Description

Technical Field

[0001] This application relates to the field of communications, and more particularly to a secure display method and electronic device. Background Technology

[0002] To facilitate user communication, users can share the interface of their electronic devices with other users through screenshots, screen recordings, screen sharing, and screen mirroring. However, sharing the interface through these methods may involve copyright issues or leak user privacy. Typically, to avoid leaking their own or others' privacy, users can use editing tools to blur or mosaic sensitive information before sending it. However, this method is cumbersome and provides a poor user experience. Summary of the Invention

[0003] This application provides a secure display method and electronic device that can improve user experience while protecting user privacy information.

[0004] To achieve the above objectives, the embodiments of this application adopt the following technical solutions:

[0005] A first aspect of this application provides a secure display method, comprising: a first electronic device displaying a first image; the first electronic device receiving a first operation from a user, the first operation being used to acquire the first image displayed by the first electronic device; in response to the user's first operation, if the first electronic device determines that a first layer in the first image includes a security identifier, the first electronic device replaces or overwrites the first layer with a first preset layer, and generates a second image. Based on this solution, when the first electronic device determines that a layer in the first image includes a security identifier, by replacing or overwriting the layer containing the security identifier with a first preset layer, the generated second image does not display the layer containing the security identifier, thus protecting the user's privacy or copyright. Furthermore, this solution does not require user editing to generate a second image that does not display user privacy or copyright, thus improving the user experience.

[0006] Understandably, when the first electronic device uses a first preset layer to cover the first layer, it can composite multiple layers of the first image with the first preset layer. During this composite process, the first preset layer is positioned above the first layer, allowing the first layer to be covered by it. Although the generated second image still includes the first layer, because it is covered by the first preset layer, the generated second image does not display the first layer; that is, the first layer is invisible to the user. This ensures that the generated second image does not display user privacy information or copyright information.

[0007] Optionally, the first image may be the entire image displayed on the screen of the first display device, or it may be a partial image displayed on the screen of the first electronic device.

[0008] Optionally, the security identifier mentioned above can be pre-configured by a third-party application or system. For example, a third-party application can pre-configure a security identifier for layers involving user privacy information. As another example, a third-party application can pre-configure a security identifier for layers involving copyright. Optionally, the security identifier can be LayoutParams.FLAG_SECURE.

[0009] In conjunction with the first aspect, in one possible implementation, the first electronic device replaces the first layer with a first preset layer and generates a second image, including: the first electronic device replacing the first layer with the first preset layer; the first electronic device combining the second layer in the first image with the first preset layer to generate the second image; the second layer does not include the security identifier. Based on this solution, when generating the second image, the first electronic device replaces the first layer in the first image with the first preset layer, and then combines the second layer in the first image (excluding the security identifier) ​​with the first preset layer to obtain the second image. Therefore, the generated second image no longer includes the first layer, thereby protecting copyright if the first layer involves copyright, and protecting user privacy if the first layer includes user privacy information.

[0010] In conjunction with the first aspect and the aforementioned possible implementations, in another possible implementation, the first preset layer includes a prompt message indicating that the first image contains security information. Based on this solution, the prompt message in the first preset layer allows the user to understand why the second image differs from the first image, thus improving the user experience.

[0011] Optionally, the prompt information in the first preset layer can be text information such as "Safe interface prohibits screenshots" or "Safe interface prohibits screen recording", or it can be an animated or icon prompt. This application does not limit the specific content and type of the prompt information.

[0012] In conjunction with the first aspect and the aforementioned possible implementations, in another possible implementation, the first operation includes a screenshot operation, a screen recording operation, a screen casting operation, or a screen sharing operation. Based on this solution, when the first electronic device receives a user's screenshot operation, screen recording operation, screen casting operation, or screen sharing operation, in response to the operation, the first electronic device further determines whether the first layer in the first image includes a security identifier. If the first electronic device determines that the first layer in the first image includes a security identifier, the first electronic device replaces or covers the first layer with a first preset layer and generates a second image, thereby ensuring that the layer containing the security identifier is not displayed in the generated second image, thus protecting the user's privacy or copyright.

[0013] In conjunction with the first aspect and the aforementioned possible implementations, in another possible implementation, when the first operation is a screenshot or screen recording operation, the method further includes: the first electronic device displaying the second image. Based on this solution, when the user input operation is a screenshot or screen recording operation, the first electronic device replaces or overwrites the first layer in the first image to generate a second image, and displays the processed second image on the display screen. It is understood that the second image displayed by the first electronic device does not involve copyright or privacy information, thus protecting the user's privacy or copyright.

[0014] In conjunction with the first aspect and the aforementioned possible implementations, in another possible implementation, when the first operation is a screen mirroring operation or a screen sharing operation, the method further includes: the first electronic device sending the second image to the second electronic device. Based on this solution, when the user input operation is a screen mirroring operation or a screen sharing operation, the first electronic device replaces or overwrites the first layer in the first image to generate a second image, and sends the second image to the second electronic device. Upon receiving the second image, the second electronic device can display it. Therefore, in screen mirroring or screen sharing scenarios, the second image displayed by the second electronic device is different from the first image displayed by the first electronic device, thereby ensuring that security information is not leaked.

[0015] In conjunction with the first aspect and the aforementioned possible implementations, in another possible implementation, the method further includes: the first electronic device receiving a second operation from a user, the second operation being used to activate a security switch control; in response to the user's second operation, the electronic device filtering a third layer in the second image to generate a third image; the third layer including pop-up notification information. Based on this solution, by activating the security switch control, the pop-up notification information of the first electronic device can be further filtered, thereby preventing other users from seeing user SMS notifications or application notifications, thus better protecting user privacy.

[0016] In conjunction with the first aspect and the aforementioned possible implementations, in another possible implementation, when the first operation is a screenshot or screen recording operation, the method further includes: the first electronic device displaying the third image. Based on this solution, when the user input operation is a screenshot or screen recording operation, the first electronic device displays the processed third image on the display screen. It is understood that the third image displayed by the first electronic device does not involve copyright or privacy information and does not include pop-up prompts, thus better protecting the user's privacy or copyright.

[0017] In conjunction with the first aspect and the aforementioned possible implementations, in another possible implementation, when the first operation is a screen mirroring operation or a screen sharing operation, the method further includes: the first electronic device sending the third image to the second electronic device. Based on this solution, when the user input operation is a screen mirroring operation or a screen sharing operation, the first electronic device sends a third image to the second electronic device, so that the second electronic device, after receiving the third image, can display it. Therefore, in screen mirroring or screen sharing scenarios, the third image displayed by the second electronic device is different from the first image displayed by the first electronic device, thereby ensuring that the third image displayed by the second electronic device does not involve copyright or privacy information and does not include pop-up prompts, thus better protecting the user's privacy or copyright.

[0018] A second aspect of this application provides a secure display method, comprising: a first electronic device displaying a first image; the first electronic device receiving a first operation from a user, the first operation being used to acquire the first image displayed by the first electronic device; in response to the user's first operation, if the first electronic device determines that a first control in the first image includes a security identifier, the first electronic device covers the first control with a second preset layer to generate a fourth image. Based on this solution, when the first electronic device determines that a control in the first image includes a security identifier, by covering the control including the security identifier with a second preset layer, the generated fourth image does not display the control including the security identifier, thus providing more precise protection of user privacy and improving user experience. Moreover, this solution does not require user editing to generate a fourth image that does not display user privacy or copyright information, thereby improving user experience. This solution can process security controls so that the information of the controls cannot be seen by other users, thus not only protecting user security but also further improving the user experience due to the smaller area of ​​security processing.

[0019] In conjunction with the second aspect, in one possible implementation, the first electronic device uses a second preset layer to cover the first control to generate a fourth image. This includes: the first electronic device acquiring the position information of the first control within the first image; and based on this position information, the first electronic device using the second preset layer to cover the area where the first control is located to generate the fourth image. Based on this solution, by using a second preset layer to cover the first control, including the security identifier, the generated fourth image does not display the first control, meaning the first control is invisible to the user. This ensures that the generated fourth image does not display the information of the first control, protecting user privacy without requiring manual editing and improving the user experience. Furthermore, because the area of ​​security processing is smaller, the user experience is further enhanced.

