Abstract
Description
Technical Field
[0001] This invention relates to the field of intelligent interactive technology, and in particular to a privacy-preserving screen projection method, system, terminal, and storage medium. Background Technology
[0002] Existing screen mirroring solutions involve sharing the entire screen of a mobile device with the receiving device in real time, such as displaying the phone screen on a large screen device like a TV or projector. Using screen mirroring solutions can enhance the user's immersive experience through large screen devices and also meet the needs of multi-person scenarios.
[0003] However, in multi-person scenarios such as meetings, users may need to perform private operations such as opening emails or checking WeChat messages during the sharing process. To protect their privacy, users usually need to disconnect the current screen-sharing device, handle emails and messages, and then search for and re-share the screen-sharing device. This operation is very cumbersome, and the loss of screen due to interruption can also affect the continuation of the meeting.
[0004] Existing privacy-preserving screen mirroring methods typically involve establishing a whitelist of applications. By detecting whether the target application being switched to during screen mirroring is a whitelisted application, the necessary screen signal transmission is only retained for whitelisted applications. This prevents private content from being immediately displayed on the screen mirroring device when switching applications. However, this solution is based on the established application whitelist and does not take into account the needs of users in different scenarios, thus failing to prioritize the user.
[0005] Existing technologies still have the problem that privacy-focused screen mirroring methods are not user-driven, therefore, existing technologies need further improvement. Summary of the Invention

The privacy screen mirroring module is used to create a first button on the first device, and to switch the first device from a non-privacy state to a privacy state by pressing the first button, while retaining the current frame of the first device.
[0015] Thirdly, the present invention provides a terminal, including: a processor and a memory, wherein the memory stores a privacy screen casting program, and the privacy screen casting program, when executed by the processor, is used to implement the privacy screen casting method as described in the first aspect.

[0024] The objectives, features, and advantages of this invention will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation
[0025] To make the objectives, technical solutions, and advantages of this invention clearer and more explicit, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
[0026] Exemplary methods Existing privacy-preserving screen mirroring methods typically involve establishing a whitelist of applications. By detecting whether the target application being switched to during screen mirroring is a whitelisted application, the necessary screen signal transmission is only retained for whitelisted applications. This prevents private content from being immediately displayed on the screen mirroring device when switching applications. However, this solution is based on the established application whitelist and does not take into account the needs of users in different scenarios, thus failing to prioritize the user.
[0027] To address the above technical issues, this invention provides a privacy-focused screen mirroring method, system, terminal, and storage medium, comprising: acquiring all screen-mirroring devices within a preset range for a first device; selecting a second device from the acquired screen-mirroring devices and establishing a connection between the first device and the second device through a first screen mirroring protocol; setting the first device to a non-privacy state and transmitting the screen of the first device to the second device for synchronous display; creating a first button on the first device and switching the first device from a non-privacy state to a privacy state via the first button, while retaining the current frame of the first device; this invention enables user-driven switching of the device from a non-privacy state to a privacy state via the first button, retaining the current frame of the first device when switching to a privacy state, and preventing the privacy state switch during screen mirroring from affecting the task progress.
[0028] like Figure 1 As shown, this embodiment of the invention provides a privacy-focused screen mirroring method, including the following steps: Step S100: Obtain all screen-projectionable devices within a preset range for the first device.
[0029] It should be noted that the first device is the initiator of screen mirroring, i.e., the active screen mirroring device. When screen mirroring, the screen of the first device will be transmitted to the screen-sharing device for synchronous display. The active screen mirroring device is generally a mobile terminal, such as a smartphone, tablet, laptop or other device that supports screen mirroring.
[0030] In this embodiment, the first device is a transmitting device, used to send the screen of the device to the device to be projected for display. The transmitting device and the device to be projected can be connected by wired transmission or wireless transmission. The transmitted content is mainly the real-time screen of the transmitting device; for example, wired transmission connection through HDMI direct connection, VGA connection, USB-C to HDMI converter, etc.; or wireless transmission connection through Bluetooth, Wi-Fi, etc.
