehydrogenase film material 123, an ultraviolet light emitting diode 124, a photosensor 125, and the like. .. Further, the alcohol sensor 12 is formed by laminating a light-transmitting resin material 122 and a dehydrogenase film material 123 on an insulating resin material 121. The insulating resin material 121 is made of, for example, a polyimide having a thickness of 40 μm to 200 μm. The light-transmitting resin material 122 and the dehydrogenase film material 123 have a thickness of about 10 μm to 200 μm, respectively, and the upper surface of the light-transmitting resin material 122 and the dehydrogenase film material 123 is penetrated by the pad of the user's finger. Corresponds to the contact surface that is contacted through the hole 101. The light-transmitting resin material 122 is made of a material that transmits ultraviolet rays from the ultraviolet light emitting diode 124, but does not necessarily have to be provided as a component of the alcohol sensor 12.

An ultraviolet light emitting diode 124 and a photo sensor 125 are attached to the insulating resin material 121. In the example of FIG. 4B, the ultraviolet light emitting diode 124 and the photosensor 125 are incorporated in the same insulating resin material 121 provided on the printing sheet 2x, and in the thickness direction Y of the printing sheet 2x, The light-transmitting resin material 122 is arranged on the ultraviolet light emitting diode 124, and the dehydrogenase film material 123 is arranged on the photosensor 125. However, in the example of FIG. 4B, the light emitting surface 124X of the ultraviolet light emitting diode 124 and the detection surface 125X of the photosensor 125 are not covered with the insulating resin material 121, and the light emitting surface 124X is the light transmitting resin material 122. The detection surface 125X is in contact with the dehydrogenase film material 123. On the other hand, in the example of FIG. 4C, the ultraviolet light emitting diode 124 is arranged on the insulating resin material 121 by, for example, adhesion, and the photosensor 125 is insulated so that its detection surface 125X is not covered by the insulating resin material 121. It is incorporated in the resin material 121, and the dehydrogenase film material 123 is arranged on the photosensor 125 in the thickness direction Y of the base material. In both cases of FIGS. 4 (B) and 4 (C), the ultraviolet light emitting diode 124 and the photo sensor 125 are arranged side by side on the print sheet 2x so as not to overlap each other in the thickness direction of the print sheet 2x.

The ultraviolet light emitting diode 124 receives power from the secure element 13 and emits ultraviolet rays having a wavelength near 340 nm (for example, 300 to 370 nm) from the light emitting surface 124X. The dehydrogenase film material 123 is irradiated with ultraviolet rays from the ultraviolet light emitting diode 124. The dehydrogenase membrane material 123 is produced, for example, by immobilizing a dehydrogenase on a carrier. For the carrier, a chemically stable material is used as a base for fixing the dehydrogenase. The dehydrogenase membrane material may be produced by solidifying the dehydrogenase itself without using a carrier.

Dehydrogenase is an enzyme that catalyzes the reaction of oxidizing alcohol (CH ₃ CH ₂ OH: ethanol) to acetaldehyde (CH ₃ CHO) in the presence of coenzyme. As the dehydrogenase, for example, alcohol dehydrogenase (EC.1.1.1.1, EC.1.1.1.2, EC.1.1.1.71) is used. As the coenzyme, NAD ⁺ (oxidized form of nicotinamide adenine dinucleotide) or NADP ⁺ (oxidized form of nicotinamide adenine dinucleotide phosphate) is used. This coenzyme is provided, for example, on the surface of the dehydrogenase membrane material. By the enzymatic reaction of alcohol, coenzyme, and dehydrogenase, acetaldehyde and NADH (reduced form of nicotinamide adenine dinucleotide) or NADPH (nicotinamide), as shown in the chemical formula (1) or (2) below, A reduced form of adenine dinucleotide phosphate) is produced.

CH ₃ CH ₂ OH + NAD ⁺ → CH ₃ CHO + NADH + H ⁺
... (1)

CH ₃ CH ₂ OH + NADP ⁺ → CH ₃ CHO + NADPH + H ⁺
... (2)

Here, NADH or NADPH is a substance produced in the dehydrogenase membrane material 123 by an alcohol component contained in the user's sweat (for example, sweat sweated from the pad of the user's finger), and depends on the concentration of alcohol. To do. NADH or NADPH emits excited fluorescence by absorbing the ultraviolet rays emitted from the ultraviolet light emitting diode 124. That is, NADH or NADPH absorbs ultraviolet rays in the vicinity of 340 nm to change from the ground state to the excited state and emit fluorescence.

The photosensor 125 is configured to include a photodiode, and detects fluorescence emitted by NADH or NADPH generated in the dehydrogenase film material 123 due to an alcohol component contained in the user's sweat by absorbing ultraviolet rays in the vicinity of 340 nm. Detected through surface 125X. The fluorescence detected in this way is converted into a numerical value as described above, and is transmitted to the secure element 13 via wiring as state information. Since the wavelength of the fluorescence emitted as described above is 450 to 510 nm, a photosensor 125 that detects fluorescence having a wavelength of 450 to 510 nm is adopted.

Next, the details of the configuration and the function of the secure element 13 will be described. The secure element 13 includes a program storage unit 131, a data storage unit 132, a transmission / reception unit 133 to 135, a control unit 136, and the like, and communicates with the control unit 2 via wired or wireless communication and is a biometric sensor. It controls the operation of the 11 and the alcohol sensor 12. The program storage unit 131 and the data storage unit 132 are composed of, for example, at least one of a ROM (Read Only Memory) and an NVM (Non Volatile Memory). Programs such as an OS (operating system) and an application are stored in the program storage unit 131. The data storage unit 132 stores collation data for collation used for user authentication, determination standard data indicating a determination standard (for example, a threshold value) for determining the physical condition of the user, and the like. Here, the biometric information acquired in advance by the biometric sensor 11 is used as the collation data. Therefore, the collation data indicates a fingerprint on the pad of the user's finger.

The transmission / reception unit 133 serves as an interface for communicating with the control unit 2. The transmission / reception unit 134 includes a connection terminal connected to the wiring from the biometric sensor 11, and serves as an interface for communicating with the biometric sensor 11. The transmission / reception unit 135 includes a connection terminal connected to the wiring from the alcohol sensor 12, and serves as an interface for communicating with the alcohol sensor 12.

The control unit 136 (an example of a computer) is composed of a CPU (Central Processing Unit), a RAM (Random Access Memory), a random number generator, and the like, and the control unit 136 stores a program in response to a request from the control unit 2. The license confirmation process is executed according to the program stored in the unit 131. The license confirmation process is a process of confirming whether to grant an operation permission (in other words, grant a license) to the controlled object 3 (that is, perform an operation permission / rejection determination). In the license confirmation process, the control unit 136 includes a sensor control unit 1361 (an example of a sensor control means), an information acquisition unit 1362, a user authentication unit 1363 (an example of a user authentication means), and a state determination unit 1364 (an example of a determination means). And functions as an information transmission unit 1365 (an example of transmission means) and the like.

The sensor control unit 1361 transmits an activation signal to the biometric sensor 11 via the transmission / reception unit 134 in response to the sensor activation request transmitted from the control unit 2. The sensor activation request may be divided into a biometric sensor activation request and an alcohol sensor activation request. The biometric sensor 11 is activated in response to an activation signal from the sensor control unit 1361, so that the amount of electric charge can be detected from the electrodes. Then, the biometric sensor 11 returns a response signal to the sensor control unit 1361 after activation. When the sensor control unit 1361 receives the response signal from the biometric sensor 11, it transmits activation information indicating that the biometric sensor 11 has been activated to the control unit 2 via the transmission / reception unit 133. After that, when the pad of the user's finger is placed on the contact surface of the biometric sensor 11, the biometric sensor 11 detects the amount of electric charge accumulated in the electrode and acquires biometric information indicating a fingerprint, and the acquired biometric information. Is transmitted to the secure element 13 via wiring. As a result, the information acquisition unit 1362 receives (acquires) the biometric information acquired by the biometric sensor 11 via the transmission / reception unit 134.

Further, the sensor control unit 1361 transmits a start signal to the alcohol sensor 12 via the transmission / reception unit 135 in response to the sensor activation request transmitted from the control unit 2. The alcohol sensor 12 is activated in response to an activation signal from the sensor control unit 1361 to emit ultraviolet rays from the ultraviolet light emitting diode 124, and the photo sensor 125 is in a state in which the intensity of fluorescence can be detected. Then, the alcohol sensor 12 returns a response signal to the sensor control unit 1361 after activation. When the sensor control unit 1361 receives the response signal from the alcohol sensor 12, it transmits start information indicating that the alcohol sensor 12 has been activated to the control unit 2 via the transmission / reception unit 133. After that, when the pad of the user's finger is placed on the contact surface of the alcohol sensor 12, the alcohol sensor 12 acquires the state information indicating the intensity of fluorescence detected by the photo sensor 125, and the acquired state information is transmitted via wiring. Is transmitted to the secure element 13. As a result, the information acquisition unit 1362 receives (acquires) the state information acquired by the alcohol sensor 12 via the transmission / reception unit 135.

The user authentication unit 1363 is an execution request transmitted from the control unit 2 that has received the activation information, and is a living body acquired by the biometric sensor 11 in response to an execution request for license confirmation (operation permission / rejection determination) for the control target 3. User authentication is performed using the information. For example, the user authentication unit 1363 collates the fingerprint indicated by the biometric information acquired by the biometric sensor 11 with the fingerprint indicated by the collation data stored in the data storage unit 132, and a plurality of feature points in both fingerprints ( For example, when the end point and the branch point) match a predetermined number or more, it is determined that the user authentication is successful.

The status determination unit 1364 determines the user status using the status information acquired by the alcohol sensor 12 in response to the license confirmation execution request transmitted from the control unit 2 that has received the activation information. For example, the state determination unit 1364 determines whether the fluorescence intensity indicated by the state information (an example of the user's physical condition) is less than the determination standard (in other words, does the user's physical condition satisfy a preset standard). Whether or not it is determined (this is referred to as user status determination). Here, the determination standard is, for example, a threshold value indicated by the determination reference data stored in the data storage unit 132, and if the fluorescence intensity is equal to or higher than the threshold value, it is considered that the alcohol concentration exceeds the reference value.

In the information transmission unit 1365, the user authentication by the user authentication unit 1363 is successful, and the fluorescence intensity indicated by the state information is less than the determination standard by the state determination unit 1364 (that is, the physical condition of the user is preset. When it is determined that the control target 3 is satisfied with the above criteria), the information indicating the license validity for the control target 3 (that is, the information indicating the operation permission for the control target 3) is transmitted (response) to the control unit 2 via the transmission / reception unit 133. ..

FIG. 6 is a flowchart showing an example of the license confirmation process executed by the control unit 136.

In FIG. 5, for example, when the power supply to the control unit 2 is started by turning on the power, the control unit 2 transmits a reset (signal) to the license confirmation device 1 (step S1). When the control unit 136 of the license confirmation device 1 receives the reset from the control unit 2, the control unit 136 transmits a reset response to the control unit 2 via the transmission / reception unit 133 (step S2).

Next, when the control unit 2 receives the reset response from the license confirmation device 1, it transmits a biometric sensor activation request to the license confirmation device 1 (step S3). When the control unit 136 (sensor control unit 1361) of the license confirmation device 1 receives the biometric sensor activation request from the control unit 2, the biometric sensor 11 passes through the transmission / reception unit 134 in response to the biometric sensor activation request. Send a start signal to. Then, when the control unit 136 (sensor control unit 1361) receives the response signal from the biometric sensor 11, it transmits the activation information indicating that the biometric sensor 11 has been activated to the control unit 2 via the transmission / reception unit 133. (Step S4).

