With the rapid development of communication technology, the application of terminal equipment is more and more extensive, and the requirement of users on the safety performance of the terminal equipment is higher and higher.

Currently, many applications related to user privacy information are included in the terminal device, such as third party applications with payment function, mobile banking applications, and other applications. To avoid the user's private information being revealed, these applications typically provide secure input methods. In this way, when the terminal device is used for online payment or logging in an application, the user can input privacy information such as a password or a user name through a security input method provided by the application so as to prevent the privacy information of the user from being leaked.

However, since the application running in the background of the terminal device has the capability of acquiring data in the terminal device, the application running in the background of the terminal device can acquire the privacy information input by the user even if the user inputs the privacy information (such as a password) through a secure input method during the online payment or login process of the terminal device. As such, private information of the user may be leaked, resulting in poor security performance of the terminal device.

In fig. 1, the architecture of the android operating system includes 4 layers, which are respectively: an application layer, an application framework layer, a system runtime layer, and a kernel layer (specifically, a Linux kernel layer).

The application program layer comprises various application programs (including system application programs and third-party application programs) in an android operating system.

The application framework layer is a framework of the application, and a developer can develop some applications based on the application framework layer under the condition of complying with the development principle of the framework of the application. The application framework layer includes a window manager service layer (window manager service), an interface layer (surface), an interface session layer (surface session), and an interface object layer (surface component).

The window management service layer is used for processing operations such as starting, adding and deleting of an interface window of the terminal equipment; the interface layer is used for displaying a window of an interface in the terminal equipment; the interface session layer plays a role of identification in the interface session; the interface object layer is used for indicating the client role in the interface session.

The library mainly provides various resources required by the android operating system. The android operating system running environment is used for providing a software environment for the android operating system. The system runtime layer also includes a surface flicker (sfl) layer and a display layer (display hard ware).

The interface combination layer is used for combining the content in the interface layer to form a complete interface; the display layer is used for indicating a display screen of the terminal equipment.

The kernel layer is an operating system layer of an android operating system and belongs to the bottommost layer of an android operating system software layer. The kernel layer provides kernel system services and hardware-related drivers for the android operating system based on the Linux kernel. The inner core layer includes a frame buffer layer (frame buffer).

It should be noted that fig. 1 is a schematic diagram of a display architecture based on an operating system, for example, a terminal device includes an operating system. In a specific implementation, the terminal device may further include a plurality of operating systems, that is, the terminal device may include a display architecture of the plurality of operating systems, where each display architecture is similar to the display architecture described in fig. 1, and in order to avoid repetition, details are not repeated here.

Taking an android operating system as an example, in the embodiment of the present invention, a developer may develop a software program for implementing the control method provided in the embodiment of the present invention based on the system architecture of the android operating system shown in fig. 1, so that the control method may operate based on the android operating system shown in fig. 1. Namely, the processor or the terminal device can implement the control method provided by the embodiment of the invention by running the software program in the android operating system.

The terminal equipment in the embodiment of the invention can be a mobile terminal or a non-mobile terminal. For example, the mobile terminal may be a mobile phone, a tablet computer, a notebook computer, a palm top computer, a vehicle-mounted terminal, a wearable device, an ultra-mobile personal computer (UMPC), a netbook or a Personal Digital Assistant (PDA), and the like, and the non-mobile terminal may be a Personal Computer (PC), a Television (TV), a teller machine or a self-service machine, and the like, and the embodiment of the present invention is not particularly limited.

The execution main body of the control method provided by the embodiment of the present invention may be the terminal device, or may also be a functional module and/or a functional entity capable of implementing the control method in the terminal device, which may be specifically determined according to actual use requirements, and the embodiment of the present invention is not limited. The following takes a terminal device as an example to exemplarily explain a control method provided by the embodiment of the present invention.

In the embodiment of the present invention, when the terminal device runs a certain application (for example, the second application in the embodiment of the present invention) on a foreground (hereinafter, referred to as the foreground) of the terminal device, if another application (for example, the first application in the embodiment of the present invention) runs on a background (hereinafter, referred to as the background) of the terminal device, the applications may acquire data of the application running on the foreground, and thus privacy information of a user may be leaked. Therefore, when the terminal device detects that the user triggers the terminal device to run a certain application in the foreground of the terminal device, or the terminal device detects that the user triggers the terminal device to execute certain specific operations (such as inputting a password and account information) through the application, the terminal device can close the application running in the background, or set the use state of the application running in the background to a forbidden state, so that the applications cannot acquire data of the application running in the foreground, the privacy information of the user can be protected, and the safety performance of the terminal device can be improved.

The following describes an exemplary control method provided by an embodiment of the present invention with reference to the drawings.

As shown in fig. 2, an embodiment of the present invention provides a control method, which may include S201 and S202 described below.

S201, the terminal device detects the input of the user.

S202, under the condition that the input of the user is detected to be the first input, the terminal equipment closes the first application running in the background of the terminal equipment or sets the use state of the first application to be the forbidden state.

Wherein, the first input may be any one of the following items: and the user triggers the terminal equipment to run the input of the second application in the foreground of the terminal equipment, and the user triggers the terminal equipment to execute the input of the preset operation through the second application.

In the embodiment of the present invention, the terminal device may detect an input of a user, and when the terminal device detects the first input, the terminal device may perform a specific operation on the first application.

