[0031] In order to make the purpose, technical solutions and advantages of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in combination with the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.
[0032] As mentioned in the background technology section, current remote tools such as Sunflower and Todesk will share the content currently displayed on the mobile phone when remotely controlling the mobile phone. However, there is a lot of sensitive data on personal mobile phones, including social chat or financial software applications, which may lead to privacy leakage. Moreover, even if the controlled end closes the running software involving sensitive data, the authorized control end can still open the closed application and view the current window content.
[0033] In order to solve the above problems, the present application provides a display solution based on remote control of mobile phones, which is applied to the scenario of remote control of mobile phones, so that users cannot view sensitive information of remote mobile phones, thereby improving security. The following non-limiting description of the specific implementation scheme is given through several examples or embodiments.
[0034] Reference Figure 1 and Figure 2 , Figure 1 Schematic diagram of a flow chart of a display method based on remote control of mobile phone security provided in an embodiment of the present application. Figure 2 A schematic diagram of the remote control interaction principle provided by an embodiment of the present application. The method is applied to a mobile device, that is, a controlled device in a remote control scenario, and the method can be specifically executed by an application installed on the mobile device for implementing remote control.
[0035] like Figure 1 and Figure 2 As shown, the display method based on remote control of mobile phone security in this embodiment at least includes the following steps:
[0036] Step S101: After establishing a remote control connection with a control terminal device, obtaining a start instruction sent by the control terminal device.
[0037] The startup instruction is used to instruct the mobile device to start an application (APP) installed on the mobile device.
[0038] Specifically, after the mobile device and the control end device successfully establish a connection, the control end device can send instructions to the mobile device to control the mobile device, such as starting an application, controlling the display interface of the opened application, etc. When you want to start an application on the mobile device, the control end device can send a start instruction to the mobile device, and the start instruction can be triggered by clicking on the corresponding application.
[0039] Step S102: determining whether the target application corresponding to the start instruction is a preset sensitive application.
[0040] Specifically, when the mobile device obtains the start-up instruction sent by the control terminal device, it first determines whether the target application corresponding to the start-up instruction is a preset sensitive application. Among them, the preset sensitive application refers to an application that contains privacy information or that the user does not want to be viewed by the remote user, such as an instant messaging APP, a mobile banking APP, or other user-defined APP.
[0041] Step S103: If yes, after starting the target application, when acquiring the image of the display interface of the target application, blur processing is performed on each frame of the image.
[0042] Specifically, when step S102 determines that the target application to be started is a sensitive application, it indicates that the target application contains private information that the user does not want to be viewed. Therefore, after starting the target application, before the display interface is displayed to the controlled device, each frame of the display interface of the target application is blurred so that the remote user cannot obtain the private information from the blurred image.
[0043] When blurring is performed, the entire image may be blurred, or only a portion of the image may be blurred, which may be specifically set according to actual needs.
[0044] In some embodiments, blurring each frame may specifically include: adding a mask to each frame. By adding the mask, the content of all or part of the area in the picture can be covered to achieve blurring.
[0045] It can be understood that if the judgment result of step S102 is no, it can be processed according to the conventional method, which will not be repeated here.
[0046] Step S104: Send the blurred image to the control terminal device for display.
[0047] In some embodiments, the specific implementation method of step S104 may include: sending the blurred image to the control terminal device via streaming for display.
[0048] Specifically, the real-time streaming images of the controlled end can be transmitted to the control end device through efficient data transmission and image encoding technology. The streaming method can improve efficiency and reduce configuration requirements.
[0049] Based on the above scheme, after the mobile device establishes a remote control connection with the control end device, after the mobile device obtains the startup instruction sent by the control end device, it first determines whether the target application corresponding to the startup instruction is a preset sensitive application; if so, after starting the target application, when obtaining the screen of the display interface of the target application, each frame of the screen is blurred, and then the blurred screen is sent to the control end device for display. This setting can avoid sending the content of sensitive applications to the control end device for display, effectively solve the problem of privacy leakage, and improve the practicality of the remote control function on mobile devices.
[0050] Furthermore, in some embodiments, the above method may also include:
[0051] The style or content of the obfuscation processing is predefined based on user operations, or the style or content of the obfuscation processing is determined based on detailed information of the target application.
[0052] That is, the style or content of the blur processing can be set according to actual needs. Users can be allowed to define it in advance, so as to better meet user needs. It can also be automatically determined by the mobile device according to the detailed information of the current target application, so as to adapt to different application scenarios.
[0053] The detailed information of the target application includes the application type or application name, and the blurred style or content includes the theme, color, text or pattern, etc.
[0054] In addition, the embodiment of the present application provides a display device based on remote control of mobile phone security, which is applied to mobile phone devices. Figure 3 , the display device based on remote control mobile phone security includes:
