Description

  The present invention relates to an automatic transaction apparatus capable of guiding the placement of a hand when performing palm vein authentication and finger vein authentication.

Conventional automatic transaction apparatuses include various biometric authentication techniques, such as an authentication technique using palm veins (see, for example, Patent Document 1) and an authentication technique using finger veins (see, for example, Patent Document 2).

However, in the above-described conventional technology, since the biometric authentication method differs depending on the financial institution, there is a problem in that there is a case where there is no compatibility and a transaction with a partner financial institution cannot be performed.
Therefore, by installing both the palm and finger vein authentication units in the apparatus, it is possible to conduct transactions with financial institutions having different authentication methods.

  However, with such an automatic transaction device equipped with both authentication units, the customer may mistake the finger and palm for authentication at the time of transaction. If the position of your finger or palm is not accurate and out of the range that can be authenticated, you will not be able to authenticate and you will be re-authenticated many times, which will take a lot of time and effort for the transaction. Become.

  An object of the present invention is to solve such a problem, and it is possible to authenticate both fingers and palms and to correctly guide the positions on the authentication unit. With the goal.

Therefore, the present invention provides an automatic transaction apparatus equipped with an authentication unit that supports authentication of both finger veins or palm veins by placing the entire palm , and the object to be authenticated is a finger based on information read from the card used. It is characterized in that it is a palm or a palm, and based on the determination result, the correct position where the finger or palm is placed on the authentication unit is switched and guided.

  The present invention thus configured guides the position where the hand is placed by the screen, sound, light emitting element, etc., and the finger or palm outline data or vein pattern data stored in the storage unit and the pattern read by the authentication unit Compared with each other, paying attention to the missing part of the pattern image, the direction of the missing part of the readout pattern can be quickly and surely guided to an identifiable position of the finger or palm. Can be obtained.

  Embodiments according to the present invention will be described below with reference to the drawings.

As shown below, the palm of the customer is guided to the authentication unit as shown in FIG.

S1. The transaction content is selected on the customer operation screen 3 (transaction selection).
S2. Insert a card into the card reader 1 (card insertion).
S3. Information on the inserted card is transmitted to the control unit 6. At this time, the card information includes authentication data for a finger or palm (card information reading).
S4. The control unit 6 reads the finger or palm from the read information of the card. If it is a palm, the process proceeds to S5 and S6, and if it is a finger, the process proceeds to S7 and S8 (confirmation of finger or palm).

S5. The control unit 6 displays a guidance screen and a message for palm vein authentication on the customer operation screen 3, as shown in FIG. 3, and provides voice guidance from the speaker 2 (guide screen for palm vein authentication on the customer operation screen). And display a message and voice guidance.)
S6. As shown in FIG. 5, by blinking or light the localization line 7 flat vein authentication hand shall be the basis of the position of the wrist which is constituted by a light emitting element or the like for guiding the hand of the customer (for palm vein authentication Flash the location confirmation line to guide the customer's hand.)

S7. The control unit 6 displays a finger vein authentication guidance screen and a message on the customer operation screen 3 as shown in FIG. 4, and provides voice guidance from the speaker 2 (a finger vein authentication guidance screen on the customer operation screen). Displays a message and voice guidance.)
S8. As shown in FIG. 5, the finger vein authentication position confirmation line 8 based on the fingertip position is blinked or lit to guide the customer's finger (the finger vein authentication position confirmation line is blinked to indicate the customer's finger). Guide your finger.)

S9. If authentication is OK, the process proceeds to S10 (authentication OK). In the case of authentication NG, the process returns to S4 (authentication NG.). If the authentication NG is repeated a predetermined number of times, the card is ejected and the process ends (repeated a predetermined number of times?).
S10. The transaction process selected in S1 is started (transaction process start).
As described above, by discriminating the finger or palm based on the card information, by displaying the guidance screen and message to the customer's corresponding authentication unit as shown in FIG. 5 on the customer operation screen and performing voice guidance, can correspond to authenticate both plain fingers and hands, it is possible to smoothly deal even different financial institutions biometric authentication method according to the finger and the palm.

In addition, the guidance shown in S5 to S8 is performed before the authentication, but the guidance in S5 to S8 may be performed when the authentication is NG.
Next, in the operation of the above configuration, the operation of the corresponding processing when the finger or the palm is placed on the authentication unit and becomes authentication NG will be described with reference to the flowchart of FIG.

SA1. The transaction content is selected on the customer operation screen 3 (transaction selection).
SA2. Insert a card into the card reader 1 (card insertion).
SA3. Authentication is started, and S3 to S9 of the above operation are performed (authentication start, FIG. 2).
SA4. If the authentication is OK, the process proceeds to SA5 (OK / NG). In the case of authentication NG, the process proceeds to SA6.

SA5. Transaction processing selected by the customer at SA1 is performed (transaction processing).
SA6. The image is read from the finger vein authentication unit 4 or the palm vein authentication unit 5 or both units 4 and 5, and the data is sent to the control unit 6 (image data reading).
SA7. The control unit 6 extracts the outer shape of the finger or palm from the image data transmitted from the finger vein authentication unit 4 and / or the palm vein authentication unit 5, and as shown in FIGS. 7 (A) and 8 (A). Then, it is compared with standard outline data or a finger or palm vein pattern prepared in advance in a storage unit (not shown) in the control unit 6 (comparison with standard data).

SA8. As shown in FIGS. 7B and 8B, if there is a missing image in the right direction, the process proceeds to SA9 (left-right direction data). As shown in FIGS. 7C and 8C, if there is a missing image in the left direction, the process proceeds to SA10. If there is no missing in the left-right direction, the process proceeds to SA11.
SA9. As shown in FIG. 9, the controller 6 displays a screen for guiding the finger or palm to the left on the customer operation screen 3, and provides voice guidance from the speaker 2 (guides the finger or palm to the left). .

SA10. The control unit 6 displays a screen for guiding the finger or palm in the right direction on the customer operation screen 3, and provides voice guidance from the speaker 2 (guides the finger or palm in the right direction).
SA11. As shown in FIGS. 7D and 8D, if there is any missing image in the downward direction, the process proceeds to SA12 (up-down direction data). As shown in FIGS. 7E and 8E, if there is an image loss in the upward direction, the process proceeds to SA13. If there is no omission in the vertical direction, the process proceeds to SA14.

SA12. The control unit 6 displays a screen for guiding the finger or palm upward on the customer operation screen 3, and provides voice guidance from the speaker 2 (guides the finger or palm upward).
SA13. The controller 6 displays a screen for guiding the finger or palm downward on the customer operation screen 3, and provides voice guidance from the speaker 2 (guides the finger or palm downward).
SA14. Since there is no omission in the left and right and top and bottom, it is determined that the person is not authenticated because it is an authentication NG even though there is no problem in the way of placing the hand or finger (mismatch, not the person).

SA15. The card is ejected from the card reader 1 and returned to the customer (card ejection).
As described above, the correction guidance when the finger or palm is shifted left and right or up and down on the authentication unit and cannot be authenticated has been described. However, even when the shift is oblique and tilted as shown in FIG. Similarly to the above, the inclination can be detected based on the standard data and guided to the correct position.

Further, in the case of authentication NG, the guidance shown in SA8 to SA13 is performed. However, guidance in SA8 to SA13 may be performed before the authentication.
In this way, the finger or palm outline data or vein pattern data stored in the storage unit is compared with the pattern read by the authentication unit, paying attention to the missing part of the pattern image, and the missing part of the read pattern. Depending on the direction, it is possible to quickly and surely guide the finger or the palm to the correct position where authentication is possible, thus enabling a quick transaction.
