The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present application, as detailed in the appended claims.

Reference herein to "a plurality" means two or more. "and/or" describes the association relationship of the associated objects, meaning that there may be three relationships, e.g., a and/or B, which may mean: a exists alone, A and B exist simultaneously, and B exists alone.

The scheme provided by the application can be used in a real scene in which an application program runs in a terminal when people use the terminal in daily life, and for convenience of understanding, some terms and application scenes related to the embodiment of the application are first briefly introduced below.

Screen sharing: the terminal comprises a plurality of terminals, wherein at least one terminal shares the picture displayed in the screen with other terminals through a channel, so that the other terminals can see the picture displayed in the screen of the terminal.

Asymmetric encryption: asymmetric encryption algorithms require two keys: public key (public) and private key (Privatekey). The public key and the private key are a pair, and if the public key is used for encrypting data, only the corresponding private key can be used for decrypting the data; if the data is encrypted with a private key, it can only be decrypted with the corresponding public key.

With the development of scientific technology, various terminals have appeared in daily life of people, and people can work, entertain, study, and the like through the terminals. The screen (also referred to as a display screen) is common hardware in the terminal, and for the terminal with the screen, people can realize functions of video call, video playing, interface display, screen sharing and the like in the terminal.

Referring to fig. 1, a scene diagram of a screen sharing scene provided in an exemplary embodiment of the present application is shown. As shown in fig. 1, several terminals 110 and servers 120 are included in the screen sharing scenario.

Among them, the terminal 110 is a terminal in which an application of a screen sharing function is installed. For example, the terminal may be a mobile phone, a tablet computer, an e-book reader, smart glasses, a smart watch, an MP4(Moving Picture Experts Group Audio Layer IV) player, a notebook computer, a laptop portable computer, a desktop computer, and the like.

The server 120 is a server, or a plurality of servers, or a virtualization platform, or a cloud computing service center. Alternatively, the server 120 may be a server corresponding to an application having a screen sharing function in the terminal 110, or may be a server of a manufacturer of the terminal 110.

Optionally, the terminal 110 and the server 120 are connected through a communication network. Optionally, the communication network is a wired network or a wireless network.

Optionally, the wireless network or wired network described above uses standard communication techniques and/or protocols. The Network is typically the Internet, but may be any Network including, but not limited to, a Local Area Network (LAN), a Metropolitan Area Network (MAN), a Wide Area Network (WAN), a mobile, wireline or wireless Network, a private Network, or any combination of virtual private networks. In some embodiments, data exchanged over a network is represented using techniques and/or formats including Hypertext Mark-up Language (HTML), Extensible Markup Language (XML), and the like. All or some of the links may also be encrypted using conventional encryption techniques such as Secure Socket Layer (SSL), Transport Layer Security (TLS), Virtual Private Network (VPN), Internet Protocol Security (IPsec). In other embodiments, custom and/or dedicated data communication techniques may also be used in place of, or in addition to, the data communication techniques described above.

In a possible implementation manner, for example, two terminals (a first terminal and a second terminal) in the plurality of terminals are used, the first terminal and the second terminal may implement screen sharing between the two terminals through an installed application having a screen sharing function, so that the first terminal or the second terminal sees a picture displayed in a screen of the other terminal.

Referring to fig. 2, a flow chart of a screen sharing process according to an exemplary embodiment of the present application is shown. As shown in fig. 2, the screen sharing process may include several steps as follows.

Step 201, a first terminal logs in a target application, and the target application has a screen sharing function.

The first terminal can be installed with a target application, and a user of the first terminal can register account information in the target application and log in the target application through the account information.

Step 202, the first terminal initiates screen sharing through the target application.

The first terminal can initiate screen sharing through the target application and request the server corresponding to the target application to establish a screen sharing room, so that the screen of the first terminal can be shared through the screen sharing room.

In step 203, the target application generates a plaintext validation code.

Alternatively, the server of the target application may create a screen sharing room and generate a plaintext verification code, and the plaintext verification code is returned to the first terminal through the target application, and the first terminal may enter the screen sharing room through the plaintext verification code.

And step 204, the first terminal sends the plaintext verification code to the second terminal through other communication tools.

The other communication tool may be any communication tool that realizes information transmission. And the first terminal sends the plaintext verification code to the second terminal through other communication tools.

In step 205, the second terminal receives the plaintext verification code sent by the first terminal through other communication tools.

Correspondingly, the second terminal can also receive the plaintext verification code sent by the first terminal through other communication tools.

And step 206, the second terminal logs in the target application.

The second terminal may also have a target application installed therein, and a user of the second terminal may also register account information in the target application and log in the target application through the account information.

And step 207, the first terminal and the second terminal respectively input a plaintext verification code in the target application.

The first terminal and the second terminal respectively input the same plaintext verification code in the target application and enter a screen sharing room created by the target application, so that the first terminal can share the picture displayed by the screen of the first terminal to the second terminal.

And step 208, the second terminal displays the screen of the first terminal.

The second terminal can display the picture sent by the first terminal in the screen of the second terminal.

At present, each terminal can implement screen sharing through the above-mentioned manner, so that each terminal is required to register account information in a target application, and each terminal required to implement screen sharing logs in the account information in the target application, which causes a problem of more preconditions when each terminal implements screen sharing. In addition, in the screen sharing process, the plaintext verification code used by the first terminal needs to be sent to another party (the second terminal) through another communication tool, and if the plaintext verification code is acquired by the third terminal, the third terminal can also enter a screen sharing room by using the plaintext verification code and watch a picture shared by the first terminal or the second terminal, so that the problem of low security of screen sharing is caused. Moreover, before the first terminal and the second terminal establish the screen sharing, the transmitted information is only the plaintext verification code, and other information required for the connection process of establishing the screen sharing cannot be transmitted (for example, the screen resolution of the first terminal, the effective time of accessing the screen sharing, and the like).

In order to avoid the problems in the technical scheme and improve the safety of screen sharing established between terminals, the application provides a screen sharing method, which avoids the problem that screen sharing can be realized by acquiring a plaintext verification code in the related technology, so that the safety of screen sharing established between terminals is higher. Referring to fig. 3, a flowchart of a method for sharing a screen according to an exemplary embodiment of the present application is shown. The method can be used in the application scenario shown in fig. 1, and executed by a server in the scenario, as shown in fig. 3, the screen sharing method can include the following steps.

Step 301, receiving a screen sharing request sent by a target terminal, where the screen sharing request is used to request screen sharing with other terminals, and the screen sharing request carries indication identifiers of the other terminals.

The target terminal is provided with a screen sharing application, and the server is a server of the screen sharing application. The server can receive screen sharing requests sent by the target terminal and other terminals provided with the screen sharing application, so that screen sharing is achieved for the terminals.

The screen sharing request sent by the target terminal is used for requesting the server to establish screen sharing with other terminals, wherein the target terminal can carry the indication marks of the other terminals in the screen sharing request, so that the server knows which terminal the target terminal wants to realize screen sharing with. Alternatively, the indication identifier may be a unique number indicating other terminals.

Step 302, acquiring connection information and indication marks of other terminals according to the screen sharing request.

The connection information comprises channel parameters and encryption information, the channel parameters are used for indicating channels adopted by the target terminal for screen sharing with other terminals, and the encryption information is used for indicating information adopted by the server for encrypting the channel parameters.

Optionally, the channel parameter may further include parameters such as a channel number, a channel effective duration, and a channel transmission rate. The encryption information may be an encryption password.

Step 303, encrypting the channel parameters according to the encryption information in the connection information.

That is, the server encrypts the channel parameter according to the encryption information in the connection information, and acquires the encrypted channel parameter.

And 304, generating a target link according to the encrypted channel parameters, wherein the target link is used for establishing screen sharing of the target terminal and other terminals.

The server can package the encrypted channel parameters to generate a target link, so that other terminals can establish screen sharing with the target terminal through the target link.

And 305, sending the target link to other terminals according to the indication marks of other terminals.

And the server sends the generated target link to other terminals according to the obtained indication marks of other terminals.

In summary, a screen sharing request sent by a target terminal is received by a server, the server obtains connection information and indication identifiers of other terminals according to the screen sharing request, the connection information includes a channel parameter and encryption information, the channel parameter is used for indicating a channel used by the target terminal to perform screen sharing with the other terminals, and the encryption information is used for indicating information used by the server to encrypt the channel parameter; the server encrypts the channel parameters according to the encryption information in the connection information; generating a target link according to the encrypted channel parameters; and sending the target link to other terminals according to the indication marks of other terminals. When the target terminal needs to establish screen sharing with other terminals, the server can encrypt the channel parameters through the encryption information contained in the connection information, generate a target link and send the target link to other terminals, so that the encrypted channel parameters need to be decrypted when the other terminals establish screen sharing with the target terminal, the terminal intercepting the target link is prevented from directly acquiring the channel parameters, the transmission safety of the channel parameters is improved, and the screen sharing safety is improved.

In order to avoid the problems in the technical scheme and improve the safety of establishing screen sharing between terminals, the application also provides a screen sharing method, which avoids the problem that screen sharing can be realized by acquiring a plaintext verification code in the related technology, so that the safety of establishing screen sharing between terminals is higher. Referring to fig. 4, a flowchart of a method for sharing a screen according to an exemplary embodiment of the present application is shown. The method can be used in the application scenario shown in fig. 1, and executed by the terminal in the scenario, as shown in fig. 4, the screen sharing method can include the following steps.

Step 401, receiving a target link sent by a server; the target link is used for establishing screen sharing of the target terminal and other terminals.

In fig. 1, when another terminal wants to establish screen sharing with the target terminal, the other terminal may send the screen sharing request to the server, and accordingly, the server may obtain a target link according to the process shown in fig. 3 and send the target link to the target terminal.

Step 402, responding to the trigger operation of the target link, sending a decryption request to the server, where the decryption request is used to instruct the server to decrypt the encrypted channel parameter in the target link, and the channel parameter is used to instruct the target terminal to share the channel used by the screen with other terminals.

After the target link is triggered in the target terminal, the target terminal may send a decryption request to the server, so that the server decrypts the encrypted channel parameter in the target link, thereby obtaining the channel parameter. Optionally, the channel parameter may further include parameters such as a channel number, a channel effective duration, and a channel transmission rate.

And step 403, receiving the channel parameters returned by the server.

That is, the server responds to the decryption request sent by the target terminal, and returns the channel parameters obtained after decryption to the target terminal, and the target terminal directly receives the channel parameters sent by the server.

And step 404, establishing screen sharing with other terminals according to the channel parameters.

And the target terminal accesses the channel indicated by the channel parameter according to the received channel parameter, thereby realizing screen sharing with other terminals.

In summary, after receiving a target link sent by a server and used for establishing screen sharing between the target terminal and other terminals, the target terminal sends a decryption request to the server by responding to a trigger operation on the target link, where the decryption request is used to instruct the server to decrypt an encrypted channel parameter in the target link, and the channel parameter is used to instruct the target terminal to share a channel used for screen sharing with other terminals; and according to the channel parameters returned by the server, screen sharing is established with other terminals. When the target terminal needs to establish screen sharing with other terminals, the target terminal needs to decrypt the channel parameters through the request server to acquire the channel parameters shared by the screens, so that screen sharing is achieved, the terminal intercepting the target link is prevented from directly acquiring the channel parameters, the transmission safety of the channel parameters is improved, and the screen sharing safety is improved.

The embodiments shown in fig. 3 and 4 are described below by way of example with respect to interaction between a target terminal and a server.

In a possible implementation manner, when the target terminal is used as an initiator for establishing screen sharing this time, the screen sharing method provided by the present application may be as follows. Referring to fig. 5, a method flow diagram of a screen sharing method according to an exemplary embodiment of the present application is shown. The method can be used in the application scenario shown in fig. 1, and is executed by the terminal and the server in the scenario, as shown in fig. 5, the screen sharing method can include the following steps.

