BACKGROUND

With development of terminal device technologies and transformations such as smart homes, smart travel, and smart office, consumers use terminal devices more frequently. As terminal device interconnections increase, security risks of connections between terminal devices also increase. How to ensure normal use of functions of interconnected devices and prevent the devices from being maliciously attacked is to be further studied.

SUMMARY

This application provides a device security processing method and an electronic device, so that a local device can further receive a user operation to eliminate a security risk on the local device or another interconnected device, to improve security of the local device or the another interconnected device, ensure normal use of the device, and prevent leakage of user privacy.

According to a first aspect, this application provides a device security processing system. The system includes a first electronic device and a second electronic device. The first electronic device is configured to display a first user interface or first prompt information, where a security risk item that exists on the second electronic device is displayed on the first user interface, or the first prompt information indicates that a security risk item exists on the second electronic device, and the security risk item that exists on the second electronic device is related to user privacy. The first electronic device is further configured to receive a first operation of a user on the first user interface or the first prompt information, where the first operation is used to eliminate the security risk item that exists on the second electronic device. The first electronic device is further configured to send a first instruction to the second electronic device after receiving the first operation. The second electronic device is configured to: after receiving the first instruction, eliminate the security risk item that exists on the second electronic device.

In this way, the user can view, on the first electronic device, the security risk item that exists on the second electronic device. When it is inconvenient for the user to perform an operation on the second electronic device, the first electronic device can receive a user operation to eliminate the security risk item that exists on the second electronic device. This ensures device security of the second electronic device, and avoids leakage of user data on the second electronic device.

With reference to the first aspect, in a possible implementation, the first electronic device is further configured to: after sending the first instruction to the second electronic device, stop displaying, on the first user interface, the security risk item that exists on the second electronic device, or stop displaying the first prompt information.

In this way, after the first electronic device sends the first instruction to the second electronic device, the first electronic device can stop displaying a security risk event that exists on the second electronic device.

With reference to the first aspect, in a possible implementation, the second electronic device is further configured to send a second instruction to the first electronic device after eliminating the security risk item that exists on the second electronic device. The first electronic device is further configured to: after receiving the second instruction, stop displaying, on the first user interface, the security risk item that exists on the second electronic device, or stop displaying the first prompt information.

In this way, after the first electronic device determines that the second electronic device has eliminated a security risk event that exists on the second electronic device, the first electronic device can stop displaying the security risk event that exists on the second electronic device.

With reference to the first aspect, in a possible implementation, the security risk item that exists on the second electronic device includes one or more items. The first operation is an operation of eliminating a first item in the security risk item that exists on the second electronic device. The second electronic device is specifically configured to: after receiving the first instruction, eliminate the first item that exists on the second electronic device.

In this way, the first electronic device can receive user operations to eliminate, one by one, security risk items that exist on the second electronic device, so that the user selectively eliminates one or more security risk items that exist on the second electronic device.

With reference to the first aspect, in a possible implementation, the security risk item that exists on the second electronic device includes one or more items. The first operation is an operation of eliminating all the items in the security risk item that exists on the second electronic device. The second electronic device is specifically configured to: after receiving the first instruction, eliminate all the items that exist on the second electronic device.

In this way, the first electronic device can receive the user operation to “one-touch eliminate” all security risk items that exist on the second electronic device, which reduces a user operation, and is convenient and quick.

With reference to the first aspect, in a possible implementation, the first electronic device is further configured to display a second user interface before displaying the first user interface, where the second user interface includes a device option of the first electronic device and a device option of the second electronic device, the device option of the first electronic device includes a security level indicator of the first electronic device, and the device option of the second electronic device includes a security level indicator of the second electronic device; and the security level indicator indicates a security status of an electronic device, and the security status includes any one of a high risk, a medium risk, a low risk, and no risk. The first electronic device is specifically configured to: receive and respond to a second operation of the user on the device option of the second electronic device on the second user interface, and display the first user interface.

Optionally, if the security status of the first electronic device is different from the security status of the second electronic device, the security level indicator of the first electronic device is different from the security level indicator of the second electronic device.

In this way, the first electronic device can display the security status of the first electronic device and/or a security status of another device, so that the user can monitor the security statuses of the first electronic device and the second electronic device, and manage and control an electronic device that is in a poor security state.

With reference to the first aspect, in a possible implementation, the first electronic device is further configured to: receive and respond to a third operation of the user on the second user interface, and display a third user interface, where a security risk item that exists on the first electronic device and the security risk item that exists on the second electronic device are displayed on the third user interface. The first electronic device is further configured to receive a fourth operation of the user on the third user interface, where the fourth operation is used to eliminate the security risk item on the first electronic device and the security risk item that exists on the second electronic device. The first electronic device is further configured to: in response to the fourth operation, eliminate the security risk item that exists on the first electronic device, and send a third instruction to the second electronic device. The second electronic device is further configured to: after receiving the third instruction, eliminate the security risk item that exists on the second electronic device.

Optionally, the user may perform operations on the first electronic device to eliminate, one by one, security risk items that exist on both the first electronic device and the second electronic device. For example, an application 1 and an application 2 exist on both the first electronic device and the second electronic device, and the application 1 and the application 2 are malicious applications. The user may perform an operation on the first electronic device to “one-touch uninstall” the application 1 that exists on both the first electronic device and the second electronic device. The first electronic device may further receive a user operation to “one-touch uninstall” the application 2 that exists on both the first electronic device and the second electronic device.

Optionally, the user may perform an operation on the first electronic device to “one-touch” eliminate all security risk items that exist on both the first electronic device and the second electronic device. For example, an application 1 and an application 2 exist on both the first electronic device and the second electronic device, and the application 1 and the application 2 are malicious applications. The user may perform an operation on the first electronic device to “one-touch uninstall” the application 1 and the application 2 that exist on both the first electronic device and the second electronic device. An operation is simple.

With reference to the first aspect, in a possible implementation, the first electronic device is specifically configured to: display second prompt information after receiving the first operation, where the second prompt information includes a first control, and the second prompt information indicates whether to eliminate the security risk item that exists on the second electronic device; and receive and respond to a fifth operation on the first control, and send the first instruction to the second electronic device.

In this way, before the second electronic device eliminates the security risk item that exists on the second electronic device, the first electronic device can display prompt information, to avoid a misoperation of the user.

Optionally, the prompt information may alternatively be displayed on the second electronic device.

With reference to the first aspect, in a possible implementation, the second electronic device is further configured to send the second instruction to the first electronic device after eliminating the security risk item that exists on the second electronic device. The first electronic device is further configured to display third prompt information after receiving the second instruction, where the third prompt information includes a second control, and the third prompt information indicates whether to cancel elimination of the security risk item that exists on the second electronic device. The first electronic device is specifically configured to: after receiving and responding to a sixth operation on the second control, determine to eliminate the security risk item that exists on the second electronic device.

In this way, after the second electronic device eliminates the security risk item that exists on the second electronic device, the first electronic device can display prompt information, to notify the user of an operation that has been performed by the second electronic device, and can provide an option for the user to cancel the operation that has been performed by the second electronic device.

Optionally, the prompt information may alternatively be displayed on the second electronic device.

DESCRIPTION OF EMBODIMENTS

The following clearly describes the technical solutions in embodiments of this application in detail with reference to the accompanying drawings. In the descriptions of embodiments of this application, “/” indicates “or” unless otherwise specified. For example, A/B may indicate A or B. The term “and/or” in this specification describes merely an association relationship between associated objects, and indicates that three relationships may exist. For example, A and/or B may indicate the following three cases: Only A exists, both A and B exist, and only B exists. In addition, in the descriptions of embodiments of this application, “a plurality of” means two or more.

The following terms “first” and “second” are merely intended for a purpose of description, and shall not be understood as an indication or implication of relative importance or implicit indication of a quantity of indicated technical features. Therefore, a feature limited by “first” or “second” may explicitly or implicitly include one or more features. In the descriptions of embodiments of this application, unless otherwise specified, “a plurality of” means two or more than two.

The term “user interface (user interface, UI)” in the following embodiments of this application is a medium interface for interaction and information exchange between an application or an operating system and a user, and implements conversion between an internal form of information and a form that can be accepted by the user. The user interface is usually in a representation form of a graphical user interface (graphical user interface, GUI), which is a user interface that is displayed in a graphical manner and that is related to a computer operation. The user interface may be a visual interface element like a text, an icon, a button, a menu, a tab, a text box, a dialog box, a status bar, a navigation bar, or a widget that is displayed on a display of an electronic device.

Before embodiments of this application are described, technical terms in embodiments of this application are first explained.

1. Security Risk

A security risk on an electronic device means that an application installed on the electronic device has a risk, or some information received on the electronic device has a risk, and the application or the information may steal personal data of a user.

For example, some applications may obtain information such as a call record, contact information, application use data, an account and a password, and property that are stored on the electronic device, causing personal information leakage. For another example, some information received on the electronic device may also steal the personal data of the user, causing personal information leakage.

For example, a messaging application receives a spam SMS message. After the user taps the spam SMS message, a server that sends the spam SMS message may steal the personal data of the user on the electronic device, causing personal information leakage of the user.

2. Device Security Status

An electronic device may score a security coefficient of the electronic device based on factors such as types and a quantity of some applications or some information existing on the electronic device, and a quantity of obtained information, and use an obtained score as a security status of the electronic device. The security status of the electronic device may be classified into a plurality of different levels such as a high risk, a medium risk, a low risk, and no risk.

Optionally, the electronic device may also score the security coefficient of the electronic device, to obtain different scores, for example, 100 points, 80 points, and 60 points. The scores may correspond to the security status levels of the electronic device. For example, when a security coefficient score of the device is 100 points, a corresponding security status level of the device is the “no risk”. When a security coefficient score of the device ranges from 70 points to 100 points, a corresponding security status level of the device is the low risk. When a security coefficient score of the device ranges from 50 points to 70 points, a corresponding security status level of the device is the medium risk. When a security coefficient score of the device is less than 50 points, a corresponding security status level of the device is the high risk.

It should be noted that the correspondence between the security coefficient score of the device and the security status level of the device is merely used to explain this application. This is not limited in embodiments of this application.

A security coefficient score obtained when the security status of the electronic device is the high risk is less than a security coefficient score obtained when the security status of the electronic device is the medium risk. The security coefficient score obtained when the security status of the electronic device is the medium risk is less than a security coefficient score obtained when the security status of the electronic device is the low risk. The security coefficient score obtained when the security status of the electronic device is the low risk is less than a security coefficient score obtained when the security status of the electronic device is the “no risk”.

The security status is not limited to the foregoing several levels. In another embodiment, the security status of the electronic device may alternatively be classified into more levels, or the security status of the electronic device may be classified into levels different from the foregoing levels. This is not limited in embodiments of this application.

Optionally, based on the security status that is of the electronic device and that includes different levels, the electronic device may display different prompt information, to indicate a user to improve the security status of the electronic device, so as to avoid personal information leakage of the user.

Specifically, when the security status of the electronic device is the high risk, the electronic device may display prompt information “Optimize now”. When the security status of the electronic device is the medium risk, the electronic device may display prompt information “Optimize in time”. When the security status of the electronic device is the low risk, the electronic device may display prompt information “Optimization suggested”. When the security status of the electronic device is the “no risk”, the electronic device may display prompt information “Good state”

3. Security Function

The WLAN security detection function is used to detect whether a nearby WLAN is a secure WLAN.

The mobile guard function is used to detect whether a nearby base station is a secure base station.

For the pure mode enabling function, after a pure mode function is enabled on the electronic device, the electronic device can intercept an application to be automatically installed, to avoid installing a spam application without knowledge of a user.

For the secure input method enabling function, after a secure input method function is enabled on the electronic device, when the user inputs a password on the electronic device, the electronic device automatically switches to a secure keyboard, to avoid password leakage.

After the verification code protection function is enabled on the electronic device, the verification code protection function is used to prevent some applications from obtaining a verification code.

After the payment protection function is enabled on the electronic device, the payment protection function is used to protect payment security, for example, when there is a risk, indicate the user whether to continue payment.

After the find device function is enabled on the electronic device, the find device function is used to, when the device is lost, quickly locate and track the lost device, and receive a user operation to remotely erase data on the lost device, to prevent leakage of the data on the lost device.

For the lock screen password enabling function, after the lock screen password enabling function is enabled on the electronic device, after the electronic device turns off a screen and then the electronic device turns on the screen again, the user needs to input a lock screen password to enter a user interface displayed on the electronic device before the screen is locked.

It should be noted that the security function on the electronic device may further include another function. This is not limited in embodiments of this application.

The device discovery capability is used by the electronic device 100 to discover the interconnected device.

The device security event storage capability is used to store a device security event that is generated in a specific period of time and a security capability supported by the device, which are on the electronic device 100 or sent by the another interconnected device.

The device security risk computing capability is used by the electronic device 100 to obtain a device security risk level of the electronic device 100 through computing based on the device security event on the electronic device 100, or the electronic device 100 may also obtain a device security risk level of the another interconnected device through computing based on the device security event sent by the another interconnected device. The device security risk computing capability is further used to display, based on the security risk that exists on the electronic device 100 and/or a security risk that exists on an electronic device 200, a related suggestion for eliminating the security risk.

The device security function management capability is used by the electronic device 100 to display a security function supported by the electronic device 100, or display, based on the device security capability sent by the another interconnected device, a security function supported by the another interconnected device. The electronic device 100 may also receive an operation of the user, to control the security function of the electronic device 100 or control the security function of another interconnected device, for example, control enabling or disabling of the security function.

The Android runtime includes a kernel library and a virtual machine. The Android runtime is responsible for scheduling and management of the Android system.

The kernel library includes two parts: a function that needs to be invoked in a Java language, and a kernel library of Android.

The application layer and the application framework layer run on the virtual machine. The virtual machine executes Java files at the application layer and the application framework layer as binary files. The virtual machine is used to perform functions such as object lifecycle management, stack management, thread management, security and exception management, and garbage collection.

The system library may include a plurality of functional modules, such as a surface manager (surface manager), a media library (Media Library), a three-dimensional graphics processing library (for example, an OpenGL ES), and a 2D graphics engine (for example, an SGL).

The surface manager is used to manage a display subsystem and provide fusion of 2D and 3D layers for a plurality of applications.

The media library supports playback and recording in a plurality of commonly used audio and video formats, a static image file, and the like. The media library may support a plurality of audio and video encoding formats such as MPEG-4, H.264, MP3, AAC, AMR, JPG, and PNG.

The three-dimensional graphics processing library is used to implement three-dimensional graphics drawing, image rendering, composition, layer processing, and the like. The 2D graphics engine is a drawing engine for 2D drawing.