[0020] Combining the second aspect and the aforementioned possible implementations, in another possible implementation, the second preset layer includes a prompt message to inform the user that the first control includes security information. Based on this solution, the prompt message in the second preset layer allows the user to understand why the fourth image differs from the first image, thus improving the user experience.

[0021] Optionally, the prompt information in the second preset layer can be text information such as "Security control prohibits screenshot" or "Security control prohibits screen recording", or it can be an animated or icon prompt. This application does not limit the specific content and type of the prompt information.

[0022] In conjunction with the second aspect and the aforementioned possible implementations, in another possible implementation, the first operation includes a screenshot operation, a screen recording operation, a screen casting operation, or a screen sharing operation. Based on this solution, when the first electronic device receives a user's screenshot operation, screen recording operation, screen casting operation, or screen sharing operation, in response to the operation, the first electronic device further determines whether the first control in the first image includes a security identifier. If the first electronic device determines that the first control in the first image includes a security identifier, the first electronic device uses a second preset layer to cover the first control and generates a fourth image, thereby ensuring that the layer including the security identifier is not displayed in the generated fourth image, thus protecting the user's privacy.

[0023] In conjunction with the second aspect and the aforementioned possible implementations, in another possible implementation, when the first operation is a screenshot or screen recording operation, the method further includes: the first electronic device displaying the fourth image. Based on this solution, when the user input operation is a screenshot or screen recording operation, the first electronic device overwrites the first control in the fourth image to generate the fourth image, and displays the processed fourth image on the display screen. It is understood that the fourth image displayed by the first electronic device does not show control information, thus protecting user privacy.

[0024] In conjunction with the second aspect and the aforementioned possible implementations, in another possible implementation, when the first operation is a screen projection or screen sharing operation, the method further includes: the first electronic device sending the fourth image to the second electronic device. Based on this solution, when the user input operation is a screen projection or screen sharing operation, the first electronic device overlays the first control in the first image to generate a fourth image and sends the fourth image to the second electronic device. Upon receiving the fourth image, the second electronic device can display it. Therefore, in screen projection or screen sharing scenarios, the fourth image displayed by the second electronic device is different from the first image displayed by the first electronic device, thus ensuring that security information is not leaked.

[0025] In conjunction with the second aspect and the aforementioned possible implementations, in another possible implementation, the method further includes: the first electronic device receiving a second operation from a user, the second operation being used to activate a security switch control; in response to the user's second operation, the electronic device filtering the third layer in the fourth image to generate a fifth image; the third layer including pop-up notification information. Based on this solution, by activating the security switch control, the pop-up notification information of the first electronic device can be further filtered, therefore the generated fifth image does not include pop-up notification information, thus preventing other users from seeing user SMS notifications or application notifications, and better protecting user privacy information.

[0026] In conjunction with the second aspect and the aforementioned possible implementations, in another possible implementation, when the first operation is a screenshot or screen recording operation, the method further includes: the first electronic device displaying the fifth image. Based on this solution, when the user input operation is a screenshot or screen recording operation, the first electronic device displays the processed fifth image on the display screen. It is understood that the fifth image displayed by the first electronic device does not involve copyright or privacy information and does not include pop-up prompts, thus better protecting the user's privacy or copyright.

[0027] In conjunction with the second aspect and the aforementioned possible implementations, in another possible implementation, when the first operation is a screen casting or screen sharing operation, the method further includes: the first electronic device sending the fifth image to the second electronic device. Based on this solution, when the user input is a screen casting or screen sharing operation, the first electronic device sends the fifth image to the second electronic device, so that the second electronic device, after receiving the fifth image, can display it. Therefore, in screen casting or screen sharing scenarios, the fifth image displayed by the second electronic device is different from the first image displayed by the first electronic device, thereby ensuring that the fifth image displayed by the second electronic device does not involve copyright or privacy information and does not include pop-up prompts, thus better protecting the user's privacy or copyright.

[0028] A third aspect of this application provides a secure display method, comprising: a first electronic device displaying a first image; the first electronic device receiving a first operation from a user, the first operation being used to acquire the first image displayed by the first electronic device; if the first electronic device determines that a security switch control is not turned on, in response to the first operation, if the first electronic device determines that a first layer in the first image includes a security identifier, the first electronic device replaces or covers the first layer with a first preset layer to generate a second image; if the first electronic device determines that the security switch control is turned on, in response to the first operation, if the first electronic device determines that a first layer in the first image includes a security identifier, the first electronic device replaces or covers the first layer with a first preset layer and filters a third layer to generate a third image; the third layer includes a pop-up prompt message. Based on this solution, after receiving the user's first operation, the first electronic device further determines whether the security switch control is turned on. If it determines that the security switch control is not turned on, and if the first electronic device determines that a layer in the first image includes a security identifier, by replacing or covering the layer including the security identifier with a first preset layer, the layer including the security identifier is not displayed in the generated second image, thus protecting the user's privacy or copyright. Furthermore, this solution generates a second image that does not display user privacy or copyright information without requiring user editing, thus improving the user experience. When the security switch control is confirmed to be enabled, if the first electronic device determines that a layer in the first image includes a security identifier, it replaces or overwrites the layer containing the security identifier with a first preset layer and filters the third layer. This ensures that the generated third image neither displays the layer containing the security identifier nor any pop-up notifications, thereby further protecting user privacy and enhancing the user experience.

[0029] In conjunction with the third aspect, in one possible implementation, the aforementioned first operation includes a screenshot operation, a screen recording operation, a screen casting operation, or a screen sharing operation. Based on this solution, when the first electronic device receives a user's screenshot operation, screen recording operation, screen casting operation, or screen sharing operation, the first electronic device further determines whether the security switch control is enabled. If the security switch control is determined to be disabled, and if the first electronic device determines that a layer in the first image includes a security identifier, the first electronic device replaces or overwrites the first layer with a first preset layer and generates a second image, thereby ensuring that the generated second image does not display the layer containing the security identifier, thus protecting the user's privacy or copyright. If the security switch control is determined to be enabled, and if the first electronic device determines that a layer in the first image includes a security identifier, by replacing or overwriting the layer containing the security identifier with a first preset layer and filtering the third layer, the generated third image neither displays the layer containing the security identifier nor any pop-up notification information, thus further protecting the user's privacy and improving the user experience.

[0030] A fourth aspect of this application provides a secure display method, comprising: a first electronic device displaying a first image; the first electronic device receiving a first operation from a user, the first operation being used to acquire the first image displayed by the first electronic device; if the first electronic device determines that a security switch control is not turned on, in response to the first operation, if the first electronic device determines that a first control in the first image includes a security icon, the first electronic device covers the first control with a second preset layer to generate a fourth image; if the first electronic device determines that the security switch control is turned on, in response to the first operation, if the first electronic device determines that a first control in the first image includes a security icon, the first electronic device replaces or covers the first layer with a second preset layer and filters a third layer to generate a fifth image; the third layer includes pop-up prompt information. Based on this solution, after receiving the user's first operation, the first electronic device further determines whether the security switch control is turned on. If it determines that the security switch control is not turned on, and if the first electronic device determines that a control in the first image includes a security icon, by covering the control including the security icon with a second preset layer, the control including the security icon is not displayed in the generated fourth image, thus protecting the user's privacy. Furthermore, this solution generates a fourth image that does not display user privacy or copyright information without requiring user editing, thus improving the user experience. If the first electronic device determines that the control in the first image includes a security symbol when the security switch control is enabled, it covers the control containing the security symbol with a second preset layer and filters the third layer. This ensures that the generated fifth image neither displays the control containing the security symbol nor any pop-up notifications, further protecting user privacy and enhancing the user experience.

[0031] In conjunction with the fourth aspect, in one possible implementation, the aforementioned first operation includes a screenshot operation, a screen recording operation, a screen casting operation, or a screen sharing operation. Based on this solution, when the first electronic device receives a user's screenshot operation, screen recording operation, screen casting operation, or screen sharing operation, the first electronic device further determines whether the security switch control is enabled. If the security switch control is not enabled, and the first electronic device determines that the control in the first image includes a security symbol, it covers the control including the security symbol with a second preset layer, thereby preventing the control including the security symbol from being displayed in the generated fourth image, thus protecting the user's privacy. Moreover, this solution does not require user editing to generate a fourth image that does not display user privacy or copyright information, thus improving the user experience. If the security switch control is enabled, and the first electronic device determines that the control in the first image includes a security symbol, it covers the control including the security symbol with a second preset layer and filters the third layer, thereby preventing the control including the security symbol from being displayed in the generated fifth image, and also preventing the display of pop-up prompts, thus further protecting the user's privacy information and improving the user experience.

[0061] The technical solutions in the embodiments of this application will be described below with reference to the accompanying drawings. In this application, "at least one" means one or more, and "more than one" means two or more. "And / or" describes the relationship between related objects, indicating that there can be three relationships. For example, A and / or B can mean: A exists alone, A and B exist simultaneously, or B exists alone, where A and B can be singular or plural. The character " / " generally indicates that the related objects before and after are in an "or" relationship. "At least one of the following" or similar expressions refer to any combination of these items, including any combination of single or plural items. For example, at least one of a, b, or c can mean: a, b, c, a and b, a and c, b and c, or a and b and c, where a, b, and c can be single or multiple. Furthermore, to facilitate a clear description of the technical solutions in the embodiments of this application, the terms "first" and "second" are used in the embodiments of this application to distinguish identical or similar items with essentially the same function and effect. Those skilled in the art will understand that the terms "first" and "second" do not limit the quantity or execution order. For example, the "first" in the first preset layer and the "second" in the second preset layer in the embodiments of this application are only used to distinguish different preset layers. The descriptions of "first" and "second" appearing in the embodiments of this application are only for illustration and to distinguish the described objects, and have no order, nor do they indicate a special limitation on the number of devices in the embodiments of this application, and cannot constitute any limitation on the embodiments of this application.

[0062] It should be noted that, in this application, the terms "exemplary" or "for example" are used to indicate that something is being described as an example, illustration, or illustration. Any embodiment or design described as "exemplary" or "for example" in this application should not be construed as being more preferred or advantageous than other embodiments or design solutions. Specifically, the use of terms such as "exemplary" or "for example" is intended to present the relevant concepts in a concrete manner.

[0063] First, a brief introduction to the terms used in this application.

[0064] A screenshot (also known as a screen capture or screenshot image) is an image captured by an electronic device and displayed on its screen or other display device. There are usually several ways to take a screenshot. For example, a user can simultaneously press and hold the volume down button ("-") and the lock screen button to take a screenshot of the phone's display. Another example is using the system's screenshot control. Yet another example is using screenshot software to take a screenshot of a computer's display.

[0065] Screen recording, or recording the screen, is the recording of the interface displayed on an electronic device. It is usually done using screen recording software. For example, screen recording software can be used to record the operation of a specific application on an electronic device.

[0066] Screen mirroring is the process of projecting an application running on a first electronic device onto a second electronic device, allowing the application to be displayed and run on the second device. When using screen mirroring, a communication connection is established between the first and second electronic devices. This connection can be wired (e.g., a data cable connection) or wireless (e.g., Bluetooth or Wi-Fi). For example, if a mobile phone and a laptop are connected to the same Wi-Fi network, and the mobile phone is running the Tencent Video app, in a screen mirroring scenario, the mobile phone can send a message to the laptop via Wi-Fi, allowing the video to be played on the laptop. Typically, the content mirrored is streaming audio or video resources.

[0067] Optionally, in screen mirroring scenarios, since the application interface is being projected, the interface displayed on the second electronic device may differ from that displayed on the first electronic device. For example, after casting a video playing on a mobile phone to a TV, the user can browse photo albums or other applications, while the TV continues to play the cast video. Therefore, the interface displayed on the mobile phone is inconsistent with the interface displayed on the laptop.

[0068] Screen sharing is the process of synchronously displaying the interface of a first electronic device on a second electronic device. When using screen sharing, a communication connection is established between the first and second electronic devices. For example, the first and second electronic devices may be connected to the same Wi-Fi network. Generally, there are no restrictions on the content that can be shared; web pages, games, office documents, videos, and other content can be shared to other devices. Optionally, in a screen sharing scenario, only the interface displayed on the first electronic device is shared. Therefore, when a user triggers an operation on the first electronic device, the interface responding to that operation will be synchronously displayed on the second electronic device; that is, the interface displayed on the second electronic device is identical to the interface displayed on the first electronic device.

[0069] Electronic devices often incorporate numerous design features and capabilities to facilitate user communication, such as screenshots, screen recording, screen sharing, and screen casting. When using electronic devices, users can share the device's or application's display interface with other users through these methods. However, sharing the interface may include sensitive information such as friends' or contacts' avatars, names, and user account passwords. Directly sharing this information could lead to privacy breaches, potentially exposing the user's own or others' privacy, posing ethical or legal risks. Typically, to avoid leaking their own or others' privacy, users can use editing tools to blur or pixelate sensitive information before sending. However, this method is cumbersome and provides a poor user experience.

[0070] To address the aforementioned issues, one display method involves third-party applications configuring a security flag (LayoutParams.FLAG_SECURE) on the interface. When the operating system performs image display composition, if it recognizes this security flag, it will filter out this interface.

[0071] like Figure 1 As shown in (a), the mobile phone runs a first application whose display interface includes a "person" that involves copyright. The first application pre-configures a security identifier on this display interface. In a screenshot scenario, the mobile phone receives the user's screenshot operation and, in response, after recognizing that the first application's display interface includes the security identifier, filters the first application's display interface, as follows: Figure 1 As shown in (b), in a screenshot scenario, the screenshot image has no content. In a screen mirroring or screen sharing scenario, the phone receives the user's screen mirroring or screen sharing operation and, in response to the operation, after recognizing that the display interface of the first application includes a security icon, the phone filters the display interface of the first application and sends the filtered image to the laptop, such as... Figure 1 As shown in (c), the laptop screen is empty during screen mirroring or screen sharing.

[0072] The above display method will cause users to not understand how the layers are isolated, which may lead to product complaints.

[0073] Another method involves the electronic device blocking screenshots and screen recordings upon recognizing the aforementioned security identifier. For example, after recognizing the security identifier, the electronic device displays a prompt message and simultaneously stops screenshotting or screen recording.

[0074] like Figure 2As shown in (a), the phone runs a first application whose display interface is "People." These "People" involve copyright issues, and the first application has a security flag pre-configured on this display interface. In a screen recording scenario, when the control policy is in effect, calls to the screen recording function from the user interface or background programs will be blocked by the system, such as... Figure 2 As shown in (b), in the screen recording scenario, the phone blocks the screen recording operation and displays the message "Security policy prohibits screen recording" on the display interface of the first application.

[0075] While users understand the rationale behind this solution, its granular control is too strict. During the policy's effective period, screen recording or screenshotting is prohibited on any interface. However, the secure interface may only be part of the user's screen recording process. Completely blocking screen recording will result in a poor user experience. Furthermore, this method makes it impossible for users to accurately know which interfaces can be recorded and which cannot.

[0076] In order to improve user experience while protecting user privacy or copyright, this application provides a secure display method. This method can prompt users that the current page involves security issues while protecting user privacy information or copyright, thereby improving user experience.

[0077] In this embodiment, both the first electronic device and the second electronic device include a display screen. The first electronic device and the second electronic device may include, but are not limited to, mobile phones, tablets, desktop computers, laptops, handheld computers, notebook computers, personal computers (PCs), ultra-mobile personal computers (UMPCs), netbooks, as well as cellular phones, smartwatches, smart bracelets, phone watches, smart cameras, personal digital assistants (PDAs), augmented reality (AR) / virtual reality (VR) devices, televisions, projection devices, or motion-sensing game consoles in human-computer interaction scenarios, etc., all of which include a display screen.

[0097] The modem processor may include a modulator and a demodulator. The modulator modulates the low-frequency baseband signal to be transmitted into a mid-to-high frequency signal. The demodulator demodulates the received electromagnetic wave signal into a low-frequency baseband signal. The demodulator then transmits the demodulated low-frequency baseband signal to the baseband processor for processing. After processing by the baseband processor, the low-frequency baseband signal is transmitted to the application processor. The application processor outputs sound signals through audio devices (not limited to speaker 170A, receiver 170B, etc.) or displays images or videos through the display screen 194. In some embodiments, the modem processor may be a separate device.

[0103] Electronic device 100 can perform shooting functions through ISP, camera 193, video codec, GPU, display 194 and application processor.

[0104] The ISP (Image Signal Processor) is used to process data fed back from the camera 193. For example, when taking a picture, the shutter is opened, and light is transmitted through the lens to the camera's photosensitive element. The light signal is converted into an electrical signal, and the camera's photosensitive element transmits the electrical signal to the ISP for processing, transforming it into an image visible to the naked eye. The ISP can also perform algorithmic optimization of image noise, brightness, and skin tone. The ISP can also optimize parameters such as exposure and color temperature of the shooting scene. In some embodiments, the ISP can be set in the camera 193.

[0105] Camera 193 is used to capture still images or videos. An object is projected onto a photosensitive element by generating an optical image through the lens. The photosensitive element can be a charge-coupled device (CCD) or a complementary metal-oxide-semiconductor (CMOS) phototransistor. The photosensitive element converts the light signal into an electrical signal, which is then passed to an ISP for conversion into a digital image signal. The ISP outputs the digital image signal to a DSP for processing. The DSP converts the digital image signal into image signals in standard RGB, YUV, or other formats. In some embodiments, the electronic device 100 may include one or N cameras 193, where N is a positive integer greater than 1.

[0106] Digital signal processors (DSPs) are used to process digital signals. Besides digital image signals, they can also process other digital signals. For example, when electronic device 100 selects a frequency, the DSP can perform Fourier transforms on the frequency energy.

[0107] Video codecs are used to compress or decompress digital video. Electronic device 100 may support one or more video codecs. Thus, electronic device 100 can play or record videos in various encoding formats, such as Moving Picture Experts Group (MPEG) 1, MPEG2, MPEG3, MPEG4, etc.

[0108] An NPU (Neural Processing Unit) is a computational processor for neural networks (NNs). By borrowing the structure of biological neural networks, such as the transmission patterns between neurons in the human brain, it can rapidly process input information and continuously learn on its own. NPUs enable intelligent cognitive applications in electronic devices, such as image recognition, facial recognition, speech recognition, and text understanding.

[0109] The external storage interface 120 can be used to connect an external memory card, such as a Micro SD card, to expand the storage capacity of the electronic device 100. The external memory card communicates with the processor 110 through the external storage interface 120 to perform data storage functions. For example, music, video, and other files can be saved on the external memory card.

[0110] Internal memory 121 can be used to store computer executable program code, which includes instructions.

Audio module 170 can also be used for encoding and decoding audio signals. In some embodiments, audio module 170 may be located in processor 110, or some functional modules of audio module 170 may be located in processor 110. Speaker 170A, also called a "loudspeaker," is used to convert audio electrical signals into sound signals. Electronic device 100 can listen to music or hands-free calls through speaker 170A. Receiver 170B, also called a "handpiece," is used to convert audio electrical signals into sound signals. When electronic device 100 answers a phone call or voice message, it can listen to the voice by bringing receiver 170B close to the user's ear. Microphone 170C, also called a "microphone" or "voice transducer," is used to convert sound signals into electrical signals. When making a phone call or sending a voice message, the user can speak by bringing their mouth close to microphone 170C, inputting sound signals into microphone 170C.

[0113] The 170D headphone jack is used to connect wired headphones. The 170D headphone jack can be a USB 130 interface or a 3.5mm Open Mobile Terminal Platform (OMTP) standard interface, a CTIA (Cellular Telecommunications Industry Association of the USA) standard interface.

[0114] Pressure sensor 180A is used to sense pressure signals and convert them into electrical signals. In some embodiments, pressure sensor 180A can be disposed on display screen 194. There are many types of pressure sensors 180A, such as resistive pressure sensors, inductive pressure sensors, and capacitive pressure sensors. A capacitive pressure sensor may include at least two parallel plates with conductive material. When force is applied to pressure sensor 180A, the capacitance between the electrodes changes. Electronic device 100 determines the pressure intensity based on the change in capacitance. When a touch operation is applied to display screen 194, electronic device 100 detects the intensity of the touch operation based on pressure sensor 180A. Electronic device 100 can also calculate the touch position based on the detection signal from pressure sensor 180A. In some embodiments, touch operations applied to the same touch position but with different touch operation intensities can correspond to different operation commands. For example, when a touch operation with an intensity less than a first pressure threshold is applied to the SMS application icon, a command to view an SMS is executed. When a touch operation with an intensity greater than or equal to the first pressure threshold is applied to the SMS application icon, a command to create a new SMS is executed.

[0115] The gyroscope sensor 180B can be used to determine the motion attitude of the electronic device 100. In some embodiments, the gyroscope sensor 180B can determine the angular velocity of the electronic device 100 about three axes (i.e., the x, y, and z axes). The gyroscope sensor 180B can be used for image stabilization. For example, when the shutter is pressed, the gyroscope sensor 180B detects the angle of the shake of the electronic device 100, calculates the distance that the lens module needs to compensate based on the angle, and allows the lens to counteract the shake of the electronic device 100 by moving in the opposite direction, thus achieving image stabilization. The gyroscope sensor 180B can also be used in navigation and motion-sensing game scenarios.

[0116] The barometric pressure sensor 180C is used to measure air pressure. In some embodiments, the electronic device 100 calculates altitude using the air pressure value measured by the barometric pressure sensor 180C to assist in positioning and navigation.

[0119] A distance sensor 180F is used to measure distance. Electronic device 100 can measure distance via infrared or laser. In some embodiments, during a shooting scene, electronic device 100 can utilize the distance sensor 180F to measure distance for rapid focusing.

[0120] The proximity sensor 180G may include, for example, a light-emitting diode (LED) and a light detector, such as a photodiode. The LED may be an infrared LED. The electronic device 100 emits infrared light outward through the LED. The electronic device 100 uses the photodiode to detect infrared reflected light from nearby objects. When sufficient reflected light is detected, it can be determined that there is an object near the electronic device 100. When insufficient reflected light is detected, the electronic device 100 can determine that there is no object near the electronic device 100. The electronic device 100 may use the proximity sensor 180G to detect when a user holds the electronic device 100 close to their ear for a call, so as to automatically turn off the screen to save power. The proximity sensor 180G can also be used in holster mode and pocket mode for automatic unlocking and locking of the screen.

[0121] The ambient light sensor 180L is used to sense the brightness of ambient light. The electronic device 100 can adaptively adjust the brightness of the display screen 194 based on the sensed ambient light brightness. The ambient light sensor 180L can also be used to automatically adjust the white balance when taking pictures. The ambient light sensor 180L can also work with the proximity sensor 180G to detect whether the electronic device 100 is in a pocket to prevent accidental touches.

[0123] Temperature sensor 180J is used to detect temperature. In some embodiments, electronic device 100 uses the temperature detected by temperature sensor 180J to execute a temperature handling strategy. For example, when the temperature reported by temperature sensor 180J exceeds a threshold, electronic device 100 performs thermal protection by reducing the performance of a processor located near temperature sensor 180J to reduce power consumption. In other embodiments, when the temperature is below another threshold, electronic device 100 heats battery 142 to prevent abnormal shutdown of electronic device 100 due to low temperature. In still other embodiments, when the temperature is below yet another threshold, electronic device 100 boosts the output voltage of battery 142 to prevent abnormal shutdown due to low temperature.

[0124] Touch sensor 180K, also known as a "touch panel," can be located on display screen 194. The touch sensor 180K and display screen 194 together form a touchscreen, also known as a "touch screen." Touch sensor 180K detects touch operations applied to or near it. The touch sensor can transmit the detected touch operation to the application processor to determine the type of touch event. Visual output related to the touch operation can be provided through display screen 194. In other embodiments, touch sensor 180K may also be located on the surface of electronic device 100, in a different position than display screen 194.

In some embodiments, the bone conduction sensor 180M can also be incorporated into headphones to form bone conduction headphones. The audio module 170 can parse the voice signals from the vibrating bone segments of the vocal cords acquired by the bone conduction sensor 180M to realize voice functionality. The application processor can parse heart rate information from the blood pressure signals acquired by the bone conduction sensor 180M to realize heart rate detection functionality.

For example, different vibration feedback effects can correspond to touch operations performed on different applications (such as taking photos, playing audio, etc.). Motor 191 can also correspond to different vibration feedback effects for touch operations performed on different areas of the display screen 194. Different application scenarios (such as time reminders, receiving messages, alarm clocks, games, etc.) can also correspond to different vibration feedback effects. The touch vibration feedback effect can also be customized.

Optionally, when the screen of the first electronic device displays the interface of the first application in full screen, the display interface of the first electronic device is the same as the display interface of the first application.

[0145] Optionally, the first image may include multiple layers, and the first image is a composite of the multiple layers.

[0146] S402, The first electronic device receives the user's first operation.

[0147] The first operation is used to acquire the first image.

[0148] Optionally, the first operation may include a screenshot operation, a screen recording operation, a screen sharing operation, or a screen projection operation. It should be noted that, in this embodiment, the first operation may also be other operations for acquiring a first image displayed on an electronic device; this embodiment does not limit the specific form of the first operation.

[0149] For example, when the first operation is a screenshot operation, the screenshot operation is used to capture the interface displayed by the first electronic device. For instance, such as... Figure 5As shown in (a), when a user simultaneously presses the lock screen button and the volume down button ("-") to trigger a screenshot operation, the electronic device receives the user's screenshot operation. Optionally, the screenshot operation triggered by the user can also be triggered through the screenshot control in the drop-down menu, or through a specific gesture. This application embodiment does not limit the specific triggering method of the screenshot operation, and it is only an exemplary description here.

[0150] For example, when the first operation is a screen recording operation, this screen recording operation can be used to acquire multiple frames of the first image, which are the interface displayed by the first electronic device at different times. For example, such as Figure 5 As shown in (b) above, when the user clicks the "Screen Recording" control, the electronic device receives the user's click. Optionally, the user can also trigger the screen recording operation through screen recording software. This application embodiment does not limit the specific triggering method of the screen recording operation; it is only an illustrative example.

[0151] For example, when the first operation is a screen sharing operation, the screen sharing operation is used to acquire the interface displayed by the first electronic device. For instance, such as... Figure 5 As shown in (c), when the user clicks the "Wireless Screen Sharing" control, the electronic device receives the user's screen sharing operation. This application embodiment does not limit the specific triggering method for the screen sharing operation; it is merely an illustrative example.

[0152] For example, when the first operation is a screen mirroring operation, the user can trigger the screen mirroring operation by clicking the screen mirroring control in the first application running on the first electronic device. For example, as Figure 5 As shown in (d), the first electronic device runs a first application to watch a video. After the user clicks the screen casting control in the first application, they can select a screen casting device, and the electronic device receives the user's screen casting operation. This application embodiment does not limit the specific triggering method of the screen casting operation; it is merely an illustrative example.

[0153] It should be noted that this application does not strictly distinguish between screen casting and screen sharing scenarios. Any scenario in which the interface displayed on the first electronic device is projected onto the second electronic device can be called a screen casting scenario or a screen sharing scenario. Any user-triggered operation to project the interface displayed on the first electronic device onto the second electronic device can be called a screen sharing operation or a screen casting operation. For example, such as... Figure 5 As shown in (c), the user's action of clicking the "Wireless Screen Casting" control can also be called a screen casting operation. For example, as... Figure 5 As shown in (d) in the diagram, after clicking the screen casting control in the first application, the user can select a screen casting device. This series of operations can also be called screen sharing operations.

[0154] Optionally, the first operation described above, which acquires the first image, can be achieved through one trigger action or through multiple trigger actions.

[0155] S403. In response to the user's first operation, if the first electronic device determines that the first layer in the first image includes a security symbol, the first electronic device replaces or covers the first layer with a first preset layer and generates a second image.

[0156] For example, in response to a user's screenshot, screen recording, screen sharing, or screen casting operation, the first electronic device determines whether the multiple layers included in the first image include a security identifier.

[0157] Optionally, the security identifier can be a pre-configured identifier for the application or system. For example, the application or system can pre-configure security identifiers for layers related to security, such as copyright and user privacy. Optionally, the security identifier can be LayoutParams.FLAG_SECURE.

[0158] In one implementation, if the first electronic device determines that the first layer in the first image includes a security identifier, the first layer can be replaced with a first preset layer, and a second image can be generated.

[0159] For example, the first electronic device can replace the first layer with a first preset layer and composite the second layer (excluding the security symbol) from the first image with the first preset layer to generate a second image. In other words, when generating the second image, the first electronic device replaces the first layer in the first image with the first preset layer, and then composites the second layer (excluding the security symbol) from the first image with the first preset layer to obtain the second image. Therefore, the generated second image no longer includes the first layer, thus protecting copyright if the first layer involves copyright issues, and protecting user privacy if the first layer includes user privacy information.

[0160] In this implementation, by replacing the first layer with a first preset layer, the generated second image no longer includes the first layer, thus ensuring that the generated second image does not contain user privacy or copyright information. This solution protects copyright or user privacy information without requiring manual editing by the user, improving the user experience.

[0161] In another implementation, if the first electronic device determines that the first layer in the first image includes a security identifier, it can use a first preset layer to cover the first layer and generate a second image.

[0162] For example, when the first electronic device uses a first preset layer to cover the first layer, it can composite multiple layers of the first image with the first preset layer. Moreover, during the composite, the first preset layer is located above the first layer, so that the first layer can be covered by the first preset layer.

[0163] In this implementation, although the second image still includes the first layer, it is covered by a first preset layer. Therefore, the generated second image does not display the first layer, making it invisible to the user. This ensures that the generated second image does not display user privacy or copyright information. This solution protects copyright or user privacy without requiring manual editing by the user, thus improving the user experience.

[0164] Optionally, the aforementioned first preset layer may include a prompt message to inform the user that the first image includes security information. This security information is security-related and may involve user privacy or copyright, etc. This prompt message helps the user understand why the second image differs from the first image, improving the user experience.

[0165] For example, the prompt information in the first preset layer can be text information such as "Safe interface prohibits screenshots" or "Safe interface prohibits screen recording", or it can be an animated or icon prompt information. This application does not limit the specific content and type of the prompt information.

[0166] Optionally, the size of the first preset layer can be the same as the size of the first layer.

[0167] Understandably, the display method provided in this application, when acquiring an image displayed by a first electronic device, identifies whether the first image includes a security identifier. If it is determined that the first layer in the first image includes a security identifier, a first preset layer is used to replace or cover the first layer, and a second image is generated. Therefore, the first layer is not displayed in the generated second image, thereby ensuring that the generated second image protects the user's privacy information and copyright. This solution protects copyright or user privacy information without requiring manual editing by the user, and by prompting the user that the current page involves security, the user can understand the action, thus improving the user experience.

[0168] Optional, such as Figure 6 As shown, when the first operation is a screenshot operation or a screen recording operation, the above display method may include step S404 in addition to the steps S401-S403 described above.

[0169] S404, The first electronic device displays the second image.

[0170] For example, a first electronic device replaces or overwrites a first layer in a first image to generate a second image, and displays the processed second image on a display screen. It is understood that the second image displayed by the first electronic device does not involve copyright or privacy information.