Step 501, the target terminal responds to the sending operation of the screen sharing request, and acquires the connection information and the indication identification of other terminals.

The screen sharing request is used for requesting screen sharing with other terminals, and the connection information comprises channel parameters and encryption information; the encryption information is used to indicate information by which the server encrypts the channel parameters.

In a possible implementation manner, after a screen sharing application installed in a target terminal is opened, the target terminal may send a screen sharing request through a control in a target application interface by displaying the target application interface. The target application interface comprises an input box for sending control and indication marks of other terminals, and the sending control is used for sending a screen sharing request to the server. And the target terminal acquires the connection information and the indication marks of other terminals by triggering the sending operation of sending the screen sharing request in the application interface.

Referring to fig. 6, an interface diagram of a target application interface according to an exemplary embodiment of the present application is shown. As shown in fig. 6, a target application interface 600 displayed by the target terminal includes an identification input box 601 and a sending control 602. The user may input an indication identifier of another terminal in the identifier input box 601, and trigger the sending control 602 to send a screen sharing request to the server. Optionally, the indication identifier of the other terminal is a Subscriber Identity Module (SIM) number of the other terminal or a device number of the other terminal.

Optionally, the target terminal may obtain, in response to the triggering operation on the sending control, the content included in the input box as the indication identifier of the other terminal. For example, in fig. 6, if the user inputs the indication identifier "123 × 432" of the other terminal in the identification input box in the target application interface, after the user triggers the sending control 602, the target terminal may obtain "123 × 432" contained in the identification input box as the indication identifier of the other terminal.

Optionally, the target terminal may further respond to the trigger operation on the sending control, and select one channel from currently idle channels as a channel used by the target terminal to perform screen sharing with other terminals; acquiring channel parameters of a channel adopted by a target terminal for screen sharing with other terminals; acquiring an encryption mode set in a target terminal; acquiring encryption information according to the encryption mode of the target terminal; and using the channel parameter and the encryption information as connection information.

That is, in the embodiment of the present application, when acquiring the connection information, the target terminal selects one free channel as a channel for transmitting screen shared data from among the channels on which the communication connection can be currently established by itself, and acquires the channel parameter of this channel. For example, the target terminal knows that the channel one is currently in an idle state through communication with the base station, and the target terminal may share the channel one as a screen and acquire a channel parameter of the channel one. Optionally, the channel parameter may be a channel ID of the channel, an effective duration of the channel, a transmission rate of the channel, and the like.

Optionally, after the channel parameters are obtained, the target terminal may further obtain an encryption mode preset in the target terminal. For example, a developer of the target terminal may set an encryption method for encrypting the connection information in advance in the target terminal, and after the target terminal acquires the connection information, encrypt the connection information according to the encryption method. In this embodiment of the present application, the preset encryption mode in the target terminal may be asymmetric encryption, that is, the target terminal side encrypts with a uniform public key, and the other side receiving the connection information decrypts with a corresponding private key.

In a possible implementation manner, the target application interface shown in fig. 6 further includes a selection control of an encryption manner, and the target terminal may further obtain the selected encryption manner as the encryption manner set in the target terminal in response to a trigger operation on the selection control. Referring to FIG. 7, an interface diagram of another target application interface related to FIG. 6 according to an exemplary embodiment of the present application is shown. As shown in fig. 7, a target application interface 700 displayed by the target terminal includes an identification input box 701, a sending control 702, and a selection control 703. The user may input an indication identifier of another terminal in the identifier input box 601, trigger the sending control 602 to send a screen sharing request to the server, and also trigger the selecting control 703 to select an encryption mode in the target terminal. Referring to fig. 8, an interface diagram of an encryption selection interface related to fig. 7 according to an exemplary embodiment of the present application is shown. As shown in fig. 8, a target application interface 800 displayed by a target terminal includes an encryption selection interface 801 and an encryption mode 802. After the user triggers the selection control 703 in fig. 7, the encryption selection interface 801 shown in fig. 8 may be displayed, the user may select a corresponding encryption manner, and accordingly, the target terminal may use the encryption manner selected by the user as the encryption manner set in the target terminal.

