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 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.
The flow diagrams depicted in the figures are merely illustrative and do not necessarily include all of the elements and operations/steps, nor do they necessarily have to be performed in the order depicted. For example, some operations/steps may be decomposed, combined or partially combined, so that the actual execution order may be changed according to the actual situation.
In the following description, suffixes such as "module", "component", or "unit" used to denote elements are used only for the convenience of description of the present application, and have no peculiar meaning by themselves. Thus, "module", "component" or "unit" may be used mixedly.
Referring to fig. 1, fig. 1 is a schematic flowchart illustrating an embodiment of a method for restricting screen sharing according to the present application. The method includes step S11, step S12, step S13, and step S14.
Step S11: the first terminal and the second terminal establish a video call.
When the first terminal passively receives a video call request of the second terminal or when the first terminal actively sends the video call request to the second terminal, the first terminal and the second terminal establish a video call.
Step S12: and the first terminal executes corresponding operation and/or determines a screen area capable of being collected according to the screen sharing request of the second terminal and the screen sharing limit requirement preset by the first terminal.
In video conferencing, online classroom, live game, etc., screen sharing is one of the most common functions. The screen sharing may be a real-time sharing of the screen.
The screen sharing request may be sent together with the video call request when the second terminal sends the video call request to the first terminal, or may be sent to the first terminal during the video call.
The preset screen sharing restriction requirement may refer to a restriction requirement for screen sharing that is preset by the first terminal, including but not limited to: an area that can be shared during screen sharing, an area that cannot be shared during screen sharing, an application that can be shared during screen sharing, an application that cannot be shared during screen sharing, an application that needs to be hidden during screen sharing, an application that needs to turn off a notification function during screen sharing, an application that prohibits remote access during screen sharing, and the like.
The screen sharing restriction requirement may be a combined restriction requirement of two or more of the above restriction requirements. For example: the screen sharing restriction requirements include an area that can be shared at the time of screen sharing and an application that can be shared at the time of screen sharing. Another example is: the screen sharing restriction requirements include an application program that needs to be hidden at the time of screen sharing and an application program that needs to turn off the notification function at the time of screen sharing. For another example: the screen sharing restriction requirements include an area that can be shared at the time of screen sharing, an application program that needs to close the notification function at the time of screen sharing, and an application program that prohibits remote access at the time of screen sharing.
The screen sharing restriction requirement can be flexibly set according to the requirements of the user, can also be automatically set by the system, or can be additionally set by the user according to the requirements of the user on the basis of automatic setting of the system.
When a screen sharing request of a second terminal is received, the first terminal executes corresponding operation to meet the screen sharing restriction requirement in combination with a screen sharing restriction requirement preset by the first terminal, and/or the first terminal determines a screen area capable of being collected to meet the screen sharing restriction requirement, so that the first terminal can be prevented from being presented to the second terminal without reservation, and privacy safety during screen sharing of the first terminal can be effectively improved.
Step S13: and acquiring screen data of the first terminal according to the screen area and/or the screen area capable of being acquired after the first terminal executes corresponding operation.
Step S14: and the first terminal sends the screen data to a second terminal, so that the second terminal displays according to the screen data.
Screen capture (i.e., screen recording) is the basis for implementing screen sharing. Generally, when a real-time screen is shared, a sharing initiator captures a picture of a specified source in the screen at a fixed sampling frequency, and distributes the picture at a corresponding frame rate on a real-time network after video coding and compression.
According to the embodiment of the application, a first terminal and a second terminal establish a video call; according to the screen sharing request of the second terminal and the screen sharing limit requirement preset by the first terminal, the first terminal executes corresponding operation and/or determines a screen area capable of being collected; acquiring screen data of the first terminal according to a screen area and/or a screen area which can be acquired after the first terminal executes corresponding operation; and the first terminal sends the screen data to a second terminal, so that the second terminal displays according to the screen data. Due to the fact that the screen sharing limit requirement is preset, when the screen sharing request of the second terminal is received, the screen sharing limit requirement is preset, the first terminal performs corresponding operation and/or determines a screen area capable of being collected, then collects screen data of the first terminal and sends the screen data to the second terminal, and therefore the first terminal can be prevented from being displayed to the second terminal without reservation, and privacy safety of the first terminal during screen sharing can be effectively improved.

In this embodiment, the screen sharing restriction requirement includes a fourth preset application program that prohibits remote access during screen sharing, and when the screen sharing request includes an instruction for starting the specified application program, it is necessary to determine whether the specified application program belongs to an application program in the fourth preset application program that prohibits remote access, and if so, it is necessary to prohibit access by the second terminal, so that the instruction is discarded and not executed; if not, the instruction can be executed, and the first terminal starts the specified application program. And after the first terminal discards the instruction or starts the specified application program, all areas on the first terminal can be collected.
The method of the embodiment of the application can be used by being combined with a special video call application program, and can also be directly used by being combined with a video call function of the terminal. If the terminal is used in combination with a special video call application program, a user needs to download and install the corresponding application program, and the video call function of the terminal is basically the standard configuration of each terminal. Therefore, in an embodiment, the method of the embodiment is directly combined with a video call function of a terminal for use, and a user can effectively improve privacy security during screen sharing without downloading and installing a special application program. In practical application, the first terminal may display a "screen sharing privacy protection" switch on a setting menu and a call interface, and turn on the switch to indicate that the method of this embodiment needs to be implemented to implement the screen sharing privacy protection.
The channels of a video call typically transmit limited types of data, such as audio and video, and cannot transmit data types such as pictures, data links, and the like. Therefore, when the method of the embodiment is used in combination with the video call function of the terminal, the data channel is established, and the acquired screen data is transmitted through the data channel, so that more data types of data can be transmitted.
In an embodiment, in step S12, before the first terminal performs a corresponding operation and/or determines a screen area capable of being collected according to the screen sharing request of the second terminal and the screen sharing restriction requirement preset by the first terminal, the method may further include: and step S15.

At this time, in step S14, the sending, by the first terminal, the screen data to the second terminal may include: and the first terminal sends the screen data to a second terminal through the data channel.
The 5G new call solution is used as a call service enhancement mode realized based on an IP Multimedia Subsystem (IMS) data channel architecture, has the characteristics of high definition, visualization and interactivity, and can effectively improve the call experience of users in the 5G era. The 5G new call solution realizes service scenes such as multimedia caller identification, visual menus, screen sharing, AR marks and the like, not only upgrades the call experience of individual users, but also brings new capability of fitting with an industry communication scene to industry users. In one embodiment, the data channel establishment request is carried in a video call request; at this time, in step S15, the establishing, by the first terminal, a data channel according to the data channel establishment request of the second terminal may include: monitoring Session Initiation Protocol (SIP) signaling of the second terminal, analyzing a dcmap field in a Session Description Protocol (SDP) offer message in the Session Initiation Protocol signaling, and establishing a data channel for the first terminal.
According to the 3GPP TS26.114 specification, the dcmap field characterizes the need to establish a data channel. The data channel may be a boottrap data channel, which is a data channel with a Stream ID less than 1000, and is used for a terminal to obtain a hypertext Markup Language (HTML) webpage, that is, a data channel application defined in the 3gpp ts26.114 specification, from a network side, where the application generally includes HTML, javaScript, cascading Style Sheets (CSS), and the like. The data channel may also be a non-boottrap data channel, which is used to transmit data information required by the data channel application.
