[0072] The embodiments of this application are described below with reference to the accompanying drawings.

[0073] The method for preventing screenshots provided in this application is applied between terminals sharing their screens. For example, Figure 1 This is a system architecture diagram provided for an embodiment of this application. Figure 1 As shown, the system may include terminal A and terminal B. Terminal A and terminal B perform screen sharing. Optionally, terminal A and terminal B have an application (APP) installed to implement screen sharing. This embodiment of the application does not limit the name or developer of the application. This embodiment of the application does not limit the number of terminals performing screen sharing. For example, three or more terminals may conduct video calls.

[0074] This application does not limit the name and type of the terminal. For example, a terminal may also be called a terminal device, electronic device, or communication device. Examples of terminals include: mobile phones, tablet computers, laptop computers, PDAs, wearable devices, etc.

[0075] For ease of explanation, this application uses the example of screen sharing between terminal A and terminal B to illustrate the embodiment.

[0076] It should be noted that the embodiments of this application do not limit the screen sharing service. For example, it may include, but is not limited to, video call service or screen projection service.

[0077] First, let's explain the screen sharing between terminal A and terminal B.

[0078] Optionally, in one implementation, Figure 2 This is a schematic diagram illustrating a terminal screen sharing embodiment provided in this application. In this implementation, terminal A and terminal B display the same screen. Figure 2 As shown, terminal A and terminal B are performing a screen sharing service, such as screen casting. Both terminal A and terminal B are displaying the relevant interface for the screen casting service in full screen. Figure 2 (a) shows display window 11 in terminal A used for displaying the screen mirroring service. Figure 2 (b) shows display window 12 in terminal B used for displaying the screen projection service. Display window 11 and display window 12 have the same layout and display the same content.

[0079] Alternatively, in another implementation, Figure 3This is another schematic diagram illustrating terminal screen sharing provided in an embodiment of this application. In this implementation, the screen layouts displayed by terminal A and terminal B are different, but they include the same shared content. Figure 3 As shown, terminal A and terminal B are engaged in a screen-sharing service, such as a video call. Both terminal A and terminal B are displaying the relevant interface for the video call in full screen. Figure 3 In (a), the display window 21 on terminal A includes window 211 and window 212. To highlight information from the other end, window 211 displays the image X captured by the camera of terminal B, and window 212 displays the image Y captured by the camera of terminal A. Figure 3 In (b) of the diagram, window 22 on terminal B includes window 221 and window 222. Similarly, to highlight information from the other end, window 221 displays the image X captured by terminal B's camera, and window 222 displays the image Y captured by terminal A's camera. In this implementation, content displayed at a certain location on one terminal's screen may be displayed at a different location on another terminal's screen. For example, for... Figure 3 When region 2121 in window 212 of (a) is mapped to terminal B, specifically: Figure 3 (b) In the region 2221 of window 222.

[0080] It should be noted that this application embodiment does not limit the position or size of the display window used for displaying screen sharing services on different terminals. Optionally, it can be displayed in full screen, for example... Figure 2 and Figure 3 As shown. Optional, it can also be displayed in a non-full-screen mode.

[0081] It should be noted that the above Figure 2 and Figure 3 This is merely an example and does not limit the screen sharing between terminal A and terminal B. Since terminal A and terminal B may have different types and screen sizes, they can have different display layouts when sharing screens.

[0082] This application provides a method for preventing screenshots, applied to terminals performing screen sharing services. One terminal sends an instruction to other terminals, instructing them to disable screenshots. Correspondingly, other terminals set their screen sharing service display windows to disable screenshots based on the instruction. The screenshot prevention method provided by this application has a simple message flow, requires few interaction messages, and achieves high efficiency in preventing screenshots. Furthermore, by displaying relevant information in the screen sharing service display window to prompt the user whether screenshots are currently disabled, the user experience is improved.

[0083] The technical solution of this application will be described in detail below through specific embodiments. The following embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments.

