JPS6293752A - Card truth discriminating device - Google Patents

Abstract

PURPOSE:To discriminate correctly the truth even if a data in a card is copied, by storing in advance the truth discriminating information in the card by using a fluorescent paint, and reading this information. CONSTITUTION:Magnetic information of a magnetic stripe 11 of a card 10 is read through the magnetic head 21a of a read part 21, the read information is stored in a RAM26, and from the stored information, an ID number is segmented. The ID number of a fluorescent paint recording part 12 of the card 10 is read through the CCD image sensor 21c of the read part 21, and it is stored in the RAM26. The ID number read from the magnetic stripe 11, and the ID number read from the fluorescent paint recording part 12 are compared, and when they coincides, with each other transmission and reception are executed to and from a host computer in accordance with transaction information. When they do not coincide, the card 10 is returned or collected through a carrying mechanism 22 and processed as an undesignated card.

Description

[Detailed description of the invention] Industrial application fields> The invention relates to a card authenticity determination device.

<Summary of the Invention> According to the present invention, information for determining authenticity is recorded in advance on the surface of a card using a fully fluorescent paint, and the authenticity of the card is determined by reading this information.

<Prior art> Generally, transaction processing cards such as magnetic cards used in bank automatic teller machines, IC cards (cards with built-in integrated circuits), and racer cards contain a code such as a recited number in addition to a transaction processing code. ID information is stored.

Conventionally, the card Kl+% discrimination@# in such an automatic payment machine etc. has compared the ID information read from the card with the ID information entered from a numeric keypad or the like to determine the authenticity of the card.

<Problems to be solved by the invention> However, with such a card authenticity determination method, especially if the IC card interface is standardized, an abuser may be able to steal the transaction processing code or ID of himself or the target. There is a risk of reading the information and duplicating the card. in this case,
The discrimination device has a problem in that it discriminates a duplicated card as "authentic" if correct ID information is input at the time of transaction.

SUMMARY OF THE INVENTION In view of the above-mentioned problems of the prior art, it is an object of the present invention to provide a device that can determine the authenticity of a transaction card showing $1.

Means for Solving the Problems> In order to solve the above problems, the present invention stores information for determining authenticity on a card using fluorescent paint in advance, and reads this information to determine authenticity. It is characterized by having 11 additional features.

Effect> The non-invention is due to the above structure, transaction processing information in the card and I
Even if the D information or the like is copied, it is possible to accurately determine authenticity as long as the ID information is not stored in the area coated with fluorescent paint.

Embodiments Hereinafter, the present invention will be described in detail with reference to the drawings. FIG. 1 is a plan view showing one row of magnetic cards 10 according to the invention, in which a magnetic stripe 11 in which transaction processing information and an ID number are stored as magnetic information, and a magnetic stripe 11 on which transaction processing information and an ID number are stored, and the ID number is ：J has a fluorescent paint recording section 12 recorded in numbers. In this example, a fluorescent paint that emits infrared light is used.

The second prisoner is a block diagram showing an embodiment of a card transaction processing device (terminal device) such as an automatic payment machine having a card authenticity determination device according to the present invention, and FIG. 3 is a reading unit 2 of the device shown in FIG.
1 is a schematic configuration diagram of FIG.

The one-shot section 21 in FIG. 3 includes a magnetic head 21a for capturing the magnetic information 4:h t iJt in the magnetic stripe 11 of the card 10 shown in FIG. It is composed of an infrared light emitting diode array 21b and a CCD image sensor 21C for reading the numbers on the fluorescent paint recording section 12. In addition, the fluorescent paint recording section 12
To the numbers! 5. For accurate reading, the sensor 21C may be provided with an interference filter.

Returning to FIG. 2, this card authenticity determination device includes the above-mentioned reading section 21, and 6 mechanisms 2 for detecting the card 10 and feeding the card 10 by Δ.
2, a key manual unit 23 into which transaction information is input, a central processing unit (CPtJ) 24, and a CPU as shown in FIG.
It is composed of a read-only memory (ROf~1) 25 in which 24 execution programs are stored, and a random access memory (l(, AM) 26 having a work area of CP (J24), etc.).

Note that the CPU 24 is connected to the host computer via a network control section 27 or the like.

The operation of the embodiment according to the above configuration will be explained with reference to Figure 4 and above. First, in step (hereinafter referred to as ST) 1, when the card 10 is inserted, ST2 to ST4 and ST5 are inserted.
~ Proceed to ST6 and perform parallel processing.

In ST2 and below, the magnetic information on the magnetic stripe 11 of the card 10 is read through the magnetic head 21a of the reading section 21, and then the information sound RAM 26 read in 8T3 is read.
to be memorized. Continuation (In ST4, an ID number is extracted from the stored information.

On the other hand, in ST5, the CCD image sensor 2 of the reading section 21
ID of the fluorescent paint recording section 12 of the card 10 via 1C'
Read the number and store it in Et, AM26 (8T
6).

In the 8T7, the ID number read from the magnetic stripe 11 (
s'r2 to ST4) and the ID number (8T5 to ST6) read from the fluorescent paint recording section 12, and if they match, the process proceeds from ST8 to 8T9.

In ST9, the card 10 is processed as a normal card, and data is exchanged with the host computer according to the transaction processing information on the magnetic stripe 11 and the transaction information inputted in the key input section 23.

On the other hand, if the two ID numbers do not match in ST8, the process branches to 5TIO, and the card 0 is returned or collected via the transportation system 22 and treated as a non-designated card.

Note that the card 10J) has a numerical ID on the fluorescent paint recording section 12.
Although numbers are recorded, symbols or /ku-codes may also be recorded. In the case of barcodes, you can use a 7-inch sensor instead of a 2-IC CCD image sensor.

Moreover, instead of the recording method described above, the information may be encoded (scrambled) and recorded on the a-like stripe 11, and the entire decoded information may be stored in the fluorescent paint recording section 12. FIG. 5 shows a flowchart in this case.

First, when a card is inserted in s'rii, 5T1
Proceed to steps 2 to 5T13 and 5T14 to S'r15 to perform parallel processing.

For 8T12 and below, information on the magnetic stripe is retrieved and stored, and for 5T14 and below, all information is read and recorded from the fluorescent paint recording section. Next, in 5T16, the information retrieved from the magnetic stripe is decoded using the information obtained from the fluorescent paint recording section, and d (0 code is determined in 8T17 to determine whether the code rules match and the decoding is successful. If the rules match, s 'r I
Proceed to B and process the card as a normal card based on the decrypted information.On the other hand, if the code rules do not match, the card will be processed as 5T19.
The card is branched to and treated as an unspecified card.

It goes without saying that the present invention is not limited to magnetic cards, but can also be applied to laser cards and IC cards. In the case of an IC card, it may be configured such that the information in its own light-paint recording section is read by the card transaction sinking device, and the card side receives this information and performs all authenticity determination. .

<Effects of the Invention> As explained above, according to the present invention, even if the data on the card is copied, as long as the information for determining authenticity recorded by the phosphor on the card is not copied, accurate determination of authenticity is possible. Become.
