[0002] With the popularization of electronic devices, especially smart mobile terminals such as mobile phones, more and more applications are integrated into mobile phones, involving all aspects of people's daily lives, such as instant messaging, mobile payment, etc.

[0003] In some private scenarios, there is a need for privacy protection of electronic devices. For example, in a confidential meeting scenario, the user hopes that only basic communication function applications can be used on the electronic device, and other applications are disabled.

[0004] Currently, in confidential meeting scenarios, electronic devices meet the privacy protection requirements by disabling all applications other than basic communication functions in batches. However, when each other application in an electronic device is disabled, the electronic device will send a corresponding disablement broadcast message. If an electronic device disables a large number of other applications, the electronic device will send a large number of disablement broadcast messages, resulting in a broadcast storm during the privacy protection process.

[0057] The embodiments of the present application are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application and are not to be construed as limiting the present application.

[0058] The disclosure below provides many different embodiments or examples for implementing different structures of the present application. In order to simplify the disclosure of the present application, the components and settings of specific examples are described below. Of course, these are merely examples and are not intended to limit the present application. In addition, the present application may repeat reference numbers and / or reference letters in different examples. Such repetition is for the purpose of simplicity and clarity and does not in itself indicate the relationship between the various embodiments and / or settings discussed.

[0059] With the popularization of electronic devices, especially smart mobile terminals such as mobile phones, more and more applications are integrated into mobile phones, involving all aspects of people's daily lives, such as instant messaging, mobile payment, etc.

[0060] In some private scenarios, there is a need for privacy protection of electronic devices. For example, in a confidential meeting scenario, the user hopes that only basic communication function applications can be used on the electronic device, and other applications are disabled.

[0061] Currently, in confidential meeting scenarios, electronic devices meet the privacy protection requirements by disabling all applications other than basic communication functions in batches. However, when each other application in an electronic device is disabled, the electronic device will send a corresponding disablement broadcast message. If an electronic device disables a large number of other applications, the electronic device will send a large number of disablement broadcast messages, resulting in a broadcast storm during the privacy protection process.

[0062] In response to the above problems, the privacy protection method, privacy protection device, electronic device and storage medium provided in the embodiments of the present application, the privacy protection method is applied to the electronic device, and the electronic device includes an application layer and an application framework layer. When the application layer determines that the privacy mode of the electronic device is triggered, the batch suspension interface is called to batch suspend multiple applications to be suspended that are associated with the privacy mode. The application framework layer switches the application state of each suspended application from a visible state to an invisible state. The application framework layer sends a suspension broadcast message to the registered broadcast receiver of the application layer. The suspension broadcast message carries the invisible state of multiple suspended applications. When the privacy mode of the electronic device is triggered, multiple privacy protection applications are suspended in batches by calling the batch suspension interface, and the application state of each privacy protection application is modified to an invisible state, and only one suspension broadcast message is sent, so as to avoid sending the corresponding disable broadcast message separately when disabling each privacy protection application, thereby preventing the occurrence of broadcast storms during the privacy protection process.

[0063] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application.

[0064] The privacy protection method provided in the embodiments of the present application can be applied to electronic devices. Electronic devices can include various terminal devices, which can also be called terminals, user equipment (UE), mobile stations (MS), mobile terminals (MT), etc.

[0065] The terminal device may be a mobile phone, a robot vacuum, a drone, a smart TV, a wearable device, a personal digital assistant (PDA), a computer with wireless transceiver capabilities, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal used in industrial control, a wireless terminal used in self-driving, a wireless terminal used in remote medical surgery, a wireless terminal used in smart grids, a wireless terminal used in transportation safety, a wireless terminal used in smart cities, a wireless terminal used in smart homes, etc. The terminal device type is not limited here and can be set according to actual needs.

[0066] The software system of the electronic device can adopt a layered architecture, an event-driven architecture, a micro-kernel architecture, a microservice architecture, or a cloud architecture. The embodiment of the present application takes the Android system with a layered architecture as an example to illustrate the software structure of the electronic device.

[0067] See also Figure 1 , which shows a schematic diagram of the structure of the software system of an electronic device provided by one embodiment of the present application. The software system includes several layers, each with a clear role and division of labor, and communication between layers via software interfaces. In some embodiments, the Android system is divided into four layers: application layer, application framework layer, system library layer, and kernel layer, from top to bottom.

[0068] The application layer may include a series of applications. For example, the application layer may include a camera, a gallery, calls, wireless local area networks (WLAN), music, video, a media provider (MediaProvider), a FUSE (Filesystem in Userspace) file system, and the like.

[0069] The Media Provider is used to create multimedia files in the FUSE file system or access multimedia files in the FUSE file system. Each application in the application layer can create multimedia files in the FUSE file system through the Media Provider or access multimedia files in the FUSE file system through the Media Provider.

[0070] The FUSE file system is used to store the multimedia files that the media provider creates. Of course, in other embodiments, the FUSE file system also can be used to store other data.

[0071] The application framework layer provides an application programming interface (API) and programming framework for applications in the application layer. The application framework layer includes some predefined functions. For example, the application framework layer may include a window manager, content provider, resource manager, view system, package management service (PMS), and activity management service (AMS).

[0072] The window manager is used to manage window programs. The window manager can obtain the display size, determine whether there is a status bar, lock the screen, take screenshots, etc.

[0073] Content providers are used to store and retrieve data and make it accessible to applications. Data can include videos, images, audio, calls made and received, browsing history and bookmarks, phone books, etc.

[0074] The view system includes visual controls, such as those for displaying text and images. The view system is used to build applications. A display interface can consist of one or more views. For example, a display interface containing a text notification icon might include a view for displaying text and a view for displaying images.

[0075] The resource manager provides various resources for applications, such as localized strings, icons, images, layout files, video files, and so on.

[0076] The Package Manager service, as a package manager, is responsible for installing, managing, and uninstalling applications on Android devices. It scans designated directories on the system for files ending in APK, parses these files, and extracts all application information, storing it in packages.xml.

[0077] When a new application is installed, the package management service will identify all components of the application (such as activities, services, and broadcast receivers) and assign corresponding permissions to these components. At the same time, the package management service also monitors the status of installed applications to ensure the integrity and security of the applications.

[0078] The package management service also manages the application's DE (Device Encrypted) and CE (Credential Encrypted) data. The DE data key is only accessible after the system has performed a verified boot. The CE directory encrypts data using a key associated with a user's authentication method (e.g., pattern, password, etc.), which is only accessible after the user has authenticated.

[0079] The CE directory of the application may include the original uid of the application. The package management service is used to execute the file management method of this embodiment.

[0080] The Activity Management Service, as the activity manager service, is primarily responsible for managing and tracking the activity tasks and lifecycles of all applications. When an application is opened, the Activity Management Service starts the application's process and allocates processor resources and memory to it. When the application is no longer in the foreground or background, or when the system runs low on memory, the Activity Management Service terminates or kills the application's process.

[0081] System libraries may include Surface Manager, Media Libraries, Android Rruntime, etc.

[0082] The Android runtime consists of core libraries and a virtual machine (VM). The Android runtime is responsible for scheduling and management of the Android system. The core libraries consist of two parts: one containing the Java language's callable functions and the other the Android core library. The application layer and the application framework layer run in the VM. The VM executes the Java files in the application and framework layers as binary files. The VM is responsible for managing object lifecycles, stack management, thread management, security and exception management, and garbage collection.

[0083] The surface manager is used to manage the display subsystem and provide fusion of 2D and 3D layers for multiple applications.

[0084] The media library supports playback and recording of a variety of common audio and video formats, as well as static image files. The media library can support a variety of audio and video encoding formats, such as MPEG4, H.264, MP3, AAC, AMR, JPG, PNG, etc.

[0085] The kernel layer can include modules such as audio driver, display driver, Wi-Fi driver, Bluetooth driver, and sensor driver.

[0086] also, Figure 1 Also shown is a data layer related to the software system, which is used to store data preset by the user. For example, the data layer may pre-store data related to the privacy mode of the electronic device.

[0087] It is understandable that Figure 1 The layers in the illustrated software structure and the components contained in each layer do not constitute a specific limitation on the electronic device. In other embodiments of the present application, the electronic device may include more or fewer layers than shown, and each layer may include more or fewer components, and this application does not limit this.

[0088] It should be noted that although the embodiment of the present application is described using the Android system as an example, its basic principles are also applicable to Electronic devices using operating systems such as Harmony.

[0089] See also Figure 2 , which shows a flowchart of a privacy protection method provided by an embodiment of the present application. In a specific embodiment, the privacy protection method can be applied to electronic devices. Figure 2The process shown is described in detail, and the privacy protection method may include the following steps S110 to S130.

[0090] Step S110: When the application program layer determines that the privacy mode of the electronic device is triggered, the batch suspension interface is called to batch suspend multiple to-be-suspended applications associated with the privacy mode.

[0091] In the embodiment of the present application, the electronic device can be set with multiple scene modes, such as normal use mode, flight mode and privacy mode. In normal use mode, all applications of the electronic device can be used for normal communication. In flight mode, all applications of the electronic device cannot be used for communication. In privacy mode, some applications of the electronic device associated with the privacy mode (i.e., privacy protection applications) are invisible and unusable, such as Figure 3 As shown, it shows a schematic diagram of an application scenario in which an electronic device is in privacy mode.

[0092] The electronic device is equipped with a batch suspension interface that can be used to suspend multiple applications in batches. After suspension, the applications are in a suspended state. When the application layer determines that the privacy mode of the electronic device has been triggered, it can call the batch suspension interface to suspend multiple applications associated with the privacy mode in batches. After being suspended, the multiple applications are in a suspended state.

[0093] In some embodiments, the application layer is provided with a privacy mode application, and the user can click on the privacy mode application icon associated with the privacy mode application on the electronic device. The application layer perceives the user's click operation through the privacy mode application, and the application layer determines that the privacy mode of the electronic device is triggered.

[0094] In some embodiments, the application layer is provided with a privacy mode application, and the electronic device may further include a voice recognition module. The user can send a voice message carrying a privacy protection instruction within the voice collection range of the voice recognition module. The voice recognition module collects the voice information and performs voice recognition on the voice information to obtain the privacy protection instruction, and generates a trigger signal for triggering the privacy mode application according to the privacy protection instruction. The application layer perceives the trigger signal sent by the voice recognition module through the privacy mode application and determines that the privacy mode of the electronic device is triggered.

[0095] In some embodiments, the application layer is provided with a privacy mode application, and the user can send a privacy protection instruction to the client. The client receives and responds to the privacy protection instruction and sends a corresponding trigger instruction signal to the privacy mode application. The application layer perceives the trigger signal sent by the client through the privacy mode application and determines that the privacy mode of the electronic device is triggered.

[0096] The client can connect to the privacy mode application through the network and interact with the privacy mode application through the network.

[0097] The client can be any one of a mobile client (for example, a mobile phone client, a personal digital assistant (PDA) client, a tablet personal computer (Tablet PC) client, a laptop client, a smart watch client, a smart bracelet client or a wearable client, etc.) or a fixed client (for example, a desktop computer client, a smart panel client, etc.). The type of client is not limited here and can be set according to actual needs.

[0098] The network can be any one of a ZigBee network, a Bluetooth (BT) network, a Wireless Fidelity (Wi-Fi) network, a Thread network, a Long Range Radio (LoRa) network, a Low-Power Wide-Area Network (LPWAN), an infrared network, a Narrow Band Internet of Things (NB-IoT), a Controller Area Network (CAN), a Digital Living Network Alliance (DLNA) network, a Wide Area Network (WAN), a Local Area Network (LAN), a Metropolitan Area Network (MAN) or a Wireless Personal Area Network (WPAN), etc. The type of network is not limited here and can be set according to actual needs.

[0099] Step S120: the application framework layer switches the application state of each suspended application from a visible state to an invisible state.

[0100] In an embodiment of the present application, when the application layer determines that the privacy mode of the electronic device is triggered, it calls the batch suspension interface to batch suspend multiple applications to be suspended that are associated with the privacy mode. Then, it can send a first modification request to the application framework layer. The application framework layer receives and responds to the first modification request, and switches the application state of each suspended application from a visible state to an invisible state.

[0101] The application being in a visible state indicates that the application can be queried by the package management service, and the application being in an invisible state indicates that the application cannot be queried by the package management service.

[0102] In some embodiments, when the application layer determines that the privacy mode of the electronic device is triggered, it calls the batch suspension interface to batch suspend multiple applications to be suspended that are associated with the privacy mode, and then sends a first modification request to the application framework layer. The application framework layer receives and responds to the first modification request, modifies the application package information of each suspended application from visible application package information to invisible application package information through the package management service, and stores the invisible application package information in the initial package information file through the package management service to obtain a first target package information file, thereby realizing the modification of the application status of the suspended application to an invisible state by modifying the application package information of the suspended application to the invisible application package information.

[0103] The visible application package information may be used to indicate that the corresponding application is in a visible state, and the invisible application package information may be used to indicate that the corresponding application is in an invisible state.

[0104] In some embodiments, when the application layer determines that the privacy mode of the electronic device is triggered, it calls the batch suspension interface to batch suspend multiple applications to be suspended that are associated with the privacy mode, and then sends a first modification request to the application framework layer. The application framework layer receives and responds to the first modification request, modifies the application component information of each suspended application from visible application component information to invisible application component information through the package management service, and stores the invisible application component information in the initial package information file through the package management service to obtain a second target package information file, thereby realizing the modification of the application status of the suspended application to an invisible state by modifying the application component information of the suspended application to invisible application component information.

[0105] The visible application component information may be used to indicate that the corresponding application is in a visible state, and the invisible application component information may be used to indicate that the corresponding application is in an invisible state.

[0106] Step S130: The application framework layer sends a suspension broadcast message to the registered broadcast receiver of the application layer.

[0107] In an embodiment of the present application, after the application framework layer switches the application state of each suspended application from a visible state to an invisible state, it can send a suspension broadcast message to the registered broadcast receiver of the application layer. The suspension broadcast message can carry the invisible state of multiple suspended applications, thereby realizing that when the privacy mode of the electronic device is triggered, multiple privacy protection applications are suspended in batches by calling the batch suspension interface, and the application state of each privacy protection application is modified to an invisible state, and only one suspension broadcast message is sent, thereby avoiding sending corresponding disable broadcast messages separately when disabling each privacy protection application, thereby preventing the occurrence of broadcast storms during the privacy protection process.

[0108] In some embodiments, when a user needs to query an application in privacy mode, a first application query request can be sent to the application layer. The application layer receives the first application query request, responds to the first application query request, and sends a first query instruction to the application framework layer. The application framework layer receives and responds to the first query instruction, queries the first target application package information of the first target application from the first target package information file through the package management service, and sends the first target application package information to the application layer. The application layer receives the first target application package information returned by the application framework layer. The first target application package information is visible application package information, which realizes the determination of application visibility through the query of application package information by the package management service in privacy mode, which is beneficial for users to confirm whether the privacy protection application is in an invisible state based on the application visibility query result.

[0109] In some embodiments, when a user needs to start a second target application in privacy mode, a first start request can be sent to the application layer. The application layer receives the first start request and sends the first start request to the application framework layer. The application framework layer receives the first start request and responds to the first start request. The application status of the second target application is queried from the first target package information file through the activity management service, and the first application status query result is obtained. The second target application is controlled based on the first application status query result, thereby determining the application visibility through the query of the application package information by the activity management service in privacy mode, so that the application framework layer can prevent the invisible application from running based on the first application status query result.

[0110] The first launch request carries second target application information of the second target application, and the first launch request can be used to launch the second target application. The first application status query result includes a first visible status result indicating that the application package information of the second target application is visible application package information, and a first invisible status result indicating that the application package information of the second target application is invisible application package information.

[0111] When the first application status query results in the first visible state, the application framework layer uses the activity management service to start the second target application. When the first application status query results in the first invisible state, the application framework layer uses the activity management service to block the second target application. This ensures that when the application framework layer finds that the second target application's application status is invisible, it prevents the second target application from being started in a privacy scenario, ensuring the high reliability of privacy mode.

[0112] In some embodiments, when a user needs to query an application in privacy mode, a second application query request can be sent to the application layer. The application layer receives the second application query request, responds to the second application query request, and sends a second query instruction to the application framework layer. The application framework layer receives and responds to the second application query instruction, queries the third target application component information of the third target application from the second target package information file through the package management service, and sends the third target application component information to the application layer. The application layer receives the third target application component information returned by the application framework layer. The third target application package information corresponding to the third target application component information is visible application package information, which realizes the determination of application visibility through the query of application component information by the package management service in privacy mode, which is beneficial for users to confirm whether the privacy protection application is in an invisible state based on the application visibility query results.

[0113] In some embodiments, when a user needs to start a fourth target application in privacy mode, a second start request can be sent to the application layer. The application layer receives the second start request and sends the second start request to the application framework layer. The application framework layer receives the second start request and responds to the second start request. The application status of the fourth target application is queried from the second target package information file through the activity management service, and the second application status query result is obtained. The fourth target application is controlled based on the second application status query result, thereby determining the application visibility by querying the application component information through the activity management service in privacy mode, so that the application framework layer can prevent the invisible application from running based on the second application status query result.

[0114] The second launch request carries fourth target application information of the fourth target application, and the second launch request can be used to launch the fourth target application. The second application status query result can include a second visible status result indicating that the application package information of the fourth target application is visible application package information, and a second invisible status result indicating that the application package information of the fourth target application is invisible application package information.

[0115] When the second application status query results in the second visible state, the application framework layer uses the activity management service to start the fourth target application. When the second application status query results in the second invisible state, the application framework layer uses the activity management service to block the fourth target application. This ensures that when the application framework layer finds that the fourth target application's application status is invisible, it prevents the fourth target application from being started in a privacy scenario, ensuring the high reliability of privacy mode.

[0116] In some embodiments, when a user needs to exit privacy mode, a first exit privacy instruction can be sent to the application layer. The application layer receives and responds to the first exit privacy instruction, calls the batch suspension interface to unsuspend each suspended application associated with the privacy mode, and sends a second modification request to the application framework layer. The application framework layer receives and responds to the second modification request, switches the application state of each unsuspended application from an invisible state to a visible state, and sends an unsuspension broadcast message to the registered broadcast receiver of the application layer. The unsuspension broadcast message can carry the visible state of multiple unsuspended applications, so that when the electronic device exits privacy mode, multiple privacy protection applications can be unsuspended in batches by calling the batch suspension interface, and the application state of each privacy protection application can be modified to a visible state, and only one unsuspension broadcast message is sent, so as to avoid sending corresponding recovery broadcast messages separately when restoring the visibility of each privacy protection application, thereby preventing the occurrence of broadcast storms during the exit from privacy protection.

[0117] As an implementation method, the application package information of each unsuspended application is invisible application package information. The application layer can send a second modification request to the application framework layer. The application framework layer receives and responds to the second modification request, and modifies the application package information of each unsuspended application from invisible application package information to visible application package information through the package management service, and stores the visible application package information in the first target package information file through the package management service to obtain the third target package information file, thereby realizing the modification of the application status of the unsuspended application to a visible status by modifying the application package information of the unsuspended application to visible application package information.

[0118] As an implementation method, the application component information of each unsuspended application is invisible application component information. The application layer can send a second modification request to the application framework layer. The application framework layer receives and responds to the second modification request, and modifies the application component information of each unsuspended application from invisible application component information to visible application component information through the package management service, and stores the visible application component information in the second target package information file through the package management service to obtain a fourth target package information file, thereby realizing the modification of the application status of the unsuspended application to a visible status by modifying the application component information of the unsuspended application to visible application component information.

[0119] In one application scenario, such as Figure 4 As shown, the electronic device may include an application layer and an application framework layer, and the privacy inclusion method may include steps S1001 to S1014.

[0120] Step S1001: The application layer receives a user trigger operation for applying a privacy mode.

[0129] Step S1010: The application layer receives a first startup request.

[0130] Step S1011: forwarding the first startup request to the application framework layer.

[0131] Step S1012: the application framework layer responds to the first start request and queries the application status of the second target application from the packages.xml file through the activity management service to obtain a first application status query result.

[0132] The first application status query result includes a first visible status result and a first invisible status result.

[0133] When the first application status query result is a first visible status result, executing step S1013;

[0134] When the first application status query result is a first invisible status result, step S1014 is executed.

[0135] Step S1013: The application framework layer sends a first startup instruction to the application layer to start the second target application.

[0136] Step S1014: the application framework layer sends a first blocking instruction to the application layer to block the second target application from running.

[0137] In one application scenario, such as Figure 5 As shown, the electronic device may include an application layer and an application framework layer, and the privacy inclusion method may include steps S2001 to S2014.

[0138] Step S2001: The application layer receives a user trigger operation for applying a privacy mode.

[0139] Step S2002: The application layer responds to the triggering operation and calls a batch suspension interface to suspend multiple applications to be suspended that are associated with the privacy mode.

[0140] Step S2003: Send a first modification request to the application framework layer.

[0141] Step S2004: The application framework layer receives and responds to the first modification request, modifies the application component information of each suspended application from visible application component information to invisible application component information through the package management service, and stores the invisible application component information in the initial package information file (packages.xml file).

[0142] Step S2005: The application framework layer sends a suspension broadcast message to the registered broadcast receiver of the application.

[0143] Step S2006: The application program layer receives the second application query request.

[0144] Step S2007: The application layer responds to the second application query request and sends a second application query instruction to the application framework layer.

[0145] Step S2008: The application framework layer queries the third target application component information from the packages.xml file through the package management service according to the second query instruction.

[0146] Step S2009: The application framework layer sends the third target application component information to the application layer.

[0154] Step S2014: The application framework layer sends a second blocking instruction to the application layer to block the fourth target application from running.

[0155] The privacy protection method provided in this embodiment is applied to an electronic device, which includes an application layer and an application framework layer. When the application layer determines that the privacy mode of the electronic device is triggered, it calls a batch suspension interface to batch suspend multiple applications to be suspended that are associated with the privacy mode. The application framework layer switches the application state of each suspended application from a visible state to an invisible state. The application framework layer sends a suspension broadcast message to a registered broadcast receiver of the application layer. The suspension broadcast message carries the invisible state of multiple suspended applications. When the privacy mode of the electronic device is triggered, multiple privacy protection applications are suspended in batches by calling a batch suspension interface, and the application state of each privacy protection application is modified to an invisible state. Only one suspension broadcast message is sent, so as to avoid sending corresponding disable broadcast messages separately when disabling each privacy protection application, thereby preventing the occurrence of broadcast storms during the privacy protection process.

[0156] See also Figure 6 , which shows a flowchart of a privacy protection method provided by another embodiment of the present application. In a specific embodiment, the privacy protection method can be applied to electronic devices. Figure 6 The process shown is described in detail, and the privacy protection method may include the following steps S210 to S240.

[0157] Step S210: When the application layer determines that the privacy mode of the electronic device is triggered, it sends a privacy protection instruction to the application framework layer.

[0158] In this embodiment, when the application layer determines that the privacy mode of the electronic device is triggered, it can generate and send a privacy protection instruction to the application framework layer, and the application framework layer receives the privacy protection instruction sent by the application layer.

[0159] In some embodiments, the application layer is provided with a privacy mode application, and the user can click on the privacy mode application icon associated with the privacy mode application on the electronic device. The application layer perceives the user's click operation through the privacy mode application, and the application layer determines that the privacy mode of the electronic device is triggered.

[0160] In some embodiments, the application layer is provided with a privacy mode application, and the electronic device may further include a voice recognition module. The user can send a voice message carrying a privacy protection instruction within the voice collection range of the voice recognition module. The voice recognition module collects the voice information and performs voice recognition on the voice information to obtain the privacy protection instruction, and generates a trigger signal for triggering the privacy mode application according to the privacy protection instruction. The application layer perceives the trigger signal sent by the voice recognition module through the privacy mode application and determines that the privacy mode of the electronic device is triggered.

[0161] In some embodiments, the application layer is provided with a privacy mode application, and the user can send a privacy protection instruction to the client. The client receives and responds to the privacy protection instruction and sends a corresponding trigger instruction signal to the privacy mode application. The application layer perceives the trigger signal sent by the client through the privacy mode application and determines that the privacy mode of the electronic device is triggered.

[0162] Step S220: The application framework layer sends a privacy protection information acquisition instruction to the data layer according to the privacy protection instruction.

[0163] In this embodiment, after receiving the privacy protection instruction sent by the application layer, the application framework layer may send a privacy protection information acquisition instruction to the data layer according to the privacy protection instruction.

[0164] The data layer may pre-store a preset application list associated with the privacy mode, where the preset application list includes a plurality of privacy protection application information and a plurality of non-privacy protection application information.

[0165] Step S230: The data layer responds to the privacy protection information acquisition instruction and sends multiple privacy protection application information to the application framework layer.

[0166] In this embodiment, after receiving the privacy protection information acquisition instruction sent by the application framework layer, the data layer responds to the privacy protection information acquisition instruction, reads multiple privacy protection application information in the preset application list, and sends multiple privacy protection application information to the application framework layer.

[0167] Step S240: the application framework layer batch-closes multiple privacy protection applications according to the multiple privacy protection application information.

[0168] In this embodiment, the application framework layer can close multiple privacy protection applications based on multiple privacy protection application information. Each privacy protection application information corresponds to a privacy protection application. When the privacy mode of the electronic device is triggered, multiple privacy protection applications associated with the privacy mode are closed in batches without sending a shutdown broadcast message. This avoids sending corresponding disable broadcast information separately when disabling each privacy protection application, thereby preventing the occurrence of broadcast storms during the privacy protection process.

[0169] In some embodiments, when a user needs to query an application in privacy mode, a third application query request can be sent to the application layer. The application layer receives and responds to the third application query request and sends a third query instruction to the application framework layer. The application framework layer receives and responds to the third query instruction and sends a non-privacy protection information acquisition instruction to the data layer. The data layer receives and responds to the non-privacy protection information acquisition instruction, reads multiple non-privacy protection application information in a preset application list, and sends multiple non-privacy protection application information to the application framework layer. The application framework layer receives multiple non-privacy protection application information and forwards multiple non-privacy protection application information to the application layer, thereby realizing the query of non-privacy protection applications in privacy mode, which is beneficial for users to confirm whether the privacy protection application is in an invisible state based on the queried non-privacy protection application query results.

[0170] In some embodiments, when a user needs to start the fifth target application in privacy mode, a third start request can be sent to the application layer. The application layer receives the third start request and sends the third start request to the application framework layer. The application framework layer receives and responds to the third start request and sends a confirmation instruction carrying the fifth target application information of the fifth target application to the data layer. The data layer receives and responds to the confirmation instruction, confirms whether the fifth target application is a non-privacy protection application based on the fifth target application information, obtains a confirmation result, and sends the confirmation result to the application framework layer. The application framework layer receives the confirmation result returned by the data layer and controls the fifth target application based on the confirmation result, thereby realizing the query of whether the fifth target application is a non-privacy protection application according to the preset application list in privacy mode, so that the application framework layer prevents the fifth target application from being started when it is queried that the fifth target application is a privacy protection application.

[0171] Among them, the third startup request carries the fifth target application information of the fifth target application, the third startup request can be used to start the fifth target application, and the confirmation result may include a first confirmation result used to characterize that the fifth target application belongs to a non-privacy protection application, and a second confirmation result used to characterize that the fifth target application does not belong to a non-privacy protection application.

[0172] If the confirmation result is the first, the application framework layer uses the activity management service to start the fifth target application. If the confirmation result is the second, the application framework layer uses the activity management service to block the fifth target application from running. This ensures that if the application framework layer checks that the fifth target application is a privacy-protected application, it will block the fifth target application from being started in a privacy-protected scenario, ensuring the high reliability of the privacy mode.

[0173] In some embodiments, when the user needs to exit the privacy mode, a second exit privacy instruction can be sent to the application layer. The application layer receives and responds to the second exit privacy instruction and sends a recovery instruction to the application framework layer. The application framework layer receives and responds to the recovery instruction and batch-starts multiple privacy protection applications. This enables batch starting of multiple privacy protection applications when the electronic device exits the privacy mode, and does not send a recovery start broadcast message. This avoids sending a corresponding recovery start broadcast message separately when resuming each privacy protection application, thereby preventing the occurrence of a broadcast storm during the exit from privacy protection.

[0174] In one application scenario, such as Figure 7 As shown, the electronic device may include an application layer, an application framework layer, and a data layer, and the privacy inclusion method may include steps S3001 to S3019.

[0175] Step S3001: The application layer receives a user trigger operation for applying a privacy mode.

[0176] Step S3002: The application layer responds to the triggering operation and sends a privacy protection instruction to the application framework layer.

[0177] Step S3003: The application framework layer sends a privacy protection information acquisition instruction to the data layer according to the privacy protection instruction.

[0178] Step S3004: The data layer responds to the privacy protection information acquisition instruction and sends multiple privacy protection application information to the application framework layer.

[0179] Step S3005: The application framework layer batch-closes multiple privacy protection applications based on the multiple privacy protection application information.

[0180] Step S3006: The application program layer receives the third application query request.

[0181] Step S3007: The application layer responds to the third application query request and sends a third application query instruction to the application framework layer.

[0182] Step S3008: The application framework layer sends a non-privacy protection information acquisition instruction to the data layer according to the third query instruction.

[0183] Step S3009: The data layer responds to the non-privacy protection information acquisition instruction and reads the non-privacy protection application information in the preset application list.

[0184] Step S3010: Send multiple non-privacy protection application information to the application framework layer.

[0185] Step S3011: the application framework layer receives a plurality of non-privacy protection application information and forwards the plurality of non-privacy protection application information to the application layer.

[0186] Step S3012: The application layer receives the third startup request.

[0187] Step S3013: Forward the third startup request to the application framework layer.

[0188] Step S3014: the application framework layer responds to the third start request and sends a confirmation instruction carrying the fifth target application information of the fifth target application to the data layer.

[0189] Step S3015: The data layer responds to the confirmation instruction, confirms whether the fifth target application is a non-privacy protection application according to the fifth target application information, and obtains a confirmation result.

[0190] The confirmation result includes a first confirmation result and a second confirmation result.

[0191] Step S3016: The data layer sends the confirmation result to the application framework layer.

[0192] Step S3017: The application framework layer receives the confirmation result and controls the fifth target application according to the confirmation result.

[0193] When the confirmation result is the first confirmation result, execute step S3018;

[0194] When the confirmation result is the second confirmation result, step S3019 is executed.

[0195] Step S3018: The application framework layer sends a third startup instruction to the application layer to start the fifth target application.

[0196] Step S3019: The application framework layer sends a third blocking instruction to the application layer to prevent the fifth target application from running.

[0197] The privacy protection method provided in this embodiment is applied to an electronic device, which includes an application layer, an application framework layer, and a data layer. When the application layer determines that the privacy mode of the electronic device is triggered, it sends a privacy protection instruction to the application framework layer. The application framework layer sends a privacy protection information acquisition instruction to the data layer based on the privacy protection instruction. The data layer responds to the privacy protection information acquisition instruction and sends multiple privacy protection application information to the application framework layer. The application framework layer batch closes multiple privacy protection applications based on the multiple privacy protection application information, thereby realizing that when the privacy mode of the electronic device is triggered, multiple privacy protection applications associated with the privacy mode are batch closed without sending a shutdown broadcast message, avoiding sending corresponding disable broadcast information separately when disabling each privacy protection application, and preventing the occurrence of broadcast storms during the privacy protection process.

[0198] See also Figure 8 , which shows a privacy protection device 300 provided by an embodiment of the present application. The privacy protection device 300 can be applied to electronic devices.

[0206] In some embodiments, the second response module may include a first starting unit and a first preventing unit.

[0207] The first starting unit can be used to start the second target application through the activity management service when the first application status query result is the first visible status result; the first blocking unit can be used to block the second target application from running through the activity management service when the first application status query result is the first invisible status result.

[0208] In some implementations, the invisible switching module 320 may further include a second modifying unit and a second storage unit.

[0209] The second modification unit can be used for the application framework layer to modify the application component information of each suspended application from visible application component information to invisible application component information through the package management service.

[0212] In some implementations, the privacy protection device 300 may further include a second request sending module and a fourth response module.

[0218] The privacy protection method provided in this embodiment is applied to an electronic device, which includes an application layer and an application framework layer. When the application layer determines that the privacy mode of the electronic device is triggered, it calls a batch suspension interface to batch suspend multiple applications to be suspended that are associated with the privacy mode. The application framework layer switches the application state of each suspended application from a visible state to an invisible state. The application framework layer sends a suspension broadcast message to a registered broadcast receiver of the application layer. The suspension broadcast message carries the invisible state of multiple suspended applications. When the privacy mode of the electronic device is triggered, multiple privacy protection applications are suspended in batches by calling a batch suspension interface, and the application state of each privacy protection application is modified to an invisible state. Only one suspension broadcast message is sent, so as to avoid sending corresponding disable broadcast messages separately when disabling each privacy protection application, thereby preventing the occurrence of broadcast storms during the privacy protection process.

Electronic device 600 can also calculate the touch location based on the detection signal from pressure sensor 680A. In some embodiments, touch operations applied to the same touch location but with different touch intensities can correspond to different operation instructions. For example, when a touch operation with an intensity less than a first pressure threshold is applied to a short message application icon, a command to view short messages is executed. When a touch operation with an intensity greater than or equal to the first pressure threshold is applied to a short message application icon, a command to create a new short message is executed.
