Description

Payment data transmission method through Bluetooth communication, payment data transmission terminal and payment data processing system using the same

The present invention relates to a payment data transmission method, payment data transmission and reception terminal and payment data processing system using the same, and more particularly, to a payment data transmission method through Bluetooth communication, payment data transmission and reception terminal and payment data processing system using the same. .

Background Art [0002] With the spread of user terminals such as smart phones having a short range wireless communication function, functions of transmitting and receiving data related to various payments, such as mobile credit card / credit card functions and point card functions, are mounted on user terminals.

Accordingly, as a data processing device for transmitting, receiving and processing payment data required for a user terminal such as a smart phone, a payment data processing device for processing payment related information such as payment information and point information has been widely used.

NFC payment system is implemented as a NFC-based payment system, NFC technology is applied to the RFID terminal is applied to receive and process the transmission and reception of data of the required information with the user terminal utilizing ultra short-range wireless communication technology through the NFC reader equipped There are a lot of payment data processing apparatus built-in.

However, in the case of the payment data processing apparatus embedded with the NFC reader, there is a side in which information is exchanged only when the reader is in contact with the reader. However, the contact with the reader is a weak point in terms of usability.

In particular, the user information such as card information used for payment is transmitted to the payment system, and the payment system receives the payment information from the payment system. There is a fundamental limitation in dealing with various mobile payments.

On the other hand, Bluetooth communication based technology has the advantage that the Bluetooth module or function is installed in almost all the user terminal as described above, various mobile payment methods by receiving and processing payment-related data from the payment system in the user terminal as needed It has the advantage of being able to cope with the problem, and as a Bluetooth communication-based technology, various low-power Bluetooth (Bluetooth Low Energy) technology including beacon technology is recently utilized, and various services such as location-based service using BLE technology are available. Development is planned.

Accordingly, attempts have been made to develop a new Bluetooth communication based payment method and system for transmitting or receiving payment related information such as payment information and point information through Bluetooth communication, including a payment data processing device equipped with a Bluetooth communication module. It is becoming.

However, when transmitting payment data using a BLE technology beacon (Beacon) when using a beacon signal (Beacon) due to the broadcasting process (Beacon) due to the broadcasting process (Broadcon) process, it has the advantage of simple data transmission without pairing However, due to the characteristics of the beacon signal being broadcast, the security of the data is not secured, and important payment data is because the device sending the beacon cannot identify a specific user terminal to receive or directly check whether the data is received. There is a problem that is not suitable for the transmission of.

On the other hand, in the case of general BLE communication in which a search, a search response, a connection request and a connection request response, a connection, and a data communication are performed, a communication channel between both terminals is shared through a shared secret key by sharing a secret key (a unique number). The actual problem that vulnerabilities are vulnerable to hackers' sniffing attacks is because the encryption technology is not applied in a basically formed manner, but apart from that, since the data is transmitted after the above connection and data communication process, the connection and reconnection There is a problem that a delay occurs in the transmission of the initial data due to repeated attempts to connect the data.

The problem of delay in the transmission of the initial data as described above is that, once the payment data is required to be transmitted to the user terminal via Bluetooth communication and subsequent data processing is performed at the user terminal, for example, payment data processing for mobile payment. In the device, a delay in payment processing is caused, thereby causing inconvenience to the user and a decrease in reliability of the payment processing. In particular, when there is a limitation of the distance from the user terminal to the payment data transmission, that is, when the user terminal restricts the transmission of the payment data only at a short distance close to the payment data processing apparatus, the user terminal once in the connection and reconnection process. The user is recognized that the payment has been completed by the proximity of the payment data processing apparatus to bring the user terminal back to the original position, and a request for the user to close the user terminal again is required, resulting in inconvenience of the user. Due to this repetitive behavior and data transmission, errors in the payment data inevitably occur along with a decrease in the reliability of payment and payment processing.

Accordingly, due to the above-described problems of general BLE communication, which proceeds with connection and data communication with beacons and user terminals of BLE technology, BLE communication is spreading and spreading because all user terminals are equipped with Bluetooth functions. Although it has a great advantage of ease, it has not been actively used in a payment data processing system that transmits important payment data in addition to general data communication.

1 is a configuration diagram of a payment data processing system using a payment data transmission method through Bluetooth communication according to an embodiment of the present invention.

The payment data processing system of the present embodiment uses the payment data transmission method through the Bluetooth communication of the present invention or is used in the implementation of the payment data transmission method, and the payment data transmission / reception terminal 100 and the data processing device body performing the Bluetooth communication function. It consists of 200.

The area of the payment data processing system according to the present embodiment receives a signal detection area in which the user terminal 300 can detect a beacon signal or a Wifi signal with a preset reception distance and a BLE signal transmitted for transmission of payment data. It is set by dividing it into a payment area which is a proximate area.

The Bluetooth communication module for transmitting the BLE signal of the payment data transmission / reception terminal 100, for example, the first BT module of FIG. 1, is configured to limit the signal transmission distance to a predetermined short distance to set up a payment area that is a proximate area.

 Basic functional features of the payment data transmission / reception terminal 100, the data processing apparatus main body 200, and the user terminal 300 will be described first.

The payment data transmission / reception terminal 100 transmits / receives data of information required by being connected to the data processing apparatus main body 200 through wired / wireless communication, and includes two or more Bluetooth communication modules to be used by the user terminal 300 and Bluetooth communication. It performs a function of transmitting and receiving a BLE signal of data of information.

The payment data transmission / reception terminal 100 performs a function of transmitting and receiving a BLE signal and a beacon signal of data of information required through a Bluetooth communication to the user terminal 300, and the transmission and reception of the BLE signal and the beacon signal Transmission is controlled by the command of the data processing apparatus main body 200.

According to an embodiment, the payment data transmission / reception terminal 100 may include two or more Bluetooth communication modules, and in the present embodiment, the data transmission / reception terminal 200 of the present embodiment may be configured according to a control command of the data processing apparatus main body 200. Including two Bluetooth communication modules that are selectively controlled and independently operated, one Bluetooth communication module, for example, the first Bluetooth communication module 111a generates a BLE signal for transmitting data of required information, that is, payment data, which will be described later. For example, the second Bluetooth communication module 111b may be implemented to generate and transmit a beacon signal having a specific function to be described later.

In this case, the first BT module 111a of FIG. 1, which is a Bluetooth communication module that transmits a BLE signal of the payment data transmission / reception terminal 100 to set up a payment area that is a proximate area, is set to have a signal transmission distance limited to a predetermined short distance. The second Bluetooth communication module 111b that generates and transmits a beacon signal having a specific function is set to be limited to a distance that the signal transmission distance covers a predetermined distance, for example, an interior area of a store.

In the transmission of payment data, the payment data transmission / reception terminal 100 receives BLE transmission data from the data processing apparatus main body and includes the BLE transmission data as advertising data of BLE communication through a Bluetooth communication module. A BLE signal is generated and transmitted in a characteristic manner of transmitting a BLE signal of an advertising packet.

At this time, the payment data transmission and reception terminal 100 is in the advertising state (Advertising State) in the Bluetooth communication.

According to an embodiment, the BLE signal may be transmitted when a preset operation of a user or a user terminal is recognized. In this embodiment, one or more muscle roughness sensors are used, and the preset operation is a preset distance. It is configured to enter the user or the user terminal to the point within the configuration to transmit the payment data only when the operation of entering the user or the user terminal to the point within a predetermined distance by the proximity sensor is configured. do.

In addition, according to the exemplary embodiment, it may be configured to simply determine whether the user or the user terminal is close to the payment data transmission / reception terminal 100, and transmit the payment data only when the proximity is close. In this case, one roughness sensor Or it can be implemented as a simple light sensor.

* Here, the information required for generating payment data is payment related information, and includes a payment amount and a payment method according to the purchase of goods from the user of the affiliated store through a user interface (not shown) in the data processing apparatus main body 200. Receives one or more selected from the payment information and the point information that is information required for the use and earning process of the point, generates the payment data according to the information input from the user, generates BLE transmission data including this to send and receive payment data The transmission to the terminal 100 is used.

The advertising data is included as a protocol data unit (PDU) of the advertising packet.

The transmission of the BLE signal is performed in the advertising state according to the current BLE standard, for example, BLUETOOTH SPECIFICATION Version 4.2. In the advertising state, the link layer is used in the advertising state. Enables the transmission of advertising packets. In addition, in the advertising state, the scan request may be responded to a scan request.

If you stop advertising, you can go back to Standby State, and if you receive a Connect Request from a device that was in the Initiate State, enter the Connect State. You may.

The advertising state is one of the following types.

Connectable Undirected Event

Connectable Directed Event

Non-connectable Undirected Event

Scannable Undirected Event

Events in the advertising state (Advertising State) are defined as shown in Table 1 below.

Advertising Event Type Related PDU Allowable response PDU SCAN_REQ CONNECT_REQ Connectable Undirected Event ADV_IND Yes Yes Connectable Directed Event ADV_DIRECT_IND No Yes Non-connectable Undirected Event ADV_NONCONN_IND No No Scannable Undirected Event ADV_SCAN_IND Yes No

In the present invention, since a user terminal to receive payment data is not specified, a connectable undirected event and a scannable omnidirectional event, except for a connectable directed event, are scannable. The BLE signal may be transmitted as an event selected from an undirected event or a non-connectable undirected event.

Accordingly, the advertising data including payment data may be protocol data units of a connectable undirected event and protocol data of a scannable undirected event according to a specified event. Recorded in the AdvData field of a protocol data unit (PDU) of a unit, or of a Non-connectable Undirected Event.

Each constitutes a different embodiment as follows.

In the first embodiment in which the BLE signal is transmitted as a connectable undirected event in the payment data transmission / reception terminal 100 of the present invention, the connectable undirected event (ADV_IND) receives the same.

Unlike the normal BLE communication, when the response is normally received, the payment data transmission / reception terminal 100 and the user terminal 300 do not enter a connection state, but terminate the advertising event and the BLE communication.

Meanwhile, in the second embodiment in which a BLE signal is transmitted as a non-connectable undirected event, a non-connectable undirected event Since the ADV_NONCONN_IND does not request or receive a response from the user terminal 300 that receives the ADV_NONCONN_IND, the payment data transmission / reception terminal 100 performs an advertising event at a preset number of times and a period, thereby providing an advertising packet. packet), and terminate the advertising event and the BLE communication.

In addition, the payment data transmission / reception terminal 100 of the present invention may transmit a BLE signal as a scannable undirected event, and in the third embodiment, a scannable undirected event (ADV_SCAN_IND) ) Sends a scan request (SCAN_REQ) to the user terminal, which is a scanner, to obtain additional information from the payment data transmission / reception terminal 100, which is an advertiser.

Therefore, the payment data transmission / reception terminal 100 sending the ADV_SCAN_IND waits for the scan request SCAN_REQ on the advertising channel sending the ADV_SCAN_IND. Terminates the activating event and the BLE communication without performing any additional procedure.

Accordingly, in the present invention, unlike the general BLE communication, when the response to the activating is normally received through the first and third embodiments, the present invention does not enter the connection state, but the activating event. And terminating the BLE communication.

Meanwhile, in the second embodiment, an advertising event is performed to transmit an advertising packet for a predetermined time at a predetermined number of times and a period regardless of the reception of a response, and the predetermined time ends. In the case of terminating the advertising event and the BLE communication is characterized by a differentiation.

This fundamentally solves the problem of delay due to connection and reconnection of the BLE communication in the transmission of payment data, and reduces the possibility of payment data being received from other user terminals, thereby preventing errors in payment data processing.

Hereinafter, an embodiment of a payment data transmission method through Bluetooth communication of the present invention will be described in detail with reference to FIGS. 5 and 6.

5 is a flowchart illustrating a payment data transmission method through Bluetooth communication of the present invention, and FIG. 6 is a detailed flowchart illustrating a payment data transmission method through Bluetooth communication according to the present invention.

As shown in FIG. 5, the payment data transmission method through the Bluetooth communication of the present invention is a data transmission method through the Bluetooth communication of the payment data transmission and reception terminal as described above, and basically generates payment data according to user input. Data generation step (S200), BLE transmission data generation step of generating the generated payment data as BLE transmission data to be transmitted as a BLE signal (S300), BLE signal transmission step of transmitting the generated BLE transmission data as a BLE signal (S400) ), And is performed by the payment data transmission and reception terminal 100 and the data processing apparatus main body 200 of the payment data processing system as described above.

The BLE transmission data is advertising data of BLE communication, and the BLE transmission data generating step S300 generates advertising data including the payment data and generates a BLE signal. The transmitting step S400 transmits a BLE signal of an advertising packet including advertising data.

In addition, the user terminal 300 is equipped with an application for activating the Bluetooth communication function of the user terminal in response to the reception of a preset signal, and the user terminal function activation step (S100) for transmitting the preset signal to a predetermined area; In addition, in the present embodiment, the preset signal is a Bluetooth beacon signal or a Wi-Fi signal, and the beacon signal and the Wi-Fi signal are transmitted so that a user terminal entered in a preset signal detection area such as a store can be received. The range may be preset, and the command or data for enabling the application mounted on the user to activate the Bluetooth communication function is included, or the command or data for activating a specific payment application is included and sent accordingly. Beacon signal again The user terminal receiving the Wi-Fi signal causes the mounted application to activate the Bluetooth communication function or to activate a specific payment application.

In addition, when a response from the user terminal to the BLE signal including the advertising data (Advertising data) is received, further comprising a BLE end step (S500) to terminate the transmission of the BLE signal or terminate the BLE communication Can be.

Specifically, in the first embodiment in which the BLE signal is transmitted as a connectable undirected event in the payment data transmission / reception terminal 100, the user terminal 300 that receives the BLE signal is a scanner or an initiator. In case of the third embodiment which responds with a scan request (SCAN_REQ) or a connect request (CONNECT_REQ), and sends a BLE signal as a scannable undirected event, Since the terminal responds with a scan request (SCAN_REQ), the payment data transmission and reception terminal 100, which is an advertiser, accordingly, when the response is received, terminates the transmission of the BLE signal or terminates the BLE communication (S500). Can be done.

On the other hand, in the second embodiment in which the BLE signal is transmitted as a non-connectable undirected event, the user terminal 200 does not send any response, and thus, for a predetermined period and time. After transmitting the advertising packet (Advertising packet) and the predetermined time elapses, the BLE termination step (S500) of terminating the transmission of the BLE signal or terminating the BLE communication may be performed.

The payment data generation step (S200) includes a process of receiving, from a user, at least one selected from payment information including a payment amount and a payment method according to an item purchase, and point information which is information required to use and accumulate points. In the process of generating the payment data according to the information input from the user, a payment including a payment amount and payment method according to the purchase of goods from the user of the merchant through the user interface (not shown) of the data processing apparatus main body 200 Receives at least one selected from the information and the point information, which is information required for the use and accumulation of points, and may receive a separate payment request.

Among the point information, the point accumulation information required for the point accumulation process may be automatically calculated in a preset method according to the input of the payment information and included in the payment data.

According to an embodiment, the payment data generation step (S200) may generate payment data by encrypting a part of one or more pieces of information selected from the input payment information and point information, and considering the efficiency with security, the encryption The information may be encrypted using an OTP (One time password) method using at least one of a device identifier and a transaction date and time of the payment data processing device main body.

Accordingly, when the payment data of the embodiment of the present invention as described in FIG. 2 is generated and the payment data of FIG. 2 is encrypted, the device ID (Device ID), transaction date and time, and random number of the payment data processing apparatus main body are encrypted. to be.

In addition, the size (0 to 31 bytes) of the AdvData region of each Protocol Data Unit (PDU) in which the payment data is to be recorded is considered. In this embodiment, the size of the payment data is set to the Protocol Data Unit (PDU). It is created as a structure having the total size (29 bytes) smaller than the size of AdvData area of the unit).

In addition, as described above, the entire payment data generated by encrypting a part of the information may be encrypted again through a known encryption algorithm to improve the security of the information. This means that the BLE communication is simply a secret key (a unique number consisting of numbers). The communication channel between the two terminals is formed by sharing the shared secret key, and basically the encryption technology is not applied to compensate for the realistic problem that it is vulnerable to security such as sniffing attack.

The BLE transmission data generation step S300 is a process of generating advertising data including the payment data and associated with an advertising state preset in the data processing apparatus main body 200. Produced in a form suitable for a Protocol Data Unit (PDU).

The advertising packet has a structure of an advertising packet of a general current BLE standard, for example, BLUETOOTH SPECIFICATION Version 4.2, as shown in FIG. 2, and is included in an AdvData region of each protocol data unit (PDU). Payment data is recorded.

The BLE signal transmitting step (S400) may include an advertising packet including the advertising data as a protocol data unit (PDU) of an advertising packet. It generates and sends a BLE signal of the advertising packet.

In the first embodiment in which the BLE signal is transmitted as the Connectable Undirected Event in the payment data transmission / reception terminal 100 described above, a protocol data unit (PDU; Protocol) of the advertising packet (Advertising packet) is transmitted. Data Unit) is set as a protocol data unit of a Connectable Undirected Event, and the BLE signal transmission step S400 may transmit the BLE signal as a connectable omnidirectional event.

In this case, the Connectable Undirected Event (ADV_IND) sends a scan request (SCAN_REQ) or a connection request to the user terminal 300 that receives it as a scanner or an initiator. (CONNECT_REQ) to respond, the payment data transmission and reception terminal 100 waits for a response from the user terminal 300 after transmitting the BLE signal, if there is no response for a predetermined time of the BLE signal of the advertising packet The transmission may be performed to repeat a preset number of times and a period or to terminate the advertising event.

Accordingly, in the present invention, unlike the general BLE communication, when the response to the activating is normally received through the above-described first and third embodiments, the present invention does not enter the connection state, but does not enter the eddy state. In the second embodiment, the terminating event and the BLE communication are terminated by performing an advertising event to transmit an advertising packet for a predetermined time and a predetermined number of times regardless of the response. And, if the preset time is terminated is characterized by terminating the advertising event and BLE communication.

This fundamentally solves the problem of delay due to connection and reconnection of the BLE communication in the transmission of payment data, and reduces the possibility of payment data being received from other user terminals, thereby preventing errors in payment data processing.

According to the embodiment, as in the second embodiment in which the BLE signal is transmitted in the above-described non-connectable undirected event, the advertising packet is transmitted. A protocol data unit (PDU) is set to a protocol data unit of a non-connectable undirected event, so that the BLE signal transmission step S400 is not connectable. It is also possible to send a BLE signal as an omnidirectional ethanizing event.

In this case, since the non-connectable Undirected Event (ADV_NONCONN_IND) does not request or receive a response from the user terminal 300 that has received it, the payment data transmission / reception terminal 100 is preliminary. An advertising packet is transmitted for a predetermined period and time, that is, a predetermined number of times and a period, and the advertising event is terminated.

In addition, according to an embodiment, as in the third embodiment of transmitting the BLE signal as the scannable undirected event in the payment data transmission / reception terminal 100 described above, the advertising packet (Advertising packet) Protocol data unit (PDU) is set to a protocol data unit of a scannable undirected event, and the BLE signal transmission step S400 transmits a BLE signal as a scannable omnidirectional event. You may.

In this case, the scannable undirected event (ADV_SCAN_IND) sends a scan request (SCAN_REQ) to the scanner user terminal so as to obtain additional additional information from the payment data transmission / reception terminal 100 which is an advertiser. Since the payment data transmission and reception terminal 100 transmits the BLE signal, waits for a response from the user terminal 300, and if there is no response for a predetermined time, transmits the BLE signal of the advertising packet to a predetermined period.