[0084] The terms “first,” “second,” “third,” “fourth,” etc. (if present) in the embodiments of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0085] It should be noted that in this embodiment, "screenshot" has the following meanings: obtaining a screenshot image through a screenshot operation, or obtaining a screenshot video through a screenshot operation. This embodiment does not limit the name of the screenshot; for example, it can also be called screen recording.

[0086] Figure 4 This is a flowchart illustrating a method for preventing screenshots provided in an embodiment of this application. The executing entities of this embodiment include terminal A and terminal B, and it relates to the initial establishment phase of a screen sharing service. Figure 4 As shown, the method for preventing screenshots provided in this embodiment may include:

[0087] S401. Terminal A generates a screen sharing service establishment request message. The establishment request message includes first indication information, which is used to instruct Terminal B to prohibit screenshotting.

[0088] Specifically, terminal A is the initiator of the screen sharing service, and terminal B is the recipient of the screen sharing service. When terminal A initiates the screen sharing service, it includes a first instruction in the establishment request message, instructing terminal B to prohibit screenshots.

[0089] Optionally, in one implementation, if terminal A determines that the screen sharing service is a preset service, it generates a screen sharing service establishment request message, which includes first indication information. This embodiment does not limit the preset service. For example, the preset service may include, but is not limited to, at least one of the following: video call service or screen projection service.

[0090] Optionally, in another implementation, in S401, terminal A generates an establishment request message, which may include:

[0091] Terminal A displays the screen sharing service initiation interface. This interface includes a second control used to configure whether to prevent Terminal B from taking screenshots.

[0092] Terminal A receives the user's target operation on the second control, which is used to set terminal B to prevent screenshots.

[0093] Terminal A responds to the target operation by generating an establishment request message.

[0094] For example, in combination Figure 5 This will be explained. In this example, screen sharing is a video call service. For example... Figure 5 As shown in (a), the video call service initiation interface 51 includes several functional controls, including: a "Create Contact" control, a "Save to Existing Contact" control, a "Video Call" control 52, a "Send Message" control, and a "Disable Screenshot" control 53. Control 53 is the second control, and its different display states indicate whether to disable screenshots on terminal B. When a user initiates a video call through terminal A, after entering the call number "111 1111 1111", they click control 53 to disable screenshots on terminal B. Correspondingly, terminal A responds to the user's click on control 53 by changing the display form of control 53, for example, by changing the display color. Figure 5 As shown in (b) above. The user continues to click control 52 to initiate a video call. Accordingly, terminal A responds to the user's click on control 52 by generating a setup request message, which includes first indication information.

[0095] It needs to be explained that, Figure 5 This is just an example and does not limit the interface for initiating a business.

[0096] As can be seen, in this implementation, users can set whether to block screenshots from terminal B on the service initiation interface of the screen sharing service. The operation is simple and can be set according to user needs, which improves the flexibility of setting to block screenshots from terminal B and enhances the user experience.

[0097] Optionally, to simplify user operations, the second control in the business initiation interface can be set to disable screenshots from terminal B by default.

[0098] Optionally, the request message may also include the location information of the first target area, which is the area where terminal B is prohibited from taking screenshots.

[0099] S402, Terminal A sends an establishment request message to Terminal B.

[0100] Correspondingly, terminal B receives the establishment request message sent by terminal A.

[0101] S403. Terminal B sets the screenshot attribute information of the display window of the screen sharing service according to the first instruction information.

[0102] The display window for the screen sharing service can be found in [reference needed]. Figure 2 or Figure 3 The explanations in the text will not be repeated here.

[0103] Specifically, terminal B executes the screen sharing service based on the establishment request message, and terminal B sets the screenshot attribute information of the display window of the screen sharing service according to the first instruction information. At this time, the screenshot attribute information can instruct the display window to disable screenshots.