Optionally, after obtaining the encryption mode, the target terminal may use an encryption password used by the encryption mode as encryption information, and finally use the obtained encryption information and the channel parameter as connection information to obtain the connection information. The default encryption scheme shown in fig. 8 is asymmetric encryption, and the encryption password used in the default encryption scheme is a public key held by the target terminal. The fingerprint encryption method shown in fig. 8 is to encrypt the fingerprint information stored in another terminal, and the encryption password used in the encryption method is the fingerprint information stored in another terminal. The image encryption method shown in fig. 8 is to encrypt image information stored in another terminal, and the encryption password used in the encryption method is image information stored in another terminal. Optionally, the image information and the fingerprint information may be searched by the server and obtained and returned to the target terminal.

Step 502, the target terminal encrypts the connection information in an asymmetric encryption manner.

The preset encryption mode in the target terminal is asymmetric encryption, and after the target terminal acquires the connection information through the steps, the acquired connection information can be encrypted according to the asymmetric encryption mode.

In step 503, the target terminal carries the encrypted connection information and the indication identifier of the other terminal in the screen sharing request, and sends the screen sharing request to the server.

That is, when the target terminal sends the screen sharing request to the server, the target terminal carries the encrypted connection information and the obtained indication identifiers of the other terminals in the screen sharing request, so that the server can obtain the indication identifiers of the connection information and the other terminals through the screen sharing request.

In step 504, the server receives a screen sharing request sent by the target terminal.

The target terminal is provided with a screen sharing application, and the server is a server of the screen sharing application. After the target terminal sends the screen sharing request, correspondingly, the server can receive the screen sharing request from the target terminal, so that the fact that the target terminal needs to share the screen with other terminals is known.

And 505, the server acquires the connection information and the indication identifiers of other terminals according to the screen sharing request.

In this embodiment, because the screen sharing request received by the server carries the connection information and the indication identifiers of the other terminals, the server may parse the received screen sharing request to obtain the connection information and the indication identifiers of the other terminals carried in the screen sharing request. For example, the indication mark of the other terminal in fig. 6 is "123 × 432", and in this step, after the server parses the screen sharing request, the encrypted connection information of the target terminal and the indication mark "123 × 432" may be obtained.

Step 506, the channel parameters are encrypted according to the encryption information in the connection information.

Optionally, because the asymmetric encryption mode is set in advance by the screen sharing application and the server, the target terminal may encrypt the connection information through a public key, and the server may decrypt the connection information through a private key, the server may decrypt the encrypted connection information according to the corresponding private key to obtain the channel parameter and the encrypted information in the connection information, and encrypt the channel parameter according to the encrypted information in the connection information to obtain the encrypted channel parameter. For example, the encrypted information is an asymmetric encrypted public key, and the server may re-encrypt the channel parameter in the connection information by using the public key to obtain the encrypted channel parameter.

And 507, the server generates a target link according to the encrypted channel parameters, wherein the target link is used for establishing screen sharing between the target terminal and other terminals.

In a possible implementation manner, in order to save the steps of the server, the server may also directly encapsulate the obtained connection information as the target link without re-encrypting the channel parameters and encapsulating the channel parameters as the target link.

And step 508, the server sends the target link to other terminals according to the indication marks of other terminals.

Namely, the server sends the generated target link to other terminals according to the obtained indication marks of other terminals.

In a possible implementation manner, before sending the target link to the other terminal, the server may further obtain state information of the other terminal according to the indication identifier of the other terminal, determine a sending manner of the target link to the other terminal according to the state information of the other terminal, and send the target link to the other terminal according to the determined sending manner of the target link. The state information is used for indicating that other terminals are logged in or not logged in the server. For example, the server may perform authentication through the indication identifier of the other terminal and the login interface of the server, if the terminal corresponding to the indication identifier of the other terminal logs in the server through the login interface of the server, the server may determine that the state information of the terminal is in a login state, and if the terminal corresponding to the indication identifier of the other terminal does not log in the server through the login interface of the server, the server may determine that the state information of the terminal is in an unregistered state. That is, the login state may indicate that the other terminal is logged in the server, and the unregistered state may indicate that the other terminal is not logged in the server.

Optionally, the server responds to the state information of the other terminal to indicate that the other terminal is not logged in (unregistered state) in the server, and the server sends the target link to the other terminal in a short message manner according to the indication identifier of the other terminal.

Optionally, when the indication identifier of the other terminal is the SIM number of the other terminal, the server may directly invoke the short message application of the target terminal, and send the short message to the other terminal through the target terminal. When the indication marks of other terminals are the equipment numbers of other terminals, the server can also inquire a number list in the server through the equipment numbers, wherein the number list comprises the corresponding relation between the equipment numbers and the SIM numbers, the server acquires the SIM numbers of other terminals according to the number list, and then calls the short message application of the target terminal, and sends the short message to other terminals through the target terminal.

Optionally, if the channel parameter includes three parameters, namely, a channel number, a channel effective duration and a channel transmission rate, when the server sends the target link to the other terminal in the form of a short message, the server may further edit the channel effective duration and the channel transmission rate in the channel parameter into the short message, and prompt the other terminal in a text form, so that the other terminal establishes screen sharing with the target terminal in time.

Optionally, the server responds to the state information of the other terminal to indicate that the other terminal logs in (login state) in the server, and the server sends the target link to the other terminal in a system information manner according to the indication identifier of the other terminal.

Optionally, when the other terminal is in a login state in the server, the server may send the target link to the other terminal in a manner of sending system information to the account information of the other terminal in the server by using the account information of the target terminal in the server, so that the other terminal receives the target link, and screen sharing is achieved through the target link.

In addition, when the state information of other terminals is not logged in, the target link is sent to the other terminals in a short message mode, so that the condition that account information of both sides can receive screen sharing under the condition of logging in the related technology is avoided, and the flexibility of screen sharing establishment is improved.

In addition, the target link is sent to other terminals in a short message mode, and the short message can also carry other more information, such as the effective duration of the channel, and indicates that the target link is effective within the effective duration of the channel at this time by other terminals, so that the information transmission amount in the screen sharing establishing process is increased, and the accuracy of screen sharing establishing is improved.

In a possible implementation manner, the step of the target terminal selecting one channel from currently idle channels as a channel used by the target terminal for screen sharing with other terminals, and acquiring the channel parameters of the channel used by the target terminal for screen sharing with other terminals may also be performed by the server, and the encryption of the channel parameters may be specified by the target terminal.

Referring to fig. 9, a method flow diagram of a screen sharing method according to an exemplary embodiment of the present application is shown. The method can be used in the application scenario shown in fig. 1, and is executed by the terminal and the server in the scenario, as shown in fig. 9, the screen sharing method can include the following steps.

In step 901, the target terminal responds to the sending operation of the screen sharing request, and acquires the encrypted information and the indication identifiers of other terminals.

Optionally, the process of obtaining the encrypted information and the indication identifiers of the other terminals in this step may refer to the process of obtaining the encrypted information in the process of obtaining the connection information in step 501, and the process of obtaining the indication identifiers of the other terminals, which is not described herein again.

And step 902, the target terminal carries the encrypted information and the indication identifiers of other terminals in the screen sharing request and sends the screen sharing request to the server.

That is, when the target terminal sends the screen sharing request to the server, the target terminal carries the obtained indication identifiers of the encrypted information and the other terminals in the screen sharing request, so that the server can obtain the indication identifiers of the encrypted information and the other terminals through the screen sharing request.

Step 903, the server receives a screen sharing request sent by the target terminal.

And step 904, the server acquires the encrypted information and the indication marks of other terminals according to the screen sharing request.

In this embodiment, since the screen sharing request received by the server carries the encrypted information and the indication identifiers of the other terminals, the server may parse the received screen sharing request to obtain the encrypted information and the indication identifiers of the other terminals carried in the screen sharing request.