[0031] In this embodiment, the preset range is determined by the first device itself and the connection method used. For example, when the first device uses wired transmission, the preset range is the range of the transmission medium used for wired transmission, and the other end of the transmission medium needs to be connected to the screen-casting device in advance. When the first device is a mobile phone and uses Bluetooth as a wireless transmission connection method, its preset range for searching for screen-casting devices is the maximum range that it can establish a connection through Bluetooth, but the signal transmission quality is generally poor in this maximum range. When the first device is a mobile phone and uses Wi-Fi as a wireless transmission connection method, its preset range for searching for screen-casting devices is the maximum connection range supported by the Wi-Fi it is connected to. Screen-casting devices connected to the same Wi-Fi can all be considered as screen-casting devices within its preset range.
[0032] like Figure 1 As shown, this embodiment of the invention provides a privacy-focused screen mirroring method, including the following steps: Step S200: Select a second device from the acquired screen-casting devices, and establish a connection between the first device and the second device through the first screen-casting protocol.
[0033] In this embodiment, the first screen casting protocol is a privacy screen casting protocol, which adds privacy screen casting functionality to the ordinary protocol. Therefore, before using this protocol to connect the first device and the second device, the user needs to actively confirm and select it. The first screen casting protocol is only enabled when the user selects the privacy screen casting mode.
[0034] Specifically, in one implementation of this embodiment, step S200 includes the following steps: Step S201: Select the second device from the acquired screen-castable devices.
[0035] In this embodiment, the second device is the target projection device. The user's desired target projection device is selected from all available projection devices. Provided the second device is a projection-capable device, the size and type of the target projection device are not limited. For example, the first device can project onto a second device with a smaller screen; it can also project onto a second device with a larger screen; it can project onto a second device of the same type as the first device; or it can project onto a second device of a different type than the first device.
[0036] Step S202: Select the screen mirroring mode of the first device.
[0037] In this embodiment, the screen casting modes of the first device include a privacy screen casting mode and a non-privacy screen casting mode. The privacy screen casting mode is the screen casting mode used by the privacy screen casting method. In this mode, a first screen casting protocol is used, which is the privacy screen casting protocol. The non-privacy screen casting mode is the regular screen casting mode. In this mode, a second screen casting protocol is used, which is the regular screen casting protocol.
[0038] In this embodiment, the screen mirroring mode of the first device is selected as follows: before establishing the connection between the first device and the second device, the user is prompted to select a screen mirroring mode via a pop-up window or other means. The user can choose the screen mirroring mode according to the environment of the current screen mirroring. For example, in a scenario where the user is mirroring alone, a non-privacy screen mirroring mode can be selected, and the connection between the first device and the second device can be established through a conventional screen mirroring protocol; when the user is in a multi-person scenario such as a meeting, a privacy screen mirroring mode can be selected, and the connection between the first device and the second device can be established through a privacy screen mirroring protocol to protect personal privacy.
[0039] Step S203: When the selected screen casting mode is privacy screen casting mode, a connection is established between the first device and the second device through the first screen casting protocol.
[0040] In this embodiment, when the selected screen casting mode is privacy screen casting mode, a connection is established between the sending device and the target screen casting device through the privacy screen casting protocol.
[0041] In one implementation of the present invention, the screen mirroring connection status of the sending device can be marked or reminded, so that users can determine whether the sending device that initiated the screen mirroring is in a privacy screen mirroring state by checking the screen mirroring connection status of the sending device.
[0042] Step S204: When the selected screen casting mode is non-privacy screen casting mode, a connection is established between the first device and the second device through the second screen casting protocol.
[0043] In this embodiment, when the selected screen casting mode is the non-privacy screen casting mode, a connection is established between the sending device and the target screen casting device through the conventional screen casting protocol. After the connection is established, the sending device will not trigger the selection of screen casting mode again during this screen casting process.
[0044] like Figure 1 As shown, this embodiment of the invention provides a privacy-focused screen mirroring method, including the following steps: Step S300: Set the first device to a non-privacy state and transmit the screen of the first device to the second device for synchronous display.
[0045] In this embodiment, after establishing a connection between the sending device and the target device, the first device is set to a non-privacy state, and the screen of the sending device is transmitted to the target projection device for synchronous display, thereby realizing the projection display of the sending device on the target projection device.
