Abstract

PURPOSE:To identify the real user of an ID card by comparing net rentia pattern information stored on the ID card with a rentia pattern obtained from the user of this ID card and deciding whether or not the pupil of the ID card user reacts. CONSTITUTION:Rentia patterns obtained before a light emitting device 30 illuminate, namely, the rentia pattern information written on the ID card and the rentia pattern used when the rentia pattern of the card user is compared to decide the reaction of the pupil from their difference. The decision information on the pupil reaction is sent to a main control part 21. The digital values of the rentia pattern stored on the memory in the main control part 21 and the rentia pattern information obtained from the ID card 6 are compared, bit by bit, to check whether or not the rentia pattern matches with the rentia pattern information. Further, it is judged from the decision information obtained from a pupil reaction decision part 34 whether or not the rentia pattern is a pattern obtained from a living body. Consequently, it can be confirmed whether or not the ID card 6 corresponds to its user.

Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Field of Industrial Application) This invention relates to a personal identification device capable of identifying a true ID card holder.

(Prior Art) Conventionally, cards provided with a magnetic stripe have been used as ID cards used in financial institutions, such as banks.

As a means to further confirm the identity of the card and its holder, the ID card holder can be identified by matching the several-digit PIN recorded on the magnetic stripe with the PIN entered by the holder. A method of identification is used.

However, since the recorded contents of magnetic stripes can be read and written by devices other than banks,
There were problems such as the possibility that the PIN number would be known to someone other than the ID card owner, and incidents of ID card theft due to repeated unauthorized PIN numbers.

In order to solve this problem, a method using retinal pattern information as personal identification information stored in an ID card has been proposed in Japanese Patent Laid-Open No. 60-72067. In this method, a means for reading the retinal pattern of an ID card user is prepared, and by comparing the retinal pattern read by the reading means and the retinal pattern information stored in the ID card, the ID card and its owner are identified. This is to confirm the following.

This method has made card theft more difficult, but for example, if someone copies the ID card holder's retinal pattern onto a film, etc., and uses the ID card, this film can be transferred to the reading means. By having it read,
Since the device recognizes the ID card as if it were the real owner of the ID card, it is possible for the ID card to be stolen.

(Problems to be Solved by the Invention) As described above, it is not possible to simply compare the retinal pattern information read from the reader with the retinal pattern read from the individual. There was a problem in that the ID card could be stolen by someone who was not the true owner of the ID card, such as by putting it on a film, etc., and having the film read by someone who was not the true owner of the ID card and pretending to be the true owner of the ID card. . This invention was made in view of this point, and is a personal identification device that can identify the true ID card owner by determining the card user's pupillary reaction and identifying the retinal pattern. The purpose is to provide

[Structure of the invention]

(Means for Solving the Problems) In order to achieve the above object, the present invention provides an ID card in which identification information of a certain individual and information on a retinal pattern obtained from the eyes of this individual are stored. . It also includes a reading unit that reads information stored in the ID card, an input unit that inputs a human retinal pattern, and a retinal pattern information read by the reading unit and the retinal pattern read from the input unit. It is provided with a comparison section for comparison and a discrimination section for discriminating the pupillary reaction of the ID card user. This ID is determined by the information from this comparison section and discrimination section.
It is characterized by identifying the individual who owns the card.

(Operation) The retinal pattern information stored in the ID card and the retinal pattern input by the input unit are compared in the comparison unit, and if they match, it is possible to identify the owner of the ID card. Furthermore, by determining whether there is a pupillary reaction in the determining section, it is possible to identify whether the retinal pattern was obtained from a living body.

(Example) Hereinafter, one embodiment of the present invention will be described with reference to the drawings.

FIGS. 1 and 2 show an external view and internal blocks of a bank's automated teller machine as an example of an embodiment of the present invention. On the front of the housing 1, there is an abbreviated operation section 2.

A banknote outlet 3 from which disbursed banknotes are taken out is provided on the horizontal surface of the operating section 2, and a door 4 that can be opened and closed is provided in the banknote outlet 3. Further, on the horizontal surface of the operation section 2, a color CRT display section 5 with a built-in touch sensor, for example, is provided. This CRT display section 5 displays operating procedures and other information on the CRT screen in the form of illustrations, characters, or words to guide the user, and also displays information such as passwords, amounts, account numbers, approval, confirmation, or cancellation of transactions. By pressing the display part according to the
This is a so-called key operation that outputs a corresponding signal to the main control section 21, which will be described later. Further, a card insertion lower for inserting an ID card 6 is provided on the vertical surface of the operation unit 2, and a card insertion lower for inserting an ID card 6 is provided.
An electronic camera 8 into which the owner's retinal pattern and pupillary reaction are input, and a key switch 10 for an attendant are provided.

By the way, inside the housing 1, there is a main control section 21 that controls the entire system.
, the ID shown in FIG. 3 inserted from the card insertion lower
The card 6 is accepted, data such as retinal pattern information from the main control section 21 is recorded in the laser recording section 11 on the ID card 6, and the data in the laser recording section 11 is read and output to the main control section 21. ID card read/write section 12
, a journal printing unit 13 that prints on a journal, a dispensing unit 15 that dispenses banknotes of a specified amount to the banknote output port 3, a customer service unit 15 comprised of a CRT display unit 5, and a speaker (not shown), etc. A voice guidance unit 19 for providing voice guidance to customers, an internal monitor 20 for the staff, a floppy disk 23 in which all transaction data is stored, a power supply section 22, and an image input section 17 are provided. This image input unit 17 is for inputting the customer's retinal pattern and pupillary reaction. For example, as shown in FIG. It converts an analog signal, which is a video signal from the electronic camera 8, into a digital signal, which is image information. When the changeover switch 9 is switched to the retinal pattern information compression section 33 side, the retinal pattern information compression section 33 digitally compresses the image information from the A/D 31 and stores it in the memory within the main control section 21 .

The pupillary reaction determining section 34 switches the switch 9 to the pupillary reaction determining section 3.
4 side, the light emitting device 30 emits light, and image information is obtained from the A/D 31 as described above.

This image information is then digitally compressed by the retinal pattern information compression section 35 in the pupillary reaction determination section 34 shown in FIG. Next, the information previously stored in the memory in the main control section 21 is read out, and the comparison section 32 compares the digitally compressed digital values of each bit degree.

The presence or absence of a pupillary reaction is determined based on the presence or absence of a change in this digital value.

Note that the main control unit 21 is connected to a remote monitor 24 for use by staff members.

As shown in FIG. 3, the ID card 6 is provided with a laser recording section 11 on its surface for storing retinal pattern information and a password. The laser recording section 11 is coated with a metal film layer such as tellurium or bismuth.

The personal identification method of the present invention will be explained using the configuration described above. First, the issuance of an ID card will be explained. An attendant inserts a key into the key switch 9 shown in FIG.

Next, the clerk uses the CRT display section 5 to instruct the issuance of an ID card and inputs the account number and the like. Then, the main control unit 21 shown in FIG. However, the KID card is transported. The main control section 21 uses the CRT display section 5 to provide guidance such as "Please look into the camera." Thereby, the customer is supplied to the main control section 21 in the manner described above through the electronic camera 8, except for the electronic camera 8 shown in FIG. The main control section 21 causes the ID card read/write section 12 to output the retinal pattern information. Then, the ID card read/write section 12 causes the laser recording section 11 of the ID card to record this retinal pattern information.

The ID card 6 on which this retinal pattern information has been recorded is ejected from the card insertion slot by controlling the driver 15 in FIG. 2 to rotate the ejection port 214. The ID card 6 is issued according to the above principle.

Next, as explained above, a withdrawal transaction using the issued ID card 6 will be explained below. An ID card user (hereinafter referred to as user) inserts the ID card 6 into the card insertion lower shown in FIG. The ID card 6 is taken into the ID card read/write section 12 by rotating the take-out roller 14 by the driver 15 shown in FIG. The ID card read/write section 12 reads the laser recording section 11 of the ID card 6, and the read information is stored in the internal memory within the main control section 21.

The main control section 21 uses the CRT display section 5 shown in FIG. 1 to provide guidance to the user, for example, "Please look into the camera." When the user looks into the camera, the signal processing described above is performed in the image input section 17 of FIG. 2. Then, the user's retinal pattern is obtained. Next, at the same time that the main control section 21 obtains the retinal pattern, light is emitted from the light emitting device 30 according to a command from the main control section 21.

The intensity of this light emission is adjusted to a level that is not harmful to the human eye, and yet allows a pupillary reaction to be obtained. As has been explained so far, the retinal pattern obtained when the light emitting device 30 emits light, the retinal pattern information written on the ID card and the ID card user's information before the light emitting device 30 emits light. Retinal pattern and light emitting device 30 used when comparing retinal patterns
Comparing the retinal pattern obtained when emitting light with
Pupillary reactions are determined based on the presence or absence of changes. This pupil reaction discrimination information is transmitted to the main control unit 21. Main control unit 21
The digital values of each bit degree are compared to see if the retinal pattern stored in the memory in the card 6 matches the retinal pattern information obtained from the card 6. Further, based on the discrimination information obtained from the pupillary reaction discrimination section 34, it is determined whether the retinal pattern is obtained from a living body. Therefore, it is possible to confirm the correspondence between the card 6 and its owner.

Therefore, as explained above, when the retinal pattern information matches and the pupillary reaction is determined, an instruction is given to input the transaction type and amount, and the corresponding input is performed as shown in Figure 1.
When the RT display section 5 performs the transaction, the main control section 21 causes the withdrawal unit 16 to perform a withdrawal process according to this transaction data.

In addition, if the retinal pattern information does not match, or
If no pupillary reaction is detected, the main control unit 21
For example, using the CRT display unit 5 shown in Figure 1, you can see a message saying ``Unrecognized.Please look into the camera again.''

” and perform the operations described above again.

Although the ID card used in the above explanation is plate-shaped, it is not limited to this and may be of a bar-like shape. Further, the means for identifying the retinal pattern and detecting the pupillary reaction described above are merely examples, and all means that do not impair the effects of the present invention are included in the present invention.

〔Effect of the invention〕

As described in detail above, according to the present invention, the retinal pattern information stored in the ID card is compared with the retinal pattern obtained from the ID card user, and the retinal pattern information of the ID card user is compared. By determining the presence or absence of a pupillary reaction, the true owner of the card can be better identified. Therefore, card theft is further prevented.