[0104] This embodiment does not limit the specific content of the screenshot attribute information. Optionally, the screenshot attribute information includes screenshot indication information, used to indicate whether the display window prohibits screenshots. For example, the screenshot indication information is 1 bit, where a value of 1 indicates that the display window prohibits screenshots, and a value of 0 indicates that the display window allows screenshots. As another example, the screenshot indication information is 2 bits, where a value of binary 11 indicates that the entire area of ​​the display window prohibits screenshots, a value of binary 10 indicates that a portion of the display window prohibits screenshots, and a value of binary 00 indicates that the display window allows screenshots.

[0105] S404. Terminal B sends a screen sharing service establishment response message to Terminal A.

[0106] Correspondingly, terminal A receives the establishment response message sent by terminal B.

[0107] S405. Terminal A displays the first control in the screen sharing service display window. The first control is used to set whether to prohibit Terminal B from taking screenshots, and the display status of the first control indicates that Terminal B is prohibited from taking screenshots.

[0108] Specifically, terminal A executes the screen sharing service based on the establishment response message. Furthermore, it displays a first control in the screen sharing service's display window. The current display status of this first control prompts the user that terminal B is prohibited from taking screenshots, facilitating subsequent user operations and improving the user experience.

[0109] In this embodiment, the implementation method of the first control is not limited. For example, it can be a button control or a switch control.

[0110] Optional, in one example, Figure 6 This is a schematic diagram of an interface of terminal A provided in an embodiment of this application. Figure 6 As shown in (a), the display window 61 of the screen sharing service on terminal A includes a first control 62, which is a button control. The display status of the first control 62 indicates that terminal B is prohibited from taking screenshots. Figure 6 As shown in (b), the display status of the first control 62 indicates whether terminal B is allowed to take a screenshot. Different display colors of the first control indicate whether terminal B is allowed to take a screenshot.

[0111] Optionally, in another example, Figure 7 This is another schematic diagram of the interface of terminal A provided in an embodiment of this application. For example... Figure 7As shown in (a), the display window 71 of the screen sharing service on terminal A includes a first control 72, which is a toggle control. The display status of the first control 72 indicates that terminal B is prohibited from taking screenshots. Figure 7 As shown in (b), the display state of the first control 72 indicates whether terminal B is allowed to take a screenshot. Different display states of the switch control indicate whether terminal B is allowed to take a screenshot.

[0112] As can be seen, the screenshot prevention method provided in this embodiment is applied to the scenario of initial establishment of a screen sharing service by a terminal. Terminal A sends a screen sharing service establishment request message to Terminal B, which carries first indication information instructing Terminal B to prohibit screenshots. After receiving the screen sharing service establishment request message, Terminal B sets the display window of the screen sharing service to prohibit screenshots according to the first indication information, thereby preventing screenshots and protecting privacy. The screenshot prevention method provided in this embodiment has a simple message flow, a small number of interaction messages, and high efficiency in preventing screenshots. Moreover, by displaying a first control in the display window of the screen sharing service, Terminal A prompts the user that screenshots by Terminal B are currently prohibited, facilitating subsequent user operations and improving the user experience.

[0113] Optionally, after S404, it may also include:

[0114] S406. Terminal B displays a preset icon in the display window of the screen sharing service. The preset icon is used to indicate that the display window should not be screenshotted.

[0115] The display window for the screen sharing service on terminal B can be found in [reference needed]. Figure 2 or Figure 3 The relevant explanations will not be repeated here.

[0116] By displaying a preset icon in a window on terminal B, the user is prompted that terminal B or the display window prohibits screenshots, thus avoiding subsequent invalid screenshot operations by the user and improving the user experience.

[0117] It should be noted that this embodiment does not limit the position of the preset icon in the display window on terminal B, nor the pattern of the preset icon. For example, Figure 8 This is a schematic diagram of an interface of terminal B provided in an embodiment of this application. Figure 8 As shown in (a), a preset icon 82 is displayed in window 81 on terminal B.

[0118] It should be noted that this embodiment does not limit the execution order of S406 and S405.

[0119] Optionally, the method for preventing screenshots provided in this embodiment may further include, after S405:

[0120] Terminal B receives the user's second screenshot.

[0121] Terminal B responds to the second screenshot operation by generating a prompt message. The prompt message indicates that screenshots are prohibited in the displayed window.

[0122] Terminal B outputs a prompt message.

[0123] For example, in combination Figure 12 Please provide an explanation. Figure 12 This is an illustration of another interface of terminal B after a user takes a screenshot of terminal B, as provided in an embodiment of this application. Figure 12 As shown in (a), terminal B currently displays the screen sharing service display window 1201, which includes a preset icon 1202, prompting the user to disable screenshots on terminal B. If the user performs a second screenshot operation, terminal B responds to the second screenshot operation as follows: Figure 12 As shown in (b), a prompt box 1203 pops up in the display window 1201. The prompt box 1203 displays the message "Screen recording is currently disabled". The user can click the close button 1204 to close the prompt box 1203.

[0124] As can be seen, in this implementation, screenshots are currently disabled on terminal B. When a user attempts to take a screenshot, terminal B generates a notification message prompting the user to disable screenshots on terminal B, thus improving the security of disabling screenshots on terminal B.

[0125] Optionally, the method for preventing screenshots provided in this embodiment may further include, after terminal A sends an establishment request message to terminal B in S402 and before terminal A receives the establishment response message sent by terminal B in S404:

[0126] Terminal A starts the first timer.

[0127] If the first timer expires, terminal A will resend the first notification message to terminal B.

[0128] Specifically, during communication, due to changes in the communication environment, terminal B may not receive the establishment request message sent by terminal A, or terminal A may not receive the establishment response message sent by terminal B. After terminal A sends the establishment request message to terminal B, terminal A starts a first timer. In this embodiment, the value of the first timer is not limited. If the first timer expires and terminal A does not receive the establishment response message sent by terminal B, it retransmits the establishment response message to terminal B to improve the success rate of service establishment. Optionally, the maximum number of retransmissions of the establishment response message from terminal A to terminal B can be set. In this embodiment, the specific value is not limited. If terminal A receives the establishment response message sent by terminal B before the first timer expires, the first timer is stopped, and step S405 is executed.

[0129] Optionally, the display window for screen sharing on terminal A may also include a region selection control. This control is used to select a second target region, which is the area where terminal B is prohibited from taking screenshots. Following S405, it may also include:

[0130] Terminal A receives the user's second operation on the region selection control.

[0131] Terminal A responds to the user's second operation on the region selection control by receiving the user's second region selection operation in the display window.

[0132] Terminal A responds to the second area selection operation, determines the second target area, and obtains the location information of the second target area.

[0133] Terminal A sends the location information of the second target area to Terminal B. Correspondingly, Terminal B receives the location information of the second target area sent by Terminal A.

[0134] Terminal B updates the screenshot attribute information based on the location information of the second target area.

[0135] The second target area can be found in [reference]. Figure 3 Explanation of regions 2121 and 2221.

[0136] For example, in combination Figure 9 Please provide an explanation. Figure 9 This is a schematic diagram illustrating an interface change in which a user selects a prohibited screenshot area in the display window of the screen sharing service on terminal A, as provided in an embodiment of this application. Figure 9 As shown in (a), the display window 91 of the screen sharing service on terminal A includes a region selection control 92. The user can click the region selection control 92 to select a second target region. Correspondingly, in response to the user's click on the region selection control 92, terminal A updates the display state of the region selection control 92, for example, by changing its color, and waits to receive a second region selection operation from the user to continue selecting a second target region. Figure 9 As shown in (b), the user slides from position X to position Y in display window 91 (i.e., the second region selection operation), selecting the second target region 93. Correspondingly, terminal A responds to the user's second region selection operation, determining position X and position Y to obtain the location information of the second target region. After determining the second target region, the terminal can update the display format of the region selection control 92, for example, by changing the display color, such as... Figure 9 As shown in (c), this allows the user to select the area where terminal B is prohibited from taking screenshots the next time.

