detailed description

The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of this application.

With the development of Internet technology, electronic payments that do not need to rely on cash have become more and more popular payment methods. Generally, in electronic payment, the user needs to take out the electronic products used for payment to perform payment operations, such as taking out the mobile phone and calling up the payment QR code to scan, taking out the mobile phone to enter the scan code interface to scan the store receiving QR code, take Give the bank card to the cashier to swipe the card through the credit card machine. In these electronic payment processes, users need to take out electronic products for payment and perform corresponding operations, and the entire payment process is relatively time-consuming.

In order to increase the payment speed and shorten the payment time, payment can be made through the user's biometric information, such as the user's face, fingerprint, palmprint, and iris, which can uniquely identify the user's identity. When paying, the user can directly provide the corresponding biometric information in the biometric collection device provided by the merchant. For example, when paying by face, the user provides the face in front of the face collection device for the face collection device to collect, and the user does not need additional information Take out the mobile phone and other payment devices, the payment speed is faster and the operation is simpler.

However, there are certain security risks when paying through biometric information. On the one hand, although biometric information can uniquely identify a user’s identity, there is also a very small chance of identification errors, such as identifying one user’s biometric information as another user’s biometric information; on the other hand, criminals may pass The simulation imitates the biometric information of other users and impersonates other users for payment.

According to the characteristics of the user’s use of the mobile terminal and the characteristics of offline shopping, the inventor found that if it is determined that the user enters the vicinity of the payment device, and the user receives the biometric information provided by the payment device for deduction, it can be further determined The identity feature information provided for the user himself, thereby further ensuring the security of payment. Therefore, the inventor carefully studied the payment process through the user's biometric information.

The inventor found that in the case of payment via biometric information, the biometric information usually corresponds to a payment account. When the user's biometric information is obtained, the payment account corresponding to the biometric information is matched, and the payment account is deducted from the matched payment account. The payment account matched by the biometric information may be a payment account bound in the mobile terminal, such as an account of a certain payment application in the mobile terminal. When shopping offline, users usually carry a mobile terminal bound with a payment account. Therefore, in the case where it is determined that the mobile terminal bound with the payment account is located near the payment machine, the receiving user makes the payment through the payment machine, which can further ensure the security of the payment.

Therefore, the inventor proposes the payment method, device, system, mobile terminal, payment device, and server provided by the embodiment of the application. The payment method provided by the embodiment of the application allows the mobile terminal user to pass the payment device without operating the mobile terminal. Payment is completed by collecting biometric information, thereby improving payment efficiency and user experience in the payment process. In addition, the mobile terminal can directly obtain the device identification of the payment device from the broadcast data, thereby reducing the power consumption of the mobile terminal. Furthermore, when the payment server completes the payment, it will first verify the biometric information uploaded by the payment device. Whether the corresponding payment account has been bound with the device identification of the payment device, thereby improving the security of payment.

The following first introduces the payment system involved in the payment method and device provided in the embodiments of the present application.

Please refer to FIG. 1, the system involved in FIG. 1 includes a mobile terminal 100, a payment device 200 and a payment server 300. The mobile terminal 100 may be a mobile phone or a tablet computer, etc., and a payment account pre-bound by the user is stored in the mobile terminal. The payment device 200 is used to collect the user's biometric information and transmit it to the payment server 300, and the payment server 300 is used to complete the payment operation according to the received biometric information.

During the operation of the system, the payment device 200 may send broadcast data in a set wireless communication mode. The dotted circle around the payment device 200 in FIG. 1 represents the coverage of the broadcast data sent by the payment device. Optionally, the wireless communication mode includes a Bluetooth BLE mode or a Wi-Fi Aware mode. Correspondingly, the mobile terminal 100 can search for nearby wireless signals in the set wireless communication mode, so that when the mobile terminal 100 enters the range of the dashed circle shown in FIG. 1, it can receive the broadcast data sent by the payment device 200 .

