The present disclosure relates to a data exchange technology, and in particular, to a user pairing method and apparatus, and a data exchange method, apparatus, and system based on the user pairing method.
Near field payment refers to that when a consumer purchases a commodity or service, payment to a vendor is performed by using a mobile phone instantly, payment processing is performed on site, and local communication with a vending machine and a point of sale (POS) machine is implemented offline by using a channel such as mobile phone radio frequency (NFC), infrared or Bluetooth.
In conventional near field payment, generally hardware of a mobile phone needs to be reconstructed or a hardware accessory needs to be added. Because of varied technical standards, it is very difficult to spread related hardware devices and payment solutions relying on such hardware devices in a short period of time. Under this background, innovative payment solutions where near field information is exchanged with the help of emerging technologies such as two-dimensional code (barcode) scanning, acoustic wave modulation, and mobile phone geographic location information, and then payment is completed by using a mature online payment technology are put forward one by one. These solutions are commonly characterized in that payment is performed in a near field, and does not depend on any special hardware device.
The technical principle of two-dimensional code (barcode) payment is that one party of a transaction compiles information into a two-dimensional or one-dimensional pattern according to different barcode standards, and the other party performs scanning by using a camera on a mobile phone and then restores from the pattern the information hidden in the pattern, thereby completing information exchange between both the parties of the transaction.
In acoustic wave payment, an essential microphone and earphone on a mobile phone are used. A transaction number or other key information related to a transaction is modulated through audio and then played by using a microphone on a mobile phone, and another mobile phone approaches the mobile phone that sends out the sound, records the sound by using an earphone, then may restore the information modulated into the sound by decoding the recorded sound, and then may perform payment according to the related information.
Payment based on geographic location information is typically “shake” payment. The current practice of the “shake” payment is that, when a user shakes a mobile phone, the mobile phone uploads its own geographic location information to a backend server; when finding that multiple persons shake mobile phones at a same location, the backend server recommends another person to the user, and the user may select a nearby person who is currently shaking a mobile phone to perform a transaction.
However, all the above solutions have some disadvantages. The two-dimensional code (barcode) payment depends on the widespread of two-dimensional code identifiers of commodities and construction of a barcode database, the acoustic wave payment requires a relatively quiet transaction site, the conventional “shake” payment is not intelligent enough that if multiple persons are all shaking mobile phones in a near field, a transaction object needs to be manually selected from multiple possible transaction objects, resulting in low efficiency and easy occurrence of errors.
In view of this, it is necessary to provide a user pairing method and apparatus, and a data exchange method, apparatus, and system, which can improve efficiency of user pairing and efficiency of subsequent data processing in a near field payment environment.

Embodiments of the present disclosure relate to a user pairing method, and a data exchange method, apparatus, and system between different electronic terminals.
In the example shown in
The memory 102 may be configured to store a software program and a module, such as a program instruction/module of a data exchange method in an embodiment of the present disclosure, and the processor 106 executes various function applications and data processing by running the software program and the module stored in the memory 102, that is, implement the data exchange method.
The memory 102 may include a high-speed random memory, and may further include a non-volatile memory, such as one or more magnetic storage apparatuses, a flash memory or another non-volatile solid-state memory. In some examples, the memory 102 may further include memories remotely disposed relative to the processor 106, and these remote memories may be connected to the electronic terminal 100 through a network. Examples of the network include, but are not limited to, the Internet, an enterprise intranet, a local area network, a mobile communications network, and a combination thereof. Access of the processor 106 and other possible components to the memory 102 may be performed under the control of the storage controller 104.
Various input/output apparatuses are coupled to the processor 106 through the peripheral interface 108. The processor 106 runs various software in the memory 102 to instruct the electronic terminal 100 to execute various functions and perform data processing. In some embodiments, the peripheral interface 108, the processor 106, and the storage controller 104 may be implemented in a single chip, and in some other examples, may each be implemented by an independent chip.
The network module 110 is programmed to receive/transmitting a network signal, and specifically, the network module 110 may be a network interface card, programmed to receive/transmitting a local area network signal; or may be a radio frequency module/WIFI module, programmed to receive/transmitting a mobile communications network signal or wireless local area network signal.
The touch screen 112 provides both an output interface and an input interface between the electronic terminal 100 and a user. Specifically, the touch screen 112 displays visualized outputs to the user, and content of these visualized outputs may include text, a pattern, a video, and any combination thereof. Some output results correspond to some user interface objects. The touch screen 112 further receives inputs of users, for example, gesture operations such as taps and slides of the users for a user interface object to respond to the inputs of these users. A technology for detecting an input of a user may be a resistive or capacitive touch detection technology or any other possible touch detection technologies. A specific example of a display unit of the touch screen 112 includes, but is not limited to, a liquid crystal display or light-emitting polymer display. It can be understood that, the touch screen is not essential. For example, an ordinary display screen may be further used, and the input apparatus may be replaced with a keyboard.
The accelerometer 114 is programmed to detect and outputting a current acceleration value of the electronic terminal 100, may generally detect the magnitude of an acceleration in each direction (generally triaxial directions), and may detect the magnitude and the direction of the gravity when the electronic terminal 100 is motionless.
The positioning module 116 is programmed to receive a positioning signal (for example, a Global Positioning System (GPS) signal) broadcasted by satellites, and calculating its own location according to the positioning signal. The location may be, for example, denoted by using a longitude, a latitude, and an altitude. Moreover, a manner of implementing positioning is not limited to using a GPS system. For example, other available satellite positioning systems further include the Beidou satellite positioning system (Compass Navigation Satellite System, CNSS) and a Global Navigation Satellite System (GLONASS). Moreover, positioning is not limited to using a satellite positioning technology. For example, a wireless positioning technology may be further used, such as a positioning technology based on a wireless base station or a wireless hotspot positioning technology. In this case, the positioning module 116 may be replaced with a corresponding module or is directly implemented by the processor 106 executing a specific positioning program.
The data exchange system of this embodiment is described below with reference to a second embodiment.
The second embodiment provides a data exchange method between electronic terminals.
Step S101: Each of a first electronic terminal and a second electronic terminal collects geographic location identification information and acceleration sample information, and sends the collected information to a server.
Step S102: The server determines, according to the geographic location identification information, whether a geographic location of the first electronic terminal and a geographic location of the second electronic terminal satisfy a predetermined condition.
Step S103: The server determines, according to an acceleration value and time corresponding to the acceleration value, whether the acceleration sample information of the first electronic terminal and the acceleration sample information of the second electronic terminal are matched.
Step S104: If the geographic location of the first electronic terminal and the geographic location of the second electronic terminal satisfy the predetermined condition and the acceleration sample information of the first electronic terminal and the acceleration sample information of the second electronic terminal are matched, send first to-be-exchanged data associated with the second electronic terminal to the first electronic terminal, and/or send second to-be-exchanged data associated with the first electronic terminal to the second electronic terminal.
The method is described in detail below with reference to
A same application may be installed in each of the first electronic terminal 101 and the second electronic terminal 103. In an example, the application has a face-to-face payment function. The face-to-face payment function has two aspects: face-to-face payment and face-to-face receipt. As shown in
After the user turns on the face-to-face payment or face-to-face receipt interface, Step S101 may be automatically executed in a backend. Certainly, this embodiment does not limit a triggering process of Step S101. For example, after the interface is turned on, only geographic location identification information is collected, while acceleration sample information is not collected temporarily. When a user input operation, such as a screen touch gesture, a press on a key in the interface or a space motion gesture, is detected, the geographic location identification information begins to be collected. For example, the first electronic terminal 101 and the second electronic terminal 103 are stacked together, and if they are shaken, a process of collecting acceleration sample information is triggered.
