DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a technology for issuing usable cards by specifying usable devices or issuing usable devices by specifying usable cards between a card and a device using the cards, and When using a card, it belongs to the technical field of validity confirmation for identifying whether the card or device can be used.

[0002]

2. Description of the Related Art Conventionally, sale of goods and provision of services using cards have been carried out as a general transaction form. Payment systems using cards can be broadly divided into prepaid (prepaid) and postpaid (credit). In each case, the mainstream is to use a terminal to read the information on these cards. , The terminal is owned by the seller that provides the product or service (installed in stores, etc.)
However, the card is operated by an individual who is a user.

The "non-stop automatic toll collection system" for highways and the like, which has recently attracted attention, has been developed by combining a technology that is an extension of this technology with a communication system. There is a significant difference in that the terminal is not owned by the seller (toll booth), but is owned by the user (mounted on an automobile or the like).

In this case, a personal identification method using a personal identification number (PIN) is generally used as means for preventing unauthorized use of the card due to theft or loss, for example. ) Is often simple and easy, such as the date of birth, and is unlikely to be a decisive factor in preventing unauthorized use.

[0005] In the above-mentioned "non-stop automatic toll collection system", inputting a personal identification number (PIN) for user confirmation every time the vehicle passes through a toll booth is extremely inconvenient. There are problems such as
There is a need for a technology that is more convenient and that has a high probability of preventing unauthorized use of cards and terminals.

[0006]

SUMMARY OF THE INVENTION The present invention provides a mechanism for preventing a stolen or lost card from being illegally used, and a "non-stop automatic toll collection system" or a system for receiving Internet settlement, satellite broadcasting, CATV, In the case of e-commerce systems, etc., when a user owns a terminal equipped with unique or unique identification information on the device itself, preventing unauthorized use without impairing its convenience,
It is an object to provide a technology for ensuring safety.

[0012]

[Embodiment 1] In this embodiment, a "non-stop automatic toll collection system" can be settled without stopping a vehicle at a tollgate to pay a toll on a toll road.
The card issuing system used in the embodiment will be described.

A conventional method of paying a toll on a toll road is to receive a toll ticket at the entrance of a toll road, submit the toll ticket at a toll booth at an exit, and pay a fee corresponding to the toll section in cash or a prepaid card, credit card. Generally, a method of paying by a card, a coupon, or the like is used. According to such a method, the vehicle must be temporarily stopped in order to pay the toll, so that when the traffic volume is large, the vicinity of the tollgate becomes extremely congested. In contrast, the non-stop automatic toll collection system has a dedicated vehicle-mounted device, which is a means of communication with the toll booth, installed in each vehicle, and is the same as a toll payment procedure at the entrance and exit of toll roads. Since the communication of the function is performed and the toll according to the toll section is calculated instantaneously, the toll can be paid without stopping the vehicle at the exit toll booth if the speed is below a certain speed.

In order to use this system, an onboard device mounted on the vehicle and a card on which information on payment of a toll is described are used. When a customer wants to use the "non-stop automatic toll collection system", he first purchases an on-board unit to be mounted on his vehicle. In the vehicle-mounted device, a serial number different for each vehicle-mounted device is stored in a non-rewritable storage unit during the manufacturing process. For example, the serial number “11111” is stored in the serial number storage unit 32 of the vehicle-mounted device 30.
It is assumed that “1” is stored. The customer who has purchased the vehicle-mounted device 30 has a serial number “111111” of the vehicle-mounted device 30.
And apply for issuance of the card 10.

At the card issuing window, a card in which the serial number is described in advance in the serial number entry column 11 for each card is prepared. The serial number need not be unique to every card, but the lower the appearance rate of the same serial number, the higher the probability of card fraud prevention. The issuer receiving the card 10 issuance request from the customer arbitrarily selects, for example, a card having a serial number of “222222” from the cards prepared in advance.
The card is loaded into the reader / writer 21 of the card issuing device.

Next, when the customer inputs the serial number “111111” of the vehicle-mounted device used by the customer through the input device 22, the card issuing machine inputs the serial number “222222” of the card read from the card reader / writer 21. The third identification information “333333” indicating the validity is derived from the serial number “111111” of the card and written in the third identification information entry column 12 of the card. These processes are similarly performed on the vehicle-mounted device when the vehicle-mounted device is sold (issued).

If the customer wishes to pay the toll with a credit card, the customer's credit card number is further input from the input device 22 and written in the credit card number entry field 13 of the card. Issue In the case of a card of the prepaid (prepayment) method, since the monetary value information is stored in the card in advance, there is no need to write the information when issuing the card. Further, in the case of a card capable of replenishing a monetary value (value) such as electronic money, the card holder may arbitrarily replenish the card with necessary monetary value information after the card is issued.

As described above, the third identification for identifying the validity of the vehicle-mounted device used by the customer in the "non-stop automatic toll collection system" and the serial number of the card used in the vehicle-mounted device. By creating information, even if a third party attempts to use the lost card with the onboard unit installed in his vehicle, the serial number of the card, the serial number of the onboard unit, and the third identification information can be consistent. Because there is no unauthorized use, unauthorized use can be prevented. Further, since the serial number and the serial number of the other party are not stored in the card and the on-vehicle device, security can be ensured with a high probability even if one of them is stolen or lost.

