Description

Biological information acquisition device

The present invention relates to a biological information acquisition apparatus.

User authentication using biometric information that can identify individuals has begun to spread. For example, fingerprints, retinas and irises of eyes, faces, blood vessels, DNA (Deoxyribo Nucleic Acid), and the like are known as biometric information that can be used for authentication.

For example, in financial institutions, customer authentication is performed using a palm vein pattern as biometric information. When performing biometric authentication, information for verification is registered in advance at a financial institution or the like.

At this time, if the posture (shape, orientation, etc.) of the palm is inappropriate, the identity between the information for verification and the information acquired at the time of authentication cannot be confirmed. Therefore, the biometric information acquisition device that acquires biometric information includes a guide that supports a biometric information acquisition site, which is a biometric information acquisition target, in an appropriate posture.

The information input device 1 is a desktop type, and is used by being placed on a counter table at a window of a financial institution, for example. The information input device 1 is required to be downsized in order to improve convenience in such a use environment. In addition, the information input device 1 may be placed on a counter table at the time of use, and may be put away at a predetermined storage position (for example, a locker, a drawer, a shelf, etc.) after use, and may be easily handled. It has been demanded.

The information input device 1 is capable of inputting a personal identification number, inputting a palm vein pattern, inputting information recorded on a magnetic stripe, and inputting information recorded on an IC (Integrated Circuit) card. . The information input device 1 includes a detachable guide 2. The information input device 1 attaches the guide 2 when inputting a palm vein pattern, and removes the guide 2 when not inputting a palm vein pattern.

The information input device 1 has a housing 10 in which a small rectangular parallelepiped box is combined with one side of a large rectangular parallelepiped box. The two large and small rectangular parallelepipeds have the depth direction in the longitudinal direction of the top surface (the surface facing the palm) and the bottom. Further, the two large and small rectangular parallelepipeds are connected with their upper and bottom portions being substantially flush with each other.

The information input device 1 includes a vein sensor 4, an operation unit 11, and an IC reader / writer 12 in the direction of forming a large box of the housing 10. The information input device 1 includes an MS (Magnetic Stripe) reader 9 on a side where a small box of the casing 10 is formed.

The vein sensor (imaging unit) 4 includes an image sensor for imaging the palm (for example, a CMOS (Complementary Metal Oxide Semiconductor) sensor, a CCD (Charge Coupled Device) sensor, etc.), a condensing lens, and a subject that irradiates the subject. And a plurality of light emitting elements (LEDs: Light Emitting Diode) for measuring the distance.

The information input device 1 includes an opening for inserting an IC card into the IC reader / writer 12 on the front surface of the housing 10. The IC reader / writer 12 can read required information from an IC chip included in the IC card, and can write required information. For example, the information input apparatus 1 can record biometric information (registration template) for verification on the IC chip by the IC reader / writer 12. The information input device 1 can read biometric information for verification from the IC chip by the IC reader / writer 12.

The information input device 1 includes an operation unit 11 on the front side of the upper surface of the housing 10 with an opening for inserting an IC card in front. The operation unit 11 arranges a total of 12 operation switches of “0” to “9”, a correction key, and a confirmation key in 4 rows and 3 columns. A display unit 8 is provided on the back side of the operation unit 11. The display unit 8 includes four LEDs, and displays the number of input digits of the password received by the operation unit 11.

The display unit 8 may be a display device such as an LCD (Liquid Crystal Display). When the display unit 8 is an LCD, the operation unit 11 may be a touch panel provided on the LCD.

The information input device 1 includes a wrist guide 5 on the upper surface of the housing 10. The wrist guide 5 is made of a transparent resin and includes the front standing wall 13, the side standing wall 7, and the wrist support portion 14.

The wrist guide 5 includes a front standing wall 13 on the upper surface of the housing 10 on the back side of the operation unit 11 and the display unit 8. The front standing wall 13 is provided between the operation unit 11, the display unit 8, and the vein sensor 4, and partitions the operation unit 11, the display unit 8, and the vein sensor 4. The front standing wall 13 has a required height and functions as a blindfold that prevents the operation unit 11 and the display unit 8 from being observed from the direction of the vein sensor 4.

The front standing wall 13 is painted from the direction of the vein sensor 4 so that the operation unit 11 and the display unit 8 are not visible or difficult to view. Note that the front standing wall 13 is made of a material having a low transmittance, a shape having a large refractive index, or a surface treatment such as application of a shielding seal or uneven processing to reduce the visibility from the direction of the vein sensor 4. Also good.

The wrist guide 5 includes a wrist support portion 14 that supports the wrist of the hand that is crushed by the vein sensor 4 at the upper end of the front standing wall 13. The wrist support unit 14 has a curved surface shape that matches the wrist, and regulates the position and inclination of the wrist to accurately guide the palm to the imaging range of the vein sensor 4. Further, the wrist support portion 14 protrudes from the upper end of the front upright wall 13 in a hook shape in the direction of the operation portion 11. Thereby, the wrist support unit 14 has a function of blinding the operation unit 11 and the display unit 8 from a relatively high viewpoint in the direction of the vein sensor 4. For example, the wrist guide 5 includes the wrist support portion 14 immediately above the display portion 8, so that the display portion 8 can be blinded even when looking into the information input device 1 from above. As a result, even if a staff member who meets at the counter of the financial institution tries to explain the operation of the information input device 1, the customer's input contents and input operations are hidden from the staff member.

As described above, the information input device 1 is configured such that the wrist support portion 14 protrudes from the upper end of the front standing wall 13 in the shape of a hook in the direction of the operation portion 11, thereby suppressing the height of the front standing wall 13 and the operation portion 11 and The function of hiding the display unit 8 is improved.

The wrist guide 5 includes side standing walls 7 on both sides of the front standing wall 13. The side upright wall 7 is made of a transparent resin like the front upright wall 13, and the operation unit 11 and the display unit 8 are painted from the left and right directions of the information input device 1 so that they cannot be seen or are difficult to see. Therefore, the front upright wall 13 and the side upright wall 7 serve as a hood-like blindfold with the front (front side) and the upper side of the information input device 1 opened, and a third party peeks at the password input operation and input contents. To prevent that.

Further, the rigidity of the front upright wall 13 and the side upright wall 7 is improved by integral molding. The side upright wall 7 integrally formed with the front upright wall 13 prevents the front upright wall 13 rising from the upper surface of the housing 10 from being tilted in the direction of the operation unit 11. Thereby, the information input device 1 improves the sense of stability of wrist support by the wrist support portion 14.

The information input device 1 includes a finger guide 16 on the upper surface of the housing 10 and on the back side of the wrist support portion 14. The finger guide 16 is rectangular and plate-shaped. The finger guide 16 stands up vertically from the upper surface of the housing 10, and then bends and bends in a direction to escape from the imaging range of the vein sensor 4, and further bends in the vertical direction near the upper end. The finger guide 16 supports the finger at the upper end portion of the standing wall. The finger guide 16 is provided apart from the wrist support 14 by a standard palm length (for example, 110 mm).

The information input device 1 includes a vein sensor 4 on the upper surface of the housing 10 and on the back side of the wrist support portion 14. The vein sensor 4 faces upward from a rectangular opening on the upper surface of the housing 10. The vein sensor 4 is provided between the wrist guide 5 and a finger guide 16 on the back side of the vein sensor 4 on the upper surface of the housing 10. The vein sensor 4 sets the upper surface of the housing 10 in the sensing (imaging) direction and captures a vein image of the palm supported by the wrist guide 5 and the finger guide 16.

The information input device 1 can support the palm by the wrist guide 5 and the finger guide 16, but it is recommended that the guide 2 be attached in order to support the palm in a more appropriate posture when capturing a vein image of the palm. .

The information input device 1 is connected to the power cable 6a and the signal cable 6b connected to the computer on the back side of the housing 10. The power cable 6a connects the computer and the information input device 1 so that power can be supplied from the computer to the information input device 1. The signal cable 6b connects the computer and the information input device 1 so that they can communicate with each other. The power cable 6a and the signal cable 6b can be, for example, USB (Universal Serial Bus) cables.

The information input device 1 includes an MS reader 9 on the side where a small box of the casing 10 is formed. The MS reader 9 opens the slit upward, and reads information from the MS card inserted from the back side of the slit and slid to the front side. The slit has a length from the side of the vein sensor 4 to the side of the operation unit 11 and penetrates a small box of the casing 10 in the longitudinal direction. The information input device 1 makes the guide 2 detachable and facilitates the MS card slide operation with the guide 2 removed. Thereby, the information input device 1 can avoid the interference between the operator of the MS card slide operation and the guide 2, and allows the housing 10 to be downsized while having the MS reader 9.

The guide 2 has a shape capable of guiding the hand to an appropriate posture so that the vein sensor 4 can stably acquire a vein image of the palm. The guide 2 has a box shape (inverted quadrangular pyramid) that expands upward with the bottom 21 as a rectangle, and has a concave chamber 22 that opens upward. The concave chamber 22 is formed by a front wall 19 erected from four sides of the bottom portion 21, a rear wall 25, two side walls 26, and the bottom portion 21.

The bottom portion 21 includes a window portion 15 in the center portion and a slit 27 along the front wall 19. The window portion 15 is located at a position corresponding to the vein sensor 4 when the guide 2 is mounted, and has a size that encloses the vein sensor 4 in a rectangular opening area.

The slit 27 is located at a position corresponding to the finger guide 16 when the guide 2 is mounted, and has a size and a shape through which the finger guide 16 can be inserted. The slit 27 has a rectangular shape, the longitudinal direction is in contact with the lower end of the front wall 19, and the bottom portion 21 is notched to the full width in the left-right direction. The guide 2 is guided so as to be properly mounted on the upper surface of the housing 10 (the pedestal surface of the guide 2) by inserting the finger guide 16 through the slit 27.

The guide 2 includes a hook-shaped finger support portion on three sides of the four sides on the open end side. The finger support unit includes a three-finger support unit 17 and first and fifth finger support units 3 on both sides of the three-finger support unit 17. The three-finger support portion 17 is located on the side facing the wrist guide 5 with the vein sensor 4 interposed therebetween, and supports the three fingers from the second finger to the fourth finger. The first finger / fifth finger support unit 3 supports either the first finger or the fifth finger. The three-finger support portion 17 is located at the upper end of the front wall 19 that stands up from the bottom portion 21. The first finger / fifth finger support portion 3 is located at the upper end of the side wall 26 rising from the bottom portion 21.

The three-finger support part 17 and the first / fifth finger support part 3 are connected via a step 20 having a predetermined height (for example, 5 mm). The first finger / fifth finger support 3 is connected to the upper end of the rear wall 25 via a step 24 having a predetermined height (for example, 5 mm).

The guide 2 includes two hemispherical protrusions 28 on the back side of the bottom 21. The two protrusions 28 are respectively fitted with the two positioning guides 18 on the upper surface of the housing 10 to guide the guide 2 to the normal position. Thereby, the movement of the guide 2 in the front-rear direction with respect to the housing 10 is restricted. Further, the fitting between the projection 28 and the positioning guide 18 can give a person in charge of mounting the guide 2 to the housing 10 a feeling of mounting in the normal position. Note that the information input device 1 provided with two pairs of the projections 28 and the positioning guides 18 is illustrated, but the projections 28 and the positioning guides 18 may be one pair each, or Three or more pairs of the positioning guides 18 may be used.

Further, the guide 2 is provided with a convex fitting portion (protrusion 28) on the back surface side of the bottom portion 21 and a concave fitting portion (positioning guide 18) on the upper surface of the housing 10, but the back surface side of the bottom portion 21 is provided. May be provided with a concave fitting portion, and a convex fitting portion may be provided on the upper surface of the housing 10.

The guide 2 includes a pair of side guides 23 on the left and right sides so as to protrude from the bottom 21 at the lower end on the back side of the side surface. The side guide 23 is a substantially trapezoidal tongue-like standing wall, and extends from the side of the slit 27 toward the window 15. When the guide 2 is mounted on the housing 10, the side guide 23 abuts on the side surface of the housing 10 and guides the mounting of the guide 2 to the normal position. Thereby, the guide 2 is restricted from moving in the left-right direction with respect to the housing 10. Further, the side guide 23 can inform the person in charge of mounting the guide 2 on the housing 10 of the presence of the foreign material if there is a foreign material directly under the side guide 23 when the housing 10 and the guide 2 are mounted. it can.

As described above, the information input device 1 attaches the guide 2 to the housing 10, so that the palm is placed in the normal position by the wrist support unit 14, the three-finger support unit 17, and the first / fifth finger support unit 3. Can be supported. In addition, the information input device 1 can suitably acquire a vein image of the palm by limiting the intrusion of disturbance light into the concave chamber 22 by forming the guide 2 with an impermeable resin.

Further, the guide 2 has a shape surrounding the palm and the vein sensor 4, so that the heat generated from the heat generating part (for example, a power supply part or an electronic component) in the housing 10 warms the palm. Can keep warm. At this time, the contact between the upper surface of the housing 10 and the bottom portion 21 contributes to heating in the concave chamber 22 due to heat radiation from the upper surface of the housing 10. Further, the opening of the window portion 15 contributes to heating in the concave chamber 22 due to heat radiation from the vein sensor 4.

Note that the information input device 1 does not require the guide 2 to be attached to the housing 10, and can support the palm with the wrist support portion 14 and the finger guide 16. For example, in an environment with little disturbance light, the information input apparatus 1 can easily obtain a vein image of the palm by omitting the mounting of the guide 2 on the housing 10.

However, a template registered in a state where the posture of the palm is not appropriate may reduce the accuracy of identity verification at the time of collation. Therefore, in order to perform template registration with an appropriate palm posture, it is recommended that the information input apparatus 1 be mounted with the guide 2 on the housing 10.

Since the information input device 1 has the guide 2 detachable, the information input device 1 can be used during operation without imaging of the veins of the palm (for example, input of a password, read / write of an IC card, read of an MS card). The input device 1 can be handled in a compact size. As a result, the information input device 1 can be easily operated at a window of a financial institution that requires downsizing of the device.

Next, a state where the guide 2 according to the embodiment is mounted on the housing 10 and a state where the palm is placed on the information input device 1 will be described with reference to FIGS. FIG. 5 is a diagram illustrating a side surface of the information input device according to the embodiment. FIG. 6 is a bird's-eye view showing a state when a palm vein is imaged in the information input device of the embodiment. FIG. 7 is a side view illustrating a state when a palm vein is imaged in the information input device according to the embodiment. In the information input device 1 illustrated in FIG. 5, the guide 2 is represented by a broken line in order to facilitate understanding of the attachment and detachment of the guide 2.

The wrist guide 5 includes a front standing wall 13 that is bent into a “<” shape when observed from the side, and a wrist support portion 14 at the upper end of the front standing wall 13. The front standing wall 13 rises from the upper surface of the housing 10 with an inclination of an angle r2 (for example, 10 °), and bends so as to have an angle r1 (for example, 10 °) at the intermediate portion. The angle r <b> 2 moves the front upright wall 13 backward from the imaging range (within the angle of view) of the vein sensor 4. As a result, the information input device 1 can increase the imaging range of the palm, the arrangement area of the display unit 8 and the operation unit 11, and the operation space of the operation unit 11.

The finger guide 16 stands vertically from the upper surface of the housing 10 by a predetermined height (for example, the thickness of the bottom portion 21 of the guide 2), and then has an angle r4 (for example, 10 °) in a direction to escape from the imaging range of the vein sensor 4. Just bend and bend. The finger guide 16 is further bent in the vertical direction in the vicinity of the upper end. The angle r4 moves the finger guide 16 backward from the imaging range (within the angle of view) A of the vein sensor 4. Thereby, the information input device 1 can aim at expansion of the imaging range of the palm.

The finger guide 16 has a function of guiding the correct mounting position when the guide 2 is mounted on the housing 10. The guide 2 is guided to the correct mounting position by inserting the finger guide 16 through the slit 27. The guide 2 can be guided by the inclination of the finger guide 16 so as to avoid interference with the wrist guide 5 (particularly, the wrist support portion 14), and the design of the position and shape of the wrist support portion 14 is free. Contributes to improving the degree.

The guide 2 in which the finger guide 16 is inserted into the slit 27 is fitted in the correct position by fitting the positioning guide 18 and the projection 28 on the upper surface of the housing 10. The fitting between the positioning guide 18 and the protrusion 28 guides the guide 2 to the normal position in the front-rear direction against play in the front-rear direction of the finger guide 16 inserted through the slit 27. Further, the contact between the housing 10 and the side guide 23 guides the guide 2 to the normal position in the left-right direction with respect to the play in the left-right direction of the finger guide 16 inserted through the slit 27. Thereby, the information input device 1 can mount the guide 2 at the correct mounting position of the housing 10.

When the guide 2 is correctly mounted, the first finger / fifth finger support portion 3 and the three finger support portion 17 are horizontal, and the palm supported by the guide 2 and the vein sensor 4 face each other. The mounted guide 2 rises with the rear wall 25 having an inclination of an angle r3 (for example, 10 °) from the upper surface of the housing 10. The angle r <b> 3 moves the rear wall 25 backward from the imaging range A of the vein sensor 4. The guide 2 is provided with a predetermined inclination on the front wall 19 and the side wall 26 in the same manner as the rear wall 25. Thereby, the information input device 1 can increase the imaging range of the palm when the guide 2 is mounted.

When the guide 2 is correctly mounted, the three-finger support portion 17 is positioned lower than the wrist support portion 14 by a predetermined height d1 (for example, 5 mm). The upper end of the finger guide 16 and the three-finger support portion 17 are located at substantially the same height. The first finger / fifth finger support unit 3 is connected to the three-finger support unit 17 through the step 20, and is positioned at a position lower than the three-finger support unit 17 by a predetermined height d2 (for example, 5 mm).

As described above, the information input device 1 is suitable for the palm vein by the vein sensor 4 by supporting the wrist, the second finger to the fourth finger, and the first finger and the fifth finger with a predetermined step. Sensing can be performed.

Note that the guide 2 has the upper end of the rear wall 25 lower than the side wall 26 by the level difference 24. Thereby, the information input device 1 can set the imaging range A of the vein sensor 4 up to the wrist or the vicinity of the wrist.

The information input device 1 includes the five-finger crotch portion in the imaging range A, thereby facilitating hand posture determination and palm range specification. Moreover, the information input device 1 includes the wrist or the vicinity of the wrist in the imaging range A, thereby facilitating the hand posture determination and the palm range specification.

Next, the mounting state of the guide of the information input device of the embodiment will be described with reference to FIG. FIG. 8 is a diagram illustrating a mounting state of the guide of the information input device according to the embodiment.
First, the information input device 1 in a state where the guide 2 is correctly mounted (FIG. 8A) will be described. The guide 2 is normally attached to the housing 10 by inserting the finger guide 16 into the slit 27, fitting the positioning guide 18 and the protrusion 28, and contacting the housing 10 and the side guide 23. The guide 2 normally mounted on the housing 10 makes the upper end of the finger guide 16 and the three-finger support portion 17 substantially flush. That is, both the upper end of the finger guide 16 and the three-finger support portion 17 have the same height and are both horizontal.

Therefore, the person in charge who mounts the guide 2 on the housing 10 can accurately grasp the normal mounting by viewing the upper end of the finger guide 16 and the three-finger support portion 17. Such visual confirmation of the mounting state can be made easier by forming the finger guide 16 with a transparent resin and allowing the three-finger support portion 17 to be observed through the finger guide 16. Further, since the upper end of the finger guide 16 and the three-finger support unit 17 are arranged close to each other, the user (biological information acquisition target) can place the finger guide 16 when the three fingers are placed on the three-finger support unit 17. It is also possible to confirm the wearing state of the guide 2 by touching the touch.

Next, the information input device 1 in a state where the guide 2 is mounted with a foreign object in between (FIG. 8B) will be described. For example, when the foreign object 30 such as a pencil or a cable is on the upper surface of the housing 10 and the guide 2 is to be mounted, if the foreign object 30 is between the slit 27 and the vein sensor 4, the side guide 23 is the foreign object 30. Interfere with. At this time, if only one of the side guides 23 on both sides interferes with the foreign material 30, the guide 2 is greatly inclined in the left-right direction. This state can be easily confirmed by the fact that the upper end of the finger guide 16 and the three-finger support portion 17 have different inclinations and are not substantially flush with each other. Further, if both the side guides 23 on both sides interfere with the foreign material 30, the guide 2 is largely inclined in the front-rear direction. This state can be easily confirmed by the difference in height between the upper end of the finger guide 16 and the three-finger support portion 17 and not being substantially flush.

