  The present invention relates to a biological information acquisition apparatus equipped in a device provided with a touch panel, and more particularly, to a biological information acquisition apparatus that acquires biological information using a touch panel of a type that performs position detection using an LED light emitting unit and an LED light receiving unit. Is.

In ATMs (automated transaction devices) installed at financial institutions, etc., when a transaction is made using a cash card (transaction medium), identity verification is performed using a personal identification number. As measures against fraudulent transactions such as counterfeiting of a card or sneak shot of a personal identification number, an IC card is used as a cash card, and an identity verification method using biometric information has been adopted.
IC cards are more difficult to counterfeit than magnetic cards, and biometric information is obtained from a part of the body that has different characteristics, so there is no risk of information leakage due to voyeurism. In ATMs, the use of cash cards with IC cards and identity verification using a combination of personal identification number and biometric information are becoming mainstream.

Various types of biometric information such as fingerprints, vein patterns, irises (iris) have been proposed, but finger vein patterns or palm vein patterns tend to be often used from the viewpoint of ease of information acquisition. .
As a conventional ATM provided with a biological information acquisition device that acquires a finger vein pattern, for example, there is one disclosed in Patent Document 1, and as a conventional ATM provided with a biological information acquisition device that acquires a palm vein pattern, For example, there is one disclosed in Patent Document 2, and in both cases, a biological information acquisition device is installed beside a touch panel equipped on an operation surface of an ATM.

In the figure, reference numeral 1 denotes a touch panel, which is composed of a panel board 1a disposed on a display unit 9 such as an LCD provided on the operation surface of the ATM, and the LED light emitting element 2 and the LED light receiving element 3.

The LED light-emitting elements 2 and the LED light-receiving elements 3 are alternately arranged along the four sides around the panel plate 1a so that the two parallel LED light-emitting elements 2 and LED light-receiving elements 3 face each other. Thus, when the LED light emitting element 2 is caused to emit light, the light is received by the light receiving element 3 facing the LED light emitting element 2.
A general function of the touch panel 1 is a key input function. When a desired key is pressed from the panel board 1a among various keys displayed on the display unit 9, light of the LED light emitting element 2 is pressed at the pressed portion. Therefore, the information defined for the pressed key is input by detecting the position. For example, when a “withdrawal” key is pressed from the panel board 1a on the transaction selection screen, the “withdrawal” is input.

4 is an information acquisition area of width a and length b set on the lower right side of the touch panel 1, and the width a is a width (for example, 30 mm) in which a finger of the maximum width of a Japanese adult can be placed. The length b is a length (for example, 40 mm) at which the portion from the fingertip of the Japanese adult to the first joint can be placed even with the maximum length finger.
Reference numeral 5 denotes a camera as a photographing unit, which is arranged so that the finger 10 placed in the information acquisition area 4 can be photographed from the lower side of the display unit.

FIG. 3 is a block diagram showing a control system of the embodiment.
Reference numeral 6 denotes a control unit, to which each LED light emitting element 2, each LED light receiving element 3, a camera 5, a card connection unit 7, a storage unit 8, a display unit 9, and the like are connected.
The card connection unit 7 is a part for connecting an IC card (transaction medium) of a customer who uses an ATM. The storage unit of the IC card stores the customer's account information (branch number, account number, name, etc.) and the finger of the customer. Vein pattern information is registered.

  The storage unit 8 stores a control program for controlling the operation of the ATM, screen information to be displayed on the display unit, a control program for obtaining a vein pattern of the customer's finger in this embodiment, and the like. Controls the LED light-emitting element 2, the LED light-receiving element 3, and the camera 5 by this control program, acquires the finger pattern of the customer's finger, and exchanges information with the IC card through the card connection unit 7. Yes.

The operation of the above configuration will be described.
When a customer conducts a transaction at an ATM, the customer normally selects a desired transaction from the transaction selection screen displayed on the display unit 9 on the touch panel 1 and then inserts an IC card as a cash card into the card insertion slot. When connected to the connection unit 7, the control unit on the IC card side reads account information from the storage unit and transmits it to the control unit 6 in response to a request from the control unit 6.

Thereafter, the customer inputs a four-digit password using the touch panel 1 in accordance with the password input screen displayed on the display unit 9, and the customer obtains an information acquisition area on the touch panel 1 with the finger 10 in accordance with the guidance displayed on the display unit 9. 4, the control unit 6 acquires the vein pattern information by causing the camera 5 to photograph the finger vein pattern using the LED light emitting element 2 of the touch panel 1 as a light source.
Although the personal identification is performed based on the personal identification number and vein pattern information, the acquisition order of the personal identification number and vein pattern information may be reversed.

The procedure for acquiring the vein pattern information and confirming the identity will be described in more detail.
First, a button with a word meaning “start biometric authentication” is displayed at the center of the display unit 9, and when the customer presses the button with a finger through the panel board 1 a, the control unit 6 is triggered by detection of the pressing. Instructs the camera 5 to prepare for shooting.
The control unit 6 displays a recommended finger placement such as displaying the outline of the finger in the information acquisition area 4 of the display unit 9, and the finger displayed in the information acquisition area 4 in the center of the display unit 9. Displays a message prompting you to place your finger according to how you place it.

When the customer puts the finger 10 in accordance with the message according to this message in accordance with the contour of the finger displayed in the information acquisition area 4, the light from the LED light emitting element 2 passing through the information acquisition area 4 is blocked. It is detected that a finger is placed on the information acquisition area 4 and the camera 5 is caused to take a picture.
At this time, since the finger 10 placed in the information acquisition region 4 is irradiated with light from the LED light emitting element 2 passing through the information acquisition region 4, the finger vein pattern is photographed as an image.

The image captured by the camera is sent to the control unit 6, and the control unit 6 determines whether or not the image is a finger vein pattern image. If the image is a vein pattern image, the control unit 6 converts the image into electronic data. The information is transmitted to the IC card connected to the card connection unit 7 as vein pattern information.
The control unit of the IC card collates the vein pattern information sent from the ATM with the vein pattern information stored in the storage unit, determines whether or not they match, and determines the determination result as the control unit 6 of the ATM. Reply to

When receiving the determination result that the vein pattern information matches from the control unit of the IC card, the control unit 6 displays the determination result on the display unit 9 and switches the information acquisition area 4 to operate as a normal touch panel.
According to the embodiment described above, an information acquisition area is set on the touch panel, a finger is placed on the information acquisition area, and a finger vein pattern is formed by a camera using an LED light emitting element mounted on the touch panel as a light source. Since the biometric information acquisition device can be configured in the touch panel, the operability can be improved, and the area of the operation surface of the ATM can be used effectively.

In addition, the touch panel is placed at the position where the ATM is most easily operated, and the customer only has to place his / her finger on the touch panel, so that the operability is good and the recommended way of placing the finger on the information acquisition area is Since the display is guided and the finger is placed at the displayed position, the operability of the customer can be improved in this respect as well.
In the above-described embodiment, the information acquisition area is set at the lower right of the touch panel. However, the information acquisition area may be set to any part within the range of the touch panel.

In addition, the camera that captures the finger vein pattern may be movable so that it can be captured in an arbitrary area.
In the embodiment described above, the vein pattern information obtained by converting the finger vein pattern image captured by the camera into data is sent to the IC card, and the authentication result of the vein pattern information is received from the IC card. The vein pattern information stored in the unit may be received, and authentication may be performed by comparing the information with the finger vein pattern captured by the camera.