[0137] Optionally, in one implementation, the location information of the second target area may include the coordinates of the vertices of the display window on terminal A and the coordinates of the vertices of the second target area. In this embodiment, the number of vertices is not limited.

[0138] Optionally, in another implementation, the location information of the second target area may include the coordinates of the vertices of the second target area in a relative coordinate system, which is a coordinate system with a vertex of the display window on terminal A as the origin and the two sides containing that vertex as the coordinate axes.

[0139] As can be seen, in this implementation, the user can select a second target area to prevent terminal B from taking screenshots. Terminal A sends the location information of the second target area to terminal B. Terminal B updates its screenshot attribute information based on the received location information. At this point, the screenshot attribute information indicates that terminal B is prohibited from taking screenshots and specifies the prohibited area. Based on the location information of the second target area, terminal B can determine the area corresponding to the second target area in the screen sharing service display window on terminal B. By allowing the user to select a second target area, the user can prevent terminal B from taking screenshots in a specific area, improving the flexibility and accuracy of screenshot prevention and enhancing the user experience.

[0140] Optionally, before terminal A determines the second target area, it may also include:

[0141] The confirmation and cancel buttons are displayed in the display window.

[0142] Receive user confirmation button input.

[0143] For example, in combination Figure 10 Please provide an explanation. Figure 10 (a) and Figure 9 (b) is the same. For example Figure 10 As shown in (a), the user performs a second region selection operation in window 91 on terminal A, and then, as... Figure 10 As shown in (b), a confirm button 94 and a cancel button 95 are displayed in window 91 on terminal A. The user can click the confirm button 94 to confirm the selection of the second target area 93. Alternatively, the user can click the cancel button 95 to reselect the second target area. When the user clicks the confirm button 94, terminal A responds to the user's action by confirming the second target area.

[0144] As can be seen, by displaying the confirm and cancel buttons, terminal A allows users to further confirm whether the selected target area is correct, improving the accuracy of the selection operation and ensuring that users can reselect the target area, thus enhancing the flexibility of the operation and improving the user experience.

[0145] Optionally, after receiving the user's selection operation in the second area of ​​the display window, terminal A may further include:

[0146] Terminal A displays the boundary of the second target area in the display window.

[0147] For example, in combination Figure 9 Please provide an explanation. For example... Figure 9 As shown in (c), after the user selects the second region in the display window 91, the boundary of the second target region 93 can be continuously displayed in the display window 91, thereby prompting the user to prohibit the terminal B from taking screenshots, so as to facilitate the user's subsequent operations, such as reselecting the second target region for the user's operation.

[0148] Optionally, after updating the screenshot attribute information based on the location information of the second target area, terminal B may further include:

[0149] Terminal B displays the boundary of the area corresponding to the second target area in the display window based on the location information of the second target area.

[0150] For example, in combination Figure 3 Please provide an explanation. For example... Figure 3 As shown in (a), assume the second target area is area 2121. Based on the received location information of the second target area, terminal B can determine that the area corresponding to area 2121 in display window 22 is area 2221. Terminal B can continuously display the boundary of area 2221 in display window 22.

[0151] As can be seen, by displaying the boundary of the area corresponding to the second target area in the display window, terminal B can prompt the user about the area where terminal B is prohibited from taking screenshots, thereby avoiding unnecessary screenshot operations by the user.

[0152] Optionally, after updating the screenshot attribute information based on the location information of the second target area, terminal B may further include:

[0153] Terminal B updates the preset icons in the display window. The updated preset icons are used to indicate that screenshots are not allowed in certain areas of the display window.

