Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
In the embodiment of the invention, after the remote control connection is established between the controlled end and the main control end, the controlled end needs to send the screenshot of the current screen to the main control end in real time, so that the data on the current screen of the controlled end can be displayed on the screen of the main control end in real time. When the remote control is performed, the display data on the screen of the controlled end can be seen by the user of the main control end without reservation, so that the user information security of the controlled end is threatened. According to the embodiment of the invention, before the controlled terminal carries out screen capture operation on the current screen, preprocessing operation is carried out on the current screen in advance, so that preset sensitive data on the current screen cannot be seen on the screen of the main control terminal, and therefore, the privacy information of the user at the controlled terminal can be ensured not to be leaked.
The following description will be made of specific contents of examples.
An embodiment of the present invention provides a method for displaying screen data in remote control, and referring to fig. 1, the method is a flowchart of the method for displaying screen data in remote control provided in the embodiment of the present invention, and the method includes: ,
s101: the method comprises the steps that before a controlled terminal captures a current screen, preprocessing operation is carried out on the current screen, so that preset sensitive data on the current screen cannot be seen on a screen of a main control terminal.
S102: and the controlled terminal captures the screen of the current screen subjected to the preprocessing operation and sends the screen capture result to the main control terminal, so that the main control terminal displays screen data according to the received screen capture result.
The controlled terminal and the main control terminal in the embodiment of the invention can be PC terminals, and can also be mobile terminals, such as smart phones, tablet computers and the like. In addition, the preset sensitive data in the embodiment of the invention is privacy data of the controlled end user, such as data which is forbidden to be known by other users, such as passwords, personal privacy information and the like.
After the remote control connection is established between the master control end and the controlled end, the controlled end needs to send the screen shot of the current screen to the master control end in real time. In the embodiment of the invention, before the controlled terminal sends the screenshot of the current screen to the main control terminal, the current screen is preprocessed firstly, so that the sensitive data on the current screen cannot be seen when the screenshot of the current screen is sent to the main control terminal for displaying.
The embodiment of the present invention provides three specific implementation manners for performing a preprocessing operation on the current screen of the controlled end, and it should be noted that the following three implementation manners are not to be taken as limitations to the preprocessing operation performed on the current screen of the controlled end in the embodiment of the present invention.
In the first implementation manner, because the screen display data visible to the controlled end user is distributed in multiple layers of the screen, before the controlled end performs screen capture on the current screen, the layer (hereinafter referred to as a first layer) where the preset sensitive data is located is first determined, and then, after the first layer in the current screen of the controlled end is removed, screen capture operation is performed on the current screen. At this time, the screen capture result does not include the sensitive data, that is, the sensitive data of the controlled terminal is not displayed on the screen by the main control terminal.
In a second embodiment, before performing screen capture on a current screen, a controlled end first determines a layer (hereinafter referred to as a second layer) where preset sensitive data is located, and then, the controlled end replaces the second layer with a transparent layer and performs screen capture on the current screen. Because the transparent layer replaces the second layer, the screen capture result does not include the sensitive data, and the sensitive data of the controlled end cannot be displayed on the screen by the main control end. In addition, the controlled end replaces the second layer with the transparent layer, so that data displayed on a current screen cannot be influenced, and the purpose of protecting privacy data of a user at the controlled end can be achieved.
In a third embodiment, before the controlled terminal performs screen capture on the current screen, a display area where sensitive data on the current screen is located is first determined, and specifically, coordinate information of the display area where the sensitive data is located is included. Secondly, the controlled end covers the display area where the sensitive data is located according to the coordinate information of the display area where the sensitive data is located and the like. In particular, the display area where the sensitive data is located may be covered with an invisible black box. And after the controlled end covers the display area where the sensitive data is located, capturing the screen of the current screen. And finally, the sensitive data of the controlled terminal cannot be displayed on a screen by the main control terminal.
In practical application, the sensitive data includes a user password, the controlled terminal can judge whether the type of the input box on the current screen is a password input box before the controlled terminal captures the current screen, and if the type of the input box on the current screen is the password input box, the controlled terminal determines the password input box as the display area of the sensitive data. Subsequently, the controlled terminal may cover the password input box with a black box so that the password input box is invisible. At this time, the controlled terminal performs screen capture on the current screen again, and the obtained screen capture result cannot see the sensitive data of the controlled terminal user after the screen capture result is displayed by the main control terminal.
In the embodiment of the invention, the controlled terminal carries out screen capture on the current screen which is subjected to any one of the preprocessing operations, and sends the obtained screen capture result to the main control terminal. And after receiving the screen capture result, the main control end displays the screen capture result on a screen, wherein the sensitive data of the controlled end cannot be seen in the data displayed on the screen of the main control end, so that the privacy safety of a user at the controlled end is ensured.
In the screen data display method in remote control provided by the embodiment of the invention, the controlled terminal carries out preprocessing operation on the current screen before carrying out screen capture on the current screen, so that preset sensitive data on the current screen cannot be seen on the screen of the main control terminal. And the controlled terminal captures the screen of the current screen subjected to the preprocessing operation and sends the screen capture result to the main control terminal, so that the main control terminal displays screen data according to the received screen capture result. Compared with the prior art, the method and the device have the advantages that the preprocessing operation is performed on the current screen in advance before the controlled terminal performs the screen capturing operation on the current screen, so that the preset sensitive data on the current screen cannot be seen on the screen of the main control terminal, and the safety of the privacy information of the user at the controlled terminal can be guaranteed.