The geographic location identification information may, for example, include current geographic location information obtained by the positioning module 116. The current geographic location information may be denoted by using a longitude/latitude or another location identification code. The geographic location identification information may further be other information, such as an IP address, wireless local area network positioning information or mobile communications base station positioning information, which may be programmed to identify a geographic location. In order to distinguish different electronic terminals, the geographic location identification information should further include:
The acceleration sample information includes at least one sample, and each sample includes time and an acceleration value. The acceleration value may be detected by the accelerometer 114, and the time is time when the accelerometer 114 outputs/detects the acceleration value. Collected acceleration samples should satisfy a predetermined frequency or predetermined time, and for the collected samples, useless samples may be removed or merging processing is performed on several consecutive samples to generate a sample to be reported. After the acceleration sample information reaches a threshold of reporting the acceleration sample information in batches, the acceleration sample information may be uploaded to the server, and correspondingly, the server receives the geographic location identification information and the acceleration sample information sent by each of the first electronic terminal and the second electronic terminal.
It can be understood that, time in different electronic terminals may be different, and in order to unify comparison references, it is necessary to make time in acceleration sample information submitted by different electronic terminals be in a same standard. Therefore, referring to
After the clock calibration process, the first electronic terminal and the second electronic terminal may calculate a difference between a local clock and a server clock. Therefore, the time in the acceleration sample information may use a same time reference, for example, server time.
Referring to
In Step S102, at first, the geographic location of the first electronic terminal and the geographic location of the second electronic terminal are obtained according to the geographic location identification information of the first electronic terminal and the geographic location identification information of the second electronic terminal respectively. For example, if the geographic location identification information directly includes the geographic location, the geographic location obtained by parsing is directly used as the geographic location of the corresponding electronic terminal; if the geographic location identification information is an IP address, IP addresses may be directly compared, and similar IP addresses are determined to be at a same location; a corresponding geographic location may be further queried in a database of a mapping relationship between an IP address and a geographic location, and the obtained geographic location is used as the geographic location of the corresponding electronic terminal. Other types of geographic location identification information can be deduced by analogy, and are not described again herein.
After the geographic location of the first electronic terminal and the geographic location of the second electronic terminal are obtained, each of the geographic locations is mapped to two points in a same coordinate system, and then the distance between the first electronic terminal and the second electronic terminal may be learned by calculating the distance between the two points. It can be understood that, the distance between two points (x1, y1) and (x2, y2) in a same coordinate system is D=√{square root over ((x1−x2)2+(y1−y2)2)}.
Generally, the GPS civil positioning precision is about 5 meters at most, and is generally about 10 meters. Therefore, for positioning performed in a GPS manner, in Step S102, it is determined whether the geographic locations of the two terminals satisfy the predetermined condition, for example, whether the distance between the two terminals is less than a predetermined threshold. The threshold may be set to 10 meters. When a positioning manner with low precision, such as IP address positioning, is used, the threshold may be a precision range of the positioning manner.
In the process shown in
In an example, Step S103 includes the following steps: calculating a similarity between the acceleration sample information of the first electronic terminal and the acceleration sample information of the second electronic terminal according to the time and the acceleration value; and if the similarity exceeds a predetermined threshold, determining that the acceleration sample information of the first electronic terminal and the acceleration sample information of the second electronic terminal are matched. Persons of ordinary skill in the art may calculate the similarity between the two pieces of acceleration sample information by using any appropriate method. For example, records with a same time point in the two pieces of acceleration sample information are paired, and accordingly, an average value or a mean variance of differences between acceleration values in all records is calculated to represent the similarity. It can be understood that, the smaller the average value or mean variance of the differences is, the larger the similarity is.
The preset threshold of the similarity may be set according to a test result. For example, two electronic terminals are placed together to perform various gesture operations, acceleration sample information output by each of the two electronic terminals is recorded, and the similarity between the two pieces of acceleration sample information is calculated according to the method. Then the threshold may be set to a value slightly less than an average value of the test result.
In an example, Step S103 includes the following step: if the acceleration sample information of each of the first electronic terminal and the second electronic terminal includes at least two acceleration value inflection points with same time in a same time range, determining that the acceleration sample information of the first electronic terminal and the acceleration sample information of the second electronic terminal are matched.
It can be understood that, if the first electronic terminal 101 and the second electronic terminal 103 are touched consecutively multiple times in a time range, at a moment when each collision occurs, the acceleration thereof should be violently changed, and the acceleration value at the moment should be the value of an acceleration value inflection point in a nearby period of time. The quantity of electronic terminals whose acceleration values are compared may be limited to a fixed quantity range according to geographic locations. If electronic terminals in a fixed range consecutively have two acceleration value inflection points with same time, it can be determined that these two electronic terminals collide, and the two electronic terminals can be paired.
Further, in order to improve accuracy, on the basis of determining an acceleration value inflection point, time interval check may be added. That is, Step S103 includes the following step: if in a same time range, the acceleration sample information of each of the first electronic terminal and the second electronic terminal includes at least two acceleration value inflection points with same time, and time intervals between adjacent inflection points are the same, determining that the acceleration sample information of the first electronic terminal and the acceleration sample information of the second electronic terminal are matched. The principle of the time interval check lies in that, a time interval between two consecutive touch operations of different users is related to physical states thereof, and in the case of millisecond precision, each person should have a different time interval. On the basis of an acceleration value inflection point, a time interval may further precisely distinguish different users.
It can be understood that, the various manners all identify different user operations by using the acceleration sample mode. In addition to the examples listed above, persons of ordinary skill in the art may further distinguish different user operations by using any other acceleration sample modes.
The aforementioned application may separately log in to the server by using a first user account number and a second user account number. That is to say, the first electronic terminal is bound to the first user account number, and the second electronic terminal is bound to the second user account number. Therefore, the first to-be-exchanged data in Step S104 is also associated with the second user account number.
The first to-be-exchanged data may be any data, such as text, a number, a picture, a voice, a video, a document or the like. However, according to different application scenarios, the first to-be-exchanged data should be specific information at a place. For example, in the face-to-face payment scenario, the first to-be-exchanged data may include the receipt account number of a payee, a sum, related order information and so on. The receipt account number may be a bank account number or an account number of a third party payment system.
The first to-be-exchanged data may be pushed by the server 200 to the first electronic terminal 101, or may be stored in the server 200 and obtained by the first electronic terminal 101 in a polling manner.
Moreover, the first to-be-exchanged data may be uploaded by the second electronic terminal. For example, before Step S101, the interface in the second electronic terminal 103 is shown in
That is to say, the second electronic terminal 103 receives an input of a second user, generates the first to-be-exchanged data according to the input of the second user, and uploads the first to-be-exchanged data to the server. Therefore, the sum paid this time may be transmitted to the first electronic terminal 101.
However, relatively fixed information such as the receipt account number may be directly stored in the server, and may be found through an association by using the second user account number. When needed, the information may be directly obtained, and included in the first to-be-exchanged data.
The second to-be-exchanged data is substantially similar to the first to-be-exchanged data, and is not described again herein.
Further, after receiving the first to-be-exchanged data sent by the server, the first electronic terminal 101 may output the first to-be-exchanged data, receive data input by a first user, generate a data processing request according to the first to-be-exchanged data and the data input by the first user, and send the data processing request to the server.
Correspondingly, the server 200 invokes a public interface of a third party data processing system according to the data processing request; receives a processing result returned by the third party data processing system; and sends the processing result to the second electronic terminal 103. The server 200 may also perform the data processing process by itself, and directly send the processing result to the second electronic terminal 103.
In an example, the first to-be-exchanged data includes a payee account number and a sum. After the first electronic terminal 101 receives the first to-be-exchanged data, the payee account number and the sum are output in the interface shown in
After receiving the payment request, the server 200 performs parsing to obtain information such as the payer account number, the payee account number, the sum, the password and so on, and confirms whether the password input by the user is correct; and if correct, transfers a designated sum out from the payer account number and transfers the designated sum to the payee account number.
Further, the server 200 returns a data processing result to each of the first electronic terminal 101 and the second electronic terminal 103. Each of the first electronic terminal 101 and the second electronic terminal 103 may output a corresponding result. Therefore, the server 200 completes a data processing operation required for payment.
According to the data exchange method between electronic terminals provided in this embodiment, electronic terminals at a same place (or in a range) are obtained through sifting by using geographic locations, and then two electronic terminals which are currently contacting each other are decided by comparing modes of acceleration sample information collected by different electronic terminals in a same time range, so that data can be exchanged rapidly between the two electronic terminals, input operations of a user can be reduced, and efficiency of data exchange and data processing can be improved.
This embodiment provides a data exchange system. Referring to
A first electronic terminal 101 and a second electronic terminal 103 may send a clock synchronization request to the time service server 25 to calibrate a clock, and therefore it may be ensured that the clock reference of the first electronic terminal 101 is the same as that of the second electronic terminal 103.
After collecting geographic location identification information and acceleration sample information, each of the first electronic terminal 101 and the second electronic terminal 103 sends them to the exchange server 21.
The first electronic terminal 101 may further send, in addition to the geographic location identification information and the acceleration sample information, a data obtaining request to the exchange server 21.
The exchange server 21 forwards the geographic location identification information to the geographic location server 22, and forwards the acceleration sample information to the acceleration server 23.
According to the data obtaining request sent by the first electronic terminal 101, the exchange server 21 sends, to the geographic location server 22, a querying request, which is programmed to obtain all other electronic terminals in a predetermined range nearby the first electronic terminal 101.
Correspondingly, the geographic location server 22 calculates distances between different electronic terminals and the first electronic terminal 101, so as to obtain all other electronic terminals in the predetermined range nearby the first electronic terminal 101. Therefore, it can be understood that, all other electronic terminals described above should include the second electronic terminal 103. The geographic location server 22 returns all other matched electronic terminals to the exchange server 21.
The exchange server 21 sends a matching request to the acceleration server 23, where the matching request is programmed to request the acceleration server 23 to determine whether the acceleration sample information uploaded by the first electronic terminal 101 and acceleration sample information uploaded by all other electronic terminals described above are matched. For the specific matching rule, reference may be made to related description in the second embodiment, which is not repeated again herein. The acceleration server 23 returns a matching result to the exchange server 21.
The exchange server 21 may pair the first electronic terminal 101 and the second electronic terminal 103 according to the matching result returned by the acceleration server 23. The exchange server 21 may then send the first to-be-exchanged data associated with the second electronic terminal 103 to the first electronic terminal 101.
The first electronic terminal 101 outputs the first to-be-exchanged data, receives the data input by the user, generates a data processing request according to the data input by the user and the first to-be-exchanged data, and sends the data processing request to the exchange server 21.
The exchange server 21 completes data processing according to the data processing request. In an example, if the data processing request is a payment request, the exchange server 21 sends the payment request to the payment server 24. The payment request should include information such as a payee account number, a payer account number, and a sum.
In this embodiment, the geographic location identification information and the acceleration sample information are uploaded to the exchange server 21, and then forwarded by the exchange server 21 to the geographic location server 22 and the acceleration server 23. However, this embodiment is not limited to this manner. For example, the geographic location identification information and the acceleration sample information may be further directly uploaded by an electronic terminal to the geographic location server 22 and the acceleration server 23.
According to different demands, the architecture of this embodiment may be further changed. For example, the geographic location server 22 and the acceleration server 23 are merged into a same server.
According to the data exchange system of this embodiment, different functions are distributed in different servers, thereby helping to improve performance of the server.
This embodiment provides a user pairing method, which may be used in the server 200 shown in
Step S201: Receive geographic location identification information and acceleration sample information sent by each of a first electronic terminal and a second electronic terminal, where the acceleration sample information includes at least one sample, and each sample includes time and an acceleration value.
Step S202: Determine, according to the geographic location identification information, whether a geographic location of the first electronic terminal and a geographic location of the second electronic terminal satisfy a predetermined condition.
Step S203: Determine, according to the acceleration value and the time corresponding to the acceleration value, whether the acceleration sample information of the first electronic terminal and the acceleration sample information of the second electronic terminal are matched.
Step S204: If the geographic location of the first electronic terminal and the geographic location of the second electronic terminal satisfy the predetermined condition and the acceleration sample information of the first electronic terminal and the acceleration sample information of the second electronic terminal are matched, record a pairing relationship between a first user and a second user which are associated with the first electronic terminal and the second electronic terminal respectively.
It can be seen by comparing
The pairing relationship may be programmed to perform subsequent data processing, for example, establishing a group including the first user and the second user, performing data exchange between the first user and the second user to perform identity verification, creating a new game for the first user and the second user, and the like.
According to the user pairing method provided by this embodiment, electronic terminals at a same place (or in a range) are obtained through sifting by using geographic locations, and then two electronic terminals which are currently contacting each other are decided by comparing modes of acceleration sample information collected by different electronic terminals in a same time range, so that a pairing relationship between users associated with two electronic terminals may be rapidly established, and then subsequent data processing may be performed.
This embodiment provides a data exchange method between different electronic terminals, which is used in the server 200 shown in
Step S301: Receive geographic location identification information and acceleration sample information sent by each of a first electronic terminal and a second electronic terminal.
Step S302: Determine, according to the geographic location identification information, whether a geographic location of the first electronic terminal and a geographic location of the second electronic terminal satisfy a predetermined condition.
Step S303: Determine, according to an acceleration value and time corresponding to the acceleration value, whether the acceleration sample information of the first electronic terminal and the acceleration sample information of the second electronic terminal are matched.
Step S304: If the geographic location of the first electronic terminal and the geographic location of the second electronic terminal satisfy the predetermined condition and the acceleration sample information of the first electronic terminal and the acceleration sample information of the second electronic terminal are matched, send first to-be-exchanged data associated with the second electronic terminal to the first electronic terminal, and/or send second to-be-exchanged data associated with the first electronic terminal to the second electronic terminal.
According to the data exchange method between electronic terminals provided in this embodiment, electronic terminals at a same place (or in a range) are obtained through sifting by using geographic locations, and then two electronic terminals which are currently contacting each other are decided by comparing modes of acceleration sample information collected by different electronic terminals in a same time range, so that data can be exchanged rapidly between the two electronic terminals, input operations of a user can be reduced, and efficiency of data exchange and data processing can be improved.
This embodiment provides a data exchange method between different electronic terminals, which is used in the server 200 shown in
Step S401: Return server time according to a request of each of the first electronic terminal and the second electronic terminal, for the first electronic terminal and the second electronic terminal to calibrate time.
Each of the first electronic terminal 101 and the second electronic terminal 103 sends a clock synchronization request to the server; correspondingly, the server returns server time to the first electronic terminal 101 and the second electronic terminal 103 according to the clock synchronization request; each of the first electronic terminal 101 and the second electronic terminal 103 performs clock calibration according to the server time returned by the server. It can be understood that, in order to improve clock calibration precision, the process may be performed multiple times.
According to the data exchange method between electronic terminals provided in this embodiment, a clock calibration operation is further performed, so that time references of different electronic terminals may be consistent, which facilitates comparison of the acceleration sample information.
This embodiment provides a data exchange method between different electronic terminals, which is used in the server 200 shown in
Step S501: Receive the first to-be-exchanged data sent by the second electronic terminal.
Referring to
In the manner, the first to-be-exchanged data may be forwarded to the first electronic terminal 101, and therefore the input operations of the user in the first electronic terminal 101 may be reduced.
Moreover, the first to-be-exchanged data is not limited to being uploaded by the second electronic terminal 103. For example, the second electronic terminal 103 is bound to the second user, and the first to-be-exchanged data is found through an association according to the second user. For example, the receipt account number pre-stored by the second user in the server or the published commodity information may be directly read from the server, and the receipt account number and the commodity information are directly used as the first to-be-exchanged data.
According to the data exchange method between electronic terminals provided in this embodiment, the first to-be-exchanged data associated with the second electronic terminal may be conveniently forwarded to the first electronic terminal.
This embodiment provides a data exchange method between different electronic terminals, which is used in the server 200 shown in
Step S601: Receive a data processing request sent by the first electronic terminal.
After receiving the first to-be-exchanged data sent by the server, the first electronic terminal 101 may output the first to-be-exchanged data, receive data input by a first user, generate a data processing request according to the first to-be-exchanged data and the data input by the first user, and send the data processing request to the server. Correspondingly, the server 200 receives the data processing request sent by the first electronic terminal 101.
In an example, the first to-be-exchanged data includes a payee account number and a sum. After the first electronic terminal 101 receives the first to-be-exchanged data, the payee account number and the sum are output in the interface shown in
Step S602: Invoke a public interface of a third party data processing system according to the data processing request.
For example, a payment interface of a third party payment system is invoked, and payment data processing is performed according to the payment request.
Step S603: Receive a processing result returned by the third party data processing system.
After completing data processing, the third party data processing system returns a processing result to the server 200.
Step S604: Send the processing result to the second electronic terminal.
In this embodiment, a specific data processing operation is performed by the third party data processing system, but the server 200 may further perform a data processing operation, and directly send the processing result to the second electronic terminal 103.
In another aspect, the data processing result may be further sent to the first electronic terminal 101. Moreover, processing results of the first electronic terminal 101 and the second electronic terminal 103 may also be different.
According to the data exchange method between different electronic terminals in this embodiment, in addition to completing data exchange, a data processing operation may be further performed in the server to implement a specific data processing function, so that the user may trigger the data processing function in a very simple manner.
This embodiment provides a data exchange method between different electronic terminals, which is used in the server 200 shown in
Step S701: Calculate a similarity between the acceleration sample information of the first electronic terminal and the acceleration sample information of the second electronic terminal according to the time and the acceleration value.
Step S702: If the similarity exceeds a predetermined threshold, determine that the acceleration sample information of the first electronic terminal and the acceleration sample information of the second electronic terminal are matched.
Persons of ordinary skill in the art may calculate the similarity between the two pieces of acceleration sample information by using any appropriate method. For example, records with a same time point in the two pieces of acceleration sample information are paired, and accordingly, an average value or a mean variance of differences between acceleration values in all records is calculated to represent the similarity. It can be understood that, the smaller the average value or mean variance of the differences is, the larger the similarity is.
The preset threshold of the similarity may be set according to a test result. For example, two electronic terminals are placed together to perform various gesture operations, acceleration sample information output by each of the two electronic terminals is recorded, and the similarity between the two pieces of acceleration sample information is calculated according to the method. Then the threshold may be set to a value slightly less than an average value of the test result.
The method of this embodiment provides a method for determining whether two pieces of acceleration sample information are matched by calculating a similarity between acceleration samples.
This embodiment provides a data exchange method between different electronic terminals, which is used in the server 200 shown in
Step S801: Obtain an acceleration value inflection point according to the acceleration sample information of the first electronic terminal and the acceleration sample information of the second electronic terminal.
The acceleration value inflection point refers to a point whose acceleration value in the acceleration sample information is apparently different from a nearby acceleration value, for example, a point whose acceleration value suddenly becomes a negative value from zero or is suddenly reduced to a large extent.
Step S802: Determine whether there are two inflection points with a same time point; if yes, execute Step S803, or otherwise, determine that the two pieces of acceleration sample information are not matched.
Step S803: Determine whether time intervals between inflection points are the same; if yes, execute Step S804, or otherwise, determine that the two pieces of acceleration sample information are not matched.
It can be understood that, the sameness does not mean absolute sameness, and if a difference between two values falls in an allowable error range, it may be determined that the two values are the same. Moreover, the time measurement error depends on the allowable error range.
Step S804: Determine that the two pieces of acceleration sample information are matched.
It can be understood that, if the first electronic terminal 101 and the second electronic terminal 103 are touched consecutively multiple times in a time range, at a moment when each collision occurs, the acceleration thereof should be violently changed, and the acceleration value at the moment should be the value of an acceleration value inflection point in a nearby period of time. The quantity of electronic terminals whose acceleration values are compared may be limited to a fixed quantity range according to geographic locations. If electronic terminals in a fixed range consecutively have two acceleration value inflection points with same time, it can be determined that these two electronic terminals collide, and the two electronic terminals can be paired.
The principle of the time interval check lies in that, a time interval between two consecutive touch operations of different users is related to physical states thereof, and in the case of millisecond precision, each person should have a different time interval. On the basis of an acceleration value inflection point, a time interval may further precisely distinguish different users.
In this embodiment, Step S803 may be further omitted, that is, pairing between electronic terminals is performed only by using an acceleration inflection point value.
It can be understood that, the various manners all identify different user operations by using the acceleration sample mode. In addition to the examples listed above, persons of ordinary skill in the art may further distinguish different user operations by using any other acceleration sample modes.
According to the method of this embodiment, two electronic terminals may implement pairing at a server end only by consecutively touching each other several times with depending on a manner of two-dimensional code or acoustic wave, and a use manner is simple for a user, so that data exchange between different electronic terminals may be efficiently implemented.
This embodiment provides a data exchange method between different electronic terminals, which is used in the first electronic terminal 101 shown in
Step S901: Collect geographic location identification information and acceleration sample information of the first electronic terminal, and send the collected information to a server.
An application may be installed in the first electronic terminal 101. In an example, the application has a face-to-face payment function. The face-to-face payment function has two aspects: face-to-face payment and face-to-face receipt. As shown in
After the user turns on the face-to-face payment interface, Step S901 may be automatically executed in a backend. Certainly, this embodiment does not limit a triggering process of Step S901. For example, after the interface is turned on, only geographic location identification information is collected, while acceleration sample information is not collected temporarily. When a user input operation, such as a screen touch gesture, a press on a key in the interface or a space motion gesture, is detected, the geographic location identification information begins to be collected. For example, if the first electronic terminal 101 is shaken, a process of collecting the acceleration sample information is triggered.
Step S902: Receive first to-be-exchanged data returned by the server and associated with the second electronic terminal.
The data sent in Step S901 is used by the server for being matched with data sent by another electronic terminal, and if the first electronic terminal 101 and the second electronic terminal 103 are matched successfully, the server 200 may send the first to-be-exchanged data associated with the second electronic terminal to the first electronic terminal 101.
Step S903: Generate a data processing request according to the first to-be-exchanged data.
Referring to
Step S904: Send the data processing request to the server.
After receiving the data processing request, the server correspondingly performs data processing, and sends a processing result to the second electronic terminal 103.
According to the method of this embodiment, as long as the first electronic terminal 101 and the second electronic terminal 103 are shaken together or are touched consecutively, pairing between the first electronic terminal 101 and the second electronic terminal 103 is implemented in the server, without depending on a manner of two-dimensional code or acoustic wave, and a use manner is simple for a user, so that data exchange between different electronic terminals may be efficiently implemented.