The kernel layer is a layer between hardware and software. The kernel layer includes at least a display driver, a camera driver, an audio driver, and a sensor driver.

The following describes an example of a working procedure of the software and the hardware of the electronic device 100 with reference to a photographing scenario.

When the touch sensor 180K receives a touch operation, a corresponding hardware interrupt is sent to the kernel layer. The kernel layer processes the touch operation into an original input event (including information such as touch coordinates and a time stamp of the touch operation). The original input event is stored at the kernel layer. The application framework layer obtains the original input event from the kernel layer, and identifies a control corresponding to the input event. For example, the touch operation is a single-tap touch operation, and a control corresponding to the single-tap operation is a control of a camera application icon. A camera application invokes an interface at the application framework layer, to start the camera application. Then, the camera driver is started by invoking the kernel layer, and a static image or a video is captured through the camera 193.

FIG. 4A is a diagram of an example of interaction between a plurality of functional modules of an electronic device 100.

As shown in FIG. 4A, a device discovery module is used by the electronic device 100 to discover an electronic device that currently establishes a communication connection to the electronic device 100.

If no electronic device 100 currently establishes a communication connection, the electronic device 100 may display only a device security status of the electronic device 100, a security risk that exists on the electronic device 100, a security function supported by the electronic device 100, a security event on the electronic device 100, and the like.

If there is currently another device that establishes a communication connection to the electronic device 100, the electronic device 100 may display a device security status of the electronic device 100, a security risk that exists on the electronic device 100, a security function supported by the electronic device 100, and a security event on the electronic device 100, and may further display a device security status of another device that establishes a communication connection to the electronic device 100, the security risk that exists on the electronic device 100, the security function supported by the electronic device 100, the security event on the electronic device 100, and the like.

Specifically, another electronic device (for example, an electronic device 200) establishes a communication connection to the electronic device 100. In a possible implementation, the electronic device 200 may send, to the electronic device 100, information such as a security function supported by the electronic device 200 and a security event generated by the electronic device 200 in a specific period of time. After receiving the information such as the security function supported by the electronic device 200 and the security event generated by the electronic device 200 in the specific period of time sent by the electronic device 200, the electronic device 100 determines, via a device security risk computing capability module based on information such as the security event generated by the electronic device 200 in the specific period of time, a device security status of the electronic device 200 and a security risk that exists on the electronic device 200. In another possible implementation, the electronic device 200 may locally determine, based on information such as a security event generated by the electronic device 200 in a specific period of time, a device security status of the electronic device 200 and a security risk that exists on the electronic device 200. Then, the electronic device 200 sends, to the electronic device 100, a security function supported by the electronic device 200, the device security status of the electronic device 200, and the security risk that exists on the electronic device 200.

The device security risk computing module may also determine, based on information such as a security event generated by the electronic device 100 in the specific period of time, the device security status of the electronic device 100 and the security risk that exists on the electronic device 100.

After the device security risk computing module determines the device security status of the electronic device 100 and the security risk that exists on the electronic device 100, and/or the device security status of the electronic device 200 and the security risk that exists on the electronic device 200, the device security risk computing module may display the device security status of the electronic device 100 and the device security status of the electronic device 200 via the device security status display module, and may also display, via the device security risk and security risk elimination suggestion display module, the security risk that exists on the electronic device 100 and the security risk that exists on the electronic device 200. The device security risk computing module may also display a corresponding security risk elimination suggestion via the device security risk and security risk elimination suggestion display module based on the security risk that exists on the electronic device 100 and/or the security risk that exists on the electronic device 200.

After obtaining the security event generated by the electronic device 100 in the specific period of time and the security event generated by the electronic device 200 in the specific period of time, a device security event storage module stores, on the electronic device 100, the security event generated by the electronic device 100 in the specific period of time and the security event generated by the electronic device 200 in the specific period of time. In addition, the device security event storage module may separately display, via the device security event recording module, the security events generated by the electronic device 100 and the electronic device 200 in the specific period of time.

After obtaining the security capability supported by the electronic device 100 and a security capability supported by the electronic device 200, a device security function management module may separately display, via a device security display module, the security capability supported by the electronic device 100 and the security capability supported by the electronic device 200.

Optionally, the electronic device 100 may also receive an operation of the user, to control enabling or disabling of one or more security functions on the electronic device 100 and the electronic device 200, to improve security of personal information on the electronic device 100 and the electronic device 200.

Optionally, after the electronic device 200 is disconnected from the electronic device 100, the electronic device 100 no longer displays the security status of the electronic device 200 and the security risk that exists on the electronic device 200.

With reference to UI diagrams, the following describes in detail a device security processing method provided in embodiments of this application.

It should be noted that the following UI diagrams are merely used to explain this application. During actual application, a user interface may be in a different display form. This is not limited in embodiments of this application.

In some embodiments, after an electronic device 100 establishes a communication connection to another electronic device (for example, an electronic device 200), and the electronic device 100 detects that a security risk exists on the electronic device 200, the electronic device 200 may display a pop-up window to indicate a user whether to eliminate the security risk that exists on the electronic device 100. For example, as shown in FIG. 4B, the electronic device 100 may display prompt information 450. The prompt information 450 indicates the user whether to eliminate the security risk that exists on the electronic device 200. The electronic device 100 may receive an input operation (for example, a single tap) of the user on a control 460 in the prompt information 450. In a possible implementation, in response to the input operation of the user, the electronic device 100 may first display, for viewing by the user, the security risk that exists on the electronic device 200, and then the electronic device 100 receives a user operation to eliminate the security risk that exists on the electronic device 200. In another possible implementation, the electronic device 100 may first eliminate the security risk that exists on the electronic device 200, and then display prompt information to indicate the user to view which security risk is eliminated. The electronic device 100 may also receive a user operation to cancel elimination of the eliminated security risk that exists on the electronic device 200. For details, refer to embodiments shown in FIG. 6A to FIG. 6N and FIG. 7A to FIG. 7G. Details are not described in this embodiment of this application.

The electronic device 100 may alternatively receive an input operation (for example, a single tap) of the user on a control 470 in the prompt information 450. In response to the input operation of the user, the electronic device 100 ignores the prompt, that is, does not view the security risk that exists on the electronic device 200 and does not eliminate the security risk that exists on the electronic device 200.

In another embodiment, after an electronic device 100 establishes a communication connection to another electronic device (for example, an electronic device 200), and the electronic device 100 detects that a security risk exists on the electronic device 200, the electronic device 200 may indicate a user in a service suggestion display area whether to eliminate the security risk that exists on the electronic device 100. For example, as shown in FIG. 4C, the electronic device 200 may display a service card 480 in the service suggestion display area. The service card 480 indicates, to the user, the security risk that exists on the electronic device 200 and indicates the user whether to eliminate the security risk. The electronic device 100 may receive an input operation (for example, a single tap) of the user on a control 490 in the service card 480. In a possible implementation, in response to the input operation of the user, the electronic device 100 may first display, for viewing by the user, the security risk that exists on the electronic device 200, and then the electronic device 100 receives a user operation to eliminate the security risk that exists on the electronic device 200. In another possible implementation, the electronic device 100 may first eliminate the security risk that exists on the electronic device 200, and then display prompt information to indicate the user to view which security risk is eliminated. The electronic device 100 may also receive a user operation to cancel elimination of the eliminated security risk that exists on the electronic device 200. For details, refer to embodiments shown in FIG. 6A to FIG. 6N and FIG. 7A to FIG. 7G. Details are not described in this embodiment of this application.