Next, the information input device 1 in a state where the guide 2 is mounted with a foreign object in between (FIG. 8C) will be described. For example, when the guide 2 is to be mounted in a state where a foreign object 31 such as a coin, a clip, or a slip is on the upper surface of the housing 10, the guide 2 is inclined in the left-right direction or the front-rear direction, or the left-right direction and the front-rear direction. This state can also be easily confirmed by the fact that the upper end of the finger guide 16 and the three-finger support portion 17 have different inclinations and are not substantially flush with each other.

Next, the configuration of the information input apparatus according to the embodiment will be described with reference to FIG. FIG. 9 is a diagram illustrating a configuration of the information input device according to the embodiment.
The information input device 1 includes a control unit 70, a communication unit 71, a storage unit 72, an image processing unit 73, an encryption processing unit 74, and an input / output interface unit 75. The control unit 70 comprehensively controls each processing unit. The storage unit 72 temporarily stores necessary information. The image processing unit 73 performs image processing on the image information. The encryption processing unit 74 encrypts necessary information.

The input / output interface unit 75 connects the vein sensor 4, the operation unit 11, the display unit 8, the IC reader / writer 12, the MS reader 9, and the SAM (Security Access Module) unit 79. The communication unit 71 is connected to a computer to transmit / receive data. The SAM unit 79 ensures the security of the information input device 1. For example, the SAM unit 79 stores identification information that can uniquely identify the information input device 1 to guarantee the validity of the information input device 1 or stores an encryption key or a decryption key so that the information input device 1 Encrypt or decrypt information to be input / output.

With such a configuration, the information input device 1 inputs a palm vein image, an operation input by a user, an input of required information recorded on an IC card, and an input of required information recorded on an MS card. be able to.

Next, an authentication system in which the information input device of the embodiment is used will be described with reference to FIG. FIG. 10 is a diagram illustrating a registration device including the information input device according to the embodiment and an authentication system including the registration device.

The authentication system 50 is one of information processing systems that recognizes the characteristics of a living body and identifies and authenticates an individual. For example, a customer is authenticated by a bank system or the like. The authentication system 50 includes an information processing device such as a registration device 60, a plurality of automatic depositing devices 53, and an authentication server 51, and a network 55.

The authentication server 51 associates and stores identification information for identifying an individual and verification information (template) registered in advance before biometric authentication. The identification information for identifying an individual is a unique ID (IDentification) assigned to a user directly (for example, a user number) or indirectly (for example, an account number).

One or a plurality of automatic depositing devices 53 are installed in an ATM (Automated Teller Machine) corner 52 or an ATM booth 54 in a financial institution. The automatic depositing device 53 is one of authentication devices that perform biometric authentication when authenticating a user prior to a financial transaction. The automatic depositing device 53 includes an IC reader / writer 56 and a sensor unit 57.

The sensor unit 57 includes an imaging device and captures a vein image of the palm of the user. The automatic teller machine 53 includes collation information specified from identification information read from a user's IC card (for example, an IC chip built-in cash card) by the IC reader / writer 56 and veins of the user's palm acquired from the sensor unit 57. The user is authenticated from the image.

The registration device 60 is a device that is provided at a bank counter or the like and performs user template registration according to instructions or operations of a staff member. The registration device 60 includes a processing device 61, a display 62, and the information input device 1, and includes a keyboard 63, a mouse 64, and the like as necessary. The information input device 1 incorporates an imaging device and captures a vein image of the palm of the user. The information input device 1 outputs collation information generated based on the imaged vein image of the palm or the vein image of the palm. The information input device 1 records the palm vein image or the collation information in at least one of the storage unit of the processing device 61, the storage unit of the authentication server 51, or the storage unit of the user's IC card 65.

The authentication system 50 shown in FIG. 10 connects the information input device 1 to the processing device 61 to configure the registration device 60. However, if the verification information is already registered as a template, the authentication system 50 is an authentication device that performs biometric authentication. You can also For example, the automatic depositing device 53 can replace the sensor unit 57 with the information input device 1.

In the embodiment, the vein image of the palm is exemplified as the biometric information used for authentication. However, the information input device 1 can also use the biometric information used for authentication as a palm print.
