Detailed Description

With the continuous upgrade of internet services, the location information of the terminal has become one of the essential data in the payment security service. Currently, the common terminal positioning methods include a satellite positioning method (e.g., GPS positioning), a base station positioning method, and a router node positioning method. However, the router node location information is easily counterfeited, so that the location information of the terminal determined according to the location information is not reliable. In addition, the coverage of the satellite positioning information is limited, and the full-range coverage cannot be realized, for example, terminals in some underground shopping malls cannot receive GPS signals. In addition, the current positioning method of the base station estimates the position of the terminal through the position of the base station and the signal flight time from the terminal to the communication base station, requires two-way communication with the base station, and cannot ensure reliability.

However, the above terminal positioning methods are not applicable to the payment service with high requirements for the reliability of the terminal positioning information. In some application scenarios, lawbreakers implement cross-border payment behavior by counterfeiting positioning information of payment devices (e.g., shopping mall payment devices), resulting in cross-border payment risks.

In order to make the objects, technical solutions and advantages of the present disclosure more clear, the technical solutions of the present disclosure will be clearly and completely described below with reference to the specific embodiments of the present disclosure and the accompanying drawings. It is to be understood that the embodiments described are only a few embodiments of the present disclosure, and not all embodiments. All other embodiments, which can be derived by one of ordinary skill in the art from the embodiments given herein without making any creative effort, shall fall within the scope of the implementation of the present specification.

As used herein, the term "include" and its variants mean open-ended terms in the sense of "including, but not limited to. The term "based on" means "based at least in part on". The terms "one embodiment" and "an embodiment" mean "at least one embodiment". The term "another embodiment" means "at least one other embodiment". The terms "first," "second," and the like may refer to different or the same object. Other definitions, whether explicit or implicit, may be included below. The definition of a term is consistent throughout the specification unless the context clearly dictates otherwise.

Fig. 1 is a flowchart illustrating an example of a terminal area positioning method according to an embodiment of the present specification. Regarding the execution body of the embodiment of the method, it may be the first terminal having the payment function. It should be understood that the first terminal may be a dedicated payment device (e.g., a shopping mall payment device, a face brushing payment device, etc.), and the first terminal may also be a general-purpose device (e.g., a mobile phone, a tablet computer, etc.) having various other functions, which may be temporarily non-limiting.

As shown in fig. 1, in step 110, encryption area information broadcast by a prearranged wireless signal transmitter is acquired. Here, the encryption area information in the wireless transmitter may be used to reflect the location of the area where the wireless transmitting signal transmitter is located, for example, if the wireless transmitter is located in area a, the corresponding encryption area information is the encryption information of area a.

It should be noted that, for the operation of arranging the wireless signal transmitters, the corresponding wireless signal transmitters may be newly set or installed in the area, or authorization configuration may be performed for the existing wireless signal transmitters in the area, for example, configuration of corresponding encryption area information. The encryption area information may represent information generated by performing an encryption processing operation on the area information, and various encryption algorithms (for example, SM family encryption algorithm, etc.) may be used for the corresponding encryption algorithm, which may not be limited herein.

In some examples of embodiments of the present specification (e.g., in an ideal case), the encryption region information in the wireless signal may be exactly matched to the coverage of the wireless signal transmitter. Illustratively, when the wireless signal of the wireless signal transmitter i just covers city a, the encryption area information corresponding to city a may be configured in the wireless signal of the wireless signal transmitter i. Accordingly, the corresponding wireless signal transmitters may be arranged and/or shaped according to the size of the area to be differentiated by the service requirements, as will be developed in detail below.

In step 120, based on the acquired encryption area information, area information of the first terminal is determined. For example, the encrypted zone information may be decrypted (or requested to be decrypted) to obtain the corresponding terminal zone information.

In the embodiment of the specification, the encryption area information in the wireless signal of the wireless signal transmitter which is prearranged (for example, preauthorized) can be utilized to determine the area position where the terminal is located, and the terminal is difficult to counterfeit or tamper. In addition, the arrangement of the wireless signal transmitters can be established according to service requirements (for example, payment service requirements), is not limited by the coverage range of the satellite positioning signals, can ensure that the wireless signals can be comprehensively covered in the service area range, and can ensure that the service operation of the terminal can be safely and normally carried out.

Fig. 2 shows a flow chart of an example of a terminal area location method in a secure payment application scenario.

As shown in fig. 2, in step 210, a payment request is obtained. In one example of the embodiments of the present specification, the first terminal may acquire a user operation and generate a payment request when the user operation matches a preset operation (e.g., a click operation for a payment control). In another example of an embodiment of the present specification, the first terminal may receive a payment request from the second terminal, for example a mall payment device receiving a payment request from a user's cell phone.

In step 220, acquisition of encryption region information broadcast by a pre-arranged wireless signal transmitter is triggered based on the payment request.

In step 230, area information of the first terminal is determined based on the acquired encryption area information. For details and effects of the operations in step 220 and step 230, reference may be made to the descriptions of step 110 and step 120 in fig. 1, and further description is omitted here.

In step 240, the payment authority of the first terminal is acquired based on the zone information of the first terminal. Here, the payment authority may be opened only for some areas, for example, to prohibit cross-border payment using the first terminal.

In step 250, a payment operation corresponding to the acquired payment authority is performed. Illustratively, the first terminal may refuse the payment action or require further authentication operations when the obtained payment rights indicate that no payment rights are available, and may pass the payment action when the obtained payment rights indicate that payment rights are available.

In the embodiment of the present specification, the arrangement of the wireless signal transmitter may be formulated according to the payment service requirement, and is not limited to the coverage of the satellite positioning signal, so that the wireless signal can be fully covered in the area range of the payment service, and the payment operation of the first terminal can be safely and normally performed.

In some embodiments, a plurality of wireless signal transmitters may be respectively arranged in different areas in advance, and the wireless signal propagation manner and the wireless signal frequency of each wireless signal transmitter are respectively determined according to the size of the corresponding area. Here, diversified wireless signal propagation modes can be selected, and configuration can be performed according to service requirements or specific payment scenarios.

As described above, in some ideal cases, the encryption area information in the wireless signal may be exactly matched with the coverage area of the wireless signal transmitter, for example, the wireless signal broadcast by the wireless transmitter i in charge of the area a exactly covers the area a, the wireless signal broadcast by the wireless transmitter ii in charge of the area B exactly covers the area B, and there is no overlap between the area a and the area B.

It should be noted that the frequency of the wireless signal is about 10KHz to 3 × 10⁷KHz (or electromagnetic wave with a wavelength of 30000m to 10 μm), which is an electric wave signal generated by an alternating current of an oscillation circuit. In some examples, the wireless signals from the transmitting location to the receiving location may be divided into three propagation modes, namely sky wave, ground wave and space linear wave, and there are differences in propagation distances and characteristics corresponding to different propagation modes of the wireless signals.

The ground waves may represent electric waves propagating along the surface of the earth. In the process of radio wave propagation, the radio wave is absorbed by the ground, so that the propagation distance is short. The higher the frequency, the greater the ground absorption, so that short and ultra-short waves travel along the ground at a short distance, generally not more than 100km, while medium waves travel at a relatively long distance. The method has the advantages of less influence of weather, stable signal and high communication reliability.

Sky waves (also called ionospheric reflection waves) may represent radio waves that propagate by ionospheric reflection in the atmosphere. In the sky wave, the transmitted electric wave is reflected by an ionized layer which is 70-80 km above the ground and then reaches a receiving place, and the propagation distance is long, generally more than 1000 km. But the defects are that the influence of the weather of the ionized layer is large, and the transmission signal is unstable. The short wave frequency band is the best frequency band for sky wave propagation, and the short wave single side band radio station equipped for the fishery ship is the equipment for performing remote communication by using the sky wave propagation mode.

A spatial line wave (also called a line wave or a line-of-sight wave) may represent an electric wave that travels straight in space from a transmitting location to a receiving location. The propagation distance of the spatial linear wave is a visual range, and is only tens of kilometers. The interphone and the radar which are equipped in the fishery ship are both devices which communicate by utilizing a space wave propagation mode.

In the embodiment of the present specification, the wireless signal propagation manner and the wireless signal frequency of the wireless signal transmitter may be adjusted according to the control area range, and the lower the frequency, the longer the wavelength, the smaller the receiving range, for example, when it is necessary to distinguish the smaller region location information, the frequency may be agreed to perform adaptive adjustment on the wireless signal frequency. For example, ground waves may cover an area range within 100km, sky waves and spatial line waves may cover a larger area range.

As described above, in an ideal state where wireless signal transmitters are arranged, each wireless signal transmitter can fully cover an authorized area range, and there is no overlap in signal coverage between adjacent wireless signal transmitters. However, in some cases, when arranging wireless signal transmitters, signal coverage and signal overlap aspects may not be fully compromised, e.g., there may not be an overlapping region while achieving full coverage.

In view of this, fig. 3 shows a flowchart of an example of determining area information of a first terminal according to an embodiment of the present specification.

In step 310, it is determined whether a plurality of encryption area information broadcasted from a plurality of wireless signal transmitters respectively is acquired. In this way, it is possible to identify whether the first terminal is located in a signal overlapping position of the plurality of wireless signal transmitters.

When the judgment result in step 310 indicates that there are a plurality of encrypted area information, it jumps to step 321. When the judgment result in step 310 indicates that only one encryption area information exists, it jumps to step 323.

In step 321, the wireless signal strength corresponding to each of the acquired encryption area information is determined.

In step 330, the zone information of the first terminal is determined based on the acquired encryption zone information corresponding to the maximum wireless signal strength.

In addition, in step 323, area information of the first terminal is determined based on the acquired encryption area information.

In the embodiment of the present specification, for a first terminal located at a wireless signal overlapping position, encrypted area information corresponding to terminal area information is determined by wireless signal strength, so that it is possible to ensure accuracy of the determined area information while signals are fully covered.

In one example of the embodiments of the present specification, a decryption module (or a demodulation module) is configured on the first terminal, and a decryption algorithm preset in the decryption module is matched with an encryption algorithm corresponding to the encryption area information. In this way, the encrypted area information may be decrypted based on a preset decryption algorithm to determine the area information of the first terminal. Therefore, the first terminal can unlock the area information corresponding to the first terminal and execute corresponding payment operation according to the area information.

In another example of the embodiments of the present specification, only the server is configured with the decryption module, and the decryption module is not configured on the first terminal. In this way, the first terminal may send the encrypted area information to the server, so that the server performs decryption processing on the encrypted area information based on a preset decryption algorithm. Therefore, the safety of the determined area information can be ensured through remote decryption.

In some embodiments, the first terminal may also communicate with the server through the second terminal. Specifically, the first terminal may send the encryption area information to the second terminal, so that the second terminal sends the encryption area information to the server.

In the embodiment of the present specification, the first terminal (or, the payment device) only needs to receive signals, and does not need to feed back to the base station, so that the cost of the antenna and the modem device can be greatly reduced.

Fig. 4 is a flowchart illustrating an example of acquiring payment authority of a first terminal in a secure payment application scenario according to an embodiment of the present specification.

In step 410, it is determined whether the zone information of the first terminal belongs to a preset authorized zone set. Here, the authorization area set may be preset and stored in the first terminal according to the service requirement, and can meet the personalized requirements of various payment service application scenarios.

In step 420, the payment authority of the first terminal is determined according to the judgment result for the authorization area set. Illustratively, if it is determined that the zone information of the first terminal belongs to the authorized zone set, it is determined that the first terminal has the payment authority. Further, if it is determined that the zone information of the first terminal does not belong to the authorized zone set, it is determined that the first terminal does not have the payment authority.

In the embodiment of the specification, the authorization zone set is configured in each first terminal (for example, payment device), and the first terminal can locally determine the corresponding payment authority.

In some examples of embodiments of the present specification, the set of authorized regions may be configured in a server. Specifically, the first terminal may receive the payment authority of the first terminal from the server. Accordingly, the server may determine whether the region information of the first terminal belongs to a preset authorized region set, and determine the payment authority of the first terminal according to a determination result for the authorized region set. In one example of the embodiments of the present specification, the server may receive the region information from the first terminal, and determine the payment authority of the first terminal according to the region information. In another example of the embodiments of the present specification, the server may receive the encrypted area information from the first terminal, determine the area information of the first terminal through a decryption process, and determine the payment authority of the first terminal according to the determined area information.