[0019]

[Second Embodiment] A second embodiment describes a card use system in a "non-stop automatic toll collection system" in which payment for tolls on a toll road can be made without stopping vehicles at a tollgate. .

When using the "non-stop automatic toll collection system" using the card issued in the first embodiment, the customer describes the serial number "111111" and the third identification information "333333" for identifying validity. Card 1
0 is loaded into the reader / writer 31 of the vehicle-mounted device 30 having the serial number “222222”. Of course, the third identification information "333
333 "may be described in the vehicle-mounted device.

The vehicle-mounted device 30 reads the serial number “111111” and the third identification information “333333” of the card 10 from the reader / writer 31, and reads the production number “222222” of the vehicle-mounted device from the production number storage unit 32.
The processing unit 33 derives the third identification information from the serial number and the serial number, compares the third identification information read from the card, and permits the use of the card if they match, and if not, Refuse to use the card. When the third identification information “333333” is described in the vehicle-mounted device, the third identification information whose consistency is to be checked is read from the vehicle-mounted device.

As a second method, the serial number "222222" of the vehicle-mounted device is obtained from the third identification information "333333" and the serial number "111111", and is compared with the serial number "222222" read from the vehicle-mounted device. If they match, the use of the card is permitted, and if they do not match, the use of the card is rejected. As a third method, the serial number “111111” is obtained from the third identification information “333333” and the serial number “222222” of the vehicle-mounted device.
Is compared with the serial number “111111” of the card, and if they match, the use of the card is permitted, and if they do not match, the use of the card is rejected. These comparison and rejection may be performed by either the card or the vehicle-mounted device, and the permission or rejection of use of the card may be either permission or rejection.

Next, the customer enters the serial number "11111".
Suppose that the third person who lost the card of "1" and picked up the card tried to use the card with his or her own vehicle-mounted device. The manufacturing number of the vehicle-mounted device owned by the third party is “555555”, and the serial number of the picked-up card is “111111”
Since the third identification information “333333” for identifying the validity of the card is loaded into the vehicle-mounted device, when the validity of the card is checked by the first method, the serial number of the card is “111111”. The serial number of the vehicle-mounted device "555
555 ”to obtain the third identification information“ 666666 ”,
The third identification information “33333” written on the card
Since the result of comparison with "3" does not match, use of the card is rejected. This validity check method has the same result in the second and third methods, so the same applies to the case where the use of the card is rejected and the third identification information is described in the on-board unit. In addition, it is possible to prevent financial damage to a customer who has lost the card or a customer who has stolen the vehicle-mounted device.

After the validity of the card is confirmed and the use of the card in the vehicle-mounted device is permitted, the customer passes through the entrance gate dedicated to the non-stop automatic toll collection system on the toll road, and the customer enters between the vehicle-mounted device and the gate. Performs wireless communication and records the information of the entrance tollgate on a card, on-board unit or non-stop automatic toll collection system.

When a vehicle passes through a dedicated gate installed at the exit of a toll road, a toll corresponding to a section of travel is similarly calculated between the vehicle-mounted device and the gate. When the credit card number stored in the card is notified to the automatic toll collection system, it is confirmed whether or not the credit can be used. If the use of credit is not possible, the stop of the vehicle is instructed by the gate breaker, and if the use of credit is possible, the toll is sent to the credit card company as a credit transaction. And pay along with the general credit card usage fee.

In the case of a card in which a monetary value is recorded on a card such as a prepaid card or electronic money, and a toll is deducted from information stored in the card when passing through a toll gate, the remaining storage amount of the card is the toll If it is less than, the vehicle will be instructed to stop by the gate breaker, and will pass through the gate with a shortage fee paid separately.

In the embodiment, the first identification information is described as the serial number of the card, and the second identification information is described as the serial number of the vehicle-mounted device. As described above, the serial number of the card does not need to be unique to all the cards, but the magnitude of security differs depending on the appearance rate of the same serial number, and the second identification information is also different. It is not necessarily required to be the serial number of the vehicle-mounted device. However, as in the case of the card serial number, it goes without saying that the smaller the appearance rate of the second identification information, the higher the security level.

The card is not necessarily issued by a dedicated issuing machine. For example, when purchasing a vehicle-mounted device and a card at the same time, the card can be issued using the purchased vehicle-mounted device. In this case, since the serial number corresponding to the second identification information can be read from the storage unit, there is no need to input the serial number from the input device.
A card can be issued easily. The validity of the card or the validity of the vehicle-mounted device can be confirmed by the vehicle-mounted device or by the card by using an IC card or the like.

As methods for further improving security, information stored in the card is encrypted, and personal identification information (PIN) for recognizing that the card is owned is stored in the card or the vehicle-mounted device. It is one of the effective methods to combine the method of requesting the input of the personal authentication information when the card is loaded in the vehicle-mounted device and comparing them.

