Abstract

PURPOSE: An approval method of an ETC(Electronic Toll Collection) system using a wireless public key is provided to miniaturize a size of an OBU(On Board Unit) by collecting toll without using a smart card. CONSTITUTION: An initialization process is performed when a vehicle having an OBU(On Board unit) approaches a tollgate(S301,S302). The credit card information, the private information, and the authentication information are transmitted to a roadside equipment(S303,S304). The roadside equipment transmits the credit card information, the private information, and the authentication information to an ETC system server and compares the received authentication information with the stored authentication information(S305-S307). Approval information is transmitted to the OBU if the received authentication information corresponds to the stored authentication information(S308). The ETC system stores the approval information and completes an approval process by using the credit card information and the private information(S309-S315).

Description

Method of ETC accounting with wireless public key infrastructure

The present invention relates to an electronic toll collection system (ETC) service using a dedicated short range communication (DSRC) method, and in particular, to minimize payment time without installing a smart card in an onboard unit (OBU). The present invention relates to a wireless public key based ETC payment method.

Wireless Public Key Infrastructure (WPKI) is a wireless authentication method that can solve real-time identification, as well as anxiety of leaking and forgery of credit card number or personal financial transaction information. By using a certificate, you can access a wired / wireless portal site to verify your identity in real time and to provide secure wireless e-commerce without worrying about information leakage or forgery or alteration of your credit card number or personal financial transaction information. .

In addition, the ETC system is an electronic toll payment system, which is capable of automatically paying the toll through the exchange of information between a vehicle mounted on a toll gate such as a toll gate and a roadside base station installed in the toll gate.

1 is a block diagram showing the configuration of an ETC system.

Referring to FIG. 1, a vehicle mounting apparatus 110 mounted on a vehicle to transmit and receive a radio signal, and a roadside base station (RSU) installed around a toll gate and a road to wirelessly communicate with the vehicle mounting apparatus 120, a vehicle detector 130 for detecting a vehicle type by scanning a height, a length, and a width of the vehicle passing through the toll gate, and a vehicle detector 130 and a roadside base station 120 connected to the vehicle for payment In order to process and database the information from the onboard device to the lane controller 140, a camera 150 for photographing a vehicle that is not paid or violated from the vehicle passing through the ETC system, and the automatic payment after the result Is connected to the lane controller 140 and the network, the information is from the total lane controller 140 to the database And the local server (170) for managing all operators in conjunction with a server, connected to the settlement fee by credit card is configured to include a credit card payment system (180) for providing an authentication procedure, and credit card information.

Toll payment method in the above system is made in the following order.

2 is a flowchart illustrating a data flow of a payment method in a conventional ETC system.

Referring to FIG. 2, when the vehicle enters the toll gate of the toll road and enters the communication area of the roadside base station 120, the vehicle receives an initialization request message broadcasted by the roadside base station 120 (S201), and the vehicle together with the response message. The serial number and vehicle information of the payload device 110 are transmitted to the roadside base station 120 (S202).

In addition, when the vehicle enters the toll gate, the vehicle model detector 130 scans the length, height, width, and the like of the vehicle to inquire the vehicle model, and transmits the inquired vehicle model information to the lane controller 140 (S203).

In addition, the vehicle type information transmitted from the vehicle mounting apparatus 110 in step S202 is transmitted to the lane controller 140 (S204).

The lane controller 140 receiving the vehicle information transmitted from the vehicle type detector 130 and the roadside base station 120 checks whether the two vehicle information is identical (S205).

In addition, the roadside base station 120 requests the payment information for the payment on the vehicle mounting apparatus 110 (S206), after receiving the payment information in a response message (S207), and transmits to the lane controller 140. (S208). At this time, the payment information includes balance information and personal information of the smart card inserted in the vehicle-mounted device 110.

The lane controller 140 receiving the payment information settles the fee by subtracting the payment fee from the smart card balance (S209), and transmits the settlement result to the roadside base station 120 (S210). To be delivered to (S212). In addition, to update and store the result of the fare settlement in the database of the lane controller 140 (S211).

In addition, the vehicle mounting apparatus 110 receiving the settlement result changes and updates the balance information of the smart card (S213), and transmits a response message to the roadside base station 120 to complete the payment (S214).

The smart card is a rechargeable prepaid card, and charges a predetermined amount in advance, and the balance is subtracted each time it is inserted into the vehicle mounting apparatus 110, and when the balance is insufficient, the smart card can be charged semi-permanently.

However, the payment method using the smart card is limited to the miniaturization of the vehicle loading device because the device for inserting the smart card should be additionally configured in the vehicle loading device, and the user has to check the balance and recharge it. There is this.

Therefore, a method of making a credit card payment using a mobile communication terminal instead of the smart card may be used.

That is, when the mobile communication terminal is connected to the on-vehicle device and enters the toll gate, the user operates a button through the mobile communication terminal in connection with the credit card payment system 180 through communication with the mobile communication system base station. The credit card payment authorization is to be settled.

However, as described above, the credit card payment method using the mobile communication terminal must first have a mobile communication system in the toll gate, and the user authentication process with the credit card payment system is complicated and takes a long time.

In order to solve the above problems, the present invention is to store the personal information, vehicle information and credit card information, etc. in advance in the vehicle on-board device, and to store specific certificate information for authentication in order to settle the charge in the ETC system By providing a wireless public key-based ETC payment method that enables users to make a payment quickly by using a wireless public key authentication method and to achieve miniaturization by not having to install a smart card on a vehicle-mounted device. have.