[0171] For example, in a screenshot scenario, the first image displayed on the phone is like... Figure 7 As shown in (a) in the example, Figure 7 The first image shown in (a) is composed of multiple layers. The layer containing the "person" involves copyright, and a third-party application pre-configures a security identifier for this layer. When a user triggers a screenshot operation, the phone receives the screenshot operation. In response to this operation, the phone recognizes that the layer containing the "person" in the first image includes a security identifier. It can then replace the first layer with a first preset layer, and then combine the second layer in the first image (which does not include a security identifier) ​​with the first preset layer to generate the image shown in (a). Figure 7 The second image shown in (b) does not display "people". The phone can display this second image after it is generated.

[0172] For example, in a screenshot scenario, the first image displayed on the phone is like... Figure 7 As shown in (c) in the example, Figure 7 The first image shown in (c) is composed of multiple layers. The account password involves user privacy information, and the third-party application pre-configures a security identifier for the layer containing the account password. When the user triggers a screenshot operation, the phone receives the screenshot operation. In response to the screenshot operation, after recognizing that the layer containing the user's account password in the first image includes the security identifier, the phone can overlay the first layer with a first preset layer to generate an image as shown in (c). Figure 7 The second image is shown in (d) above. Understandably, after overlaying the first layer with the first preset layer, the generated second image does not display the user account password information. The phone can display this second image after it is generated.

[0173] It should be noted that, in the screenshot scenario, when the first image displayed by the first electronic device involves security information such as copyright or privacy, the display method of this application embodiment will not prevent the user from taking a screenshot. Instead, the security information involving copyright or privacy will not be displayed in the screenshot image (second image), and the user will be prompted that the current interface is a safe interface, thereby enabling the user to understand the behavior and improving the user experience.

[0174] For example, in screen recording scenarios, using the phone's display interface as... Figure 8Taking (a) as an example, when a user triggers a screen recording operation, the phone receives the user's screen recording operation. In response to this operation, if the phone recognizes that the layer containing the "person" in the first image includes a security icon, then the phone can replace the first layer with a first preset layer, and then combine the second layer (which does not include the security icon) in the first image with the first preset layer to generate a second image. Figure 8 As shown in (b), the first electronic device displays the second image when recording the screen, and the second image does not display "people".

[0175] For example, in screen recording scenarios, using the phone's display interface as... Figure 8 Taking (c) as an example, when a user triggers a screen recording operation, the mobile phone receives the user's screen recording operation. In response to this operation, if the mobile phone recognizes that the layer containing the user's account password in the first image includes a security icon, it can use a first preset layer to overlay the first layer, thus obtaining a second image. Figure 8 As shown in (d) above, the phone displays a second image during screen recording. Understandably, after overlaying the first layer with the first preset layer, the generated second image does not display the user account password information.

[0176] It should be noted that, in the screen recording scenario, when the first image displayed by the first electronic device involves security information such as copyright or privacy, the recording process will not be interrupted. The security information involving copyright or privacy will not be displayed on the first electronic device, and the user will be prompted that the current interface is a safe interface, thereby enabling the user to understand the behavior and improving the user experience.

[0177] The display method provided in this application embodiment, in response to a user-triggered screenshot or screen recording operation, involves a first electronic device acquiring a first image and identifying whether the first image includes a security identifier. If it is determined that the first layer in the first image includes a security identifier, a second image is generated by replacing or overwriting the first layer with a first preset layer, and the first electronic device displays the second image. Therefore, the first layer is not displayed in the generated second image, thereby ensuring that the generated second image does not leak user privacy information or infringe copyright. This solution protects copyright or user privacy information without requiring manual editing by the user, and by prompting the user that the current interface is a secure interface, it helps the user understand the action, thus improving the user experience.

[0178] Optional, such as Figure 9 As shown, when the first operation is a screen projection operation or a screen sharing operation, the above display method may include steps S405-S407 in addition to the steps S401-S403 described above.

[0179] S405, The first electronic device sends a second image to the second electronic device.

[0180] The second electronic device can be the same type of device as the first electronic device, or it can be a different type of device than the first electronic device.

[0181] For example, in response to a user's screen mirroring or screen sharing operation, the first electronic device replaces or overwrites the first layer in the first image to generate a second image, and then sends the second image to the second electronic device. It is understood that the second image sent by the first electronic device to the second electronic device does not involve copyright or privacy information.

[0182] S406, The second electronic device receives the second image.

[0183] S407, The second electronic device displays the second image.

[0184] For example, since the second image is generated after the first image has been replaced or overwritten, the content displayed by the second image is different from that of the first image. Therefore, the second image displayed by the second electronic device is different from the first image displayed by the first electronic device.

[0185] For example, in screen mirroring or screen sharing scenarios, the phone's display interface, such as... Figure 10 Taking (a) as an example, when a user triggers a screen mirroring or screen sharing operation, the mobile phone receives the screen mirroring or screen sharing operation and, in response to the operation, acquires the first image it displays. Since the "person" involves copyright, after the mobile phone recognizes that the layer containing the "person" in the first image includes a security identifier, it can replace the first layer with a first preset layer, and then combine the second layer (which does not include the security identifier) ​​in the first image with the first preset layer to obtain the second image. The mobile phone sends the second image to the laptop computer, and the laptop computer receives the second image and displays it on its screen, as shown below. Figure 10 As shown in (b), the second image displayed by the laptop does not include "people".

[0186] For example, in screen mirroring or screen sharing scenarios, the phone's display interface, such as... Figure 10 Taking (c) as an example, when a user triggers a screen mirroring or screen sharing operation, the mobile phone receives the screen mirroring or screen sharing operation and, in response to the operation, acquires a first image. Since this first image includes the user's account password information, which involves user privacy, the mobile phone, after recognizing that the layer containing the user's account password in the first image includes a security identifier, can overlay the first layer with a first preset layer to obtain a second image. The mobile phone sends the second image to the laptop computer, and the laptop computer receives the second image and displays it on its screen, as shown below. Figure 10 As shown in (d) above, the second image displayed by the laptop does not include the user's private information. (Combined with...) Figure 10 (c) and Figure 10 As shown in (d), when the user enters their account and password, the user's account and password information is not displayed on the mobile phone screen projected from the laptop.

[0187] It is understood that, in this embodiment of the application, the first layer involving security information in the first image is replaced or covered, so that the first layer is not displayed in the generated second image. Therefore, in the scenario of screen projection or screen sharing, the second image displayed by the second electronic device is different from the first image displayed by the first electronic device, thereby ensuring that security information is not leaked.

[0188] The display method provided in this application embodiment, in response to a user-triggered screen projection or screen sharing operation, involves a first electronic device acquiring a first image and identifying whether the first image includes a security identifier. If it is determined that the first layer in the first image includes a security identifier, a second image is generated by replacing or overwriting the first layer with a first preset layer. The first electronic device sends the second image to a second electronic device, which receives and displays the second image. Therefore, the second image displayed by the second electronic device differs from the first image displayed by the first electronic device; the first layer is not displayed in the second image, thus ensuring that the generated second image does not leak user privacy information or infringe copyright. This solution, while protecting copyright or user privacy information, does not prevent operations such as screenshots and screen recordings. Furthermore, by prompting the user that the current interface is a secure interface, it helps the user understand the behavior, thereby improving the user experience.

[0189] This application also provides a secure display method, such as... Figure 11 As shown, in addition to the steps S401-S403 described above, the method may also include steps S408-S409.

[0190] S408, The first electronic device receives the user's second operation.

[0191] This second operation is used to activate the safety switch control.

[0192] Optionally, the safety switch control can be displayed on the screen of the first electronic device as a floating switch, or it can be a control in the settings page of the first electronic device, or it can be a control in the drop-down menu of the first electronic device.

[0193] For example, such as Figure 12 As shown in (a), when a user clicks the safety switch control, the mobile phone receives the user's click operation to turn on the safety switch. This embodiment of the application does not limit the specific action the user takes to turn on the safety switch control. Figure 12 (a) in the example is merely illustrative.

[0194] Optionally, the embodiments of this application do not limit the order in which the first electronic device receives the first operation and the second operation.

[0195] S409. In response to a second user operation, the first electronic device filters the third layer in the second image and generates a third image.

[0196] This third layer includes pop-up notifications. These pop-up notifications can be SMS messages, application notifications, or other notifications displayed in a pop-up format.

[0197] For example, when the user activates the safety switch control, the display interface of the first electronic device, as shown... Figure 12 As shown in (b) in the example, the first image displayed by the first electronic device includes a text message notification. This notification includes the user's salary information, which involves user privacy; the user does not want others to see their salary information. Figure 12 As shown in (c), in response to the user's screenshot operation, the mobile phone uses a first preset layer to replace or cover the first layer involving security in the first image, resulting in... Figure 12 The second image shown in (c) is as follows. Figure 12 As shown in (d) above, in response to the user's action of turning on the security switch, the phone filters the layer containing the SMS notification information in the second image to obtain... Figure 12 The third image shown in (d) does not include the SMS notification message containing the user's salary information.

[0198] For example, when the user activates the safety switch control, the display interface of the first electronic device, as shown... Figure 13 As shown in (a) in the example, the first image displayed by the first electronic device includes a text message notification. Figure 13 As shown in (b), in response to the user's screen recording operation, the mobile phone uses a first preset layer to replace or cover the first layer involving security in the first image, resulting in... Figure 13 The second image shown in (b) of the diagram. Figure 13 As shown in (c), in response to the user's action of turning on the security switch, the phone filters the layer containing the SMS notification information in the second image to obtain... Figure 13 The third image shown in (c) is shown in the image.

[0199] The display method provided in this embodiment, by enabling the security switch control, can further filter the pop-up notification information of the first electronic device, thereby preventing other users from seeing the user's SMS notification messages or application notification messages, and thus better protecting the user's privacy information.

[0200] Optionally, in the scenario where the first operation is a screenshot or screen recording, the steps S408-S409 above may further include the first electronic device displaying a third image. In the scenario where the first operation is a screen projection or screen sharing, the steps S408-S409 above may further include the first electronic device sending the third image to a second electronic device, the second electronic device receiving the third image, and the second electronic device displaying the third image.

[0201] This application also provides a secure display method, such as... Figure 14 As shown, the method includes steps S1401-S1405.

[0202] S1401, The first electronic device displays the first image.

[0203] S1402, The first electronic device receives the user's first operation.

[0204] The first operation can be a screenshot, screen recording, screen casting, or screen sharing operation.

[0205] S1403, The first electronic device determines whether the safety switch control is turned on.

[0206] Optionally, if the first electronic device receives a second operation from the user before step S1403, the first electronic device determines that the safety switch control is turned on. This second operation is used to turn on the safety switch control.

[0207] Optionally, if the first electronic device does not receive the user's second operation before step S1403, the first electronic device determines that the safety switch control is not turned on.

[0208] S1404. If the first electronic device determines that the safety switch control is not turned on, in response to the first operation, if the first electronic device determines that the first layer in the first image includes a safety symbol, the first electronic device replaces or covers the first layer with a first preset layer to generate a second image.

[0209] S1405. When the first electronic device determines that the safety switch control is turned on, in response to the first operation, if the first electronic device determines that the first layer in the first image includes a safety symbol, the first electronic device replaces or covers the first layer with a first preset layer, filters the third layer, and generates a third image.

[0210] This third layer includes pop-up notifications. These pop-up notifications can be SMS messages, application notifications, or other information displayed in a pop-up window.

[0211] It should be noted that the embodiments of this application do not limit the execution order of replacing or covering the first layer with the first preset layer and filtering the third layer in step S1405 of the above application. For example, the first electronic device can first replace or cover the first layer with the first preset layer and then filter the third layer. Alternatively, it can filter the third layer first and then replace or cover the first layer with the first preset layer. It can also simultaneously replace or cover the first layer with the first preset layer and filter the third layer. It is understood that the scheme of the first electronic device first replacing or covering the first layer with the first preset layer and then filtering the third layer is the same as the scheme of step S409 above.

[0212] Understandably, the difference between steps S1404 and S1405 lies in whether the safety switch control is enabled. When the safety switch control is enabled, the first electronic device not only needs to replace or overwrite the layer containing the safety label, but also needs to filter the pop-up notification information. When the safety switch control is disabled, the first electronic device only needs to replace or overwrite the layer containing the safety label.

[0213] It is understood that the specific implementation of the above steps S1401-S1405 can refer to the specific implementation of the foregoing embodiments.

[0214] The display method provided in this application embodiment involves a first electronic device receiving a first operation from a user and further determining whether a safety switch is on. If the first electronic device determines that the safety switch control is not on, in response to the first operation, if the first electronic device determines that the first layer in the first image includes a safety symbol, the first electronic device replaces or covers the first layer with a first preset layer to generate a second image. If the first electronic device determines that the safety switch control is on, in response to the first operation, if the first electronic device determines that the first layer in the first image includes a safety symbol, it replaces or covers the first layer with a first preset layer and filters the third layer to generate a third image. This ensures that the generated third image does not leak the user's privacy information or infringe on copyright, and this solution further protects the user's pop-up notification information from being seen by other users, improving the user experience.

[0215] Optionally, in the scenario where the first operation is a screenshot or screen recording, step S1404 may further include the first electronic device displaying a second image. In the scenario where the first operation is a screen projection or screen sharing, step S1404 may further include the first electronic device sending the second image to a second electronic device, the second electronic device receiving the second image, and the second electronic device displaying the second image.

[0216] Optionally, in the scenario where the first operation is a screenshot or screen recording, step S1405 may further include the first electronic device displaying a third image. In the scenario where the first operation is a screen projection or screen sharing, step S1405 may further include the first electronic device sending the third image to a second electronic device, the second electronic device receiving the third image, and the second electronic device displaying the third image.

[0217] This application also provides a secure display method, such as... Figure 15 As shown, the method includes steps S1501-S1503.

[0218] S1501, The first electronic device displays the first image.

[0219] S1502, The first electronic device receives the user's first operation.

[0220] The first operation is used to acquire the first image.

[0221] Optionally, the first operation may include a screenshot operation, a screen recording operation, a screen sharing operation, or a screen projection operation. It should be noted that, in this embodiment, the first operation may also be other operations for acquiring images displayed on an electronic device; this embodiment does not limit the specific form of the first operation.

[0222] S1503. In response to the user's first operation, if the first electronic device determines that the first control in the first image includes a security symbol, the first electronic device uses a second preset layer to cover the first control and generates a fourth image.

[0223] Optionally, the first electronic device covering the first control with a second preset layer may include the first electronic device adding a watermark, mosaic, or blurring to the first control.

[0224] For example, in response to a user's screenshot, screen recording, screen sharing, or screen projection operation, the first electronic device determines whether the controls included in the first image include a security identifier. Optionally, the first image may include multiple security controls, which may be controls in a single layer or controls in multiple layers.

[0225] Optionally, the security identifier can be a pre-configured security identifier for the application or system. For example, the application or system can pre-configure security identifiers for controls related to user privacy and security, such as account controls, password controls, and keyboard controls. Optionally, the security identifier can be LayoutParams.FLAG_SECURE.

[0226] Optionally, the second preset layer may include a prompt message to inform the user that the first image includes security information. This security information is security-related and may involve user privacy or copyright, etc. This application does not limit the specific content of the prompt message.

[0227] For example, the first electronic device uses a second preset layer to cover the first control and generate a fourth image, which may include: the first electronic device obtaining the position information of the first control in the first image; based on the position information, the first electronic device uses the second preset layer to cover the area where the first control is located and generates a fourth image.

[0228] Optionally, if the first electronic device determines that the first control in the first image includes a security symbol, a second preset layer can be used to cover the first control. For example, when the first electronic device generates the fourth image, the second preset layer can be located above the layer where the first control is located, so that the first control can be covered by the second preset layer.

[0229] In this implementation, because the first control is covered by the second preset layer, the generated fourth image does not display the first control; that is, the first control is invisible to the user, thus ensuring that the generated fourth image does not display user privacy information. This solution protects copyright or user privacy information without requiring manual editing by the user, improving the user experience.

[0230] Optionally, after step S1503 above, the method may further include: the first electronic device displaying a fourth image.

[0231] For example, such as Figure 16 As shown, in a screenshot scenario, the first image displayed on the phone is as follows: Figure 16 As shown in (a) in the example, the third-party application pre-configures security identifiers for the account control and password control. When the user triggers a screenshot operation, the mobile phone receives the screenshot operation and, in response to the screenshot operation, identifies the account control and password control in the first image, including the security identifiers. It then obtains the position information of the account control and password control in the first image and uses a second preset layer to cover the areas where the account control and password control are located, respectively, to generate a fourth image. This fourth image is shown below. Figure 16 As shown in (b) of the image, the account control and password control in the fourth image are both covered by the second preset layer.

[0232] For example, such as Figure 17 As shown, in a screen recording scenario, the first image displayed on the phone is as follows: Figure 17As shown in (a) above, the third-party application pre-configures security identifiers for the account control and password control. When the user triggers a screenshot, the phone recognizes the security identifiers in the account control and password control in the first image, obtains their location information in the first image, and uses a second preset layer to cover the areas where the account control and password control are located, respectively, to generate a fourth image. This fourth image is shown below. Figure 17 As shown in (b) of the image, the account control and password control in the fourth image are both covered by the second preset layer.

[0233] Optionally, after step S1503 above, the method may further include: the first electronic device sending a fourth image to the second electronic device, the second electronic device receiving the fourth image, and the second electronic device displaying the fourth image.

[0234] For example, such as Figure 18 As shown, in a screen mirroring scenario, the first image displayed on the mobile phone is as follows: Figure 18 Taking (a) as an example, the third-party application pre-configures security identifiers for the account and password controls. When the user triggers screen mirroring, the phone recognizes the security identifiers in the account and password controls in the first image, obtains their location information within the first image, and uses a second preset layer to cover the areas where the account and password controls are located, respectively, generating a fourth image. The phone sends the fourth image to the laptop, which receives and displays it. Figure 18 As shown in (b), the account control and password control in the fourth image displayed by the laptop are both covered by the second preset layer.

[0235] Understandably, in the display method provided in this application, when acquiring an image displayed by a first electronic device, if the first electronic device recognizes that a first control in the first image includes a security identifier, the first electronic device uses a second preset layer to cover the first control and generates a fourth image. Therefore, the generated fourth image does not display the information of the first control, thereby ensuring that the generated fourth image does not leak the user's privacy information. This solution can process the security control so that the information of the control cannot be seen by other users, thereby not only protecting user security, but also further improving the user experience due to the smaller area of ​​security processing.

[0236] Optional, such as Figure 19 As shown, when the first operation is a screenshot operation or a screen recording operation, the above display method may include steps S1504-S1505 in addition to the steps S1501-S1503 mentioned above.

[0237] S1504, The first electronic device receives the user's second operation.

[0238] This second operation is used to activate the safety switch control.

[0239] S1505, In response to the user's second operation, the first electronic device filters the third layer in the fourth image and generates the fifth image.

[0240] This third layer includes pop-up notifications. These pop-up notifications can be SMS messages, application notifications, or other information displayed in a pop-up window.

[0241] For example, when the user activates the safety switch control, the display interface of the first electronic device, as shown... Figure 20 As shown in (a) for example, the first image displayed by the first electronic device includes a text message notification. This notification includes the user's salary information, which involves user privacy; the user does not wish for others to see their salary information. Figure 20 As shown in (b), in response to the user's screenshot operation, the mobile phone uses a second preset layer to cover the account and password controls involving security in the first image, resulting in... Figure 20 The fourth image is shown in (b) above. In response to the user's activation of the security switch, the phone filters the layer containing the SMS notification information in the fourth image, resulting in the image shown below. Figure 20 The fifth image shown in (c) does not include the SMS notification message containing the user's salary information.

[0242] The display method provided in this embodiment, by enabling the security switch control, can further filter the pop-up prompts of the first electronic device, thereby preventing other users from seeing the user's SMS notifications or application notifications, and better protecting the user's privacy and security information.

[0243] Optionally, in the scenario where the first operation is a screenshot or screen recording, the steps S1504-S1505 above may further include: the first electronic device displaying the fifth image. In the scenario where the first operation is a screen projection or screen sharing, the steps S1504-S1505 above may further include: the first electronic device sending the fifth image to the second electronic device, the second electronic device receiving the fifth image, and the second electronic device displaying the fifth image.

[0244] This application also provides a secure display method, such as... Figure 21 As shown, the method includes steps S2101-S2105.

[0245] S2101, The first electronic device displays the first image.

[0246] S2102, The first electronic device receives the user's first operation.

[0247] The first operation can be a screenshot, screen recording, screen casting, or screen sharing operation.

[0248] S2103, The first electronic device determines whether the safety switch control is turned on.

[0249] Optionally, if the first electronic device receives the user's second operation before step S2103, the first electronic device determines that the safety switch control is turned on. This second operation is used to turn on the safety switch control.

[0250] Optionally, if the first electronic device does not receive the user's second operation before step S2103, the first electronic device determines that the safety switch control is not turned on.

[0251] S2104. If the first electronic device determines that the safety switch control is not turned on, in response to the first operation, if the first electronic device determines that the first control in the first image includes a safety symbol, the first electronic device uses a second preset layer to cover the first control and generates a fourth image.

[0252] S2105. When the first electronic device determines that the safety switch control is turned on, in response to the first operation, if the first electronic device determines that the first control in the first image includes a safety symbol, the first electronic device uses a second preset layer to cover the first control and filters the third layer to generate a fifth image.

[0253] This third layer includes pop-up notifications. These pop-up notifications can be SMS messages, application notifications, or other information displayed in a pop-up window.

[0254] It should be noted that the embodiments of this application do not limit the execution order of the first electronic device covering the first control with the second preset layer and filtering the third layer in step S2105 above. For example, the first electronic device can first cover the first control with the second preset layer and then filter the third layer. Alternatively, it can filter the third layer first and then cover the first control with the second preset layer. It can also simultaneously cover the first control with the second preset layer and filter the third layer. It is understood that the scheme of the first electronic device first covering the first control with the second preset layer and then filtering the third layer is the same as the scheme of step S1505 above.

[0255] Understandably, the difference between steps S2104 and S2105 is that, when the safety switch control is enabled, the first electronic device not only needs to cover the control including the safety symbol, but also needs to filter the pop-up prompt information. However, when the safety switch control is disabled, the first electronic device only needs to cover the control including the safety symbol.

[0256] It is understood that the specific implementation of the above steps S2101-S2105 can refer to the specific implementation of the foregoing embodiments.

[0257] The display method provided in this application embodiment involves a first electronic device receiving a first operation from a user and further determining whether a safety switch is on. If the first electronic device determines that the safety switch control is not on, in response to the first operation, if the first electronic device determines that the first control in the first image includes a safety icon, the first electronic device uses a second preset layer to cover the first control, generating a fourth image. If the first electronic device determines that the safety switch control is on, in response to the first operation, if the first electronic device determines that the first control in the first image includes a safety icon, it uses a second preset layer to cover the first control and filters the third layer, generating a fifth image. This ensures that the generated fifth image does not leak the user's privacy information or infringe on copyright, and further protects the user's pop-up notification information from being seen by other users, improving the user experience. Moreover, this solution, by processing the safety control, ensures that the control information is not seen by other users, thereby not only protecting user safety but also further improving the user experience due to the smaller area of ​​security processing.

[0258] Optionally, in the scenario where the first operation is a screenshot or screen recording, step S2104 may further include the first electronic device displaying a fourth image. In the scenario where the first operation is a screen projection or screen sharing, step S2104 may further include the first electronic device sending the fourth image to a second electronic device, the second electronic device receiving the fourth image, and the second electronic device displaying the fourth image.

[0259] Optionally, in the scenario where the first operation is a screenshot or screen recording, step S2105 may further include the first electronic device displaying the fifth image. In the scenario where the first operation is a screen projection or screen sharing, step S2105 may further include the first electronic device sending the fifth image to the second electronic device, the second electronic device receiving the fifth image, and the second electronic device displaying the fifth image.