Fig. 5 shows a signal interaction diagram of an example of a terminal region location method in a secure payment application scenario according to an embodiment of the present description.

As shown in fig. 5, in step 501, a first terminal 510 receives a payment request from a second terminal 520. Illustratively, the user performs a code scanning payment operation on the first terminal 510 (e.g., payment device) through the second terminal 520 (e.g., cell phone) to send a payment request.

In step 503, based on the payment request, the first terminal 510 is triggered to acquire the encryption area information broadcast by the wireless signal transmitter.

In step 505, the first terminal 510 sends the encryption area information to the second terminal 520.

In step 507, the second terminal 520 transmits the encrypted area information to the server 530.

In step 509, the server 530 performs decryption processing on the encrypted area information based on a preset decryption algorithm to determine the area information of the first terminal.

In step 511, the server 530 determines whether the region information of the first terminal belongs to a preset authorized region set, and determines the payment authority of the first terminal according to the determination result for the authorized region set.

In step 513, the server 530 sends the payment authority of the first terminal to the first terminal 510.

In step 515, the first terminal 510 performs a payment operation corresponding to the payment authority.

Alternatively, the server 530 may also send the payment authority of the first terminal to the second terminal 520 and forward the payment authority to the first terminal 510 via the second terminal 520.

In the embodiment of the specification, the wireless signal transmitters arranged in advance are utilized, and the payment operation is carried out under the condition that reliable regional information of the first terminal is obtained through communication interaction among the first terminal, the second terminal and the server, so that the safety of the payment operation can be guaranteed.

Fig. 6 shows a signal interaction diagram of an example of a terminal region location method in a secure payment application scenario according to an embodiment of the present description.

As shown in fig. 6, in step 601, a first terminal 610 receives a payment request from a second terminal 620. In some cases, the user may also operate the first terminal 610 (e.g., the user clicks a payment control on the first terminal 610) to cause a corresponding payment request to be generated at the first terminal 610.

In step 603, based on the payment request, the first terminal 610 is triggered to acquire the encryption area information broadcast by the wireless signal transmitter.

In step 605, the first terminal 610 performs a decryption process on the encrypted area information based on a preset decryption algorithm to determine the area information of the first terminal.

In step 607, the first terminal 610 determines the payment authority of the first terminal according to the region information of the first terminal and the preset authorized region set.

In step 609, the first terminal 610 performs a payment operation corresponding to the payment authority.

Through the embodiment of the specification, the first terminal 610 performs the payment operation under the condition of obtaining reliable region information by using the prearranged wireless signal transmitter, and the safety of the payment operation can be improved.

It should be noted that, for the example of the embodiment described in fig. 5 and fig. 6, in some application scenarios, some operations therein may be combined or replaced with each other, for example, in the example of the embodiment in fig. 5, the first terminal may locally decrypt and send corresponding area information to the second terminal.

In one example of the embodiments of the present specification, for the placement operation of the wireless signal transmitter, authorization configuration may be performed for the wireless signal transmitter existing in the area, for example, configuration of corresponding encryption area information. As an example of a specific placement process, geographical location information of each wireless signal transmitter, such as country-province-city, may be obtained, and the frequency and propagation manner of the wireless signal transmitter may be adjusted according to the signal coverage area of the service requirement. In the embodiments of the present specification, a low frequency signal such as a radio wave clock may be employed, and although the low frequency signal carries data to a limited extent, it suffices as long as the requirement for transmitting the encryption area information can be satisfied.

As described above with reference to fig. 1 to 7, embodiments of the terminal area positioning method and apparatus according to the embodiments of the present specification are described. The details mentioned in the above description of the method embodiments also apply to the embodiments of the apparatus of the present description. The above terminal area positioning device may be implemented by hardware, or may be implemented by software, or a combination of hardware and software.

In the 90 s of the 20 th century, improvements in a technology could clearly distinguish between improvements in hardware (e.g., improvements in circuit structures such as diodes, transistors, switches, etc.) and improvements in software (improvements in process flow). However, as technology advances, many of today's process flow improvements have been seen as direct improvements in hardware circuit architecture. Designers almost always obtain the corresponding hardware circuit structure by programming an improved method flow into the hardware circuit. Thus, it cannot be said that an improvement in the process flow cannot be realized by hardware physical modules. For example, a Programmable Logic Device (PLD), such as a Field Programmable Gate Array (FPGA), is an integrated circuit whose Logic functions are determined by programming the Device by a user. A digital system is "integrated" on a PLD by the designer's own programming without requiring the chip manufacturer to design and fabricate application-specific integrated circuit chips. Furthermore, nowadays, instead of manually making an Integrated Circuit chip, such Programming is often implemented by "logic compiler" software, which is similar to a software compiler used in program development and writing, but the original code before compiling is also written by a specific Programming Language, which is called Hardware Description Language (HDL), and HDL is not only one but many, such as abel (advanced Boolean Expression Language), ahdl (alternate Hardware Description Language), traffic, pl (core universal Programming Language), HDCal (jhdware Description Language), lang, Lola, HDL, laspam, hardward Description Language (vhr Description Language), vhal (Hardware Description Language), and vhigh-Language, which are currently used in most common. It will also be apparent to those skilled in the art that hardware circuitry that implements the logical method flows can be readily obtained by merely slightly programming the method flows into an integrated circuit using the hardware description languages described above.

The controller may be implemented in any suitable manner, for example, the controller may take the form of, for example, a microprocessor or processor and a computer-readable medium storing computer-readable program code (e.g., software or firmware) executable by the (micro) processor, logic gates, switches, an Application Specific Integrated Circuit (ASIC), a programmable logic controller, and an embedded microcontroller, examples of which include, but are not limited to, the following microcontrollers: ARC 625D, Atmel AT91SAM, Microchip PIC18F26K20, and Silicone Labs C8051F320, the memory controller may also be implemented as part of the control logic for the memory. Those skilled in the art will also appreciate that, in addition to implementing the controller as pure computer readable program code, the same functionality can be implemented by logically programming method steps such that the controller is in the form of logic gates, switches, application specific integrated circuits, programmable logic controllers, embedded microcontrollers and the like. Such a controller may thus be considered a hardware component, and the means included therein for performing the various functions may also be considered as a structure within the hardware component. Or even means for performing the functions may be regarded as being both a software module for performing the method and a structure within a hardware component.

The systems, devices, modules or units illustrated in the above embodiments may be implemented by a computer chip or an entity, or by a product with certain functions. One typical implementation device is a computer. In particular, the computer may be, for example, a personal computer, a laptop computer, a cellular telephone, a camera phone, a smartphone, a personal digital assistant, a media player, a navigation device, an email device, a game console, a tablet computer, a wearable device, or a combination of any of these devices.

For convenience of description, the above devices are described as being divided into various units by function, and are described separately. Of course, the functions of the various elements may be implemented in the same one or more software and/or hardware implementations of the present description.

As will be appreciated by one skilled in the art, embodiments of the present description may be provided as a method, system, or computer program product. Accordingly, the description may take the form of an entirely hardware embodiment, an entirely software embodiment or an embodiment combining software and hardware aspects. Furthermore, embodiments of the present description may take the form of a computer program product embodied on one or more computer-usable storage media (including, but not limited to, disk storage, CD-ROM, optical storage, and so forth) having computer-usable program code embodied therein.

The description has been presented with reference to flowchart illustrations and/or block diagrams of methods, apparatus (systems), and computer program products according to embodiments of the description. It will be understood that each flow and/or block of the flow diagrams and/or block diagrams, and combinations of flows and/or blocks in the flow diagrams and/or block diagrams, can be implemented by computer program instructions. These computer program instructions may be provided to a processor of a general purpose computer, special purpose computer, embedded processor, or other programmable data processing apparatus to produce a machine, such that the instructions, which execute via the processor of the computer or other programmable data processing apparatus, create means for implementing the functions specified in the flowchart flow or flows and/or block diagram block or blocks.

These computer program instructions may also be loaded onto a computer or other programmable data processing apparatus to cause a series of operational steps to be performed on the computer or other programmable apparatus to produce a computer implemented process such that the instructions which execute on the computer or other programmable apparatus provide steps for implementing the functions specified in the flowchart flow or flows and/or block diagram block or blocks.