[0046] It should be noted that in this embodiment, the non-privacy state refers to the state of the sending device when the user selects the privacy casting mode, in which the user has not made any privacy settings. For example, when privacy casting mode is enabled, this refers to non-privacy operations performed by the user on the target casting device using the sending device. Similarly, the privacy state also refers to the state of the sending device when the user selects the privacy casting mode.
[0047] like Figure 2 The diagram shows a first device and a corresponding second device in a non-privacy state in one implementation of the present invention. The device on the left is the second device, i.e., the target projection device, and the screen displayed in the center of the target projection device is the real-time screen of the current sending device. The device on the right is the first device, i.e., the sending device, and the lock button is located in the middle of the right side of the sending device.
[0048] like Figure 1 As shown, this embodiment of the invention provides a privacy-focused screen mirroring method, including the following steps: Step S400: Create a first button on the first device, switch the first device from a non-private state to a private state by pressing the first button, and retain the current frame of the first device.
[0049] In this embodiment, the first button is a lock button. After the lock button is activated / triggered, the sending device is first switched from a non-private state to a private state. The target screen-casting device will retain the last frame of the sending device and then pause the screen transmission between the sending device and the target screen-casting device. By retaining the last frame of the sending device, the user's privacy is prevented from being leaked.
[0050] It should be noted that the lock button created on the transmitting device is a virtual button, not a real button. Virtual buttons are easy to adjust, change, and switch. For example, in this embodiment, the lock button can be switched to the unlock button of the transmitting device in privacy mode. The unlock button has the same button attributes as the lock button; the only difference between the two is in function and appearance.
[0051] Specifically, in one implementation of this embodiment, step S400 includes the following steps: Step S401: When the first device is in a non-privacy state, trigger the first button to switch the first device to a privacy state.
[0052] In this embodiment, the lock button is only displayed when the sending device is in a non-privacy state. The lock button is used to switch the first device from a non-privacy state to a privacy state when triggered, lock the last frame of the screen at the trigger time, and pause the screen transmission between the sending device and the target projection device.
[0053] Step S402: Retain the current frame of the first device on the second device.
[0054] In this embodiment, the current frame is the last frame of the device sent when the lock button is triggered.
[0055] Step S403: Pause the image transmission between the first device and the second device.
[0056] In this embodiment, while the target projection device in privacy mode retains the current frame of the sending device, it pauses the transmission of images between the sending device and the target projection device. At this time, until the user switches the sending device to non-privacy mode, the content displayed on the target projection device is the current frame of the sending device switching to privacy mode. The operation of the sending device will not be projected onto the target projection device, which can effectively protect user privacy.
[0057] like Figure 3 The diagram shows a first device and a corresponding second device in a privacy state according to one implementation of the present invention. The device on the left is the second device, i.e., the target screen projection device, and the screen displayed in the center of the target screen projection device is the current frame / last frame of the sending device. The device on the right is the first device, i.e., the sending device, and the unlock button is located in the middle of the right side of the sending device.
[0058] In this embodiment, a convenient locking method is provided by using a lock button. The last frame of the sending device is retained first, which can not only prevent privacy leakage when the user switches privacy status, but also prevent the user from being unable to continue the screen projection content before the screen transmission was interrupted after reconnection. The task process will not be affected by the privacy status switch during screen projection.
[0059] like Figure 1 As shown, this embodiment of the invention provides a privacy-focused screen mirroring method, including the following steps: Step S500: When the first device is in a privacy state, the first button is converted to a second button, and the first device in the privacy state is switched to a non-privacy state by using the second button.
[0060] In this embodiment, when the transmitting device is in a privacy state, the lock button is converted into an unlock button. The unlock button is located in the same position as the lock button. The transmitting device in the privacy state is switched to a non-privacy state by using the unlock button.
[0061] Specifically, in one implementation of this embodiment, step S500 includes the following steps: Step S501: When the first device is in a privacy state, the second button is triggered.
[0062] In this embodiment, when the transmitting device is in a privacy state, the lock button of the transmitting device is converted into an unlock button. By activating / triggering the unlock button, the transmitting device is switched from a privacy state to a non-privacy state.
[0063] Step S502: Switch the first device to a non-privacy state and restore the image transmission between the first device and the second device.