[0154] For example, in combination Figure 8 Please provide an explanation. For example... Figure 8 As shown in (a), the window 81 on terminal B includes a preset icon 82, used to indicate that terminal B is prohibited from taking screenshots. After terminal B updates the screenshot attribute information according to the location information of the second target area, as shown in (a), Figure 8 As shown in (b), the preset icon 82 is updated to the preset icon 83. The preset icon 83 is used to indicate that terminal B is prohibited from taking screenshots of a portion of the display window.

[0155] Optionally, after updating the screenshot attribute information based on the location information of the second target area, terminal B may further include:

[0156] Terminal B receives the user's first screenshot.

[0157] Terminal B responds to the first screenshot operation by taking a screenshot and generating a screenshot image based on the screenshot attribute information. The area in the screenshot image that corresponds to the second target area is a preset fill pattern.

[0158] For example, in combination Figure 11 Please provide an explanation. Figure 11 This is a schematic diagram of the interface of terminal B after a user takes a screenshot of terminal B, as provided in an embodiment of this application. Figure 11 As shown in (a), terminal B currently displays a screen sharing service display window 1101. Display window 1101 includes a preset icon 1102, prompting the user to prohibit terminal B from taking screenshots of certain areas within the display window. If the user performs a first screenshot operation, terminal B responds by determining that screenshotting is currently prohibited based on the screenshot attribute information of display window 1101, and terminal B can then take a screenshot and generate a screenshot image. However, the area in the screenshot image corresponding to the second target area is filled with a preset pattern. For example, as shown... Figure 11 As shown in (b) of the screenshot, area 1104 in the screenshot image 1103 is filled with shadow.

[0159] It should be noted that this embodiment does not limit the implementation method of the preset fill pattern.

[0160] As can be seen, in this implementation, screenshots by terminal B are currently prohibited. Even if the user takes a screenshot and terminal B generates a screenshot image, the area in the screenshot image that is prohibited from being screenshotted is filled with a preset fill pattern, protecting privacy and effectively preventing terminal B from taking screenshots, thus improving the security of preventing terminal B from taking screenshots.

[0161] Optionally, the method for preventing screenshots provided in this embodiment may further include, after S405:

[0162] Terminal A receives a second operation from the user on the first control. This second operation on the first control is used to set whether Terminal B is allowed to take screenshots.

[0163] In response to the user's second operation on the first control, terminal A generates a second notification message. The second notification message includes second instruction information, which instructs terminal B to take a screenshot.

[0164] Terminal A sends a second notification message to Terminal B. Correspondingly, Terminal B receives the second notification message sent by Terminal A.

[0165] Terminal B updates the screenshot attribute information of the display window of the screen sharing service according to the second instruction information.

[0166] Terminal B sends a second response message to terminal A. Correspondingly, terminal A receives the second response message sent by terminal B.

[0167] For example, in combination Figure 6 Please provide an explanation. For example... Figure 6 As shown in (a), the display window 61 on terminal A includes a first control 62. The display state of the first control 62 indicates that terminal B is prohibited from taking screenshots. The user can click the first control 62 to allow terminal B to take screenshots. Correspondingly, in response to the user clicking the first control 62, terminal A updates the display state of the first control 62, for example, by changing the display color. Figure 6 As shown in (b) above, Terminal A sends a second notification message to Terminal B. Correspondingly, Terminal B receives the second notification message sent by Terminal A. Terminal B updates its screenshot attribute information according to the second indication information in the second notification message. At this time, the screenshot attribute information indicates that Terminal B is allowed to take a screenshot.

[0168] In this implementation, users can set terminal B to allow screenshots, which improves the flexibility of operation.

[0169] Optionally, if terminal B displays a preset icon in the screen sharing service display window, then the display of the preset icon will be stopped.

[0170] By stopping the display of preset icons, the system prompts the user that screenshots are currently allowed on terminal B, facilitating subsequent user operations.

[0171] Optionally, after terminal A sends the second notification message to terminal B and before terminal A receives the second response message sent by terminal B, the process may further include:

[0172] Start the second timer.

[0173] If the second timer expires, the second notification message will be resent to terminal B.

[0174] The technical principle of the second timer is similar to that of the first timer mentioned above, and will not be repeated here.

[0175] Figure 13 This is another flowchart illustrating a method for preventing screenshots provided in this application. The executing entities in this embodiment include terminal A and terminal B, and it involves a scenario where terminal A and terminal B have already executed a screen sharing service and are sharing their screens. A first control is displayed in the screen sharing service display window on terminal A, and the display status of the first control indicates that terminal B is allowed to take a screenshot. For example... Figure 13 As shown, the method for preventing screenshots provided in this embodiment may include:

[0176] S1301. Terminal A receives the user's first operation on the first control. The first operation on the first control is used to set terminal B to be prohibited from taking screenshots.

[0177] S1302, Terminal A responds to the user's first operation on the first control and generates a first notification message. The first notification message includes first instruction information, which is used to instruct Terminal B to prohibit screenshotting.

[0178] S1303, Terminal A sends a first notification message to Terminal B. Correspondingly, Terminal B receives the first notification message sent by Terminal A.

[0179] S1304. Terminal B sets the screenshot attribute information of the display window of the screen sharing service according to the first instruction information.

[0180] S1305, Terminal B sends a first response message to Terminal A. Correspondingly, Terminal A receives the first response message sent by Terminal B.

[0181] S1306. Terminal A displays a first control in the display window of the screen sharing service. The first control is used to set whether to prohibit Terminal B from taking screenshots. The display status of the first control indicates that Terminal B is prohibited from taking screenshots.

[0182] The following is combined Figure 14 An example is provided. Figure 14 As shown in (a), the display window 1401 for screen sharing on terminal A includes a first control 1402, which is a button control. The display state of the first control 1402 indicates whether terminal B is allowed to take a screenshot. The user can click the first control 1402 to disable screenshots on terminal B. Correspondingly, in response to the user clicking the first control 1402, terminal A updates the display state of the first control 1402, for example, by adjusting the display color. Figure 14 As shown in (b) above, Terminal A sends a first notification message to Terminal B. Correspondingly, Terminal B receives the first notification message from Terminal A. Terminal B sets the screenshot attribute information of the display window for the screen sharing service on Terminal B according to the first instruction information in the first notification message. At this time, the screenshot attribute information indicates that Terminal B is prohibited from taking screenshots.

[0183] As can be seen, in the screenshot prevention method provided in this embodiment, the terminal has already executed the screen sharing service and is currently sharing the screen. User operation triggers terminal A to send a first notification message to terminal B, which carries first instruction information instructing terminal B to prohibit screenshots. After receiving the first notification message, terminal B sets the display window of the screen sharing service to prohibit screenshots according to the first instruction information, thereby preventing screenshots and protecting privacy. The screenshot prevention method provided in this embodiment has a simple message flow, a small number of interaction messages, and high efficiency in preventing screenshots. Moreover, terminal A displays a first control in the display window of the screen sharing service to prompt the user that screenshots by terminal B are currently prohibited, facilitating subsequent user operations and improving the user experience.

[0184] Optionally, the method for preventing screenshots provided in this embodiment may further include, after step S1305:

[0190] Terminal A starts the first timer.

[0191] If the first timer expires, terminal A will resend the first notification message to terminal B.

[0192] The first timer can be referred to in the relevant description of the first timer in the aforementioned embodiment, and the principle is similar, so it will not be repeated here.

[0193] Optionally, the first notification message may also include location information of the first target area, where the first target area is the area where terminal B is prohibited from taking screenshots. Correspondingly, in S1304, terminal B sets the screenshot attribute information of the display window of the screen sharing service according to the first instruction information, which may include:

[0194] Terminal B sets the screenshot attribute information of the display window of the screen sharing service according to the first instruction information and the location information of the first target area.

[0195] Optionally, the window displayed on terminal A may further include a region selection control, which is used to select a first target region. The method for preventing screenshots provided in this embodiment may further include:
