Detailed Description
Reference will now be made in detail to embodiments of the present application, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present application and should not be construed as limiting the present application.
Based on the above description of the background art, in order to improve the convenience of payment, NFC payment is increasingly popularized in mobile payment, however, for example, in the case that an NFC device (such as a mobile phone) is powered off or not networked, as long as a digital wallet of digital money at the central bank is on the device, a network is not required, or even no power is available, as long as the devices of both payees meet each other, a transfer function can be implemented, and the security of the transaction is relatively poor.
In order to solve the technical problems, the transaction processing conditions are determined according to the device state information, namely different transaction processing conditions are obtained based on different device state information, and the transaction processing request is processed in a targeted manner based on the transaction state information and the transaction processing conditions, so that different safety judgments are performed on different device state information of different NFC devices, such as a device on state, a device off state and the like, so as to process the transaction, and the safety of the transaction processing is improved.
A near field communication-based transaction processing method and apparatus according to an embodiment of the present application are described below with reference to the drawings.
Fig. 1 is a flowchart illustrating a transaction processing method based on near field communication according to an embodiment of the present application.
The conversation identification method can be applied to Near Field Communication (NFC) equipment. The NFC device may be any device having a computing capability and an NFC function, for example, a PC (Personal Computer), a mobile terminal, and the like, and the mobile terminal may be a hardware device having various operating systems, touch screens, and/or display screens, such as a mobile phone, a tablet Computer, a Personal digital assistant, and a wearable device.
As shown in fig. 1, the near field communication based transaction processing method may include the steps of:
In the embodiment of the present application, the NFC device includes an NFC unit and a security unit, and the NFC unit and the security unit are connected through a host control interface, and more specifically, the NFC unit and the security unit may be integrated through the host control interface, such as may be a chip.
In particular, the transaction processing request may be understood as triggering the transaction processing, and may be implemented in many ways, for example, by contacting the NFC device with another NFC-enabled device and triggering the NFC unit through the wireless transmission interface, that is, receiving the transaction processing request.
Further, after receiving the transaction processing request, the NFC unit obtains device state information of the NFC device, such as one or more of a device power-on state, a device power-off state, a device screen-on state, a device screen-off state, a device screen-lock state, and a device networking state.
In this embodiment of the application, there are many ways to obtain the device state information of the NFC device, and the setting may be selected according to an application scenario, for example, as follows:
in a first example, the NFC device further comprises: the NFC equipment comprises a power management unit and an equipment power management unit, wherein the power management unit is connected with the equipment power management unit, acquires a power signal of the equipment power management unit, and acquires an equipment power-on state or an equipment power-off state of the NFC equipment according to the power signal.
In a second example, the device state obtaining instruction is sent through a preset software protocol, so as to obtain a device power-on state or a device power-off state of the NFC device.
In a third example, the screen state obtaining instruction is sent through the NFC service to obtain one of a device screen opening state, a device screen extinguishing state, and a device screen locking state of the NFC device
In a fourth example, when the NFC device is in the powered on state, the networking state obtaining instruction is sent by the NFC service, so as to obtain the device networking state of the NFC device.
Further, the NFC unit obtains transaction state information such as one or more of a current transaction amount, identity information of both parties of the transaction, a historical transaction frequency, and a transaction amount within a preset time period.
Finally, the NFC unit sends the device state information and the transaction state information of the NFC device to the security unit through a preset interface protocol, such as a host control interface protocol.
And 102, the safety unit acquires a preset transaction processing condition corresponding to the equipment state information, judges whether the transaction state information meets the transaction processing condition, and processes the transaction processing request under the condition that the transaction processing condition is met.
In the embodiment of the application, after receiving the device state information and the transaction state information of the NFC device by the NFC unit through a preset interface protocol, such as a host control interface protocol, the security unit obtains a preset transaction processing condition corresponding to the device state information.
It can be understood that, in order to improve the security of transaction processing, different preset transaction processing conditions may be set for different device status information, for example, as follows:
in a first example, in a shutdown state of the device, a user cannot confirm payment through a fingerprint or a payment password in a normal startup state, and is easily stolen by malicious shutdown, so that corresponding preset transaction processing conditions may be set, such as maximum transaction amount, no more than a preset transaction time threshold within a preset time period, and the like.
In the second example, when the device is in the screen-off state or the screen-locking state, the user may be maliciously embezzled in the transaction under the unknown condition, so that the device can also adapt to the preset transaction processing conditions such as transaction amount, transaction times and transaction parties.
In a third example, the device networking state is an offline state, and the device cannot be networked for security authentication, but can perform transaction through fingerprint authentication, so that preset transaction processing conditions such as a higher transaction amount, transaction times and the like can be set.
Further, whether the transaction state information satisfies the transaction processing condition is determined, and the transaction processing request is processed under the condition that the transaction processing condition is satisfied, it can be understood that different transaction processing conditions are different in determining possible transaction processing results for the transaction state information, which is exemplified as follows:
in a first example, the transaction state information is obtained as the current transaction amount, the identity information of both parties of the transaction, the historical transaction frequency and the transaction amount within the preset time period, and whether the current transaction amount, the identity information of both parties of the transaction, the historical transaction frequency and the transaction amount within the preset time period meet the transaction processing conditions is judged.
In a second example, the transaction status information is obtained as the current transaction amount, and whether the current transaction amount satisfies the transaction processing condition is determined.
When the transaction processing condition is not satisfied, the transaction processing request is not processed, that is, the transaction processing request is rejected.
According to the transaction processing method based on the near field communication, by receiving a transaction processing request, the NFC unit acquires the equipment state information and the transaction state information of the NFC equipment and sends the equipment state information and the transaction state information to the safety unit through a preset interface protocol; the safety unit acquires preset transaction processing conditions corresponding to the equipment state information, judges whether the transaction state information meets the transaction processing conditions or not, and processes the transaction processing request under the condition that the transaction processing conditions are met. Therefore, the transaction processing conditions are determined according to the equipment state information, and the transaction processing request is processed in a targeted mode according to the transaction state information and the transaction processing conditions, so that the security of transaction processing is improved.
Based on the above embodiment, the present application sends the device state information (for example, state or action information such as device power-on, device normal power-off, device power-off without power, device networking, screen-off and screen-locking, etc.) to the security unit through the NFC unit.
It can be understood that the NFC unit may acquire the device state information through hardware or software, and acquire the state that may affect the secure payment through hardware or software, and provide the state to the security unit to perform the targeted subdivision processing on the security of the transaction, thereby ensuring the security of the transaction.
In a possible implementation manner of the embodiment of the present application, the device state information includes one or more of a device power-on state, a device power-off state, a device screen-on state, a device screen-off state, a device screen-lock state, and a device networking state.
Specifically, as shown in fig. 2, Display off/Lock, Switch on, Switch off (Power off, including normal Power off or no Power off), Battery off (Battery complete physical Power off), PMU (Power Management Unit), and VBAT are voltages.
Specifically, in the Display Off/Lock state, PMU Off is in the device Off state, VBAT is LOW, and Display On is in the device On state; in the Switch On state, pmuoff is in the device Off state, VBAT is in the LOW possibly Battery Off state, pmuon is in the device On state in the Switch Off state, and VBAT is in the HIG (high) state in the Battery Off state.
It should be noted that, when the device is powered off in a power-off state, the actual battery is not the true 0% of the electricity, but 20% to 30% of the standby electricity is still left, the voltage may reach, for example, 3.3V, the powers of the NFC unit and the security unit are very low, the remaining electricity of the NFC device still supplies power to the NFC unit normally, the NFC unit is sufficiently driven to complete communication with the security unit for many times, the security unit application completes or rejects a transaction, and the complete physical power-off state of the battery corresponds to the complete power-off state of the battery.
In a possible implementation manner of the embodiment of the present application, the NFC device further includes: the power management unit is connected with the equipment power management unit; acquiring a power supply signal of a device power supply management unit, and acquiring a device power-on state or a device power-off state of the NFC device according to the power supply signal; or, sending a device state acquisition instruction through a preset software protocol to acquire a device power-on state or a device power-off state of the NFC device.
Specifically, as shown in fig. 3, the device state information is acquired when the NFC transaction is performed: the NFC and eSE (i.e., NFC unit and secure unit) chips can acquire the device on/off state, the device off/screen lock state, and the networking state in two ways: hardware and software. The on-off state of the equipment and the screen-off and screen-locking state of the equipment can be transmitted through software and hardware at the same time, and the networking state can be transmitted only through the software.
Specifically, as shown in fig. 4, the Power Management unit (Integrated Power Management) is directly connected to the device Power Management unit (Mobile Power Management), and the device Power Management unit includes: battery module (Battery) and System power PMU unit (System PMU).
Specifically, the hardware physical power detection and detection circuit can realize equipment power detection according to a power signal of the mobile PMU to finish equipment shutdown detection; when the normal equipment is actively powered off, acquiring the on-off state of the equipment through a built-in NFC forum software protocol stack; when the device is abnormally shut down, the state is detected based on the hardware physical power supply.