The electronic device 100 may alternatively receive an input operation (for example, a single tap) of the user on a control 4110 in the service card 480. In response to the input operation of the user, the electronic device 100 ignores the prompt, that is, does not view the security risk that exists on the electronic device 200 and does not eliminate the security risk that exists on the electronic device 200.

In addition to the prompt information 450 and the service card 480 that are displayed in FIG. 4B and FIG. 4C, the electronic device 100 may alternatively display prompt information in a drop-down notification bar, to indicate the user whether to view and eliminate the security risk that exists on the electronic device 200.

Optionally, when a security risk exists on the electronic device 100, the electronic device 100 may also indicate, to the user based on the embodiments shown in FIG. 4A and FIG. 4B, the security risk that exists on the electronic device 100. Details are not described again in this embodiment of this application.

In another embodiment, an electronic device 100 may alternatively view, in a settings application, a security risk that exists on the electronic device 100 and a security risk that exists on an electronic device that establishes a connection to the electronic device 200.

As shown in FIG. 5E, in response to the slide operation of the user, the electronic device 100 displays a user interface 503. The user interface 503 further shows security functions supported by the electronic device 100, for example, TrustSpace and a scam guard function. The electronic device 100 may receive a user operation to enable one or more security functions, to improve a security capability of the electronic device 100.

As shown in FIG. 5E, the user interface 503 further shows security protection suggestions. The security protection suggestions are security protection suggestions for the electronic device 100. For example, the security protection suggestions may include the following: “The “Perfecto pinball” application installed on the electronic device 100 is detected as a virus application. It is suggested that you uninstall the application or move the application to the application security center now “. “The “BaoFeng player” application installed on the electronic device 100 is detected as a virus application. It is suggested that you uninstall the application or move the application to the application security center now “. “The “Quick loan” application installed on the electronic device 100 is detected as a scam application. Uninstallation suggested “. The security protection suggestions are used to indicate, to the user, security risks that exist on the electronic device 100, and indicate the user to eliminate, using specific methods, the security risks that exist on the electronic device 100.

As shown in FIG. 5E, the electronic device 100 may continue to receive a slide operation (for example, an upward slide operation) performed by the user on the user interface 502. In response to the slide operation of the user, the electronic device 100 may display other content that is not displayed.

In response to the slide operation of the user, the electronic device 100 may display a security event record generated by the electronic device 100 in a specific period of time and/or a security event record generated, in the specific period of time, by the another device interconnected to the electronic device 100. The security event record includes but is not limited to a security event type, a time point at which a security event occurs, content of the security event, and the like.

When there is another device that establishes a communication connection to the electronic device 100, the electronic device 100 may display the security event records generated, in the specific period of time, by the electronic device 100 and the another device interconnected to the electronic device 100.

When there is no another device that establishes a communication connection to the electronic device 100, the electronic device 100 may display only the security event record generated by the electronic device 100 in the specific period of time.

For example, as shown in FIG. 5F, in response to the slide operation of the user, the electronic device 100 displays a user interface 504. The security event records generated, in the specific period of time, by the electronic device 100 and the another device interconnected to the electronic device 200 are displayed on the user interface 504. For example, the security event records may be as follows: 4:48 pm today, a security event type being “Harassment blocking”, and specific content being “123123321232 was blocked three times”; 08:48 am today, a security event type being “System root status”, and specific content being “The device was rooted”; 9:17 pm yesterday, a security event type being “Virus scanning and removal”, and specific content being “2 virus applications were found”; 09:00 pm yesterday, a security event type being “Virus scanning and removal”, and specific content being “2 malicious applications were found”; 8:17 pm yesterday, a security event type being “Virus scanning and removal”, and specific content being “1 risky application was found”; and 9:48 am yesterday, a security event type being “Lock screen password”, and specific content being “The lock screen password was set”.

Optionally, a security protection suggestion for the electronic device 100 and/or a security protection suggestion for the another device interconnected to the electronic device 100 may alternatively be displayed on the user interface 503.

When there is another device that establishes a communication connection to the electronic device 100, the electronic device 100 may display the security protection suggestions for the electronic device 100 and the another device interconnected to the electronic device 100.

When there is no another device that establishes a communication connection to the electronic device 100, the electronic device 100 may display only the security protection suggestion for the electronic device 100.

As shown in FIG. 5G, the user interface 503 further includes a “one-touch eliminate” control 512. The electronic device 100 may receive an input operation (for example, a single tap) of the user on the “one-touch eliminate” control 512. In response to the input operation of the user, the electronic device 100 may “one-touch” eliminate the security risk that exists on the electronic device 100 and/or a security risk that exists on the electronic device 200. This reduces a user operation.

In response to the input operation of the user on the “one-touch eliminate” control 512, the electronic device 100 may display a prompt bar 513 shown in FIG. 5H.

The prompt bar 513 includes prompt information “Are you sure you want to uninstall the Perfecto pinball application and the BaoFeng player application on the electronic device 200, enable the USB debugging function on the electronic device 200, and uninstall the Quick loan application on the electronic device 100?” The prompt bar 513 further includes a cancel option and a confirm option. In this way, a misoperation of the user can be prevented.

The electronic device 100 may receive an input operation (for example, a single tap) of the user on the cancel option in the prompt bar 513. In response to the input operation of the user, the electronic device 100 suspends eliminating the security risks that exist on the electronic device 100 and the electronic device 200. The electronic device 100 may alternatively receive an input operation (for example, a single tap) of the user on the confirm option in the prompt bar 513. In response to the input operation of the user, the electronic device 100 eliminates all the security risks that exist on the electronic device 100 and the electronic device 200.

For example, as shown in FIG. 5H, the electronic device 100 receives the input operation (for example, the single tap) of the user on the confirm option in the prompt bar 513. In response to the input operation of the user, the electronic device 100 sends a control instruction to the electronic device 200 through a communication connection. The control instruction indicates the electronic device 200 to uninstall the Perfecto pinball application and the BaoFeng player application on the electronic device 200, and enable the USB debugging function on the electronic device 200. After receiving the control instruction sent by the electronic device 100, the electronic device 200 uninstalls the Perfecto pinball application and the BaoFeng player application on the electronic device 200, and enables the USB debugging function on the electronic device 200. After performing the operations, the electronic device 200 sends a performing success message to the electronic device 100. In addition, the electronic device 100 may uninstall the Quick loan application installed on the electronic device 100. After the electronic device 100 uninstalls the Quick loan application installed on the electronic device 100, and the electronic device 100 receives the performing success message sent by the electronic device 200, the electronic device 100 may display a user interface 520 shown in FIG. 5I. A security protection suggestion for the electronic device 100 and the electronic device 200 shown on the user interface 520 is “No suggestion currently”.

It should be noted that the prompt bar 513 may alternatively be displayed on the electronic device 200. This is not limited in embodiments of this application.

A prompt bar or prompt information that is described in the following embodiments of this application and that is displayed on the electronic device 100 may be displayed on the electronic device 200, or may be displayed on both the electronic device 100 and the electronic device 200. This is not limited in embodiments of this application.

Alternatively, as shown in FIG. 5G, the electronic device 100 may receive an input operation (for example, a single tap) of the user on the “one-touch eliminate” control 512. In response to the input operation of the user, the electronic device 100 sends a control instruction to the electronic device 200 through a communication connection. The control instruction indicates the electronic device 200 to uninstall the Perfecto pinball application, the BaoFeng player application on the electronic device 200, and enable a USB debugging function on the electronic device 200. After receiving the control instruction sent by the electronic device 100, the electronic device 200 uninstalls the Perfecto pinball application and the BaoFeng player application on the electronic device 200, and enables the USB debugging function on the electronic device 200. After performing the operations, the electronic device 200 sends a performing success message to the electronic device 100. In addition, the electronic device 100 may uninstall the Quick loan application installed on the electronic device 100. After the electronic device 100 uninstalls the Quick loan application installed on the electronic device 100, and the electronic device 100 receives the performing success message sent by the electronic device 200, the electronic device 100 may display a prompt bar 514 shown in FIG. 5J. The prompt bar 514 includes prompt information “The Perfecto pinball application and the BaoFeng player application on the electronic device 200 have been uninstalled, the USB debugging function on the electronic device 200 has been enabled, and the Quick loan application on the electronic device 100 has been uninstalled. Do you want to restore the previous settings?” The prompt bar 514 further includes a cancel option and a confirm option. In this way, a misoperation of the user can be prevented.

The electronic device 100 may receive an input operation (for example, a single tap) of the user on the cancel option in the prompt bar 514. In response to the input operation of the user, the electronic device 100 determines to eliminate the security risks that exist on the electronic device 100 and the electronic device 200. The electronic device 100 may alternatively receive an input operation (for example, a single tap) of the user on the confirm option in the prompt bar 514. In response to the input operation of the user, the electronic device 100 cancels elimination of all the security risks that exist on the electronic device 100 and the electronic device 200.

For example, as shown in FIG. 5J, the electronic device 100 receives the input operation (for example, the single tap) of the user on the cancel option in the prompt bar 514. In response to the input operation of the user, the electronic device 100 determines to eliminate the security risks that exist on the electronic device 100 and the electronic device 200. Then, the electronic device 200 may display a user interface 520 shown in FIG. 5I.

It should be noted that the prompt bar 514 may alternatively be displayed on the electronic device 200. This is not limited in embodiments of this application.

Optionally, if only the security protection suggestion for the electronic device 100 is displayed on the user interface 503, all the security risks that exist on the electronic device 100 may be “one-touch eliminated” with reference to the operation method shown in FIG. 5G to FIG. 5J. This reduces a user operation, and is convenient and quick.

In some embodiments, the electronic device 100 may receive an operation of the user, to display a security status of a device, a security protection suggestion for the device, a security function supported by the device, a security event generated by the device in a specific period of time, and the like.

The device may be the electronic device 100, or may be a device that establishes a communication connection to the electronic device 100. This is not limited in embodiments of this application.

FIG. 6A to FIG. 6E are diagrams of an example in which an electronic device 100 displays a security status of a device.

For example, the device may be a device that establishes a communication connection to the electronic device 100, for example, may be MatePad Pro. An electronic device corresponding to the MatePad Pro may be referred to as an electronic device 200.

As shown in FIG. 6A, the electronic device 100 receives an input operation (for example, a single tap) of a user on an icon of the electronic device 200 on a user interface 502. In response to the input operation of the user, the electronic device 100 may display a user interface 601 shown in FIG. 6B.

The user interface 601 shows protection functions supported by the electronic device 200. As shown in FIG. 6B, the protection functions supported by the electronic device 200 include but are not limited to a virus scanning and removal function, a harassment call blocking function, a WLAN security detection function, a mobile guard function, a pure mode function, a secure input method function, a verification code protection function, a payment protection function, a find device function, a lock screen password function, and the like.

The protection function supported by the electronic device 200 may be different from a protection function supported by the electronic device 100. This is not limited in embodiments of this application.

It should be noted that different devices may support different security functions. Therefore, after the electronic device 200 establishes the communication connection to the electronic device 100, the electronic device 200 needs to send the supported security function to the electronic device 100, so that the electronic device 100 may display, on the interface, the security function supported by the electronic device 200.

The electronic device 100 may receive an operation of the user on the user interface 601, to enable/disable one or more protection functions supported by the electronic device 200.

In this embodiment of this application, an example in which the “lock screen password function” on the electronic device 200 is enabled on the electronic device 100 is used for description.

As shown in FIG. 6B, the electronic device 100 receives an input operation (for example, a single tap) of the user on a “lock screen password function” option on the user interface 601. In response to the input operation of the user, the electronic device 100 may display a user interface 602 shown in FIG. 6C. A display status of the “lock screen password function” option shown on the user interface 602 is an off state. As shown in FIG. 6C, the electronic device 100 receives an input operation (for example, a single tap) of the user on the “lock screen password function” option on the user interface 602. In response to the input operation of the user, the display status of the “lock screen password function” option shown in FIG. 6D is switched from the off state to an “on” state. Specifically, after the electronic device 100 receives the input operation (for example, the single tap) of the user on the “lock screen password function” option on the user interface 602, the electronic device 100 sends an enabling instruction to the electronic device 200 through the communication connection. After receiving the enabling instruction, the electronic device 200 enables the lock screen password function on the electronic device 200 in response to the enabling instruction. After the electronic device 200 enables the lock screen password function on the electronic device 200, the electronic device 200 sends an enabling success message to the electronic device 100. After receiving the enabling success message, the electronic device 100 determines that the electronic device 100 enables the “lock screen password function”. In this case, the electronic device 100 may switch the display status of the “lock screen password function” option shown in FIG. 6D from the off state to the “on” state.

Optionally, as shown in FIG. 6E, the electronic device 100 may also switch the display status of the “lock screen password function” option on the user interface 601 from the off state to the “on” state.

FIG. 6F to FIG. 6J are diagrams of examples of a plurality of security protection suggestions provided for the electronic device 200.

As shown in FIG. 6F, the electronic device 100 may receive a slide operation (for example, an upward slide operation) performed by the user on the user interface 601. In response to the slide operation of the user, the electronic device 100 may display another security risk item on the electronic device 200, for example, a security protection suggestion.

As shown in FIG. 6G, in response to the slide operation of the user, the electronic device 100 may display the user interface 602. The user interface 602 shows some security protection suggestions. The security protection suggestions are security protection suggestions for the electronic device 200. For example, the security protection suggestions may include the following: “Perfecto pinball is detected as a virus application. It is suggested that you uninstall the application or move the application to the application security center now”. “Quick loan is detected as a scam application. Uninstallation suggested”. “Meigui pinpin is detected as a scam application. Uninstallation suggested”. “Z4root is detected as a risky application. It is suggested that you uninstall the application or move the application to the application security center now”. “It is suggested that you disable the USB debugging function, to prevent a malicious application from stealing data through the USB interface”.

Optionally, the electronic device 100 may receive a user operation to view detailed content of a security protection suggestion. For example, as shown in FIG. 6G, the electronic device 100 may receive an input operation (for example, a single tap) of the user on an option 603. In response to the input operation of the user, the electronic device 100 may display a user interface 604 shown in FIG. 6H.

As shown in FIG. 6H, the user interface 604 is a management and control interface for the “Z4root” application. The user interface 604 shows a security suggestion for the “Z4root” application. For example, the “Z4root” application is an application that is risky, and a risk level of the “Z4root” application is medium. Risk details are “The ‘Z4root’ application includes risky code. The risky code may steal the personal information of the user. Pay attention during use”. The user interface 604 further shows an option of managing and controlling the “Z4root” application and an option of uninstalling the “Z4root” application. The user may disable some permissions of the “Z4root” application on the electronic device 200 through an operation on the option of managing and controlling the “Z4root” application, for example, disabling a permission for accessing an album and disabling a permission for accessing an SMS message. The user may alternatively uninstall, through an operation on the option of uninstalling the “Z4root” application, the “Z4root” application installed on the electronic device 200.

As shown in FIG. 6H, the electronic device 100 receives an input operation (for example, a single tap) of the user on the option of uninstalling the “Z4root” application on the user interface 604. In response to the input operation of the user, the electronic device 100 may display a prompt bar 605 shown in FIG. 6I. The prompt bar 605 indicates the user whether to continue to uninstall the “Z4root” application. The electronic device 100 may receive an input operation (for example, a single tap) of the user on a cancel control in the prompt bar 605. In response to the input operation of the user, the electronic device 100 suspends uninstalling the “Z4root” application installed on the electronic device 200. The electronic device 100 may alternatively receive an input operation (for example, a single tap) of the user on an uninstall control in the prompt bar 605. In response to the input operation of the user, the electronic device 100 uninstalls the “Z4root” application installed on the electronic device 200. Specifically, after the electronic device 100 receives the input operation of the user on the uninstall control in the prompt bar 605, the electronic device 100 may send an uninstallation instruction to the electronic device 200 through the communication connection. After receiving the uninstallation instruction, the electronic device 200 uninstalls, in response to the uninstallation instruction, the “Z4root” application installed on the electronic device 200.

Optionally, in a possible implementation, after the electronic device 100 receives the input operation of the user on the option of uninstalling the “Z4root” application on the user interface 604, the electronic device 100 may first send an instruction to the second electronic device, to indicate the second electronic device to perform a corresponding operation. After the second electronic device completes performing the corresponding operation, the second electronic device sends a performing success message to the first electronic device. After receiving the performing success message sent by the second electronic device, the first electronic device may display prompt information shown in FIG. 6L, to indicate, to the user, the operation that has been performed by the second electronic device, and query the user whether to cancel the operation that has been performed by the second electronic device. The user may select again to accept the operation that has been performed by the second electronic device or cancel the operation that has been performed by the second electronic device.

Optionally, after the electronic device 200 uninstalls the “Z4root” application installed on the electronic device 200, the electronic device 200 may send an uninstallation success message to the electronic device 100. After the electronic device 100 receives the uninstallation success message sent by the electronic device 200, as shown in FIG. 6J, the electronic device 100 may display a user interface 606. A difference between the user interface 606 and the user interface 602 lies in that the security protection suggestions for the electronic device 200 that are displayed on the user interface 606 do not include “Z4root is detected as a risky application. It is suggested that you uninstall the application or move the application to the application security center now”. To be specific, it indicates that, after the “Z4root” application is deleted from the electronic device 200, a security threat caused by the “Z4root” application installed on the electronic device 200 is eliminated.

In some examples, the electronic device 100 may receive an input operation of the user on an option “View all the suggestions” on the user interface 606. In this way, the electronic device 100 can display all the security protection suggestions for the electronic device 200. Details are not described in this embodiment of this application. In the foregoing embodiments, the user interface 602 and the user interface 606 show only examples of some security protection suggestions. Compared with a security protection suggestion that is not displayed, the security protection suggestions may be understood as having a greater security protection effect on the electronic device 200.

FIG. 6G to FIG. 6J show examples in which the electronic device 100 may receive operations of the user, to sequentially (one by one) eliminate security risks that exist on the electronic device 200. In some examples, the electronic device 100 may alternatively receive an operation of the user, to “one-touch eliminate” all security risks that exist on the electronic device 200. This reduces an operation of the user.

FIG. 6K to FIG. 6N are diagrams of an example in which the electronic device 100 receives the user operation to “one-touch eliminate” all the security risks that exist on the electronic device 200.

As shown in FIG. 6K, a user interface 607 shows a “one-touch eliminate” option 608. The electronic device 100 may receive an input operation (for example, a single tap) of the user on the “one-touch eliminate” option 608. In response to the input operation of the user, the electronic device 100 may display a prompt bar 609 shown in FIG. 6L. The prompt bar 609 includes prompt information “Are you sure you want to uninstall the Perfecto pinball application, the BaoFeng player application, the Quick loan application, and the Meigui pinpin application on the electronic device 200, and enable the USB debugging function?”. The prompt bar 609 further includes a cancel option and a confirm option. In this way, a misoperation of the user can be prevented.

The electronic device 100 may receive an input operation (for example, a single tap) of the user on the cancel option in the prompt bar 609. In response to the input operation of the user, the electronic device 100 suspends eliminating the security risks that exist on the electronic device 200. The electronic device 100 may alternatively receive an input operation (for example, a single tap) of the user on the confirm option in the prompt bar 609. In response to the input operation of the user, the electronic device 100 eliminates all the security risks that exist on the electronic device 200.

For example, as shown in FIG. 6L, the electronic device 100 receives the input operation (for example, the single tap) of the user on the confirm option in the prompt bar 609. In response to the input operation of the user, the electronic device 100 sends a control instruction to the electronic device 200 through the communication connection. The control instruction indicates the electronic device 200 to uninstall the Perfecto pinball application, the BaoFeng player application, the Quick loan application, and the Meigui pinpin application on the electronic device 200, and enable the USB debugging function on the electronic device 200. After receiving the control instruction sent by the electronic device 100, the electronic device 200 uninstalls the Perfecto pinball application, the BaoFeng player application, the Quick loan application, and the Meigui pinpin application on the electronic device 200, and enables the USB debugging function on the electronic device 200. After performing the operations, the electronic device 200 sends a performing success message to the electronic device 100. After the electronic device 100 receives the performing success message, the electronic device 100 may display a user interface 610 shown in FIG. 6M. A security protection suggestion for the electronic device 200 shown on the user interface 610 is “No suggestion currently”.

Alternatively, as shown in FIG. 6K, the electronic device 100 may receive an input operation (for example, a single tap) of the user on the “one-touch eliminate” option 608. In response to the input operation of the user, the electronic device 100 sends a control instruction to the electronic device 200 through the communication connection. The control instruction indicates the electronic device 200 to uninstall the Perfecto pinball application, the BaoFeng player application, a Quick loan application, and a Meigui pinpin application on the electronic device 200, and enable a USB debugging function on the electronic device 200. After receiving the control instruction sent by the electronic device 100, the electronic device 200 uninstalls the Perfecto pinball application, the BaoFeng player application, the Quick loan application, and the Meigui pinpin application on the electronic device 200, and enables the USB debugging function on the electronic device 200. After performing the operations, the electronic device 200 sends a performing success message to the electronic device 100. After the electronic device 100 receives the performing success message, the electronic device 100 may display a prompt bar 611 shown in FIG. 6N. The prompt bar 611 includes prompt information “The Perfecto pinball application, the BaoFeng player application, the Quick loan application, and the Meigui pinpin application on the electronic device 200 have been uninstalled, and the USB debugging function has been enabled. Do you want to restore the previous settings?” The prompt bar 611 further includes a cancel option and a confirm option. In this way, a misoperation of the user can be prevented.

The electronic device 100 may receive an input operation (for example, a single tap) of the user on the cancel option in the prompt bar 611. In response to the input operation of the user, the electronic device 100 determines to eliminate the security risks that exist on the electronic device 200. The electronic device 100 may alternatively receive an input operation (for example, a single tap) of the user on the confirm option in the prompt bar 611. In response to the input operation of the user, the electronic device 100 cancels elimination of all the security risks that exist on the electronic device 200.

For example, as shown in FIG. 6N, the electronic device 100 receives the input operation (for example, the single tap) of the user on the cancel option in the prompt bar 611. In response to the input operation of the user, the electronic device 100 determines to eliminate the security risks that exist on the electronic device 200. Then, the electronic device 200 may display a user interface 610 shown in FIG. 6M.

Optionally, the electronic device 100 may also receive a user operation to view a security event generated by the electronic device 200 in a specific period of time.

FIG. 7A to FIG. 7G are diagrams of an example of viewing, on the electronic device 100, security events generated by the electronic device 200 in the specific period of time.

As shown in FIG. 7A, after the electronic device 100 displays the user interface 602, the electronic device 100 may receive a slide operation (for example, an upward slide operation) performed by the user on the user interface 602. In response to the slide operation of the user, the electronic device 100 may display a user interface 701 shown in FIG. 7B.

As shown in FIG. 7B, the user interface 701 shows security records generated by the electronic device 200 in the specific period of time (for example, seven days). The security event record includes but is not limited to a security event type, a time point at which the security event occurs, content of the security event, and the like. For example, the security event records may be as follows: 4:48 pm today, a security event type being “Harassment blocking”, and content of a security event being “123123321232 was blocked three times; 08:48 pm today, a security event type being “System root status”, and content of a security event being “The device was rooted”; 09:17 pm yesterday, a security event type being “Virus scanning and removal”, and content of a security event being “2 virus applications were found”; 08:17 pm yesterday, a security event type being “Virus scanning and removal”, and content of a security event being that “1 virus application was found”; 09:48 am yesterday, a security event type being “Lock screen password”, and content of a security event being “The lock screen password was set”. 06:18 am yesterday, a security event type being “USB debugging”, and content of a security event being “USB debugging was enabled”.

In some examples, the electronic device 100 may receive an upward/downward slide operation of the user on the user interface 701, to view more security event records. Details are not described in this embodiment of this application.

In some examples, the electronic device 100 may alternatively receive a user operation to view a detailed record of a security event record.

As shown in FIG. 7B, the electronic device 100 receives an input operation (for example, a single tap) of the user on a view control 702. In response to the input operation of the user, the electronic device 100 may display a processing interface corresponding to the security event record.

For example, the electronic device 100 may display a user interface 703 shown in FIG. 7C.

The user interface 703 shows risky applications detected on the electronic device 200 in the specific period of time (for example, seven days). Optionally, the user interface 703 may alternatively display two virus applications detected by the electronic device 100 at 9:17 pm yesterday. This is not limited in embodiments of this application.

The electronic device 100 may receive an operation of the user on the user interface 703, to uninstall one or more risky applications, so as to eliminate a security risk caused by the risky application that exists on the electronic device 200.

As shown in FIG. 7C, the electronic device 100 receives an input operation (for example, a single tap) of the user on an uninstall control 704. In response to the input operation of the user, the electronic device 100 may display a user interface 706 shown in FIG. 7D. After the electronic device 200 uninstalls the “Z4root” application, a risky application shown on the user interface 706 does not include the “Z4root” application.

Optionally, in a possible implementation, after the electronic device 100 receives the input operation of the user on the uninstall control 704, the electronic device 100 may display the prompt information shown in FIG. 6L, to indicate the user whether to perform the operation. After the user confirms performing, the electronic device 100 may send an instruction to the second electronic device, to indicate the second electronic device to perform the corresponding operation. In another possible implementation, after the electronic device 100 receives the input operation of the user on the uninstall control 704, the electronic device 100 may first send an instruction to the second electronic device, to indicate the second electronic device to perform a corresponding operation. After the second electronic device completes performing the corresponding operation, the second electronic device sends a performing success message to the first electronic device. After receiving the performing success message sent by the second electronic device, the first electronic device may display the prompt information shown in FIG. 6L, to indicate, to the user, the operation that has been performed by the second electronic device, and query the user whether to cancel the operation that has been performed by the second electronic device. The user may select again to accept the operation that has been performed by the second electronic device or cancel the operation that has been performed by the second electronic device.

For another example, as shown in FIG. 7E, the electronic device 100 may alternatively receive an input operation of the user on a “one-touch optimize” control 705, to “one-touch” uninstall malicious applications that exist on the electronic device 200. This reduces a user operation. In response to the input operation of the user, the electronic device 100 may display a user interface 707 shown in FIG. 7F. After the electronic device 200 uninstalls all the malicious applications that exist on the electronic device 200, the electronic device 100 may display prompt information, to indicate, to the user, that there is currently no malicious application.

Optionally, in a possible implementation, after the electronic device 100 receives the input operation of the user on the “one-touch optimize” control 705, the electronic device 100 may display the prompt information shown in FIG. 6L, to indicate the user whether to perform the operation. After the user confirms performing, the electronic device 100 may send an instruction to the second electronic device, to indicate the second electronic device to perform the corresponding operation. In another possible implementation, after the electronic device 100 receives the input operation of the user on the “one-touch optimize” control 705, the electronic device 100 may first send an instruction to the second electronic device, to indicate the second electronic device to perform a corresponding operation. After the second electronic device completes performing the corresponding operation, the second electronic device sends a performing success message to the first electronic device. After receiving the performing success message sent by the second electronic device, the first electronic device may display the prompt information shown in FIG. 6L, to indicate, to the user, the operation that has been performed by the second electronic device, and query the user whether to cancel the operation that has been performed by the second electronic device. The user may select again to accept the operation that has been performed by the second electronic device or cancel the operation that has been performed by the second electronic device.

Optionally, after the electronic device 200 uninstalls the malicious applications, the security events that are displayed on the electronic device 100 and that are generated by the electronic device 200 in the specific period of time do not include a security event type of virus scanning and removal. For example, the electronic device 200 may display a user interface 708 shown in FIG. 7G. The user interface 708 does not include the security event type of virus scanning and removal. Compared with the user interface 701, the user interface 708 has an additional security event, which is specifically as follows: 05:18 am yesterday, a security event type being “USB debugging”, and content of the security event being that “USB debugging was disabled”.

Optionally, after the electronic device 200 uninstalls the malicious applications, a security event that “the malicious applications are uninstalled” may be added to the security events that are displayed on the electronic device 100 and that are generated by the electronic device 200 in the specific period of time. To be specific, a processing record may be displayed in a security protection record.

After the user uninstalls the “Z4root” application on the electronic device 200, the electronic device 100 may display a user interface 709 shown in FIG. 7H. A security protection record is added to the user interface 709. Details of the security protection record are as follows: 5:18 pm today, a security event type being “Virus application uninstallation”, and content of a security event being “The “Z4root” application was uninstalled “.

Optionally, after the user enables a security function or performs the security protection suggestion, the electronic device 100 may also display an operation record of the user in the security protection record.

FIG. 8 is a schematic method flowchart of a device security processing method according to an embodiment of this application.

S802: The first electronic device receives a first operation of a user on the first user interface or the first prompt information.

The first operation may be an input operation on a “lock screen password function” option on a user interface 602.

The first operation may alternatively be an input operation on an option of uninstalling a “Z4root” application on a user interface 604.

The first operation may alternatively be an input operation on a “one-touch eliminate” option 608 on a user interface 607.

The first operation may alternatively be an input operation on an uninstall control 704 on a user interface 703.

S803: The first electronic device sends a first instruction to the second electronic device after receiving the first operation.

The first electronic device may directly send the first instruction to the second electronic device. The first electronic device may alternatively send the first instruction to the second electronic device via the server. This is not limited in embodiments of this application.

In a possible implementation, the first electronic device is further configured to: after sending the first instruction to the second electronic device, stop displaying, on the first user interface, the security risk item that exists on the second electronic device, or stop displaying the first prompt information.

In this way, after the first electronic device sends the first instruction to the second electronic device, the first electronic device can stop displaying the security risk event that exists on the second electronic device.

In a possible implementation, the second electronic device is further configured to send a second instruction to the first electronic device after eliminating the security risk item that exists on the second electronic device. The first electronic device is further configured to: after receiving the second instruction, stop displaying, on the first user interface, the security risk item that exists on the second electronic device, or stop displaying the first prompt information.

In this way, after the first electronic device determines that the second electronic device has eliminated the security risk event that exists on the second electronic device, the first electronic device can stop displaying the security risk event that exists on the second electronic device.

As shown in FIG. 6M, a user interface 610 is used as an example. A security protection suggestion for the electronic device 200 shown on the user interface 610 is “No suggestion currently”.

For another example, as shown in FIG. 6J, a security protection suggestion for the electronic device 200 displayed on a user interface 606 does not include “Z4root is detected as a risky application. It is suggested that you uninstall the application or move the application to the application security center now”.

For another example, as shown in FIG. 7F, after the electronic device 200 uninstalls all malicious applications that exist on the electronic device 200, prompt information may be displayed on a user interface 707, to indicate, to the user, that there is no malicious application currently.

For another example, as shown in FIG. 7G, the user interface 708 does not include a security event type of virus scanning and removal.

S804: After receiving the first instruction, the second electronic device eliminates the security risk item that exists on the second electronic device.

In a possible implementation, the security risk item that exists on the second electronic device includes one or more items. The first operation is an operation of eliminating a first item in the security risk item that exists on the second electronic device. The second electronic device is specifically configured to: after receiving the first instruction, eliminate the first item that exists on the second electronic device.

For example, as shown in FIG. 6G to FIG. 6I, the first electronic device may receive user operations to eliminate, one by one, security risk items that exist on the second electronic device.

In a possible implementation, the security risk item that exists on the second electronic device includes one or more items. The first operation is an operation of eliminating all the items in the security risk item that exists on the second electronic device. The second electronic device is specifically configured to: after receiving the first instruction, eliminate all the items that exist on the second electronic device.

In this way, the first electronic device can receive a user operation to “one-touch eliminate” all security risk items that exist on the second electronic device, which reduces a user operation, and is convenient and quick.

For example, as shown in FIG. 6K to FIG. 6N, the electronic device 100 may receive an input operation of the user on a “one-touch eliminate” option 608, to “one-touch eliminate” security risk items that exist on the electronic device 200.

In a possible implementation, the first electronic device is further configured to display a second user interface before displaying the first user interface, where the second user interface includes a device option of the first electronic device and a device option of the second electronic device, the device option of the first electronic device includes a security level indicator of the first electronic device, and the device option of the second electronic device includes a security level indicator of the second electronic device; and the security level indicator indicates a security status of an electronic device, and the security status includes any one of a high risk, a medium risk, a low risk, and no risk. The first electronic device is specifically configured to: receive and respond to a second operation of the user on the device option of the second electronic device on the second user interface, and display the first user interface.

The second user interface may be a user interface 502 shown in FIG. 5C.

An identifier of the first electronic device may be “Li's communication tool”, and an identifier of the second electronic device may be “MatePadPro”.

The second operation may be an input operation (for example, a single tap) on an icon of an electronic device 200 on a user interface 502.

In a possible implementation, the first electronic device is further configured to: receive and respond to a third operation of the user on the second user interface, and display a third user interface, where a security risk item that exists on the first electronic device and the security risk item that exists on the second electronic device are displayed on the third user interface. The first electronic device is further configured to receive a fourth operation of the user on the third user interface, where the fourth operation is used to eliminate the security risk item on the first electronic device and the security risk item that exists on the second electronic device. The first electronic device is further configured to: in response to the fourth operation, eliminate the security risk item that exists on the first electronic device, and send a third instruction to the second electronic device. The second electronic device is further configured to: after receiving the third instruction, eliminate the security risk item that exists on the second electronic device.

The third operation may be a slide operation on a user interface shown in FIG. 5D.

The third user interface may be a user interface 503 shown in FIG. 5G.

The fourth operation may be an input operation on a “one-touch eliminate” control 512 on the user interface 503 shown in FIG. 5G.

In a possible implementation, the first electronic device is specifically configured to: display second prompt information after receiving the first operation, where the second prompt information includes a first control, and the second prompt information indicates whether to eliminate the security risk item that exists on the second electronic device; and receive and respond to a fifth operation on the first control, and send the first instruction to the second electronic device. In this way, before the second electronic device eliminates the security risk item that exists on the second electronic device, the first electronic device can display prompt information, to avoid a misoperation of the user. Optionally, the prompt information may alternatively be displayed on the second electronic device.

The second prompt information may be a prompt bar 605 shown in FIG. 6I. The first control may be an uninstall control in the prompt bar 605. The fifth operation may be an input operation on the uninstall control in the prompt bar 605.

The second prompt information may be a prompt bar 609 shown in FIG. 6L. The first control may be a confirm option in the prompt bar 609. The fifth operation may be an input operation on the confirm option in the prompt bar 609.

In a possible implementation, the second electronic device is further configured to send the second instruction to the first electronic device after eliminating the security risk item that exists on the second electronic device. The first electronic device is further configured to display third prompt information after receiving the second instruction, where the third prompt information includes a second control, and the third prompt information indicates whether to cancel elimination of the security risk item that exists on the second electronic device. The first electronic device is specifically configured to: after receiving and responding to a sixth operation on the second control, determine to eliminate the security risk item that exists on the second electronic device. In this way, after the second electronic device eliminates the security risk item that exists on the second electronic device, the first electronic device can display prompt information, to notify the user of an operation that has been performed by the second electronic device, and can provide an option for the user to cancel the operation that has been performed by the second electronic device.

Optionally, the prompt information may alternatively be displayed on the second electronic device.

The third prompt information may be a prompt bar 611 shown in FIG. 6N. The second control may be a cancel option in the prompt bar 611. The sixth operation may be an input operation on the cancel option in the prompt bar 611.

In a possible implementation, eliminating the security risk item that exists on the second electronic device includes enabling a security function supported by the second electronic device, eliminating a security risk event generated by the second electronic device in first duration, and performing a security protection suggestion for the second electronic device.

Enabling the security function supported by the second electronic device may be enabling a “lock screen password” function on the electronic device 200 shown in FIG. 6B to FIG. 6E.

The security risk event may be the security protection record shown in the foregoing embodiments. Eliminating the security risk event generated by the second electronic device in the first duration may be uninstalling a Z4root application the electronic device 200 shown in FIG. 6G to FIG. 6I.

Performing the security protection suggestion for the second electronic device may be uninstalling the Z4root application on the electronic device 200 shown in FIG. 7B to FIG. 7D.