Step 905, the server selects one channel from the currently idle channels as a channel used by the target terminal to perform screen sharing with other terminals.

Step 906, the server obtains channel parameters of a channel used by the target terminal for screen sharing with other terminals.

That is, after receiving the screen sharing request, the server may allocate an idle channel to the target terminal as a channel for the target terminal to perform screen sharing with other terminals, and optionally, the manner in which the server acquires the idle channel may also refer to the manner in which the terminal acquires the idle channel in step 501, which is not described herein again.

In step 907, the server encrypts the channel parameters according to the encryption information in the connection information.

Optionally, when the encrypted information is fingerprint information stored in other terminals; the server needs to inquire fingerprint information stored in other terminals from the server; and encrypting the channel parameters according to the fingerprint information stored in other terminals. When the encrypted information is the fingerprint information stored in other terminals, the server can acquire the fingerprint information of the terminal from the prestored corresponding relation table containing the indication identifier of each terminal and the fingerprint information stored in each terminal through the indication identifiers of the other terminals, so that the channel parameters are encrypted by using the fingerprint information.

Optionally, when the encrypted information is image information stored in other terminals; inquiring image information stored in other terminals from the server; and encrypting the channel parameters according to the image information stored in other terminals. Similarly, the server may also previously establish a correspondence table corresponding to the indication identifier of each terminal and the image information stored in each terminal, and when the encrypted information is the image information stored in other terminals, the server may obtain the image information of the terminal from the correspondence table containing the indication identifier of each terminal and the image information stored in each terminal, which is stored in advance, through the indication identifiers of other terminals, so as to encrypt the channel parameter using the image information.

Step 908, the server generates a target link according to the encrypted channel parameters, and the target link is used for establishing screen sharing between the target terminal and other terminals.

In step 909, the server sends the target link to the other terminal according to the indication identifier of the other terminal.

Optionally, the implementation manners of step 908 to step 909 may also refer to the descriptions in step 507 to step 508, which are not described herein again.

In a possible implementation manner, when the target terminal is the receiving side (corresponding to the target terminal being another terminal) for establishing the screen sharing this time, the screen sharing method provided by the present application may be as follows. Referring to fig. 10, a method flow diagram of a screen sharing method according to an exemplary embodiment of the present application is shown. The method can be used in the application scenario shown in fig. 1, and is executed by the terminal and the server in the scenario, as shown in fig. 10, the screen sharing method can include the following steps.

1001, a target terminal receives a target link sent by a server; the target link is used for establishing screen sharing of the target terminal and other terminals.

Optionally, corresponding to the two sending modes of the server, the target terminal may correspondingly receive the target link sent by the server in the system information mode, or the target terminal may also receive the target link sent by the server in the short message mode.

In step 1002, the target terminal sends a decryption request to the server in response to a trigger operation on the target link, where the decryption request is used to instruct the server to decrypt the encrypted channel parameters in the target link.

The channel parameter is used for indicating a channel adopted by the target terminal for screen sharing with other terminals.

Alternatively, the trigger operation of the target link may be a click operation of the user. After a user clicks a target link received in a target terminal, the target terminal can be triggered to pull up a screen sharing application installed in the target terminal, a decryption request is sent to a server through the screen sharing application, and the server is requested to decrypt encrypted channel parameters in the target link.

In a possible implementation manner, the target terminal can also respond to the trigger operation of the target link and display an information acquisition interface; acquiring information acquired by a target terminal through an information acquisition interface as decryption information; and carries the decryption information in the decryption request. This approach corresponds to the scheme described above in fig. 9, in which the encrypted information is determined by the initiator of the screen sharing, and how the recipient performs decryption.

Optionally, please refer to fig. 11, which illustrates an interface schematic diagram of an information collecting interface according to an exemplary embodiment of the present application. As shown in fig. 11, an information collecting area 1101 is included in a target terminal 1100, in which a user can input fingerprint information, and the target terminal acquires the collected fingerprint information as decryption information and carries the decryption information in a decryption request. The decryption information may be obtained in a manner corresponding to the fingerprint information stored in the target terminal.

Optionally, please refer to fig. 12, which shows an interface schematic diagram of another information collecting interface according to an exemplary embodiment of the present application. As shown in fig. 12, an information acquisition area 1201 is included in the target terminal 1200, in which the user can input face information, and the target terminal acquires the acquired face information as decryption information and carries it in a decryption request. The decryption information may be obtained in a manner corresponding to the encrypted information being image information stored in the target terminal.

In step 1003, the server receives a decryption request sent by the target terminal.

And step 1004, the server decrypts the encrypted channel parameters according to the encryption information according to the decryption request to acquire the channel parameters.

After receiving the decryption request, the server knows that the encrypted channel parameters in the target link need to be decrypted, and in the above asymmetric encryption mode, the server also uses the private key held by the server to decrypt when decrypting, so as to obtain the channel parameters. In the above encryption method selected by the user, the server may receive decryption information sent by the receiver shared by the screen during decryption, and may decrypt the decryption information sent by the receiver to obtain the channel parameter.

Corresponding to the above encryption mode selected by the user, the target terminal can carry the decryption information in the decryption request and send the decryption request to the server, and the server can analyze the decryption request according to the decryption request to obtain the decryption information: and decrypting the encrypted channel parameters according to the decryption information to obtain the channel parameters. For example, the decryption information is fingerprint information of the target terminal, when the target terminal sends the decryption request, the target terminal carries the acquired fingerprint information in the decryption request, the decryption request carrying the decryption information is sent to the server, the server analyzes the decryption request, obtains the fingerprint information in the decryption request, and decrypts the encrypted channel parameters by using the fingerprint information. If the fingerprint information is the same as the fingerprint information encrypted before, the server can acquire the channel parameters and return the channel parameters to the target terminal. If the fingerprint information is different from the fingerprint information that was encrypted before, the server may not be able to obtain the channel parameters.

Step 1005, the server sends the channel parameter to the target terminal.

Optionally, if the server acquires the channel parameter, the server sends the acquired channel parameter to the target terminal. If the server does not acquire the channel parameters, the server can return error information to the target terminal to prompt the target terminal to resend the decryption request.

Step 1006, the target terminal receives the channel parameters returned by the server.

Step 1007, the target terminal establishes screen sharing with other terminals according to the channel parameters.

After obtaining the channel number in the channel parameter, the target terminal can actively access to the channel with the channel number, receive the screen sharing data sent by the opposite side or send the screen sharing data of the target terminal, and realize screen sharing with other terminals.

And step 1008, the target terminal displays a screen sharing interface, and the screen sharing interface is used for displaying display interfaces of other terminals or display interfaces of the target terminal.

After the target terminal and other terminals establish screen sharing, the target terminal can display a screen sharing interface, and display interfaces of other terminals or own display interfaces are displayed in the screen sharing interface. If the screen sharing interface shows the display interfaces of other terminals, the target terminal receives the screen sharing data sent by other terminals and shows the screen sharing data in the screen of the target terminal. If the screen sharing interface shows the own display interface, the target terminal is the own screen data sent to other terminals at the moment. The embodiment of the present application does not limit the display of the screen sharing interface.

In a possible implementation manner, the number of the indication marks of the other terminals is at least two, and the target terminal can display the display interfaces of the other terminals in a split-screen display manner. For example, three terminals establish screen sharing, wherein the screen sharing includes a target terminal and two other terminals, and when the target terminal wants to display screen data of the two other terminals in its own screen, display interfaces of the other terminals can be displayed in a split screen manner. Referring to fig. 13, an interface diagram of a screen sharing interface according to an exemplary embodiment of the present application is shown. As shown in fig. 13, the target terminal 1300 includes a first interface 1301 and a second interface 1302. The first interface 1301 is displayed when the target terminal receives the screen data sent by the first terminal, and the second interface 1302 is displayed when the target terminal receives the screen data sent by the second terminal.