[0030]

Embodiment 3 In Embodiment 3, a decoder (decoding device) used to view a digital broadcast with data compression or a scrambled broadcast such as CATV and a card (credit card, cash card, An example is shown in which the present invention is applied to a digital broadcast decoder and a card used in the decoder in a mail order service system provided using a debit card, an electronic money card, and the like.

When a customer wants to receive digital broadcasting, the customer must purchase a dedicated decoder 40 for decoding the compressed and transmitted digital broadcasting signal wave and make a receiving contract with a broadcasting company.

In the non-rewritable storage section of the dedicated decoder, identification information unique to each decoder is stored and sold. This is used as information for specifying a decoder so that only a decoder owned by a customer who has made a reception contract with the broadcasting company normally operates the decoding function.

For example, the identification information "500123" is assigned to the decoder 40 purchased when the customer makes a reception contract with the broadcasting company.
It is assumed that “4” has been stored in the identification information number storage unit 53.

Normally, the identification information of the decoder is displayed in a visible state such as the decoder body and an outer box for packing or a warranty card.
01234 "and the card number" 21212112 "used in the mail-order service are presented together at the window of the broadcasting company to make a reception contract.

At the window of the broadcasting company that accepts the application for the reception contract from the customer, the inquiry to the credit company is made as to whether or not the customer's card number can be used. The card for mail order to be sold is loaded into the reader / writer of the card issuing device, and the identification information “5001” of the decoder is input from the input device.
234 "and the card number" 21212112 ".

The card issuing device checks the input decoder identification information "5001234" and the card number "212".
The third identification information “7122446” is derived from “1212” and stored in the third identification information storage unit of the card to issue a mail-order card. In this case, it is necessary to store the credit card number on the card in addition to these processes.

A credit card number is stored in the card to be issued in advance, and this number may be used as the card number. In this case, the card issuing device reads the credit card number from the storage unit of the card, inputs the identification information of the decoder, derives the third identification information, stores the third identification information, and issues the mail-order card. The way to do it.

When a decoder is sold at a contract window of a broadcasting company, a mail order card can be issued using a decoder purchased by a customer instead of a dedicated card issuing device.

In this case, the card to be issued is loaded into the reader / writer of the decoder, the identification information is read from the identification information storage section of the decoder, and the credit card number is inputted from the input device, whereby the third identification information is obtained. Then, the third identification information can be stored on the card or the third identification information can be stored in the customer's decoder to issue the card for mail order. Also, when issuing a card using this decoder, it is also possible to issue a mail order card using a card in which a credit card number is stored in advance in the same manner as in the above method.

The credit card number and the third identification information are stored in the mail order card thus issued, and the identification information unique to the decoder is stored in the decoder. At the time of use, the decoder determines that the consistency is obtained by determining the consistency between the identification information stored in the decoder itself, the credit card number read from the mail order card, and the third identification information. If so, the use of the mail order service is permitted. Further, the third identification information may be stored in the decoder, or the card may determine the consistency by using an IC card or the like.

The method of judging the compatibility between the decoder and the card for mail order and permitting the use of the mail order service can also be used to decide whether to permit viewing of the broadcast itself.

That is, the essence of the technology of the present invention is that, in the relationship between a card and a system using the card, when specifying an available card, it is determined whether or not the card and the card using device mutually recognize each other. The present invention can be applied to determination of a relationship between a decoder for decoding a digital broadcast signal described in this embodiment and a card which can use a mail order service using the decoder. .

In the event that the mail-order card is lost, even if a third party who picks up the card inserts the card into its own decoder and tries to use the mail-order service illegally, Since the card stores the credit card number of the original owner and the third identification information derived from the identification information of the decoder, there is no consistency with the identification information of different decoders, and it is not possible to use the card. Can be refused.

In this manner, it is possible to prevent economical loss due to the theft of the decoder body or the loss or theft of the mail-order card, thereby providing a highly secure system. Furthermore, in consideration of the case where both the decoder body and the card for mail order are stolen or lost, security is double applied to each card for mail order or each decoder, such as a personal identification number. Needless to say, it will increase further.

The scope of application of the present invention is not limited to the case shown in the embodiment, but may be the relationship between an electronic money card and an electronic money replenishing device / electronic money exchange device, the relationship between a card-type telephone and a card, and home banking. Relationship between terminal device and card used in the Internet, relationship between Internet connection device and card, relationship between electronic ticket terminal device and card, relationship between cash dispenser and card, relationship between ATM and card, relationship between wireless device and card, etc. It can be used for determining the consistency between cards and devices / systems using various cards.

The present invention is effective as a means for checking the validity between a card and a terminal using the card as shown in this embodiment, and in particular, the purchase and sale of goods and payment of services. In the system for
It is effective in securing security against financial loss due to leakage or exploitation of important information about the payer to a third party.

[0047]

As described above, according to the present invention,
By checking the consistency of the first, second, and third identification information, it becomes possible to control whether or not the card use device functions, thereby preventing the use of stolen or found cards. I can deal with it. Further, there is no demerit such as forgetting or leaking of a password or a decrease in convenience due to an input operation as in the authentication method by inputting a password.