As a way, after the mobile terminal 100 can receive the broadcast data sent by the payment device 200, the mobile terminal 100 can establish a wireless connection with the payment device 200 based on the currently adopted wireless communication mode, and then after the wireless connection is established, the mobile terminal 100 can obtain a device ID that uniquely identifies the payment device from the data stored in the payment device. As another way, in order to reduce the power consumption of the mobile terminal 100, the payment device 200 can carry its own device identification in the broadcast data sent by itself, so that the mobile terminal 100 may receive the broadcast data sent by the payment device 200. , The device identification of the payment device 200 that sends the broadcast data can be obtained from the broadcast data 200.

Optionally, after acquiring the device identification of the payment device 200, the mobile terminal 100 may send the acquired device identification and the stored payment account number to the payment server 300 through the base station 310 and the gateway 311 of the mobile communication network. Furthermore, the mobile terminal 100 may also send the acquired device identification and the payment account stored by itself to the payment server 300 through the wireless hotspot 320. When the payment server 300 receives the device identification and payment account number sent by the mobile terminal 100, it binds the device identification and the payment account number to indicate that the user of the payment account is near the payment device to which the device identification belongs. Furthermore, when the payment device 200 sends the collected biometric information to the payment server 300 during the payment process, the payment server 300 can verify that the payment account corresponding to the biometric information is bound to the device identification of the payment device, Complete the payment operation of the payment account.

Specifically, as shown in FIG. 2, because the mobile terminal 100 can obtain the device identification of the payment device 200 through the broadcast data sent by the payment device 200, so that the user does not need to operate the mobile terminal (for example, the mobile terminal in the figure can Always placed in the trouser pocket), the mobile terminal 100 can complete the binding operation of the payment account and the device identification of the payment device 200. In the payment process, the user only needs to collect the biometric information at the payment machine 200, and the payment machine 200 can send the collected biometric information to the payment server 300 to complete the payment, and the user does not need to operate the mobile terminal, thereby making During the whole process, users do not need to manually perform payment operations.

Based on the system and system operation process introduced above, the embodiments of the present application will be described in detail below with reference to the accompanying drawings.

Please refer to FIG. 3, a payment method provided by an embodiment of the present application is applied to a mobile terminal, and the method includes:

Step S110: The mobile terminal obtains the device identification of the payment device from the broadcast data sent by the payment device.

Among them, the payment device can send broadcast data based on Bluetooth BLE mode or Wi-Fi Aware mode. Taking the Bluetooth BLE mode as an example, the payment device can carry its own device identification in a specific field in the sent data packet during the process of sending broadcast data in the Bluetooth BLE mode. The format of a broadcast data packet is shown in the following table.

In the format of the data packet shown in the table above, the Length field is used to represent the length of the data packet, the field named Type represents the connection type of the current data packet, and the field named MFG ID represents the Bluetooth module sending the data packet The ID of the manufacturer, the field named iBeacon indicates that the current data packet is generated based on the iBeacon mode, and the field named MD5 indicates the device identification encrypted based on the MD5 method carried in the data packet. The field names Major, Minor and Ref are all Used to carry characteristic values to distinguish different data packets sent by the same device. Then it can be seen that in the data packet shown in the above table, the device identification of the payment device can be added in the 16Byte length field. It should be noted that the data packet format and the name of each field shown in the above table are only exemplary, and the data packet format and field names of the broadcast data sent by the payment device can also be changed according to the actual data carried.

Correspondingly, the mobile terminal can also scan the broadcast data based on the Bluetooth BLE mode or Wi-Fi Aware mode, so that after scanning the broadcast data sent by the payment machine, the mobile terminal can obtain the broadcast data from the scanned payment machine. The equipment identification of the payment machine. For example, if the mobile terminal scans broadcast data in Bluetooth BLE mode, after scanning the broadcast data that the payment device also sends in Bluetooth BLE mode, it can be parsed from the 16Byte length field of the broadcast data packet shown in the table above The equipment identification of the payment machine.

It should be noted that if the payment device sends broadcast data in Wi-Fi Aware mode, the payment device can also broadcast its own device identification in a similar manner. Accordingly, the mobile terminal can also use a similar method to obtain the device identification of the payment device .

In order to prevent the device identification of the payment device from being intercepted by other devices, as a way, the payment device can encrypt the device identification during the process of generating the broadcast data packet, so that even if other devices can obtain the broadcast data, What you get is the encrypted device ID.