Next, when the control unit 2 receives the activation information (activation information indicating that the biometric sensor 11 has been activated) from the license confirmation device 1, it transmits an alcohol sensor activation request to the license confirmation device 1 (step S5). .. When the control unit 136 (sensor control unit 1361) of the license confirmation device 1 receives the alcohol sensor activation request from the control unit 2, the activation signal is sent to the alcohol sensor 12 via the transmission / reception unit 135 in response to the alcohol sensor activation request. To send. Then, when the control unit 136 (sensor control unit 1361) of the license confirmation device 1 receives the response signal from the alcohol sensor 12, the control unit 2 transmits activation information indicating that the alcohol sensor 12 has been activated via the transmission / reception unit 133. (Step S6).

The order of the processes of steps S3 and S4 and the processes of steps S5 and S6 may be reversed. Alternatively, the control unit 136 (sensor control unit 1361) may perform the processes of steps S4 and S6 in response to the sensor activation request in which the biometric sensor activation request and the alcohol sensor activation request are integrated.

Next, when the control unit 2 receives the activation information (the activation information indicating that the alcohol sensor 12 has been activated) from the license confirmation device 1, the control unit 2 transmits the license confirmation request to the license confirmation device 1 (step S7). When the control unit 136 of the license confirmation device 1 receives the license confirmation request from the control unit 2, the license confirmation process (step S8) shown in FIG. 6 is started.

When the license confirmation process shown in FIG. 6 is started, the control unit 136 executes the user authentication process (step S81). In the user authentication process, the control unit 136 (information acquisition unit 1362) acquires the biometric information acquired by the activated biometric sensor 11 via the transmission / reception unit 134. Next, the control unit 136 (user authentication unit 1363) performs user authentication using the acquired biometric information. For example, the control unit 136 (user authentication unit 1363) collates the fingerprint indicated by the acquired biometric information with the fingerprint indicated by the collation data stored in the data storage unit 132, and determines a plurality of feature points in both fingerprints. Determine if there are more than a few matches. When a plurality of feature points on both fingerprints match a predetermined number or more, the control unit 136 (user authentication unit 1363) determines that the user authentication is successful and stores information indicating the user authentication success (for example, the user). Turn on (1) the flag that indicates successful authentication). On the other hand, when a plurality of feature points on both fingerprints do not match a predetermined number or more, the control unit 136 (user authentication unit 1363) determines that the user authentication has failed and stores information indicating the user authentication failure (for example, the user). Turn off (0) the flag indicating successful authentication).

Next, the control unit 136 executes the user state determination process (step S82). In the user state determination process, the control unit 136 (information acquisition unit 1361) acquires state information indicating the fluorescence intensity detected by the activated alcohol sensor 12 via the transmission / reception unit 135. Next, the control unit 136 (state determination unit 1364) uses the state information obtained from the finger on which the contact surface 12X of the alcohol sensor 12 is detected, and the state information acquired by the alcohol sensor 12 is used. Judge the user status. For example, the control unit 136 (state determination unit 1364) determines whether or not the fluorescence intensity indicated by the acquired state information is less than the determination standard. Then, when the control unit 136 (state determination unit 1364) determines that the fluorescence intensity is less than the determination standard (that is, determines that the user condition is good), the control unit 136 stores information indicating that the user condition is good (for example, the user condition is good). Turn on (1) the flag indicating. On the other hand, when the control unit 136 (state determination unit 1364) determines that the fluorescence intensity is not less than the determination standard, the control unit 136 stores information indicating a user condition defect (for example, the flag indicating the user condition good condition is set to off (0)). ). The user status determination process may be executed immediately before the user authentication process.

Next, the control unit 136 determines whether or not the user authentication is successful and the user state is good (step S83). In step S81, it is determined that the user authentication is successful (that is, the information indicating that the user authentication is successful is stored), and in step S82, it is determined that the user state is good (that is, the information indicating that the user state is good is stored). It is determined whether or not. When the control unit 136 determines that the user authentication is successful and the user condition is good (step S83: YES), the control unit 136 stores the information indicating the license validity (license validity record) (step S84), and performs the license confirmation process. It ends and returns to the process of FIG. On the other hand, when the control unit 136 determines that the user authentication has failed or the user status is not good (step S83: NO), the control unit 136 stores information indicating license invalidity (license invalidation record) (step S85), and ends the license confirmation process. Then, the process returns to FIG.

Returning to the process of FIG. 5, the control unit 136 (information transmission unit 1365) controls information indicating license validity or license invalidity as a license confirmation result (operation permission / rejection determination result) for the license confirmation request via the transmission / reception unit 133. Transmission (response) to unit 2 (step S9).

When the control unit 2 receives the license confirmation result from the license confirmation device 1, it transmits a biometric sensor stop request to the license confirmation device 1 (step S10). When the control unit 136 (sensor control unit 1361) of the license confirmation device 1 receives the biometric sensor stop request from the control unit 2, the biometric sensor 11 passes through the transmission / reception unit 134 in response to the biometric sensor stop request. Send a stop signal to. The biometric sensor 11 returns a response signal to the control unit 136 (sensor control unit 1361) in response to the stop signal from the control unit 136 (sensor control unit 1361), and stops the operation. Then, when the control unit 136 (sensor control unit 1361) receives the response signal from the biometric sensor 11, it transmits stop information indicating that the biometric sensor 11 has stopped to the control unit 2 via the transmission / reception unit 133. (Step S11).

Next, when the control unit 2 receives the stop information (stop information indicating that the biometric sensor 11 has stopped) from the license confirmation device 1, it transmits an alcohol sensor stop request to the license confirmation device 1 (step S12). .. When the control unit 136 (sensor control unit 1361) of the license confirmation device 1 receives the alcohol sensor stop request from the control unit 2, the stop signal is sent to the alcohol sensor 12 via the transmission / reception unit 135 in response to the alcohol sensor stop request. To send. The alcohol sensor 12 returns a response signal to the control unit 136 (sensor control unit 1361) in response to the stop signal from the control unit 136 (sensor control unit 1361), and stops the operation. Then, when the control unit 136 (sensor control unit 1361) receives the response signal from the alcohol sensor 12, it transmits stop information indicating that the alcohol sensor 12 has stopped to the control unit 2 via the transmission / reception unit 133 (step). S13).

Then, when the license confirmation result from the license confirmation device 1 indicates that the license is valid, the control unit 2 starts the operation of the control target 3 by transmitting a drive signal (that is, an operation permission signal) to the control target 3. Let me. For example, when the control unit 2 is an engine control unit, the engine is started by transmitting a start signal indicating engine start to the control target 3. On the other hand, for example, when the control unit 2 is a steering control unit or a shift lever control unit, the steering or shift lever is unlocked by transmitting an unlock signal to the control target 3. On the other hand, for example, when the control unit 2 is a gateway device, a drive signal is transmitted to the engine control unit, and an unlock signal is transmitted to the steering control unit and the shift lever control unit. On the other hand, when the control unit 2 is a lock / unlock control unit that controls the locking / unlocking of the door, the door is unlocked by transmitting an unlocking signal to the control target 3.

On the other hand, when the license confirmation result from the license confirmation device 1 indicates that the license is invalid, the control unit 2 transmits a lock signal (that is, an operation disapproval signal) or an error signal to the control target 3 to control the control target 3. Lock the operation of. For example, when the control unit 2 is an engine control unit, the drive signal is not transmitted to the control target 3. On the other hand, for example, when the control unit 2 is a steering control unit or a shift lever control unit, the steering or shift lever is locked by transmitting a lock signal to the control target 3. On the other hand, for example, when the control unit 2 is a gateway device, a lock signal is transmitted to the steering control unit and the shift lever control unit. On the other hand, when the control unit 2 is a lock / unlock control unit that controls the lock / unlock of the door, the unlock signal is not transmitted to the control target 3. When the control unit 2 is a control unit that controls the alarm output circuit, an error signal is transmitted to the control target 3 to output an alarm.

As described above, according to the above embodiment, the license confirmation device 1 activates the biometric sensor 11 and the alcohol sensor 12 in response to the sensor activation request transmitted from the control unit 2, and the biometric sensor 11 and the alcohol sensor 12 are activated. Activation information indicating that the alcohol sensor 12 has been activated is transmitted to the control unit 2, and user authentication is performed using the biometric information acquired by the biometric sensor 11 in response to the execution request transmitted from the control unit 2. The user status is determined using the status information acquired by the alcohol sensor 12, and when the user authentication is successful and the user status is determined to be good, the control unit 2 outputs information indicating that the license for the control target 3 is valid. Since it is configured to transmit to, it is possible to reliably perform user authentication and user status determination for the same person, and it is possible to more reliably prevent omission of detection.

[3. Application example of license confirmation process]
Next, an application example of the above-mentioned license confirmation process will be described with reference to FIG. 7. FIG. 7A is a flowchart showing an application example of the license confirmation process executed by the control unit 136. The license confirmation process shown in FIG. 7A is a process capable of preventing detection omission more reliably than the license confirmation process shown in FIG. 6, and in this application example, in step S8 shown in FIG. 5, FIG. Instead of the license confirmation process shown, the license confirmation process shown in FIG. 7A is executed. In the license confirmation process shown in FIG. 7A, the biometric sensor 11 acquires biometric information a plurality of times at different timings, and the user authentication unit 1363 uses each biometric information acquired by the biometric sensor 11 to use the user. Is performed a plurality of times at different timings, and the state determination unit 1364 is configured to perform a user state determination using the state information acquired by the alcohol sensor 12 during the plurality of user authentications. The contents of the user authentication processes 1 to 3 shown in steps S91, S93, and S95 shown in FIG. 7A are the same as the user authentication processes shown in step S81, and the user authentication processes 1 to 3 are different from each other. It is executed at the timing. Further, the contents of the user state determination processes 1 to 3 shown in steps S92, S94, and S96 shown in FIG. 7A are the same as the user state determination process shown in step S82, and the user state determination processes 1 to 3 are , Are executed at different timings.

Then, the control unit 136 determines whether or not the user authentication is successful in all of steps S91, S93, and S95, and it is determined that the user state is good in all of steps S92, S94, and S96. Determine (step S97). When it is determined that the user authentication is successful in all of steps S91, S93, and S95, and it is determined that the user state is good in all of steps S92, S94, and S96 (step S97: YES), the control unit. 136 stores the information indicating the license validity (license validity record) (step S98), and ends the license confirmation process. On the other hand, when the control unit 136 determines that the user authentication has failed in any of the user authentication processes 1 to 3 or that the user state is not good in any of the user state determination processes 1 to 3 (step S97: NO). The information indicating the license invalidity is stored (license invalidation record) (step S99), and the license confirmation process is completed. That is, if a user state determination process is inserted between each user authentication process and it is determined that the user state is not good in any of the user state determination processes, the license is invalidated. If the user authentication process is divided in this way, if the user releases his / her finger after the user authentication, there is a high possibility that the next user authentication process will fail, so that it becomes difficult to avoid the user state determination process. .. For example, if a user who is a driver moves his / her finger away from the alcohol sensor 12 to prevent alcohol from being detected, the degree of matching of a plurality of feature points in the fingerprint is dramatically reduced, and there is a dramatic possibility that the user authentication process will fail. In such a case, it is possible to prevent the engine of the vehicle from starting.

In addition, in FIG. 7A, the processing of steps S94 to S96 may be omitted. In this case, if it is determined in steps S91 and S93 that the user authentication is successful, and if it is determined in step S92 that the user state is good, the control unit 136 stores information indicating that the license is valid. Further, the authentication algorithm (authentication method) may be different in a plurality of user authentications. In this case, for example, in the user authentication process 1 of step S91, the user authentication unit 1363 collates the fingerprint indicated by the acquired biometric information with the fingerprint indicated by the collation data, and a plurality of feature points (for example,) in both fingerprints. , End point and branch point) match a predetermined number or more (that is, the degree of coincidence of feature points) is determined. On the other hand, in the user authentication process 2 in step S93, the user authentication unit 1363 collates the fingerprint indicated by the acquired biometric information with the fingerprint indicated by the collation data in addition to the degree of matching of the feature points, and both fingerprints are collated. It is determined whether or not a plurality of ridges (lines crossing between feature points) in the above match a predetermined number or more. As a result, the time required for each user authentication can be made different, so that it is possible to make it difficult to avoid the user state determination process.

Further, the fingerprints of different parts may be configured to be different in a plurality of user authentications, which also makes it difficult to avoid the user state determination process. FIG. 7B is a diagram showing an example in which the fingerprint region is divided into two parts, and FIG. 7C is a diagram showing an example in which the fingerprint area is divided into three parts. In the examples of FIGS. 7 (B) and 7 (C), the fingerprint area is divided in the vertical direction, but it may be divided in the horizontal direction. The example of FIG. 7B is an example in which the processes of steps S94 to S96 are omitted. In this case, the user authentication unit 1363 is the part X indicated by the acquired biometric information in the user authentication process of step S91. And the fingerprint of the part X indicated by the collation data are collated to determine whether or not a predetermined number or more of the plurality of feature points in both fingerprints match, and the plurality of feature points in both fingerprints are a predetermined number. If the above matches, it is determined that the user authentication is successful. Further, in the user authentication process of step S93, the user authentication unit 1363 collates the fingerprint of the part Y indicated by the acquired biometric information with the fingerprint of the part Y indicated by the collation data, and a plurality of feature points in both fingerprints are obtained. It is determined whether or not a predetermined number or more match, and if a plurality of feature points on both fingerprints match a predetermined number or more, it is determined that the user authentication is successful.

The example of FIG. 7C is an example in which the processes of steps S94 to S96 are not omitted. In this case, the user authentication unit 1363 is the part X indicated by the acquired biometric information in the user authentication process 1 of step S91. And the fingerprint of the part X indicated by the collation data are collated to determine whether or not a predetermined number or more of the plurality of feature points in both fingerprints match, and the plurality of feature points in both fingerprints are a predetermined number. If the above matches, it is determined that the user authentication is successful. Further, in the user authentication process 2 of step S93, the user authentication unit 1363 collates the fingerprint of the part Y indicated by the acquired biometric information with the fingerprint of the part Y indicated by the collation data, and a plurality of feature points in both fingerprints. Is determined to match a predetermined number or more, and if a plurality of feature points on both fingerprints match a predetermined number or more, it is determined that the user authentication is successful. Further, in the user authentication process 3 of step S95, the user authentication unit 1363 collates the fingerprint of the part Z indicated by the acquired biometric information with the fingerprint of the part Z indicated by the collation data, and a plurality of feature points in both fingerprints. Is determined to match a predetermined number or more, and if a plurality of feature points on both fingerprints match a predetermined number or more, it is determined that the user authentication is successful.

Further, the area of the finger portion may be randomly different in a plurality of user authentications, which also makes it difficult to avoid the user state determination process. In this case, for example, the user authentication unit 1363 uses random numbers to determine the proportion (for example, 40%) of the portion of the entire finger pad (100%), and the fingerprint of the portion of the determined proportion and the collation data. It is determined whether or not a plurality of feature points in both fingerprints match a predetermined number or more by collating the fingerprints indicated by If they match, it is determined that the user authentication is successful.

In the above embodiment, the biometric sensor 11 is configured to acquire the fingerprint of the user as biometric information, but it may be configured to acquire the crest (palm crest) on the palm of the user as biometric information. Good. In this case, the user authentication unit 1363 collates the palm print indicated by the biometric information acquired by the biometric sensor 11 with the palm print indicated by the collation data stored in the data storage unit 132, and a plurality of feature points in both palm prints. If is more than a predetermined number, it is determined that the user authentication is successful. Also in this case, by applying the above application example, the user authentication unit 1363 may perform user authentication a plurality of times using the palm print indicated by the biometric information acquired by the biometric sensor 11. Further, the user authentication unit 1363 may use the palm prints of different parts in a plurality of user authentications.

Alternatively, the biometric sensor 11 may be configured to acquire a blood vessel (vein) pattern (image) in the user's palm or finger as biometric information. In this case, the biometric sensor 11 includes an infrared light emitting unit and a blood vessel imaging unit, and the blood vessel pattern (image) is obtained by imaging the finger with the imaging unit in a state where the infrared light emitting unit irradiates the palm or the finger. Acquired as biometric information. Then, the user authentication unit 1363 collates the blood vessel pattern indicated by the biometric information acquired by the biometric sensor 11 with the blood vessel pattern indicated by the matching data stored in the data storage unit 132, and a plurality of blood vessel patterns in both blood vessel patterns. If the feature points match a predetermined number or more, it is determined that the user authentication is successful. Also in this case, by applying the above application example, the user authentication unit 1363 may perform user authentication a plurality of times using the blood vessel pattern indicated by the biometric information acquired by the biometric sensor 11. Further, the user authentication unit 1363 may use blood vessel patterns of different sites in a plurality of user authentications. Alternatively, the biometric sensor 11 may be configured to photograph the user's face and acquire it as biometric information. Then, the user authentication unit 1363 collates the face image indicated by the biometric information acquired by the biometric sensor 11 with the face image indicated by the matching data stored in the data storage unit 132, and a plurality of face images in both face images. If the feature points match a predetermined number or more, it is determined that the user authentication is successful.

Further, in the above embodiment, the alcohol sensor 12 is configured to acquire state information showing fluorescence according to the concentration of alcohol, but is made of oxidized tin, for example, as disclosed in Japanese Patent Application Laid-Open No. 2008-308037. By using a semiconductor type gas sensor, it may be configured to acquire the "resistance value of tin oxide" according to the concentration of alcohol as state information. In this case, the state determination unit 1364 is the state information obtained from the finger on which the contact surface 12X of the alcohol sensor 12 is detected, and the resistance value indicated by the state information acquired by the alcohol sensor 12 is the data. If it is less than the threshold value indicated by the determination standard data stored in the storage unit 132 in advance, it is determined that the physical condition of the user satisfies the preset standard (that is, it is determined that the user condition is good).

Further, in the above embodiment, the concentration of the alcohol component has been described as an example of the state information indicating the state of the user's body. For example, the substrate disclosed in JP-A-2009-168671 (the substrate of the dehydrogenase). It may be the concentration of the component. In this case, the state information acquisition sensor acquires the state information obtained from the finger or palm in contact with the contact surface of the state information acquisition sensor and indicates the concentration of the above component, and obtains the state information. It is transmitted to the secure element 13. Then, if the concentration of the above component is less than the threshold value indicated by the determination reference data stored in advance in the data storage unit 132, the state determination unit 1364 determines that the user's physical condition satisfies the preset standard ( That is, it is determined that the user condition is good). Alternatively, the pulse rate of the user may be used as another example of the state information indicating the physical state of the user. In this case, the state information acquisition sensor acquires the state information obtained from the finger or palm in contact with the contact surface of the state information acquisition sensor and indicates the pulse rate of the user, and obtains the state information. It is transmitted to the secure element 13. Then, the state determination unit 1364 determines that the user's physical condition satisfies the preset standard if the pulse rate of the user is less than the threshold value indicated by the determination reference data stored in the data storage unit 132 in advance ( That is, it is determined that the user condition is good). The state information indicating the state of the user's body may be the body temperature of the user. In this case, the state information acquisition sensor acquires the state information obtained from the finger or palm in contact with the contact surface of the state information acquisition sensor and indicates the user's body temperature, and secures the state information. Send to element 13. Then, if the body temperature is less than the threshold value indicated by the determination reference data stored in the data storage unit 132 in advance, the state determination unit 1364 determines that the user's physical condition satisfies the preset standard (that is,). Judge that the user condition is good).
