The cloud device generates a graphical verification code for identity verification and a unique identifier of the screen-casting client under the condition that the screen-casting client initiating the webpage casting is determined to be in the cloud conference group room. For example: 10 graphic verification codes are stored in the cloud space, 1 graphic verification code is randomly selected from 10 graphic verification codes each time authentication is needed, the graphic verification code is identified as a graphic verification code a for authenticating the screen projection client, and the graphic verification code is pushed to display equipment for displaying. The unique identification of the screen-casting client can be obtained by performing hash calculation on the ID of a user logged in by the screen-casting client, and after the unique identification is generated, the cloud equipment can store the unique identification in a cloud space and send the unique identification to a mobile phone number bound by the screen-casting client.
For example, in the case of generating the unique identifier and the graphical verification code of the screen projection client, as shown in fig. 5, the video website entry page returned by the cloud device may include the unique identifier entry field and the plurality of graphical verification codes in addition to the video website entry field, and prompt the user to select one of the plurality of graphical verification codes which is the same as the graphical verification code displayed on the display device. The plurality of graphical verification codes can be 4 randomly selected by the cloud device from the stored 10 graphical verification codes, and the graphical verification codes comprise graphical verification codes a identified by the cloud device.

It should be understood that the identification number to be verified, which is input by the user in the unique identification input field shown in fig. 5, is the selected pattern, which is the graphic verification code to be verified. The cloud device judges whether the identification number to be verified is matched with the unique identification, judges whether the graphic verification code to be verified is a graphic verification code a, and determines that malicious attack does not exist in the input of the screen projection client if the graphic verification code a to be verified is verified, namely the video website is trustable. In the embodiment, the identity of the screen projection client is verified based on the pre-generated unique identifier and the graphical verification code so as to determine whether the video website input by the user has malicious attack, and the method is favorable for preventing illegal users who are not in the cloud conference group room from providing illegal websites for the cloud server.
Illustratively, analyzing the web page to obtain irrelevant content in the web page includes:
analyzing the webpage to locate a plurality of windows in the webpage;
acquiring a contribution coefficient of each window in the multiple windows to the determination of a video window to be displayed from the multiple windows;
calculating to obtain a reference value corresponding to each window according to the contribution coefficient;

Specifically, as shown in fig. 6, the cloud device may analyze, by using a machine learning model, a picture presented by a webpage corresponding to the video website to locate a plurality of windows in the webpage, such as: the plurality of windows may include a video window to be presented, a recommended video window for a video website, an advertising window, a video category ranking window (e.g., movies, television shows, educational), etc. For each positioned window, m image frames of the window are obtained within a certain time, then a target image frame is randomly selected from the m image frames, the area ratio of the target image frame to the image of the webpage corresponding to the video website is calculated, and the area ratio is determined as the contribution coefficient c of each window to the determination of the video window to be displayed from the plurality of windows. Such as: in fig. 6, the ratio of the area of the video window to be displayed to the area of the whole web page is used as the contribution coefficient of the video window to be displayed, and since the video window to be displayed in the web page is usually the window with the largest area, the contribution coefficient is usually the largest, that is, the contribution degree of the window to the determination of the content to be displayed at the front end is the highest. Wherein m is an integer greater than 2. For each window, calculating the similarity d between the 1 st image frame and the rest (m-1) image frames in the m image frames to obtain (m-1) similarities, and simultaneously mapping the contribution coefficient of each window to the weight coefficient thereof by adopting a preset formula:
α＝α 2 -α 1 ；
α 2 >α 1 ；
wherein, theta i Weight coefficient representing the ith window, c i Representing the contribution factor of the ith window, alpha representing the formula parameter, alpha 1 ∈[0,1]，α 2 ∈[0,1]And e represents a natural constant. Because the video in the video window to be displayed is played all the time, the (m-1) similarity d of the m image frames shows a decreasing trend, even lower and lower, and the video or advertisement of other windows usually plays circularly or presents a static picture within a certain time, and the (m-1) similarity d is obviously different from the video window to be displayed in the change amplitude, therefore, a decreasing function theta is adopted i Will contribute coefficient c i Mapped to corresponding weight coefficients. That is to say that the weight factor of the video window to be presented is minimal. The similarity d of (m-1) of the ith window is summed to obtain
Wherein d is j And expressing the jth similarity in the (m-1) similarities, and calculating the reference value of the ith window by adopting the following formula:
f i ＝∑ 1≤j≤m-1,1≤i≤n θ i d j ；
wherein f is i A reference value of an ith window is indicated, and n indicates the number of a plurality of windows. Because the (m-1) similarity d of the video window to be displayed is in a decreasing trend, the sum of the similarity d is
The minimum weight coefficient is multiplied by the minimum sum of the similarity, so that the difference of reference values between the video window to be displayed and other video windows is more obvious, the window with the minimum reference value can be visually seen as the video window to be displayed, and the contents displayed by other windows with the reference values which are not the minimum can be determined as irrelevant contents.
203: and shielding the irrelevant content, fusing the webpage after shielding the irrelevant content to the cloud desktop, and pushing the webpage to the display equipment.
In the embodiment of the application, after determining the window corresponding to the irrelevant content, the cloud device shields the window corresponding to the irrelevant content in the webpage to shield the irrelevant content, for example: the windows corresponding to the irrelevant content are shielded in the Uniform Resource Locator (URL) of the web page. The cloud device fuses the webpage with the irrelevant content shielded off to the cloud desktop, and pushes the webpage to the display device so as to play the video in the video window to be displayed on the display device, and therefore refreshing playing of screen projection of the video screen is achieved. Such as: the display device may be a large screen device of a conference room.
It can be seen that, in the embodiment of the application, a user can submit a screen casting request of a video website to a cloud device by triggering a screen casting page control at a screen casting client side, the cloud device responds to the triggering of the screen casting page control and returns a video website input page to the screen casting client side, the user inputs the video website to be cast into the video website input page displayed by the screen casting client side and then submits the video website to the cloud device, the cloud device opens a webpage corresponding to the video website and analyzes the webpage corresponding to the video website to obtain irrelevant content in the webpage corresponding to the video website, the irrelevant content is shielded, the webpage after the irrelevant content is shielded is fused to a cloud desktop and pushed to a display device, the display device only plays the video content in an important video window without playing the irrelevant content displayed by windows such as advertisements, the refreshing playing effect after the video website casting is achieved, the smoothness of the video content displayed in the important video window is favorably guaranteed, and the user experience is improved.