If other illegal users crack the format of the broadcast data packet sent by the payment device, they can imitate the payment device to send the broadcast data through other illegal electronic devices that have access to the payment server. Within the coverage of the wireless signal, illegal electronic devices can still send the user's payment account number and the device identification of a certain payment machine to the payment server, thereby posing security risks to the user's payment account.

As a way to improve the above problems, the payment device can add a specific field to the data packet of the broadcast data in the process of generating broadcast data. The user stores a designated identifier. The designated identifier is used to identify whether the broadcast data is legal Payment equipment is sent. In this way, when the mobile terminal receives broadcast data, it recognizes whether there is a designated identifier in the received broadcast data; if it recognizes that there is a designated identifier in the received broadcast data, the received broadcast data is determined For the broadcast data sent by the payment machine, the device identification of the payment machine is obtained from the broadcast data sent by the payment machine.

Furthermore, the designated identifier can also be dynamically updated, thereby further improving the security of broadcast data. For example, the designated identification of each payment device can be stored in the payment server, and the stored designated identification of each payment device can be updated regularly, and when the payment server has a designated identification of a certain payment device After the identification is updated, the updated designated identification will be pushed to the corresponding payment machine so that the payment machine will write the updated designated identification into the generated broadcast data. Correspondingly, when the mobile terminal receives the broadcast data, it will send the parsed specified identifier to the payment server for verification. Only when the verification passed by the payment server is received, will the received broadcast data be included The device ID of the carried payment device is used as the device ID sent by the legal payment device.

It should be noted that in the two cases where the designated identifier included in the broadcast data can be fixedly configured and dynamically updated, as a way, the mobile terminal can determine the currently received identifier according to the format of the designated identifier that is parsed Whether the designated identifier in the broadcast data is fixedly configured or will be dynamically updated, and the subsequent verification method is determined according to the determined configuration of the designated identifier. For example, a fixedly configured designated identifier can be set to start with the character "G", and a dynamically configured designated identifier can be set to start with the character "D", and then the mobile terminal can be based on the designated identifier parsed from the broadcast data The first character to determine its configuration.

Specifically, when the mobile terminal determines that the designated identifier is a fixed configuration, it can directly verify whether the format of the designated identifier parsed by the mobile terminal meets the designated rules for verification, and when the mobile terminal determines the designated identifier In the case of dynamic configuration, the mobile terminal will send the specified identification to the payment server, so that the payment server can verify the specified identification according to the latest configuration. Then through the above method, even if the configuration of the designated identifier in the broadcast data sent by different payment devices is different, the mobile terminal can be flexibly adapted, thereby improving the compatibility between the mobile terminal and different payment devices. With capacity.

It is understandable that the working state of the CPU of the mobile terminal can have two modes: a sleep state and an awake state. In the sleep state, the CPU does not need to perform a large amount of data processing, so that the CPU can run in a low power consumption mode, thereby reducing the overall power consumption of the mobile terminal. Then in one case, the mobile terminal is in a dormant state before receiving the broadcast data sent by the payment device, and after receiving the broadcast data, it wakes up the CPU to the awake state to process the broadcast data packet. Then, in this case, as a way, the mobile terminal detects the working status of the CPU when it determines that the broadcast data carries the specified identifier. If it detects that the CPU of the mobile terminal is in the sleep state, the CPU in the sleep state is Switch to the awake state.

Step S120: Obtain the payment account bound to the mobile terminal.

It is understandable that after a user operates a mobile terminal to install or run an application with payment function, if he wants to pay through an application with payment function, he needs to log in on the application with payment function, and during the login process Then you need to enter the payment account number, and then after the user successfully completes the login in the application with the payment function, the mobile terminal will use the payment account that the user logs in as the payment account bound to the mobile terminal.

For the payment account bound to the mobile terminal, the application with payment function will be stored in a set storage area, and the mobile terminal can read the bound payment account from the set storage area. Among them, it should be noted that the designated storage area corresponding to some applications is private, and other other applications are inaccessible. In this case, if the mobile terminal needs to obtain the payment account corresponding to the application, Then the mobile terminal needs to call up the application first, trigger the application itself to obtain the payment account stored in the privately set storage area, and in this process, because the application is called, it will cause certain functions. Increase in consumption.

