And after receiving the login credential information sent by the instant messaging server, the service server forwards the login credential information to the terminal. The terminal can locally store the login credential information and log in the instant messaging server based on the login credential information.

With reference to the flowchart of the method for logging in the target instant messaging application shown in fig. 1 and fig. 2, the processing flow of the method may include the following steps:

in step 101, when a target instant messaging application is started, if a terminal does not store a security number of the terminal in the target instant messaging application, a security number allocation request is sent to an instant messaging server by the terminal.

In implementation, the terminal is provided with a target instant messaging application, and when the target instant messaging application is started, the terminal can judge whether the target instant messaging application stores a security number of the terminal. The security number corresponds to the terminal one by one, and can uniquely represent the terminal. If the security number of the terminal is not stored in the target instant messaging application, for example, the target instant messaging application is installed for the first time by the terminal or the target instant messaging application is initialized, the terminal may send a security number allocation request to the instant messaging server.

Optionally, the security number allocation request carries device information of the terminal, where the device information includes a device manufacturer identifier and a device model. In order to enable the instant messaging server to improve the accuracy of distinguishing the terminals, the terminals can also add the device information related to the terminals into the security number allocation request before sending the security number allocation request to the instant messaging server.

Optionally, if the terminal determines that the security number of the terminal is stored in the target instant messaging application, the process may jump to step 103.

In step 102, when receiving a security number allocation request sent by a terminal, an instant messaging server determines the security number of the terminal and sends the security number to the terminal.

In implementation, when receiving a security number allocation request sent by a terminal, the instant messaging server may determine a unique security number for the terminal. The instant messaging server can be a security number pool which is established in advance, wherein enough security numbers which are different from each other are stored, and when a security number distribution request sent by a terminal is received, one security number can be selected from the security number pool to serve as the security number of the terminal. Or, the instant messaging server may further randomly generate a non-repeating UUID (universal Unique Identifier) for the terminal as the security number of the terminal when receiving the security number assignment request sent by the terminal. And then, the instant communication server can establish the corresponding relation between the security number and the terminal and store the security number and the terminal. Then, the instant messaging server may transmit the generated security number to the terminal.

Optionally, for a case that the security number allocation request carries the device information of the terminal, the corresponding processing of the instant messaging server may be as follows: and adding a corresponding item of the security number of the terminal and the equipment information of the terminal in the pre-established corresponding relation between the security number and the equipment information.

In implementation, the instant messaging server may pre-establish a corresponding relationship between the security number and the device information, where the corresponding relationship between the device information of the terminal to which the security number is assigned and the security number is stored. When the instant messaging server determines the security number of the terminal in the process, the corresponding item of the security number of the terminal and the equipment information can be added into the corresponding relation between the security number and the equipment information.

Through the process, the terminal can receive the security number sent by the instant messaging server and store the security number in the local.

Optionally, the terminal and the instant messaging server may transmit sensitive data such as a security number through an HTTPS (Hyper Text Transfer Protocol over Secure Socket Layer), so as to prevent the sensitive data from being hijacked by an intermediate network device.

In step 103, when receiving a login authentication instruction triggered by a user operation, the terminal requests a service server for login authentication based on the security number and login information input by the user.

In implementation, when the terminal determines that the security number is stored in the target instant messaging application or receives the security number sent by the instant messaging server, the terminal may determine whether the login credential information is stored in the target instant messaging application. If the login credential information is not stored, the terminal can display the login interface of the target instant messaging application. The user can input login information such as an account and/or a password in the login interface, click a login confirmation option and trigger a login verification instruction. Furthermore, the terminal may send both the security number and login information input by the user to the service server to request login authentication.

Optionally, the specific processing that the terminal requests the service server for login verification based on the security number and the login information input by the user may be as follows: sending a login verification request carrying login information to a service server, and receiving a verification success character string sent by the service server after the login information is verified; and sending a login credential acquisition request carrying the verification success character string and the security number to the service server.

In an implementation, the terminal may add login information input by the user to the login authentication request and transmit the login authentication request to the service server. If the login information passes the verification, the terminal can receive a verification success character string fed back by the service server, and the verification success character string is used for representing a login result and indicating that the terminal can log in the service server. When the terminal receives the successful verification character string, the security number can be obtained, the successful verification character string and the security number are added into the login certificate obtaining request, and the login certificate obtaining request is sent to the service server.

Optionally, if the terminal determines that the login credential information of the terminal is stored in the target instant messaging application, it may jump to step 107.

The service server may receive the login information and the security number sent by the terminal, may receive the login information and the security number simultaneously, or may notify the security number sent by the terminal after the login information is verified.

Optionally, the service server may receive a login authentication request carrying login information sent by the terminal, and send an authentication success string to the terminal if the login information is authenticated; and receiving a login credential acquisition request which is sent by the terminal and carries the verification success character string and the security number.

In implementation, when the service server receives a login authentication request sent by the terminal, the service server can acquire login information therein and authenticate the login information. If the authentication is passed, a string of authentication success characters may be determined for the terminal.

Optionally, when the user registers the account, the account may be composed of numbers and/or letters, and the service server may generate a user number for the account so as to identify the account in the service server and the instant messaging server. After the verification is passed, the service server can also acquire the account in the login information to determine the corresponding user number. The service server may store the user number and the verification success string in the verification record in a corresponding manner. The business service can also establish the corresponding relation between the user number and the terminal to indicate that the terminal logs in the account corresponding to the user number.

The service server can send the verification result to the terminal, and if the verification result is that the verification is passed, the service server can also send the character string with successful verification to the terminal at the same time so as to inform the terminal that the verification is passed. Then, the service server may receive a login credential acquisition request sent by the terminal. The service server can obtain the successful verification character string, inquire whether the successful verification character string exists in the verification record, if so, obtain the user number corresponding to the successful verification character string, and add the user number and the security number to the login credential distribution request.

In step 104, if the login information is verified by the service server, the service server sends a login credential distribution request of the corresponding terminal to the instant messaging server.

Wherein, the login credential distribution request carries the security number. Optionally, the login credential allocation request may further carry a user number, so that the instant messaging server stores a correspondence between the user number and the terminal.

In implementation, if the service server passes the authentication of the terminal in the above process, a login credential allocation request carrying a security number may be sent to the instant messaging server, so as to obtain login credential information that can be used for logging in the instant messaging server for the terminal.

In step 105, when receiving a login credential allocation request carrying a security number of a terminal sent by a service server, an instant messaging server determines login credential information of the terminal, sends the login credential information of the terminal to the service server, and adds a corresponding item between the security number of the terminal and the login credential information of the terminal in a pre-established corresponding relationship between the security number and the login credential information.

In implementation, the instant messaging server may be pre-established with a corresponding relationship between the security number and the login credential information, in which the security number and the login credential information of the authenticated terminal are stored. When receiving a login certificate allocation request sent by a service server, the instant messaging server can randomly generate a non-repeated UUID for the terminal as login certificate information of the terminal. The login credential information and the security number may be UUIDs with different formats, and are not limited herein. Furthermore, the instant messaging server can add the corresponding item of the security number of the terminal and the login credential information of the terminal in the corresponding relation of the security number and the login credential information. Then, the instant messaging server can send login credential information of the terminal to the service server, so that the service server forwards the login credential information to the terminal.

Optionally, for a case that the login credential allocation request sent by the service server also carries the user number, the instant messaging server may further store the user number when storing the security number of the terminal and the corresponding item of the login credential information of the terminal.

In step 106, the service server receives the login credential information of the terminal sent by the instant messaging server, and forwards the login credential information to the terminal.

In implementation, after the service server forwards the login credential information to the terminal, the terminal may receive the login credential information sent by the service server and store the login credential information in the local.

In step 107, the terminal sends a login request to the instant messaging server.

The login request carries a security number of the terminal and login credential information of the terminal.

In implementation, when the terminal determines that the target instant messaging application stores the login credential information or receives the login credential information sent by the service server, the terminal may add the security number and the login credential information of the terminal to the login request and send the login request to the instant messaging server.

Optionally, in a possible scenario, when the target instant messaging application is started, if the security number of the terminal is stored in the target instant messaging application and the login credential information of the terminal is stored in the target instant messaging application, a login request is sent to the instant messaging server.

Optionally, the login request further carries the device information, so that the instant messaging server is used to distinguish different terminals. In addition, the login request can also carry the use times corresponding to the login credential information.

Optionally, the terminal may encrypt the login request, and the corresponding processing may be as follows: and encrypting the login request, calculating a corresponding hash signature for the encrypted login request, and sending the encrypted login request and the hash signature corresponding to the encrypted login request to the instant messaging server.

In implementation, the terminal may encrypt the login request based on a set encryption method, and then calculate a corresponding hash signature based on a set hash algorithm according to the encrypted login request. Furthermore, the terminal can send the encrypted login request and the corresponding hash signature to the instant messaging server together.

In step 108, the instant messaging server receives a login request which is sent by the terminal and carries the security number of the terminal and the login credential information of the terminal, and if a corresponding item between the security number of the terminal and the login credential information of the terminal exists in the pre-established corresponding relationship between the security number and the login credential information, the terminal is determined to be successfully logged in.

In implementation, after receiving a login request sent by a terminal, the instant messaging server can obtain a security number and a login credential therein. Then, the instant messaging server can judge whether the corresponding item of the security number and the login credential information of the terminal exists in the corresponding relation of the security number and the login credential information. If the terminal is successful in login, the terminal is indicated to pass login verification. After the terminal successfully logs in the instant messaging server, the user can use the target instant messaging application in the terminal to carry out instant messaging with other users.

If the terminal does not exist, the terminal may steal login credential information of other terminals, so that the security number and the login credential do not have a corresponding relationship, the instant messaging server may determine that the terminal has failed to log in, and avoid the terminal stealing the login credential information from logging in the instant messaging server.

Optionally, a flowchart of determining the terminal login result by the instant messaging server may be as shown in fig. 3, where the process in fig. 3 is described as follows:

for the above encryption situation, the instant messaging server may decrypt the login request, and the corresponding processing may be as follows: and receiving the encrypted login request sent by the terminal and a hash signature corresponding to the encrypted login request, and if the hash signature is verified correctly based on the encrypted login request, decrypting the encrypted login request to obtain the login request carrying the security number of the terminal and the login credential information of the terminal.

In implementation, the instant messaging server may receive the encrypted login request sent by the terminal and the hash signature corresponding to the encrypted login request, and then the instant messaging server may calculate the hash signature corresponding to the encrypted login request according to the received encrypted login request based on the same hash algorithm as the terminal. Generally, the hash signature calculated by the instant messaging server is the same as the hash signature sent by the terminal, that is, the instant messaging server can verify the hash signature correctly. If the login request sent by the terminal is hijacked and tampered in the transmission process, the instant messaging server calculates a hash signature according to the tampered login request, the hash signature is generally different from the hash signature sent by the terminal, and the instant messaging server can determine that the hash signature fails to be verified. Once the verification of the hash signature is determined to fail, the instant messaging server can determine that the terminal login fails.

If the instant communication server determines that the hash signature verification is successful, the login request can be decrypted based on a set decryption mode, so that the security number and the login credential information of the terminal are obtained, and the next step of processing is carried out.

Optionally, the login request may further carry the number of times of use corresponding to the login credential information, and the instant messaging server may obtain the number of times of use, compare the number of times of use corresponding to the locally stored login credential information, and determine whether the number of times of use of the login request is equal to the number of times of use of the local storage plus 1. If not, the instant messaging server can determine that the terminal fails to log in. If so, further processing may be performed. In a possible situation, after the login request is hijacked, data playback may be performed, the number of times of use in the login request during normal data playback does not change, and when the instant messaging server receives the login request with the number of times of use for the second time, the instant messaging server may determine that the terminal has failed to login, so as to avoid the influence of the data playback on the security of the instant messaging application.

Similar to the step 108, after determining that the number of usage times of the login request is equal to the number of usage times of the local storage plus 1, the instant messaging server may determine whether the security number of the terminal and the corresponding item of the login credential information exist in the corresponding relationship between the security number and the login credential information. If not, it may be determined that the terminal has failed to log in. If the user number exists, the corresponding user number can be obtained, and the next step of processing is carried out.

Optionally, for a case that the login request further carries the device information, corresponding processing of the instant messaging server may be as follows: and determining whether a corresponding item of the security number of the terminal and the equipment information of the terminal exists in the pre-established corresponding relation between the security number and the equipment information.

In implementation, the instant messaging server may obtain the security number and the device information in the login request, and then may determine whether a corresponding item between the security number of the terminal and the device information of the terminal exists in a corresponding relationship between the locally stored security number and the device information. In a possible situation, the login credential information of the legal terminal is hijacked, and when the malicious terminal uses the login credential information, because the device information of the malicious terminal is different from that of the legal terminal, the instant messaging server cannot search for the corresponding item of the security number of the malicious terminal and the device information of the terminal. If the terminal does not exist, the instant communication server can determine that the terminal login fails, and the login credential information can only be used by the corresponding terminal. If so, the terminal login success can be determined, and the connection between the obtained user number and the terminal can be calibrated. Therefore, the user can use the account corresponding to the user number to carry out instant messaging on the terminal.

It should be noted that, the verification of the number of times of use and the verification of the corresponding relationship between the security number and the device information may exist in one process at the same time as the above-described process, so as to further improve the security of the login target instant messaging application, and may also be used in one process alternatively, and the processing procedure is similar to the above-described content, and is not described in detail here.

In the case of verification of the number of uses, the processing of the instant messaging server may be as follows: and if the corresponding item of the security number of the terminal and the login credential information of the terminal exists in the pre-established corresponding relation between the security number and the login credential information, and the using frequency corresponding to the login credential information is equal to the using frequency corresponding to the locally stored login credential information plus 1, determining that the terminal is successfully logged in.

In the case of verifying the corresponding relationship between the security number and the device information, the processing of the instant messaging server may be as follows: and if the corresponding item of the terminal security number and the login credential information of the terminal exists in the pre-established corresponding relationship between the security number and the login credential information, and the corresponding item of the terminal security number and the terminal device information exists in the pre-established corresponding relationship between the security number and the device information, determining that the terminal login is successful.

In addition, if the terminal is lost, the user may input the device information and the loss report information such as an account of the lost terminal through a security center of the instant messaging application, and then send a loss report request, which may include the loss report information, to the instant messaging server. After receiving the loss report request, the instant messaging server can acquire loss report information in the loss report request, delete a corresponding item in the corresponding relation between the security number and the equipment information according to the equipment information, determine a corresponding user number according to the account, and delete a corresponding item in the corresponding relation between the security number and the login credential information according to the user number. After the above processing, when other users find the lost terminal, the instant messaging application cannot be used through the account which the terminal has logged in, so that the information security of the user is ensured.
