Each group member in the target group has a communication secret key, and the communication secret key encrypts and decrypts communication contents in the communication process of the group members. When a group member wants to send a message, a terminal operated by the group member acquires a communication key stored in an instant communication application program of the group member, encrypts and encapsulates the message through an encryption algorithm and then transmits the message to a server, the server forwards the encrypted and encapsulated message to terminals operated by other group members, the terminals operated by other group members acquire the communication key stored in the respective instant communication application program when receiving the message, decrypt and unseal the message through a decryption algorithm, and the message content sent by the group member is displayed in a group page.
The group owner of the group can operate the terminal thereof to generate the graphic code of the target group, and after the graphic code is generated, the group owner can share the graphic code to the group and can also share the graphic code to other friends in the communication list.

The embodiment of the present application takes the process of sharing the graphic code by the group owner as an example, and other situations are similar and will not be described again.
According to the method for group joining processing based on the graphic code, provided by the embodiment of the application, under the condition that the server does not know the communication key of the target group, the first terminal sends a group graphic code request to the server to generate the graphic code of the target group, wherein the graphic code can be a two-dimensional code, a bar code and the like. When the second terminal wants to join the target group, the second terminal can scan the graphic code, send a group owner joining request to the server, enter the target group and acquire the communication key of the target group.

Step 502, the server obtains the group mask of the target group and sends the group mask to the first terminal.
Where the group mask is a mask of the communication key of the target group, the group mask may be a randomly generated binary string. The communication key is a string of digital codes with specified length randomly generated by the instant communication application program when a group owner creates a target group, and is used for encrypting communication contents when all parties in the group communicate, so that the communication contents are not stolen during the communication process of all the communication parties.
In implementation, when the group owner creates the target group, the server may randomly generate a group mask, and store the generated group mask and the group identifier of the target group in a correspondence table established in advance. After receiving the group pattern code request sent by the first terminal, the server may search the group mask of the target group in the group identifier and group mask correspondence table of the target group according to the group identifier of the target group carried in the group pattern code request, and send the group mask to the first terminal.
Optionally, after receiving the group pattern code request sent by the first terminal, the server may also generate a group mask of the target group according to the group identifier of the target group carried in the group pattern code request, and send the group mask to the first terminal.
In step 503, the first terminal generates a feature code corresponding to the group mask.
The feature code corresponding to the group mask may be a hash value obtained by performing a hash operation on the group mask, and the hash operation is irreversible.
In implementation, after receiving a group mask of a target group sent by a server, a first terminal generates a hash value of the group mask through a hash operation, as a feature code corresponding to the group mask.
Step 504, the first terminal obtains the locally stored communication key of the target group, and performs a confusion operation on the communication key and the group mask to obtain a confusion code.
The obfuscation operation is to encrypt the communication key by using an obfuscation encryption algorithm, and the obfuscation operation may be an exclusive-or operation, and the obfuscation operation may be an inverse operation. The local storage may be for storage at an instant messaging application. The communication key is generated by the group owner terminal when creating the target group, and can be a string of randomly generated digital codes with specified length, when the group owner generates the graphic code, the graphic code can be sent to other friends, and the other friends can obtain the communication key of the target group after entering the group by scanning the graphic code.
In implementation, when the terminal of the group owner, i.e. the first terminal, is creating the target group, the instant messaging application may automatically generate the communication key of the target group, and store it locally in the instant messaging application. After the first terminal obtains the group mask of the target group, the first terminal can obtain the locally stored communication key, and performs the confusion operation on the communication key and the group mask to obtain the confusion code.
For example, the communication key acquired by the first terminal into the target group may be 11110000, the group mask may be 10001110, the obfuscating operation may be an exclusive-or operation, and the communication key and the group mask are subjected to the exclusive-or operation, that is, the communication key and the group mask are equal to 0 and not equal to 1, so that the obfuscated code is 01111110.
In step 505, the first terminal generates a graphic code of the target group based on the confusion code, the feature code and the group identifier.
In the implementation, the instant messaging application program comprises a graphic code generation algorithm, and the graphic code is preset with a certain digit. In this embodiment, the graphic code at least includes a first field, a second field and a third field, the first field may be used for recording the obfuscation code, the second field may be used for recording the feature code, and the third field may be used for recording the group identifier. The graphic code generation algorithm can set '1' to represent black and '0' to represent white, and the first terminal generates the graphic code of the target group by using the graphic code generation algorithm and sends the graphic code to the target terminal. The target terminal may be a second terminal described below.
For example, after the group owner operates the first terminal to generate the graphic code of the target group, the graphic code appears on the target group interface in the instant messaging application program through the processing of the above steps. The group owner can share the graphic code to the group and can also share the graphic code to other friends in the communication list. After the group owner shares the graphic code to the group, the group member can save the graphic code to the local and can also forward the graphic code to friends in the own communication list.
In step 506, the second terminal reads the confusion code, the feature code and the group identifier of the target group carried in the graphic code.
The second terminal is a terminal that wants to join the target group.
In implementation, when a user wants to join the target group, the second terminal may be operated to start the instant messaging application and log in the second account. The instant messaging application program is provided with an option for scanning a group graphic code, after the second terminal receives the graphic code of the target group, a user operates the second terminal to scan the graphic code, the second terminal firstly recognizes the graphic code into binary number, then obtains the numerical value of each field in the binary number, obtains the confusion code recorded by the first field, the feature code recorded by the second field and the group identifier recorded by the third field, and thus reads the confusion code, the feature code and the group identifier of the target group carried in the graphic code.
Step 507, the second terminal sends a group join request to the server.
The group joining request carries the feature code and the group identifier of the target group.
In implementation, after a user operates a second terminal to scan a graphic code of a target group, the second terminal obtains a confusion code, a feature code and a group identifier of the target group, which are carried in the graphic code, and then the second terminal can generate a group join request, add the feature code and the group identifier of the target group, and then send the group join request to a server.
Step 508, if the feature code of the group mask code is the same as the feature code carried in the group join request, adding the account logged in by the second terminal into the target group, and sending the group mask code to the second terminal.
In implementation, after receiving the group join request sent by the second terminal, the server analyzes the group join request, obtains the group identifier and the feature code of the target group carried in the group join request, and further obtains the group mask of the target group according to the group identifier of the target group. And the server performs hash operation according to the group mask of the target group to generate a hash value of the group mask. Then, the server may compare the generated hash value with the hash value carried in the group join request, and if the generated hash value is the same as the hash value carried in the group join request, may determine the authenticity of the graphic code of the target group scanned by the second terminal, at this time, may join the second account logged in by the second terminal into the target group, and send a group mask to the second terminal.
In step 509, the second terminal determines the communication key of the target group based on the obfuscation code and the group mask.
In implementation, after receiving the group mask of the target group sent by the server, the second terminal may obtain the communication key of the target group through an obfuscating inverse operation according to the group mask of the target group and the obfuscating code carried in the graphic code read in step 506.
For example, the group mask of the target group received by the second terminal may be 10001110, the obfuscating code may be obtained by performing an exclusive-or operation on the communication key and the group mask, and the obfuscating code carried in the graphic code may be 01111110, and then the communication key of the target group may be 11110000 by performing an exclusive-or inversion operation, that is, performing an exclusive-or operation once.
Fig. 6 shows an example of an interaction flow between a server and a terminal in the method for performing group join processing based on a graphic code. As shown in fig. 6, the communication key may be a group cipher, and the graphic code may be a two-dimensional code. When a group owner creates an end-to-end encryption group, a group password is automatically generated and stored locally, the group password can be recorded as psw, the group password is not uploaded to a server, the group server only generates a random mask of the group password at the beginning of creating the group, and the mask can be recorded as mask. When a group owner or a group member wants to generate a two-dimensional code of the group, other users can scan the two-dimensional code into the group, a request for generating the two-dimensional code is sent to the group server, and a mask code of the group is pulled. The group owner end conducts confusion operation on the group password stored locally and the mask of the group to obtain a confusion code, the confusion code can be recorded as psw ^ mask, meanwhile, the mask of the group is conducted with hash operation to obtain a hash value of the mask, the hash operation can be recorded as hash operation, the hash value of the mask can be recorded as mask _ hash, the operation results of the two parts are used as one part of the two-dimensional code, and the two-dimensional code of the group is generated. When the code scanner group enters the two-dimensional code, the confusion code psw ^ mask and the hash value of the mask _ hash can be read. And then the client uploads the hash value to the group server to be used as group entering verification. The cluster server extracts the stored mask of the cluster, performs hash operation to obtain a hash (mask) value, compares the hash (mask) value with a mask _ hash value uploaded by the client, if the hash (mask) value is the same as the mask _ hash value uploaded by the client, the client is considered to scan a correct two-dimensional code, and then the cluster server returns the mask of the cluster to the client. And after receiving the mask of the group, the user side performs inverse operation by using the mask of the group and the confusion operation result read in the two-dimensional code, the inverse operation can be recorded as psw ^ mask ^ mask, the group password of the group is obtained, and the group password is stored.
The technical scheme provided by the embodiment of the application has the following beneficial effects:
in the embodiment of the application, the first terminal performs a confusion operation on the communication key and the group mask of the target group to obtain a confusion code, performs a hash operation on the group mask to obtain a feature code, and generates the graphic code according to the confusion code and the feature code. The server verifies whether the feature code obtained by scanning the graphic code by the second terminal is the same as the feature code obtained by the operation of the server, and if so, the server passes the verification and sends a group mask to the second terminal. And the second terminal carries out operation according to the group mask to obtain the communication key. In the whole process, the server side cannot acquire the communication key of the target group. The method and the device realize that the user side can obtain the communication key of the group by scanning the two-dimensional code under the condition that the server side does not know the group password. Thus, the information security of the group can be improved