In a possible implementation manner of the embodiment of the application, the screen state obtaining instruction is sent through the near field communication service to obtain one of a screen opening state, a screen closing state and a screen locking state of the NFC device, and the networking state obtaining instruction is sent through the near field communication service to obtain the device networking state of the NFC device when the NFC device is in the screen opening state.
Specifically, as shown in fig. 5, the NFC and the eSE (NFC unit and security unit) constitute a chip hardware layer, the HAL can be understood as a hardware driver layer, the Native can be understood as a software service packet layer, the Android is an operating system layer, and the top is various device application software used by daily users.
Specifically, the command for issuing the SCREEN STATE obtaining instruction based on the NFC service may be, for example, command SCREEN _ STATE _ CMD, and one of a SCREEN on STATE, a SCREEN off STATE, and a SCREEN locked STATE of the device (SCREEN is turned on, SCREEN is turned off, and SCREEN is locked) may be obtained.
Specifically, in the above embodiment, the device STATE obtaining instruction is sent through a preset software protocol to obtain the device POWER-on STATE or the device POWER-off STATE of the NFC device, for example, the device POWER-on/off STATE obtaining instruction issued through the device software end near field communication service may be, for example, the device POWER-on/off STATE obtaining instruction may be SCREEN _ STATE _ CMD/RSP, CORE _ SET _ POWER _ MODE _ CMD/RSP, and the device POWER-on/off STATE is obtained.
Specifically, in the power-off state, the device networking state cannot be acquired, and the networking state in the power-on state is acquired and issued to a chip composed of the NFC unit and the security unit through the NFC service networking state.
Based on the above embodiments, it can be understood that the security processing of the transaction is mainly performed in the security unit, the NFC unit is responsible for transmitting the device status information to the security unit, and the application built in the security unit is responsible for determining whether the status is a normal transaction condition, so as to process the transaction, for example, the user swipes the card through the RF Interface wireless transmission Interface to activate the NFC unit for processing, the NFC unit transmits the data to the security unit SE (secure element) through the host control Interface HCI Interface, and the payment applications (programs) pre-installed in the SE process the payment transaction. Besides the device status information, the security unit also needs to perform corresponding security processing according to other input information of the NFC unit, such as the amount of money.
For example, as shown in fig. 6, in a single chip integrated with an NFC unit and a security unit SE, the two units perform information transmission, such as transmission and reception of device state information (power on/off, screen off and screen lock) through a Host Controller Interface (HCI) Interface, and perform NFC security transaction security processing based on a device system, specifically, the NFC unit and the security unit perform state interaction, and after acquiring a state, the NFC unit sends a state message to the security unit through an HCI protocol; after the security unit acquires the state, marking the current state (equipment state information, transaction state information and the like); and the Applet in the safety unit acquires the current STATE in real time through an instruction such as PMU service GET _ PMU _ STATE _ CMD/RSP to complete the transaction processing.
The networking state is transmitted and received, and the NFC service networking state is acquired and is transmitted to the NFC unit and the safety unit; after the security unit acquires the state, marking the current state; and the Applet in the safety unit acquires the current STATE in real time through an instruction such as PMU service GET _ PMU _ STATE _ CMD/RSP to complete the transaction processing.
Specifically, the security unit processes the transaction, and after receiving the device state information, the transaction applets application built in the security unit further needs other input information of the NFC unit to perform corresponding processing, for example, the transaction amount can be processed according to the device state information (the device on/off state, the screen off/lock state, the device networking state), the transaction amount (large amount, small amount), the identity of both parties of the transaction (bus, bank, individual, etc.), the historical transaction frequency, and the accumulated daily transaction amount.
Further, after the information is acquired, for example, in an abnormal state, the transaction of the large amount is totally rejected, and only the transaction of the small amount is allowed; and the transaction processing flexibility can be further improved by performing more detailed processing according to the arrangement and combination of the conditions.
In one possible implementation manner of the embodiment of the application, a transaction processing condition adjustment request is received; wherein the transaction processing condition adjustment request includes device state information; and adjusting the preset transaction processing conditions corresponding to the equipment state information according to the transaction processing condition adjustment request.
It can be understood that the consideration factors can be set in advance by the user, such as setting the single transaction amount in advance by the user, and setting the transaction processing conditions such as the upper limit of daily transaction amount or refusing the transaction under the condition that some type of merchant is out of power.
Therefore, by the identification, transmission and transaction processing limiting operation of the equipment state information, normal transaction of an NFC payment user can be guaranteed under various conditions, malicious embezzlement can be prevented, the loss risk of the user is reduced, and the method is particularly suitable for payment application with safety requirements on double offline.