[0064] In this embodiment, after the unlock button is activated / triggered, the sending device switches to a non-privacy state. The target screen projection device will first restore the screen transmission between the sending device and the target screen projection device, and then switch the current frame screen to the real-time screen of the sending device.
[0065] In this embodiment, a waiting time can also be set. When the transmitting device switches to a non-privacy state, the current frame is switched to the real-time frame of the transmitting device after the waiting time has elapsed. This ensures that the user can end the current privacy operation if the transmitting device is switched to a non-privacy state before the privacy operation is completed. For example, if the waiting time is set to 5 seconds, the user can end the privacy operation in a timely manner.
[0066] In one implementation of the present invention, a privacy-based screen casting method is implemented by pre-setting a privacy application for the first device, comprising the following steps: Step a: Pre-configure the privacy application on the first device.
[0067] In this embodiment, privacy applications on the sending device are pre-defined. For example, applications containing user privacy, such as social media, email, and banking apps, are designated as privacy applications. By setting privacy applications, users can be specifically reminded when they forget to actively enter privacy mode.
[0068] In this embodiment, the privacy application can be configured online or by actively setting the application name / type. The set privacy application corresponds to the privacy screen casting protocol and is only applied to the sending device when the screen casting mode is privacy screen casting mode.
[0069] Step b: When the first device is in a non-privacy state, monitor the activation status of the privacy application.
[0070] In this embodiment, the activation status of privacy applications is monitored in real time only when the sending device is in a non-privacy state. This avoids unnecessary power consumption caused by continuous monitoring occupying the sending device's memory when the user does not need privacy operations or the user has already entered a privacy state.
[0071] In this embodiment, when the transmitting device is in a non-privacy state, before the user is detected to have enabled the privacy application, the user's direct access to the privacy application can be delayed by retaining the application's launch page, in order to avoid leakage of user privacy, and the user is prompted whether to switch the privacy state.
[0072] Step c: When the privacy application is enabled, the first button is highlighted.
[0073] In this embodiment, when the sending device is in a non-privacy state, if the user is detected to have enabled a privacy application, the lock button is highlighted. For example, the lock button can be highlighted by making the background of the lock button red, enlarging the lock button, or changing the lock button to a small-amplitude movement state, so as to remind the user that the current state is non-privacy. The screen of the sending device will be transmitted in real time and displayed on the target projection screen.
[0074] like Figure 4 The diagram shows a first device and a corresponding second device in a non-privacy state and entering a privacy application in one implementation of the present invention. The device on the left is the second device, i.e., the target screen projection device, and the screen displayed in the center of the target screen projection device is the real-time screen of the sending device. The device on the right is the first device, i.e., the sending device, and the lock button in the middle of the right side of the sending device is highlighted in red.
[0075] This embodiment achieves the following technical effects through the above technical solution: This embodiment selects the screen casting mode of the sending device. Only when the sending device selects the privacy screen casting mode, a connection is established between the sending device and the target screen casting device through the privacy screen casting protocol. This allows the user to have the right to choose the privacy screen casting method, making it user-driven and convenient for users to make different decisions in different screen casting scenarios. By using the created lock button, a convenient locking method is provided; when switching the sending device from non-private state to private state, the last frame of the sending device is retained first, which can not only avoid privacy leakage when switching the private state, but also prevent the user from being unable to continue the screen projection content before the screen transmission was interrupted after reconnection. The task process will not be affected by the privacy state switching during screen projection. When the sending device switches from privacy mode to non-privacy mode, a waiting time can be set. After the waiting time, the current frame is switched to the real-time frame of the sending device. This ensures that the user can end the current privacy operation before switching the sending device to non-privacy mode. Furthermore, by pre-setting privacy applications, users can be specifically reminded when they forget to actively enter privacy mode. Moreover, the activation status of privacy applications will only be monitored in real time when the sending device is in non-privacy mode. This avoids unnecessary power consumption caused by continuous monitoring occupying the sending device's memory when the user does not need privacy operations or has already entered privacy mode. By highlighting the lock button, the user can also be reminded that they are currently in non-privacy mode. The screen of the sending device will be transmitted in real time and displayed on the target screen.
