In FIG. 1B and FIG. 2B, the flow of main signals and information is indicated by arrows. Furthermore, “A to B” indicating a numerical range is used in the meaning of A or more and B or less.

  The biometric information sensor device 1 is configured to read biometric information to be detected, for example, and perform authentication with a registered biometric information template. The detection target of the present embodiment is a user's operation finger. The biometric information to be read is the fingerprint of the operation finger. The biometric information is not limited to the fingerprint of the operation finger, but may be an operation finger or a palm vein. In FIG. 1C, as an example, the read fingerprint of the user, that is, the read biometric information 26 of the user is illustrated.

  The biometric information sensor device 1 registers the biometric information of the user in advance, and performs authentication by comparing the registered biometric information with the read biometric information. The biological information sensor device 1 according to the present embodiment reduces the operation load at the time of registration.

  Specifically, the biological information sensor device 1 controls the biological information sensor 2 that reads the biological information 26 to be detected in contact with the reading surface 20, for example, as shown in FIGS. 1 (a) to 1 (c). When the biometric information 26 is registered and the registered biometric information 33 used for authentication is generated, while the detection target contact with the reading surface 20 is detected, the moving biometric information 26 of the detection target is continuously read. The control unit 3 for generating the registered biometric information 33 is schematically configured.

Since the control unit 3 continuously reads the biological information 26 to be detected that is in contact with the reading surface 20 after reading the biological information 26, the position of the detection target with respect to the reading surface 20 is maintained while keeping the contact. and it is configured to output notification information S ₃ for informing so as to move to.

  In addition, after the position of the detection target with respect to the reading surface 20 changes, the control unit 3 reads the biological information 26 from the new position when the position of the detection target with respect to the reading surface 20 does not change again for a predetermined period. It is configured. This predetermined period is, for example, a stationary period 34 shown in FIG.

  And the control part 3 is comprised so that the registration biometric information 33 may be produced | generated based on the some biometric information 26 read in the state which maintained the contact.

  The biological information sensor device 1 of the present embodiment is schematically configured to include a biological information sensor 2 and a control unit 3 as shown in FIG. 1B, for example.

  Moreover, the biometric information sensor device 1 of this Embodiment is mounted in the vehicle as an example. The biological information sensor device 1 is disposed, for example, in a start switch that instructs driving of a vehicle drive device. And the biometric information sensor apparatus 1 alert | reports using the vehicle communication system 8 which enables mutual communication of the vehicle-mounted apparatus mounted in the vehicle, for example, as shown in FIG.2 (b).

  As an example, the vehicle communication system 8 includes a vehicle LAN (Local Area Network) 80, a vehicle control unit 81, a main monitor 82, a sub monitor 83, an electronic device 84, as shown in FIG. Is generally configured.

  The vehicle LAN 80 is, for example, a vehicle network such as a CAN (Controller Area Network) or a LIN (Local Interconnect Network) that enables mutual exchange of signals and information by wire and wireless. For example, the vehicle control unit 81 is configured to control the vehicle communication system 8.

  The main monitor 82 is disposed, for example, on the center console of the vehicle and displays a map, various menus, and the like. Further, the sub monitor 83 is disposed, for example, on an instrument panel of the vehicle, and displays instruments, the remaining amount of fuel, and the like. The electronic device 84 is, for example, a sheet driving device, an air conditioner, a mirror driving device, or the like.

  For example, when informing the biological information sensor device 1 to move the position of the operation finger 9 with respect to the reading surface 20 while maintaining contact, the biological information sensor device 1 displays a message as a notification on at least one of the main monitor 82 and the sub monitor 83. . The notification method is not limited to the message display, and may be a method using sound, light, vibration, or the like, or a combination of message display, sound, light, vibration, or the like. .

Electronic device 84, for example, to perform the settings that the user authentication is successful based on the authentication information S ₂ is registered. For example, when the electronic device 84 is a sheet driving device, the sheet is driven to the sheet position registered by the user. For example, when the electronic device 84 is an air conditioner, settings such as a set temperature and an air volume registered by the user are performed. Further, for example, when the electronic device 84 is a mirror driving device, the mirror is driven to a position registered by the user.

Also when the biometric information sensor device 1 is disposed on the start switch, the vehicle control unit 81, for example, to instruct the driving of the vehicle engine and the motor based on the authentication information S ₂ output from the biometric information sensor device 1 .

(Configuration of biological information sensor 2)
The biological information sensor 2 is a capacitive sensor as described above. For example, as shown in FIG. 1A, the biological information sensor 2 reads a fingerprint, that is, biological information 26 from an operation finger 9 that is in contact with a reading surface 20 provided on the main body 10.

  As a modification, the biological information sensor 2 may be, for example, a sensor configured to read a fingerprint such as an optical type, a pressure-sensitive type, and a thermal type. Further, the biological information sensor 2 may be a sensor configured to read, for example, a palm print of a palm. Furthermore, the biological information sensor 2 may be configured to read an operating finger or a palm vein as the biological information 26. For example, reading of the vein is performed using a sensor configured to read the vein pattern based on the reflection of the irradiated near infrared rays. The biological information sensor 2 may be a sensor that combines these.

  As another modification, the biological information sensor device 1 may be configured to include, for example, a sensor that detects contact with the reading surface 20 and a sensor that reads the biological information 26. The sensor that detects contact is, for example, a sensor that detects a load applied to the reading surface 20 or a sensor that detects contact with the reading surface 20 by imaging or the like.

  For example, the biological information sensor 2 includes a plurality of detection electrodes 21 arranged in a matrix below the reading surface 20 as shown in FIG. As an example, the plurality of detection electrodes 21 are formed from several tens of thousands to hundreds of thousands, and are arranged at intervals of several μm to several tens of μm.

  For the reading surface 20, for example, XY coordinates with the origin at the upper left of the paper surface of FIG. For example, when the X-axis direction is a row, the biological information sensor 2 reads all the capacitances of the detection electrodes 21 arranged in a row, and then repeats reading the capacitance of the detection electrodes 21 by changing the rows. The detection electrode 21 is scanned. As an example, the scanning period is about 100 ms.

Biometric information sensor 2, for example, to generate an electrostatic capacity information S ₁ is information of a plurality of capacitive read by scanning outputs to the control unit 3. The capacitance information S ₁ is, for example, information of the capacitance of one period. Specifically, the biological information sensor 2 divides, for example, a capacitance greater than or equal to a predetermined threshold value into “1”, a capacitance lower than the threshold value as “0”, and the detection electrode 21. in association with the position to generate the electrostatic capacitance information S _1.

Read image 25 shown in FIG. 1 (c), as an example, the black position detection electrode 21 of "1" on the basis of the capacitance information S _1, which was white the position of the detection electrode 21 of the "0" It is. The circles in the figure are added to indicate feature points 27 described later.

  The position where the electrostatic capacity is high is the position of the crest of the fingerprint and the distance to the detection electrode 21 is short, so that the electrostatic capacity becomes high. The low position is the position of the valley of the fingerprint, the distance to the detection electrode 21 is long, and the capacitance is low. Therefore, if the high capacitance position is black and the low position is white, a read image 25 as shown in FIG. 1C is obtained as an example.

  The read image 25 is similar to the reading surface 20, and an xy coordinate system is set corresponding to the XY coordinate system. Then, the image shown in black in the read image 25 becomes the biometric information 26 read.

(Configuration of control unit 3)
The control unit 3 includes, for example, a CPU (Central Processing Unit) that performs operations and processes on acquired data according to a stored program, a RAM (Random Access Memory) that is a semiconductor memory, a ROM (Read Only Memory), and the like. Microcomputer. In this ROM, for example, a program for operating the control unit 3, a contact threshold value 30, a similarity threshold value 31, a reading threshold value 32, registered biometric information 33, and a stationary period 34 are stored. , Is stored. For example, the RAM is used as a storage area for temporarily storing calculation results and the like.

The contact threshold value 30 is a threshold value for determining contact of the operation finger 9 with the reading surface 20. As an example, when the number of the detection electrodes 21 taking the above-described value “1” based on the capacitance information S ₁ is equal to or greater than the contact threshold value 30, the control unit 3 moves the operation finger 9 to the reading surface 20. It is determined that the contact has been made.

Note the controller 3 as a modification, for example, if the capacitance information S ₁ is was information associated with the position of the electrostatic capacitance detecting electrode 21, the contact threshold 30 is the capacitance threshold The configuration may be such that the contact is determined based on the number of detection electrodes 21 that are defined as values and have a capacitance equal to or greater than the contact threshold 30, but is not limited thereto.

For example, the control unit 3 performs an extraction process on the capacitance information S ₁ to extract the feature points 27. This extraction process is, for example, a ridge extraction process.

  The feature points 27 are, for example, a center point, a branch point, an end point, and a delta as shown in FIG. 1C, but are not limited thereto. The center point is a point that becomes the center of the fingerprint. A branch point is a point where the ridges of the fingerprint are branched. An end point is a point where a ridge is broken. A delta is a collection of ridges from three directions.

  For example, the control unit 3 extracts these feature points 27 and generates an extracted image that is an image of the extracted feature points 27. The registered biometric information 33 is, for example, information in which a template that is a registered extracted image is associated with registered user information.

The control unit 3 compares the template of the registered biometric information 33 with the extracted image obtained from the read biometric information 26, and calculates the similarity based on the position of the feature point 27, the distance between the feature points 27, and the like. Then, the control unit 3, the degree of similarity may was similarity threshold 31 or more, and outputs the authentication information S ₂ as the authentication of the biological information 26 is satisfied.

  As an example, the similarity threshold 31 is 80%. That is, for example, when the number of feature points 27 used for authentication is 80, the control unit 3 determines that the user is a registrant if 64 or more feature points 27 match. The coincidence includes coincidence such as the position of the feature point 27 and the distance between the feature points 27.

  The reading threshold value 32 is a threshold value used when the registered biometric information 33 is generated from the biometric information 26. The reading threshold value 32 is a threshold value of the number of feature points 27 obtained from the read biological information 26, for example. For example, the control unit 3 reads the biometric information 26 and extracts the feature points 27. When the number of extracted feature points 27 is smaller than the reading threshold value 32, the control unit 3 notifies the reading of the biometric information 26 at a new position.

As a modification, the reading threshold value 32 may be defined as, for example, the area or ratio of the read biological information 26 with respect to the read image 25. That is, when generating the registered biometric information 33, the control unit 3 notifies the reading of the biometric information 26 at a new position if the area of the read biometric information 26 is smaller than 70% or 80% of the read image 25. As an example, this area is calculated as the number of detection electrodes 21 having the above-described value “1” based on the capacitance information S ₁ , but is not limited thereto.

The stationary period 34 is a threshold value used for reading the biological information 26 at a new position as described above. The control unit 3 monitors the movement of the operation finger 9 based on the capacitance information S ₁ output from the biological information sensor 2, and if the operation finger 9 after moving has been stationary for a stationary period 34 or more, registration is performed. The biometric information 26 is acquired in order to generate the biometric information 33. The stationary period 34 is, for example, 1 to 2 seconds.

Thus the control unit 3 is configured capacitance information S ₁ that is periodically outputted from the biometric information sensor 2 as time series stored. A control unit 3 reads the biometric information 26 includes, for example, be selected from the capacitance information S ₁ which is the stored obtained biometric information 26.

Generation of Registered Biometric Information 33 FIGS. 3A to 3C are schematic diagrams for explaining an example of biometric information registration by the biometric information sensor device according to the embodiment. FIG. 4A to FIG. 4C are schematic diagrams illustrating an example of biological information read by the biological information sensor device according to the embodiment, and FIG. 4D is an overlay of the read biological information. It is the schematic which shows an example of the registered biometric information. FIG. 3A to FIG. 3C show, as an example, a cross section cut along the line AA shown in FIG. In the following, it is assumed that the notification is made via the main monitor 82, but the present invention is not limited to this.

  As described above, the control unit 3 controls the biometric information sensor 2 that reads the biometric information 26 to be detected in contact with the reading surface 20, and registers the biometric information 26 to generate the registered biometric information 33 used for authentication. When the contact of the detection target with respect to the reading surface 20 is detected, the biometric information 26 is registered according to the registration method in which the biometric information 26 of the moving detection target is continuously read and the registered biometric information 33 is generated.

  Hereinafter, an example of generation of the registered biometric information 33 will be described. The biological information sensor device 1 is in a registration mode for registering the biological information 26. This registration mode is executed, for example, by selecting and determining an icon displayed on the main monitor 82.

  As shown in FIG. 3A, when the user touches the operation finger 9 to the center of the reading surface 20, for example, as shown in FIG. Read.

Control unit 3, when the number of feature points 27 of the biometric information 26 shown in FIG. 4 (a) less than the read threshold value 32, and generates and outputs broadcast information S _3. The main monitor 82, for example, as shown in FIG. 2 (c), "was able to read. Please directly move your finger." On the display screen 820 based on the broadcast information S ₃ while keeping the contact, such as A message 821 is displayed as a notification for moving the position of the operation finger 9 relative to the reading surface 20.

  As shown in FIG. 3 (b), the user tilts the operation finger 9 in the left direction on the paper surface of FIG. When it becomes 34 or more, the control unit 3 reads the biological information 26. As a result, the control unit 3 obtains biometric information 26 near the left side of the read image 25, for example, as shown in FIG.

For example, when the number of feature points 27 of the biological information 26 including the biological information 26 shown in FIGS. 4A and 4B is smaller than the reading threshold value 32, the control unit 3 again notifies information S _3. Is output. Then, the main monitor 82 displays the message 821 again.

  Subsequently, as shown in FIG. 3C, the user tilts the operation finger 9 in the right direction on the paper surface of FIG. 3C while keeping the operation finger 9 in contact with the reading surface 20 according to the message 821. When the stationary period is 34 or more, the control unit 3 reads the biological information 26. As a result, the control unit 3 obtains biometric information 26 near the right side of the read image 25 as shown in FIG. 4B, for example.

  Then, for example, when the number of feature points 27 of the biological information 26 including the biological information 26 shown in FIGS. The registered biometric information 33 is generated. FIG. 4D shows registered biometric information 33 obtained by synthesizing the biometric information 26 shown in FIGS. 4A to 4C.

  The biometric information 26 is synthesized so that, for example, a part of the fingerprint pattern is matched by translation and rotation in the xy plane of the read image 25. As an example, this synthesis is performed based on the fingerprint pattern of the biological information 26 read first.

  Below, an example of operation | movement of the biometric information sensor apparatus 1 of embodiment is demonstrated according to the flowchart of FIG. The case where the biometric information sensor device 1 is in a registration mode in which the user registers biometric information 26 will be described.

(Operation)
Control unit 3 of the body-information sensor device 1 and enters the registration mode, and outputs the broadcast information S ₃ prompting the user contact (Step1). The main monitor 82 acquires the broadcast information _{S 3} via the vehicle LAN 80, and displays a message 821 prompting the contact.

The control unit 3 monitors the contact with the reading surface 20 based on the capacitance information S ₁ periodically output from the biological information sensor 2 and the contact threshold 30. When “Yes” in Step 2 is established, that is, when contact with the reading surface 20 is detected (Step 2: Yes), the control unit 3 reads the biological information 26 in the subsequent cycle (Step 3).

  When “Yes” in Step 4 is established, that is, when the operation finger 9 is stationary for at least the rest period 34 and the reading of the biometric information 26 is completed (Step 4: Yes), the biometric information 26 read up to now is determined. Based on the reading threshold value 32, it is determined whether the registered biometric information 33 can be generated.

Control unit 3, when it is not generating the registered biometric information 33 (Step5: Yes), for performing a notification to move the operation finger 9 while keeping the contact, and outputs broadcast information _{S 3} (Step6). The main monitor 82 acquires the broadcast information S ₃ via the vehicle LAN 80, and displays a message 821 prompting the movement of the operation finger 9 while keeping the contact.

Control unit 3 monitors the capacitance information S ₁ periodically acquired from the biometric information sensor 2 determines whether the operation finger 9 moves. When the operating finger 9 moves (Step 7: Yes), the control unit 3 measures time.

  When “Yes” in Step 8 is established, that is, when the stationary time is equal to or longer than the stationary period 34 (Step 8: Yes), the control unit 3 advances the process to Step 3.

  Here, in step 5, when the control unit 3 can generate the registered biometric information 33 based on the biometric information 26 read so far and the read threshold value 32 (Step 5: No), the control unit 3 generates the registered biometric information 33. (Step 9), and the registration operation is terminated.

  In Step 7, when the operating finger 9 has not moved (Step 7: No), the control unit 3 proceeds to Step 6 and performs notification again.

(Effect of embodiment)
The biological information sensor device 1 according to the present embodiment can reduce an operation load when registering the biological information 26. Specifically, the biological information sensor device 1 continues to read the biological information 26 of the operating finger 9 that moves while the operating finger 9 is in contact with the reading surface 20, that is, without separating the operating finger 9 from the reading surface 20. However, since the registration proceeds, it is possible to reduce the operation load when registering the biometric information 26 as compared with the case of registering the biometric information by repeating contact and non-contact.

  When the biological information sensor device 1 is disposed on the start switch, as an example, the biological information sensor device 1 is often disposed on a panel or the like that faces the user, that is, stands on the floor of the vehicle. In this case, the user extends the hand and operates the start switch, but it is a heavy operation load to repeatedly contact and non-contact during registration. However, since the registration of the biological information sensor device 1 proceeds without removing the operation finger 9 from the reading surface 20, the operation load can be reduced. Therefore, the biological information sensor device 1 can effectively reduce the operation load when it is disposed at a place where the user operates with the hand extended in the horizontal direction.

  In another embodiment, when the biometric information sensor 2 that reads the biometric information 26 to be detected that contacts the reading surface 20 is controlled to register the biometric information 26 and generate the registered biometric information 33 used for authentication, While the contact of the detection target with respect to the reading surface 20 is detected, the reading is performed by a program for executing a registration method for generating the registered biometric information 33 by continuously reading the biometric information 26 of the detection target to be moved, or by a computer recording the program. Provided as a possible recording medium.

These novel embodiments and modifications can be implemented in various other forms, and various omissions, replacements, changes, and the like can be made without departing from the scope of the present invention.
