And step S110, acquiring the identity characteristic information of the terminal 100.

In the embodiment of the present application, the terminal 100 may be pre-installed with a screen projection program, and the screen projection program may be a screen projection application or a screen projection applet, etc. The screen projection program is used to assist the terminal 100 in performing screen projection operation, for example, triggering operation of acquiring the identity characteristic information of the terminal 100.

As an embodiment, the screen projection program may be first run on the terminal 100. The operation of triggering to acquire the identity characteristic information of the terminal 100 may be triggered when the screen projection program starts to run, for example, after responding to an operation of opening the screen projection program by a user, the screen projection program runs, and the operation of acquiring the identity characteristic information of the terminal 100 is immediately and automatically triggered. As another embodiment, after the screen projection program is run, the user may manually trigger the operation of acquiring the identity characteristic information of the terminal 100. For example, after the screen projection program is run, an interactive interface of the screen projection program is displayed, an interactive unit for triggering to acquire the identity characteristic information of the terminal 100 is arranged on the interactive interface, and when a user triggers the interactive unit, the operation for acquiring the identity characteristic information of the terminal 100 is triggered. The interactive elements may be icons, buttons, list options, etc. In other embodiments, the operation of acquiring the identity characteristic information of the terminal 100 may also be triggered by a gesture in an interactive interface displaying a screen projection program. It is to be understood that the present invention is not limited thereto, and other manners that can be used to trigger the obtaining operation of the identity information of the terminal 100 can be adopted.

As an embodiment, after triggering the obtaining operation of obtaining the identity feature information of the terminal 100, the terminal 100 may prompt the user to input the identity feature information of the terminal 100. The reminding can be performed by means of words, voice and the like, and is not limited herein.

In this embodiment, the terminal 100 identity characteristic information refers to information for verifying the identity of the user. The terminal 100 identity characteristics may include, but are not limited to, fingerprint information, face information, iris information, and voiceprint information. The terminal 100 may acquire information of the user through a fingerprint sensor, or may acquire face information and iris information of the user by calling a camera, or may acquire voiceprint information of the user by calling a microphone, thereby acquiring identity characteristic information of the terminal 100.

The identity characteristic information of the terminal 100 is obtained to obtain the identity information of the user who is screening and used for subsequent identity verification. The terminal 100 identity characteristic information is adopted for verification, a user can operate easily, extra data irrelevant to the user does not need to be obtained, and safety risks caused by adoption of verification codes or two-dimensional codes can be prevented.

And step S120, sending the identity characteristic information of the terminal 100 for pairing verification. The terminal 100 identity characteristic information is used for pairing verification with the screen projection identity characteristic information. Wherein, the screen projection identity characteristic information is acquired by the screen projection device 200.

In this embodiment, the terminal 100 sends the acquired identity characteristic information of the terminal 100 for pairing verification. Optionally, the terminal 100 may send the identity characteristic information of the terminal 100 to the server 300, and perform pairing verification at the server 300.

For example, the screen shot identity information is a fingerprint, and the screen shot identity information of the terminal 100 is a human face. When the types of the screen projection identity characteristic information and the screen projection identity characteristic information of the terminal 100 are different, the two types of information need to be unified before pairing verification is carried out.

As an implementation manner, various types of identity characteristic information of a target user may be stored in advance, the identity of the user may be determined through one type of identity characteristic information of the target user, then the identity characteristic information of the user authentication type of the user is acquired, and the identity characteristic information of the authentication type is subjected to pairing authentication.

When the pairing verification result is that the terminal 100 and the screen projection identity feature information are verified, the identity feature information of the same user is represented, and the terminal 100 and the screen projection device 200 are successfully paired and verified.

And when the pairing verification result is that the terminal 100 and the screen projection device 200 do not pass the verification, the pairing verification fails. The failure to pass the verification may be that the terminal 100 identity information and the screen shot identity information are not identity information of the same user. The terminal 100 identity information or the screen shot identity information may be invalid without being verified. The valid time of the terminal 100 identity feature information can be preset, interference of expired information on subsequent pairing verification can be prevented, and the time of the pairing verification can be controlled.

And step S140, screen projection data are sent according to the pairing verification result, so that the screen projection equipment 200 performs screen projection display according to the screen projection data.

When the pairing verification result is that the pairing verification result passes the verification, the terminal 100 may send screen projection data to the screen projection device 200, so that the screen projection device 200 performs screen projection display according to the screen projection data. Alternatively, the terminal 100 may transmit the screen projection data to the server 300, and the server 300 forwards the screen projection data to the screen projection device 200. Alternatively, the terminal 100 may directly transmit the screen projection data to the screen projection device 200 with which the pairing is successful.

In some embodiments, the screen projection data may be data of a screen currently displayed by the display device of the terminal 100. As shown in fig. 3, the screen projection data in fig. 3 is data of a screen displayed by the current display device of the terminal 100.

For detailed description of step S210, please refer to step S110, which is not described herein again.

And step S220, sending the identity characteristic information of the terminal 100 for pairing verification.

In some embodiments, the screen projection device 200 includes a plurality of screen projection sub-devices. The screen projection sub-equipment can independently display and also can independently acquire the identity characteristic information of the screen projection sub-equipment. The screen projection sub-device can also be used for displaying together with other screen projection sub-devices. For example, in a large-area space, such as a large lecture hall, a conference room or a classroom, a plurality of projection sub-devices are required to be arranged at different positions in the space, so that viewers at different positions can clearly view the screens. For another example, in some scenes needing large-screen display, the area of a single screen projection sub-device cannot meet the display requirement, and sometimes the large-screen display requirement can be met by splicing a plurality of screen projection sub-devices. For another example, in some display scenes, a plurality of file display requirements exist, and for the convenience of the user, a plurality of screen projection sub-devices can be arranged, each screen projection sub-device can display one or more display files, so that the display modes can be enriched, and various requirements of the user can be met. In order to meet the use requirement of a multi-screen scene of a user, the embodiment of the application may support the terminal 100 to be connected with a plurality of screen-projecting sub-devices.

The obtained multiple pairing verification results may also have partial verification, that is, the terminal 100 and partial screen projection sub-device are paired and verified. In some cases, all of the obtained pairing verification results may fail, that is, the terminal 100 and all of the screen projection sub-devices do not pass the pairing verification.

In the present embodiment, it is necessary to determine a pair verification result that passes verification among the acquired plurality of pair verification results. And then screen projection sub-equipment corresponding to the screen projection sub-identity characteristic information corresponding to the verified pairing verification result is determined, so that the screen projection operation of the next step is continued with the screen projection sub-equipment which passes the verification.

Alternatively, the same screen projection data may be sent to a plurality of screen projection sub-devices, so that the plurality of screen projection sub-devices display the same screen. The method can be applied to large-space application scenes such as large lecture halls, large classrooms and the like. As shown in fig. 6, the terminal 100 sends the same screen projection data to the first screen projection sub-device 200a and the second screen projection sub-device 200b, so that the first screen projection sub-device 200a and the second screen projection sub-device 200b display the same screen.

And the plurality of screen projection sub-devices receive the same screen projection sub-device and display the same screen projection picture.

In other embodiments, the same screen projection data may be sent to multiple screen projection sub-devices, so that the multiple screen projection sub-devices collectively display the same screen projection picture, and different pictures displayed by the multiple screen projection sub-devices are merged together to be just a complete screen projection picture. That is to say each screen displays a part of the complete picture. The large-screen display method and device can be suitable for scenes needing large-screen display, a single screen projection sub-device cannot meet requirements, and the requirements for large-screen display can be met by splicing a plurality of screen projection sub-devices. As shown in fig. 7, the third screen projection sub-device 200c, the fourth screen projection sub-device 200d, the fifth screen projection sub-device 200e, and the sixth screen projection sub-device 200f collectively display a screen projection screen of the terminal 100.

Optionally, only the screen projection data required to be displayed by the screen projection sub-device may be sent to the corresponding screen projection sub-device.

In still other embodiments, different screen projection data may be sent to the plurality of screen projection devices 200, so that the plurality of screen projection devices 200 display different screens. In some implementations, the different screens displayed by the multiple screen projection devices 200 can be content independent of each other. The method is suitable for scenes needing to display various files, and the user can display different files through different screen projection sub-devices, so that better interaction and demonstration effects are achieved. As shown in fig. 8, the seventh projection sub-device 200g displays a projection screen displayed on the window B of the terminal 100, and the eighth projection sub-color 200h displays a projection screen displayed on the window C of the terminal 100.

It can be understood that if at least one pairing verification result in the plurality of pairing verification results is verified, the terminal 100 displays a screen-shot file selection interface.

And the screen projection file selection interface can respond to the operation of a user and control the picture needing screen projection. For example, the operation of selecting the file, the blackboard book and the like needing to be screened can be selected.

In some embodiments, a screen-shot file selection interface may be displayed when the pairing verification passes. One or more screen projection devices 200 display the screen projection according to the control of the same screen projection file selection interface.

In other embodiments, when there are a plurality of pairing verification results that pass, a plurality of screen-shot file selection interfaces may be correspondingly displayed, and optionally, the screen-shot file selection interfaces may be displayed in a window form. The size of the window may be adjusted. The terminal 100 may display a plurality of screen-shot file selection interfaces simultaneously, or may display only one screen-shot file selection interface, and the other screen-shot file selection interfaces may be displayed in a switching manner.
