Description

Method and system for determining target client, client and server

Technical Field

The present application relates to the field of user login technologies, and in particular, to a method and a system for determining a target client, a client, and a server.

Background

Generally, when a user logs in a website or software at a client, the user can input an account and a password at a login interface. However, in recent years, with rapid development of network technologies, network security risks are increasing, and the probability that a user suffers from network security accidents such as account theft is increased by inputting an account and a password in a login manner. Therefore, in order to improve the security of the user login mode, many websites or software push mobile phone authentication login, for example, when a user sends a login request in a website or application of a PC, a background service server of the website or software sends an authentication code to a mobile phone of the user, and the user can complete login after inputting the authentication code received by the mobile phone in the website or software of the PC.

The login mode through inputting the verification code not only needs the user to manually input the account and the password, but also needs to read and input the verification code, the login process is complex, and the user experience degree is low. In the prior art, in order to reduce the complexity of user login, a two-dimensional code scanning mobile phone verification login method is provided. In the login process of two-dimension code scanning, a user opens a login webpage or application at a PC (personal computer) end, and the webpage or application interface displays the two-dimension code and prompts the user to scan the two-dimension code. The user opens the mobile phone and the corresponding application program, clicks a two-dimension code scanning button of the application program and starts a mobile phone camera, the two-dimension code displayed in the webpage or the application interface is scanned and the login of the PC terminal is authorized, and the background server receives the login authorization sent by the mobile phone of the user and allows the user to log in the webpage or the application of the PC terminal. Through the process of two-dimensional code scanning login, the user at least needs to open the mobile phone application program and start the corresponding application program and other operations, the login process is still complicated, and the user experience is not high enough.

Therefore, in the prior art, the user login method based on the mobile phone authentication is complex and complicated in operation process and low in user experience.

Detailed Description

In order to make those skilled in the art better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

The method for determining a target client according to the present application is described in detail below with reference to the accompanying drawings. Fig. 1 is a schematic method flow diagram of an embodiment of a method for determining a target client provided in the present application. Although the present application provides method steps as shown in the following examples or figures, more or fewer steps may be included in the method based on conventional or non-inventive efforts. In the case of steps where no necessary causal relationship exists logically, the order of execution of the steps is not limited to that provided by the embodiments of the present application. The method can be executed sequentially or in parallel (for example, in the context of a parallel processor or a multi-thread process) according to the method shown in the embodiment or the figures when the user logs in or the system executes in practice.

Specifically, an embodiment of the method for determining a target client provided by the present application is shown in fig. 1, where the method may include:

s1: and responding to a login request sent by the first client, and generating a first identifier according to a preset rule.

In this embodiment, the server may receive a login request sent by the first client, and generate the first identifier according to a preset rule in response to the login request sent by the first client. The server may include a hardware device having a data information processing function and necessary software required to drive the hardware device to operate, and the server may analyze the received login request to determine a target client. The server may provide a predetermined port through which a login request provided by a first client may be received. For example, the server may perform network data interaction with the first client based on a network protocol such as HTTP, TCP/IP or FTP and a network communication module.

In this embodiment, the first client may be a terminal device capable of accessing a communication network based on a network protocol. Specifically, for example, the first client may be a mobile smart phone, a computer (including a laptop computer and a desktop computer), a tablet electronic device, a Personal Digital Assistant (PDA), or a smart wearable device. In addition, the first client may also be software running on any of the above listed devices, such as a pay bank client, a mobile phone tab client, and the like, and the first client may also be a website having a user management function.

In this embodiment, when the user of the first client wants to log in at another client, a login request may be generated in the first client. The first client may be software with user management functions, such as WeChat, Taobao, QQ, etc. In a specific embodiment, for example, the first client is a mobile payment client, and when a user of the first client needs to log in at a web page of a notebook computer for payment, a PC-side login request can be initiated in the mobile payment client, and the PC-side login request can be the login request.

In this embodiment, after the first client terminal generates the login request, the login request may be sent to the server. In a specific embodiment, for example, the server may be a background service server of the payment client, and the background service server may store data associated with the payment client, and may further perform data transmission and instruction interaction with the payment client.

In an embodiment of the present application, the login request sent by the first client may include account information of the first client. The user account information may be a character string preset by the user of the first client or preset by the first client for the user. For example, the account information may be a user's pay account or a wechat account.

Of course, in another embodiment of the present application, the login request sent by the first client may not include the user account information of the first client, and the login request may be only a field written according to a preset format, where information such as the type of the request and the source IP address of the request initiator may be indicated in the field.

In this embodiment, after receiving the login request, the server may respond to the login request and generate the first identifier according to a preset rule.

In an embodiment of the present application, the first identifier may be a character string calculated by the server according to the user account information and the date and time of the current time according to a preset algorithm. The character string may be coded by decimal numbers such as 496729, binary numbers such as 011011, or a combination of numbers and letters such as 26e8T6, for example. In this embodiment, the first identifier may further have timeliness, where the timeliness refers to: after a preset time length from the moment of generating the first identifier, the first identifier loses effectiveness and cannot be recognized by a server or a client. For example, after a first identifier such as 496729 is generated, the first identifier has a validity time of 2 minutes, and then the first identifier will fail after 2 minutes. When the failed first identifier is provided to the server or the client, the failed first identifier cannot be recognized by the server or the client, so that subsequent user login operation cannot be performed according to the first identifier.

In this embodiment, a character string including the user account information and the current time date and time may be obtained, where the character string may be "qaanqian 20160508155825", where "qaanqian" may be the user account, "20160508" may be the current time date, and "155825" may indicate that the current time is 58 minutes and 25 seconds at 3 pm. In an embodiment of the application, the preset rule may include a hash algorithm, and the hash algorithm may convert the character string into a hash value, and use the hash value obtained through conversion as the first identifier.

In this embodiment, a first identifier may be generated according to a preset rule in response to the login request, and the first identifier may be used as a unique identifier of the login request of this time, so as to provide a data source for subsequent sound wave encoding.

S2: sending the first identifier to the first client, the first identifier being associated with the login request.

In this embodiment, since the first identifier is generated in response to a login request sent by the first client, the server may associate the first identifier with the login request. In this way, in the user login process of this time, within the valid time limit of the first identifier, the first identifier may be used as a password or a credential for user login. And the client sides of the two parties for user login can realize the authorization of user login through the first identifier.

In this embodiment, the server may store the first identifier and the login request in an associated manner through a data table, one column in the data table may store the first identifier, another column may store the login request, and the associated first identifier and the login request may be in the same row. Of course, the way of associating the first identifier with the login request is not limited to the above example, and other modifications are possible for those skilled in the art in light of the technical spirit of the present application, and all that can be achieved is covered by the scope of the present application as long as the achieved functions and effects are the same as or similar to the present application.

In this embodiment, after associating the first identifier with the login request, the server may send the first identifier to the first client. Specifically, the server may send the first identifier to the first client through a predetermined port.

In this embodiment, after receiving the first identifier, the first client may read characters included in the first identifier, and perform sound wave encoding on each character in the first identifier according to a provided relationship set between the characters and sound wave characteristic values (for example, sound wave frequencies). For example, the characters may include numerals 0 to 9 and subtitles a to f, and the correspondence between the characters and the sound wave frequency may be as shown in table 1.

TABLE 1 correspondence between characters and acoustic frequencies

Character(s)	Sonic frequency/kHz
		0	18
1	18.2
		2	18.4
…	…
		f	21

In this way, the first client may send the sound wave corresponding to the first identifier to the second client in a sound wave coding manner. In this embodiment, the second client may be a terminal device capable of accessing a communication network based on a network protocol. Specifically, for example, the second client may be a mobile smart phone, a computer (including a laptop computer and a desktop computer), a tablet electronic device, a Personal Digital Assistant (PDA), or a smart wearable device. In addition, the second client may be software with a user management function, such as WeChat, Paibao, Jingdong, and the like, and the second client may also be a website with a user management function, such as WeChat, Paibao official website, and the like. In one embodiment, for example, the second client may log in to a web page for a pay pal on a laptop computer. In the sound wave receiving process, generally, the sound wave receiving device of the device where the second client is located, such as a microphone, an external microphone, and the like, needs to be opened. It should be noted that, in an actual application scenario, there may be a plurality of second clients around the first client, and when the first client sends a sound wave signal through a speaker of the terminal device, at least one second client around the first client may receive the sound wave signal through a sound wave receiving device. In particular, when a first client needs to send a first identification of 8a67 to at least one second client, four segments of sound waves of different frequencies will be generated. The first client may sequentially send the four sound waves with different frequencies according to an order from left to right of the characters in the first identifier. In this embodiment, the first client may set the duration of each sound wave, which may be 100ms, for example, so that when the first client transmits the sound waves in sequence, the first identifier 8a67 will correspond to the sound wave band of 400 ms.

When the first client and the second client are both still, the second client may analyze the sound wave after receiving the sound wave, recognize the frequencies corresponding to the four sound waves, and then decode the four sound waves into the first identifier 8a67 according to the correspondence between the sound wave frequencies and the characters. However, in a practical application scenario, the number of the second clients may be more than one, and each second client may receive the four sound waves transmitted by the first client and may decode to obtain the first identifier. In this case, if each second client obtains the user login authorization from the server through the first identifier, the leakage of the personal information of the user is caused.

In view of the above, in this embodiment, the first client may generate relative motion with the second client, and according to the doppler effect, when the sound wave source and the sound wave receiving object generate relative motion, the frequency of the sound wave received by the sound wave receiving object may increase; when the sound wave source and the sound wave receiving object move away from each other, the frequency of the sound wave received by the sound wave receiving object decreases. The frequency value increase or decrease of the sound wave generated by the doppler effect may be referred to as a doppler frequency offset value (denoted as Δ f), and the doppler frequency offset value and the speed of the relative motion of the sound wave source and the sound wave receiving object may have a positive correlation, specifically, the positive correlation may be as follows:

wherein v is a relative movement speed between the sound wave source and the sound wave receiving object, λ is a sound wave wavelength, and θ is an included angle between a connecting line direction between the sound wave source and the sound wave receiving object and a relative movement direction between the sound wave source and the sound wave receiving object. The value of the frequency of the acoustic wave finally received by the acoustic wave receiving object can be obtained from the frequency value of the acoustic wave generated by the acoustic wave source and the doppler frequency offset value. Taking the example that the sound wave source and the sound wave receiving object move in opposite directions, the frequency of the sound wave finally received by the sound wave receiving object can be obtained by adding the value of the frequency of the sound wave generated by the sound wave source and the doppler frequency offset value. In this embodiment, the source of the sound wave of the at least one second client may be the first client. Therefore, in the process of transmitting the sound wave to the at least one second client by the first client, if relative motion occurs between the first client and the at least one second client, the frequency of the sound wave received by the at least one second client may increase due to the doppler effect. In an actual application scenario, the relative operation between the first client and the second client may be, for example: the first user holds the terminal device and swings towards the second client, relative motion can be generated between the two terminal devices, values of the included angles are different along with different positions between the second client and the first client, and accordingly Doppler frequency offset values generated due to the relative motion between the first client and the second client can be different, and different second clients can be identified according to the different Doppler frequency offset values.

In this embodiment, after the at least one second client receives the sound wave with frequency offset, the received sound wave may also be decoded. In a practical application scenario, a relative movement direction between the first client and the second client may be predefined, for example, a movement direction of the first client towards the second client may be predefined. Therefore, the frequency value of the sound wave received by the second client is higher than that of the sound wave sent by the first client. In this case, after the second client receives the sound wave with frequency offset, the sound wave frequency value with frequency offset may be compared with the original sound wave frequency value, so as to determine the original sound wave frequency value matching with the sound wave frequency value after frequency offset, and then the characters corresponding to the sound wave may be queried according to the determined original sound wave frequency value through the relationship table shown in table 1.

In this embodiment, the first identifier may be associated with the login request and sent to the first client, so that the clients of both parties performing user login may realize authorization of user login through the first identifier.

S3: and receiving a login request sent by at least one second client, wherein the login request sent by the second client comprises a second identifier and a sound wave characteristic value.

In this embodiment, when at least one second client receives the sound wave sent by the first client, the sound wave characteristic value corresponding to the sound wave may be identified, and the corresponding first identifier may be obtained by decoding according to the sound wave characteristic value. Then, the at least one second client may send the decoded first identifier and the frequency value of the sound wave to the server. It should be noted that, in an actual application scenario, in order to ensure security of data transmission between the client and the server, the first identifier sent from the second client may be encrypted by a preset encryption rule, so that the first identifier is converted into another character string. In this embodiment, the encryption rule may be, for example, DES3 algorithm or AES algorithm. In this embodiment, a character string obtained by encrypting the first identifier may be referred to as a second identifier. Then, after generating the second identity, the at least one second client may send a login request to the server. The second identifier and a characteristic value of a sound wave may be included in the login request. The sound wave characteristic value may be obtained by the second client through identification according to the received sound wave, and the sound wave characteristic value may include a frequency value of the sound wave, for example, the frequency value of the sound wave may be a frequency value after doppler frequency offset occurs. For example, the frequency values sent by the first client are 18kHz, 19kHz and 19.4kHz, and since relative motion occurs between the first client and the second client, the second client can obtain three frequency values with frequency offset, namely 18.12kHz, 19.12kHz and 19.52kHz, after recognizing according to the received sound wave signal. The second client may send the three frequency values at which the frequency offset occurred to the server.

In this embodiment, the frequency value of the sound wave may also be a doppler frequency offset value, that is, a difference value between the frequency value after the frequency offset occurs and the original frequency value. Specifically, assuming that the frequency values sent by the first client are 18kHz, 19kHz and 19.4kHz, since the first client and the second client perform relative motion, the second client can obtain three frequency values of frequency offset, namely 18.12kHz, 19.12kHz and 19.52kHz, after recognizing according to the received sound wave signal. Then, the second client may calculate that a doppler frequency offset value between the frequency value of the generated frequency offset and the original frequency value is 0.12kHz, so that the second client may send 0.12kHz to the server.

In this embodiment, the second client receives the sound wave sent by the first client, decodes the sound wave to generate a second identifier, and sends a login request to the server according to the second identifier and the frequency value of the received sound wave. The server may determine a target client from the second clients by analytically comparing the second identifier with the first identifier.

S4: and determining a target client from the second clients of which the second identifiers are matched with the first identifiers according to the sound wave characteristic values.

In this embodiment, when the second identifier matches the first identifier, the second client may participate in a user login process initiated by the first client. If the second identification is not matched with the first identification, it is indicated that the second client is possibly too far away from the first client, the received sound wave signal is inaccurate, and the recognized character string is also inaccurate. In addition or alternatively, the acoustic signal received by the second client is sent by other clients than the first client, in which case the second client should not be able to participate in the user login process initiated by the first client.

In this embodiment, the way that the second identifier matches with the first identifier may include at least one of the following:

the second identifier is the same as the first identifier;

the second identification and the first identification meet the corresponding relation of a preset algorithm.

Specifically, the second identifier may be the same as the first identifier in terms of content of the second identifier being the same as that of the first identifier. The second identifier and the first identifier satisfy a predetermined algorithm corresponding relationship, and may be obtained by performing a decryption operation on the received second identifier according to a predetermined decryption algorithm, for example, DES3 algorithm or AES algorithm, and determining that the second identifier matches the first identifier when the decrypted second identifier is the same as the first identifier. Or, a weighting operation may be performed on the received second identifier, for example, a binary number of the second identifier may be subjected to a weighting operation to obtain a weighted second identifier, and it is determined that the second identifier matches the first identifier when the weighted second identifier is the same as the first identifier. Of course, matching the second identifier with the first identifier may also include other ways, and the embodiments of the present application are not limited to the above list.

In an actual application scenario, when two clients are making user login requests, the distance between the two clients is often short. In this case, an included angle between a connection direction between the two clients and the direction of the relative motion is often small, and then the doppler frequency offset generated between the two clients is often large. Thus, as the distance between two clients increases, the corresponding doppler frequency offset tends to become smaller. Based on this, in this embodiment, the server may select the target client from the at least one second client after determining according to the frequency value of the sound wave sent by the at least one second client. Specifically, for example, the server may rank the frequency values of the received sound waves, and take the second client corresponding to the sound wave with the largest frequency value as the target client.

In an embodiment of the application, the determining, according to the sound wave feature value, a target client from among second clients whose second identifiers match the first identifiers includes:

and taking the second client corresponding to the sound wave with the second identifier matched with the first identifier and the maximum frequency value as a target client.

In this embodiment, as can be seen from the above description, when the first client and the at least one second client move in the opposite direction, due to the doppler effect and the difference between the speeds of the first client and the at least one second client moving in the opposite direction, the frequency increase values of the sound waves received by the at least one second client are different, so that the frequency value of the at least one sound wave received by the at least one second client has the maximum value. Therefore, when the at least one second client sends the frequency of the sound wave received by the at least one second client to the service server, the service server may perform judgment according to the frequency value of the received at least one sound wave, and determine the second client corresponding to the maximum frequency value, where the second client corresponding to the sound wave with the maximum frequency value is the target client.

In one embodiment of the present application, the frequency value may comprise a doppler frequency offset value.

In this embodiment, as can be seen from the above, when the first client and the at least one second client move in the opposite direction, due to the doppler effect, the frequency value of the sound wave received by the at least one second client is increased, and the difference between the increased frequency value and the original frequency value may be the doppler frequency offset value. Therefore, at least one second client may only send the doppler bias value to the server, and the server may determine the doppler bias value according to the received doppler bias value, thereby determining the corresponding second client.

In one embodiment of the present application, the sound wave characteristic value may further include an intensity value of the sound wave;

accordingly, when there are a plurality of the maximum frequency values, the second client corresponding to the sound wave having the maximum frequency value and the maximum intensity value may be used as the target client.

As can be seen from the foregoing embodiments, the second client corresponding to the sound wave with the largest frequency value may be taken as the target client, but in an actual scenario, there may be a plurality of second clients corresponding to the largest frequency value. In this embodiment, the maximum frequency value may indicate that the user makes an included angle between the relative movement direction of the two clients and the connection direction between the two clients smaller. However, the intensity attribute of the sound wave may represent the intensity of the sound wave received by the second client, and the intensity value of the received sound wave is larger as the distance between the second client and the first client is closer. When the included angle between the relative movement direction of the two clients and the connection direction between the two clients is the minimum and the distance between the two clients is the shortest, it can be determined that the second client is the target client. Therefore, when there are a plurality of the maximum frequency values, the second client corresponding to the sound wave having the maximum frequency value and the maximum intensity value may be used as the target client.

In one embodiment of the present application, the frequency value of the sound wave may include an average value of frequencies of sound waves received by the second client within a predetermined period of time.

In this embodiment, the first client may send sound waves to the at least one second client. When relative motion occurs between the first client and the at least one second client, the frequency of the sound wave received by the at least one second client will increase or decrease due to the doppler effect. And the doppler frequency offset values are different according to the difference of the relative movement speeds, so that the rising or falling values of the frequency of the sound wave received by the at least one second client are also different, and thus the average values of the frequency of the sound wave within the preset time period are also different. For example, the first client sends four sound waves with frequencies of 19kHz, 20kHz, 20.2kHz and 20.4kHz to the second client a and the second client B within 400ms, the frequency offset value of the second client a due to the doppler effect is 500Hz, and the frequency offset value of the second client B due to the doppler effect is 200 Hz. The average value of the frequency of the sound wave received by the second client a is higher than the average value of the frequency of the sound wave received by the second client B within 400 ms. Therefore, after the server receives the frequency values sent by the two second clients, the client corresponding to the maximum frequency value can be determined to be the second client a, and the second client a is the target client.

In this embodiment, when the server analyzes that the second identifier matches the first identifier, a target client may be determined from the at least one second client according to the frequency value of the sound wave, and data transmission is performed by using the characteristics of the sound wave, so that not only is efficiency improved, but also user experience is improved.

In this embodiment, the method may further include:

calculating a distance between the first client and the second client;

screening out the second client side with the distance smaller than a preset distance threshold;

accordingly, the determining a target client from the second clients whose second identities match the first identity comprises:

and determining a target client from the screened second clients with the second identifications matched with the first identifications.

As described above, in an actual application scenario, the distance between two clients that are performing user login requests is often short, and in a scenario where multiple second clients send login requests, if a server processes the login requests one by one, more time is inevitably consumed, the cost is high, and the efficiency is low. In this embodiment, before determining the target client, the second client may be preliminarily screened according to the distance parameter. For example, the distance between the first client and the second client may be obtained, and the second client whose distance is smaller than a preset distance threshold may be screened out. The distance may be calculated according to the geographical location information of the first client and the second client. In one embodiment of the present application, the login request sent by the first client and the second client may include geographical location information. In an embodiment of the present application, the server may send a request to the first client and the second client to obtain the geographic location information. Fig. 2 is a schematic diagram of a scenario in which second clients are screened according to distances provided by the present application, and as shown in fig. 2, a server receives second identifiers sent by multiple second clients, such as PC-A, PC-B and PC-C, and calculates, according to geographical location information of the first client and the second clients, distances a, B, and C between the first client and PC-A, PC-B and PC-C, respectively. And setting a preset distance threshold value as R, screening out second client sides PC-A and PC-B with the distance smaller than R, and then, processing login requests sent by the PC-A and the PC-B by the server only, so that the processing time can be shortened, and the processing efficiency can be improved.

In another embodiment of the present application, the method may further include:

calculating the time between the first client side sending the login request and the second client side sending the login request;

screening out second clients with the time less than a preset time threshold;

In this embodiment, the login request does not generally extend the request time indefinitely, andin practical application scenarios, after the first client sends the login request, the sound wave is generally sent to the target client in a short time. Therefore, in this embodiment, the second client may be preliminarily screened according to the time parameter before determining the target client. For example, the time that the first client sends the login request is far from the time that the target client sends the login request may be calculated, and the second clients whose time is less than the preset time threshold may be screened out. The time may be calculated according to time information when the first client and the second client send login requests. In an embodiment of the present application, time information may be included in the login request sent by the first client and the second client. In an embodiment of the present application, the server may send a request to the first client and the second client, and obtain time information when the first client and the second client send login requests. Fig. 3 is a schematic diagram of a scenario of filtering second clients according to time provided in the present application, and as shown in fig. 3, a server receives second identifiers sent by multiple second clients, such as PC-1, PC-2, …, and PC-6, where the first client is at T₀The login request is sent at the moment, and the second clients PC-1, PC-2, … and PC-6 respectively send login requests at T₁Time, T₂Time …, T₆And sending a login request at any time. Respectively calculating the time interval between the login requests sent by the second clients PC-1, PC-2, … and PC-6 and the login request sent by the first client, and setting a preset time threshold T_thScreening out the time interval less than T_thAs shown in fig. 3, the second client has the screening results of PC-1, PC-2, PC-3, and PC-4, and thereafter, the server can only process the login request sent by PC-1, PC-2, PC-3, and PC-4, which can shorten the processing time and improve the processing efficiency.

acquiring a preset authorization identifier set of the first client and a physical or network identifier of the second client;

screening out a second client side of which the physical or network identifier is contained in the preset authorization identifier set;

In a practical scenario, the first client may only authorize the specified client to log in, for example, a small mobile phone may only authorize the small PC, PAD, etc. to log in. At this time, a preset authorization identifier set corresponding to the first client may be set, where the preset authorization identifier set may include a physical identifier or a network identifier corresponding to an authorized client, where the physical identifier may be a physical address of the authorized client, such as a MAC address, and the network identifier may be a network address of the authorized client, such as an IP address, a network card physical address, and the like. In this embodiment, the second client may be preliminarily screened according to the physical or network identifier before determining the target client. For example, a second client having a physical or network identity included in the preset set of authorized identities may be screened out.

In this embodiment, the second client is preliminarily screened before the target client is determined, so that the time for subsequently determining the target client can be shortened, and the processing efficiency of the server can be improved.

Based on the foregoing method for determining a target client, another aspect of the present application further provides a server, fig. 4 is a schematic block structure diagram of an embodiment of the server provided in the present application, and as shown in fig. 4, the server 40 may include:

a first identifier generating unit 41, configured to generate a first identifier according to a preset rule in response to the login request;

a target client determining unit 44, configured to determine a target client from the second clients whose second identities match the first identities.

According to the method and the server for determining the target client, the first identifier can be encoded through sound waves, encoded sound wave information is sent to the at least one second client in a Doppler frequency offset mode, the frequency value of the sound waves after frequency offset is decoded by the at least one second client, and therefore the first identifier corresponding to the sound wave signals after frequency offset can be obtained. And analyzing the sound wave frequency value sent by the at least one second client by using the server, so that the target client in the user login process can be determined from the plurality of second clients. Compared with the prior art, the method has the advantages that the user can complete account login at the target client only by completing simple operations of sending a login request and shaking the first client at the first client without complex and complicated operations such as inputting an account number and scanning a two-dimensional code, so that the user experience can be improved, and the user login efficiency can be improved.

Fig. 5 and fig. 6 are an interaction diagram and a schematic diagram of an application scenario of a target client, respectively, provided by the present application, where after a first user opens a pay client on a client PC-a, a program of the pay client controls the client PC-a to open a microphone, and at this time, the microphone is in a listening state. The first user initiates a login request of a short distance through a pay bank client running on a first mobile terminal, the login request can be sent to a pay bank service server, and the login request can include a pay bank account of the first user. After receiving the login request, the service server of the treasury payment may calculate a first identifier "397620" according to the account number of the treasury payment and the date and time of the current time by using a hash algorithm, and bind the first identifier with the login request and send the first identifier to the client of the treasury payment on the first mobile terminal.

After receiving the first identifier, the payer client on the first mobile terminal may automatically turn on the speaker of the first mobile terminal, and may sequentially play the sound waves with frequency values corresponding to the numbers in "397620" according to the preset correspondence between the characters and the sound wave frequency values. As shown in fig. 6, at this time, the first user may hold the first mobile terminal to move towards the target client PC-a with an acceleration a, for example, may flick the first mobile terminal towards the target client PC-a. Thus, as shown in fig. 6, the frequency value of the sound wave received by the target client PC-a is doppler-shifted, and meanwhile, the client a and the client B may also receive the sound wave, and the frequency value of the received sound wave may also be doppler-shifted. The pay bank client of the client PC-a, the client a, and the client B may decode the frequency value of the frequency shifted sound wave to obtain the first identifier "397620". The pay bank clients on the client PC-a, the client a, and the client B may use "397620" as the second identifier, and send the second identifier and the frequency value of the received sound wave as a login request to the pay bank service server.

As described above, the payer service server may receive a login request from other terminals such as the client a and the client B, in addition to the login request from the payer client on the target client PC-a. And the payment service server extracts a login request with the second identifier matched with the first identifier from a plurality of requests, and takes the client corresponding to the sound wave with the maximum frequency value as a target client. Since the client PC-a is closest to the first mobile terminal, the target client may be a paymate client on the client PC-a. Thereafter, the Payment treasure service server can send authorization login information to the target client PC-A, and the client PC-A can display a logged-in Payment treasure interface.