As a way, the mobile terminal can run a system service locally to process the step of obtaining a payment account. Specifically, the system service can send a broadcast message after it is started, so as to inform other applications in the mobile terminal that the corresponding account can be transmitted to the system service for storage. Then, after the application with the payment function receives the broadcast message, it can transmit the logged-in payment account to the system service through inter-process communication, so that the system service can be stored accordingly.

It is understandable that the system service can store the package name of each application and the account correspondingly in order to facilitate the distinction between accounts transferred from different applications. Furthermore, in this way, when the mobile terminal needs to obtain the bound payment account, it can directly run the aforementioned system service, and obtain the payment account from the storage area corresponding to the system service, so that it cannot be started without triggering the application. In the case of, the payment account bound to the application can be obtained, which reduces the overall power consumption of the mobile terminal.

In one approach, the payment device can support multiple payment platforms at the same time. In this way, the user can select a payment platform from multiple payment platforms supported by the payment device to complete the payment operation as needed. Specifically, as a method, after obtaining the device identification of the payment device, the mobile terminal may first query the payment platform supported by the payment device; in obtaining the payment platform supported by the payment device, the mobile terminal is bound to The payment platform of the past payment account is used as the target platform, and then the payment account corresponding to the target platform and the device identifier are respectively sent to the respective payment servers of the target platform.

Step S130: Send the device identification and the payment account number to the payment server, where the device identification is used by the payment server to receive the biometric information and the device identification sent by the payment machine, and detect the biometric feature The payment account corresponding to the information has been bound to the device identification of the payment device, and the payment operation of the payment account corresponding to the biometric information is completed.

It is understandable that if the mobile terminal has sent the device identification and payment account number obtained by the mobile terminal to the payment servers of multiple payment platforms, the payment server that finally performs the payment operation is the payment platform selected by the user during the payment process. The corresponding payment server.

In the payment method provided by the embodiment of the present application, in the case that the broadcast data carrying the device identification of the payment device is sent through the payment device, the mobile terminal obtains the device of the payment device from the broadcast data sent by the payment device After the identification, the mobile terminal sends the device identification and the payment account to the payment server in the payment account bound to the mobile terminal, so that the payment server receives the biometric information sent by the payment machine and Device identification, and detects that the payment account corresponding to the biometric information has been bound to the device identification of the payment device, and completes the payment operation of the payment account corresponding to the biometric information, thereby enabling the mobile terminal to The user does not need to operate the mobile terminal to complete the payment by collecting biometric information in the payment machine, thereby improving the payment efficiency and the user experience in the payment process. In addition, the mobile terminal can directly obtain the device identification of the payment device through broadcast data, thereby reducing the power consumption of the mobile terminal.

Please refer to Fig. 4, a payment method provided by an embodiment of the present application is applied to a payment machine, and the method includes:

Step S210: The payment device sends broadcast data carrying the device identification of the payment device, and the broadcast data is used by the mobile terminal to obtain the device identification of the payment device, and then associate the device identification with the mobile terminal The bound payment account is sent to the payment server.

Step S220: The payment machine sends a device identification and the collected biometric information to the payment server, where the device identification is used by the payment server to receive the biometric information and the device identification sent by the payment machine, and detect The payment account corresponding to the biometric information is bound to the device identification of the payment device, and the payment operation of the payment account corresponding to the biometric information is completed.

It is understandable that after responding to the payment instruction, the payment device starts to collect biometric information, and sends the device identification and the collected biometric information to the payment server. In this embodiment, the payment instruction can be triggered in multiple ways.

As a way, after the payment device detects the touch operation of the payment button configured on the touch area of the payment device, it starts to collect biometric information; after the biometric information is collected, it sends to the payment server Device identification and collected biometric information.

In this way, the user can touch the payment button in the touch area of the payment device after knowing the fee to be paid, thereby triggering the payment device to start collecting biometric information (for example, facial information or fingerprint information). Then, after the payment device collects the biometric information, it will send the collected biometric information and its own device identification to the payment server. After the payment server completes the payment operation, it can send a feedback message to the payment device to display it to the user for viewing. In addition, the payment server can also send a feedback message to the mobile terminal for the user to view.

The payment method provided by the embodiment of the present application allows the payment device to broadcast its own device identification, so that the mobile terminal can obtain the device identification of the payment device without establishing a connection with the payment device, thereby enabling the mobile terminal The user does not need to operate the mobile terminal to complete the payment by collecting biometric information in the payment machine, thereby improving the payment efficiency and the user experience in the payment process. In addition, the mobile terminal can directly obtain the device identification of the payment device through broadcast data, thereby reducing the power consumption of the mobile terminal.

Please refer to FIG. 5, a payment method provided by an embodiment of the present application is applied to a payment server, and the method includes:

Step S310: The payment server receives the payment account and the device identification of the payment machine sent by the mobile terminal, and binds the payment account and the device identification of the payment machine.

As a way, the payment server can establish a data table to store the device identification and payment account. Then, in this manner, the device identification and payment account number corresponding to the same data ID in the data table can be recognized by the payment server as the payment account number and the device identification of the payment device that are bound to each other.

For example, as shown in the following table:

IDID	Device_idDevice_id	User_idUser_id
11	G001G001	ZhangsanZhangsan
22	G002G002	LisiLisi

As shown in the above table, in this table, the field "ID" is used to uniquely identify data, the field "Device_id" represents the device identification, and the field "User_id" is used to represent the payment account. In this case, the IDs corresponding to the device identifier "G001" and the payment account "zhangshan" are both "1", and the mobile terminal can then be identified as the device identifier and payment account that are bound to each other.

Step S320: After receiving the biometric information sent by the payment machine and the device identification of the payment machine, the payment server searches for whether the payment account pre-bound with the biometric information matches the device identification of the payment machine. Binding.

In the case that the payment server stores the device ID and payment account that are bound to each other based on the data table, the payment server will first query the corresponding payment based on the biometric information after receiving the biometric information and the device ID sent by the payment machine And then check whether there is a payment account corresponding to the biometric information in the data table. If a payment account corresponding to the biometric information is found, it is determined that the payment account pre-bound with the biometric information and the payment account The device identification of the payment device has been bound.

Step S330: If bound, the payment server completes the payment operation of the payment account corresponding to the biometric information.

Step S340: If it is not bound, return a payment failure prompt message to the payment machine.

It should be noted that the payment server may only associate the storage device identification and the payment account within a certain period of time. For example, the payment server may use the time when the device identification and payment account number sent by the mobile terminal are received as the starting time, and start counting for a set time length. When it is detected that the set time period expires, the associated stored device identification and payment account are deleted. It is understandable that if the payment server repeatedly receives the same payment account to associate with the same payment device, the payment server will re-timing the set time length at the time of the most recent receipt.

The payment method provided by the embodiment of the application allows the payment server to perform the corresponding binding after obtaining the device identification and payment account number sent by the mobile terminal, so as to further obtain the biometric information sent by the payment machine and the payment After the device’s device identification, it can be determined that the payment account corresponding to the biometric information has been bound to the payment device before the subsequent payment operations will be completed, thereby improving the security of the payment, and during the payment process, mobile The terminal user does not need to operate the mobile terminal to complete the payment by collecting the biometric information in the payment machine, thereby improving the payment efficiency and the user experience in the payment process. In addition, the mobile terminal can directly obtain the device identification of the payment device from the broadcast data, thereby reducing the power consumption of the mobile terminal

Referring to FIG. 6, a payment method provided by an embodiment of the present application is applied to a payment system, the payment system includes a payment device and a mobile terminal, and the method includes:

Step S410: The payment device sends broadcast data carrying the device identification of the payment device.

Step S420: The mobile terminal obtains the device identification of the payment device from the broadcast data sent by the payment device.

Step S430: The mobile terminal obtains the bound payment account, and sends the device identifier and the payment account to the payment server.

Step S440: The payment machine sends the device identification and the collected biometric information to the payment server.

Step S450: After detecting that the payment account corresponding to the biometric information is bound to the device identifier of the payment device, the payment server completes the payment operation of the payment account corresponding to the biometric information.

As mentioned in the foregoing, in one approach, the payment device can support multiple payment platforms. The following will introduce in detail how the payment system operates in this case.

In this way, in addition to querying which payment platforms the payment device supports through the mobile terminal according to the device identification of the received payment device, the payment device can also directly add the payment platform it supports to the broadcast data for mobile After the terminal receives the broadcast data, it can directly analyze the payment platform that the payment device can support. Then obtain the payment platform supported by the payment machine, the payment platform of the payment account bound to the mobile terminal as the target platform; send the payment account corresponding to the target platform and the device identification to all The respective payment server of the target platform.

In one manner, in order to facilitate the mobile terminal to identify the payment platform supported by the payment machine, the platform of the payment account bound to the mobile terminal. The payment device can use the package name of the payment platform application installed on the mobile terminal as the identification of the payment platform. Therefore, after the mobile terminal obtains the platform supported by the payment device, that is to say, obtains the package name of the application corresponding to the supported payment platform, it can check whether there is a corresponding account in the stored payment account. If so, Then use the payment platform described in the corresponding payment account as the target platform.

Then in the case that the payment machine supports multiple payment platforms, in the payment process, the user can determine a payment platform to pay according to his needs. Then, the payment device sends the device identification and the collected biometric information to the payment server of the payment platform determined from the supported platforms.

As a way, as shown in Figure 7, in the case that the payment machine supports payment platform A and payment platform B, the payment trigger button 99 corresponding to payment platform A and the payment trigger corresponding to payment platform B can be displayed in the touch area. Button 98, if the user touches the payment trigger button 99, the payment device will send the collected biometric information and its own device identification to the payment server of the payment platform A, and if the user touches the payment trigger button 98, then the payment The machine will send the collected biometric information and its own device identification to the payment server of the payment platform B.

It is understandable that in the payment process, the payment operation can be completed smoothly only when the balance in the payment account is not less than the amount currently to be paid. In the process of facilitating QR code scanning and payment, the user is usually required to manually select the payment method corresponding to the payment account. The payment method includes payment with account balance or payment with a bank card bound to the payment account.

So in order to avoid the inconvenience to the user because the payment account of the payment platform selected by the user cannot complete the payment smoothly, as a way, in the payment process, the payment device can send it separately after collecting the user’s biometric information for the first time. Perform payment capability verification for the payment server of the payment platform that you support to verify whether the payment can be successfully completed through the payment account, so that only the payment trigger buttons of the verified payment platform are displayed in the touch area.

For example, if the payment platforms supported by the payment machine include payment platform A, payment platform B, and payment platform C. After the payment machine collects the user's facial information for the first time, it will first send the verification information to the payment server, so that the facial information can be sent to the payment server corresponding to the payment platform A, the payment platform B, and the payment platform C respectively. After the payment server receives the facial information, it will first verify the payment ability. For example, it can verify whether the current payment amount sent by the payment device along with the facial information is greater than the current balance. If it is greater, the payment server will pay The machine returns a verified message. Among them, as a method, the payment device may send verification information to the payment server once after detecting that the amount currently to be paid has increased.

Taking payment platform A as an example, if the payment server of payment platform A receives the verification information and obtains the facial information from the verification information, it can query whether the balance in the payment account corresponding to the facial information is greater than the current payment. The amount, or whether the payment account is bound with a bank card. If the payment server finds that the balance in the payment account of payment platform A is greater than the amount that needs to be paid, or the payment account is bound with a bank card, it will return a successful verification message to the payment machine, and the payment machine will display the payment in the touch area The payment trigger button corresponding to platform A. If the balance in the payment account of payment platform A is found to be less than the current amount to be paid, and the payment account is not bound with a bank card, then the verification failure message will be returned to the payment machine, so the payment machine will not display the payment The payment trigger button corresponding to platform A.

The method based on this embodiment can not only improve payment efficiency and user experience in the payment process. In addition, the mobile terminal can directly obtain the device identification of the payment device through the broadcast data, thereby reducing the power consumption of the mobile terminal. In the case that the payment device supports multiple payment platforms, only allowing the user to touch can be smooth The payment trigger button of the payment platform of the payment account that completes the payment prevents the user from choosing a payment account that cannot complete the payment without knowing which of the multiple payment accounts can complete the payment smoothly. As a result, the user needs to operate the mobile terminal to query the balance of the payment account, which in turn also improves the payment efficiency in the payment process and improves the user experience.