Specifically, in the embodiment of the present invention, when the terminal device detects that the user triggers the terminal device to run a certain application (i.e., the second application) in the foreground, the terminal device may close the first application; or, when the terminal device detects that the user triggers the terminal device to run the second application in the foreground, the terminal device may set the use state of the first application to the disabled state. When the terminal device detects that the user triggers the terminal device to execute the preset operation through the second application, the terminal device can close the first application; or, when the terminal device detects that the user triggers the terminal device to execute the preset operation through the second application, the terminal device may set the use state of the first application to a disabled state.

It can be understood that the terminal device running a certain application in the foreground may be used to indicate: the terminal device displays the interface of the application in the display screen of the terminal device, and the user can trigger the terminal device to execute the operation corresponding to the input of the user through the application through the input in the interface of the application. The above terminal device runs a certain application in the background to indicate: the process of the application runs in the operating system of the terminal device, but the interface of the application is not displayed in the display screen of the terminal device.

It should be noted that, in the embodiment of the present invention, setting, by the terminal device, the use state of the first application to the disabled state may be understood as: the terminal device closes the application process of the first application, and after the terminal device sets the use state of the first application to the disabled state, the terminal device cannot perform any operation on the first application, and cancels display of an identifier (such as an icon of the first application) indicating the first application in an interface of the terminal device, which is equivalent to that the first application is not installed in the terminal device. The closing of the first application by the terminal device may be understood as: and the terminal equipment closes the application process of the first application.

Optionally, in this embodiment of the present invention, the terminal device may periodically detect an input of the user.

Optionally, in the embodiment of the present invention, a period for detecting the input of the user by the terminal device may be a preset numerical value in the terminal device, and the period for detecting the input of the user by the terminal device may be preset in the terminal device by a manufacturer of the terminal device according to the performance of the terminal device. The method can be determined according to actual use requirements, and the embodiment of the invention is not limited.

Illustratively, the period in which the terminal device detects the user's input may be any possible duration, such as 1 second, 2 seconds, or 3 seconds.

Optionally, in this embodiment of the present invention, the first input may include two cases, which are a case one and a case two respectively. The following specifically illustrates these two cases (i.e., case one and case two) of the first input.

The first condition is as follows: the first input is input for triggering the terminal equipment to run the second application in the foreground of the terminal equipment by a user.

Optionally, the first case may include at least one of the following: the user triggers the terminal device to run the second application in the foreground through inputting the icon of the second application (namely, the user triggers the terminal device to display the interface of the second application in the display screen of the terminal device through inputting the icon of the second application); the terminal equipment runs the second application in the background, and the user triggers the terminal equipment to switch the second application from the background to the foreground.

It will be appreciated that in actual implementation, the above case may also include any other possible implementation. The method can be determined according to actual use requirements, and the embodiment of the invention is not limited.

Case two: the first input is input for triggering the terminal equipment to execute preset operation through the second application by the user.

It should be noted that, in case two, when the user triggers the terminal device to execute the preset operation through the second application, the application run in the foreground by the terminal device is the second application.

Optionally, in this embodiment of the present invention, the preset operation may be an operation preset in the terminal device. The preset operation can be preset in the terminal equipment according to the use requirements of possible users for a terminal equipment manufacturer, and can also provide a setting interface for the terminal equipment manufacturer, and the user is preset in the terminal equipment according to the use requirements of the user. The method and the device can be used according to actual use requirements, and the embodiment of the invention is not limited.

Optionally, in an embodiment of the present invention, the preset operation may include: logging in an account, entering a username, entering a password, sending a message, and planning a route, among other operations, may involve user privacy information. The method can be determined according to actual use requirements, and the embodiment of the invention is not limited.

Optionally, in the embodiment of the present invention, the first application may be any application in the terminal device, and may also be a target application in the terminal device. The method can be determined according to actual use requirements, and the embodiment of the invention is not limited.

Optionally, in this embodiment of the present invention, when the first application is a target application in the terminal device, the target application may include an application other than a system application in the terminal device, for example, a third-party application.

It should be noted that, when the first application is any application in the terminal device, if the terminal device detects the first input, the terminal device may close all applications running in the background; or, the use state of all the applications running in the background is set to the disabled state. When the first application is a target application in the terminal device, if the terminal device detects the first input, the terminal device may close the target application running in the background; or setting the use state of the target application running in the background to be a forbidden state.

It is to be understood that, when non-target applications (e.g., system applications of the terminal device, etc.) are included in the applications running in the background, if the terminal device detects the first input, the terminal device may not perform any processing on the non-target applications running in the background, that is, the non-target applications still run in the background.

Optionally, in this embodiment of the present invention, the second application may be any application in the terminal device, and may also be an application of the first target type. The method can be determined according to actual use requirements, and is not limited in the embodiment of the invention.

Optionally, in this embodiment of the present invention, the first target type may include any application type that may relate to user privacy information, such as a payment type, a financial type, a communication type, and a shopping type. The method can be determined according to actual use requirements, and is not limited in the embodiment of the invention.

The following describes the above S201 and S202 by way of example.

For example, it is assumed that the first application is a third-party application in the terminal device, the second application is a payment-type application in the terminal device, the first input is an input that the user triggers the terminal device to run the second application in a foreground, and when the terminal device detects the first input, the terminal device sets the use state of the first application to a disabled state. Then, when three applications run in the background of the terminal device, the three applications are respectively: the application 1 is a system application in the terminal equipment, and the application 2 and the application 3 are third-party applications in the terminal equipment. If the terminal device detects that the user triggers the terminal device to run the application "pay 1" (i.e. the second application) in the foreground, the terminal device may set the use states of the application 2 and the application 3 (i.e. the application 2 and the application 3 are the first application) to the disabled state, so that the application 2 and the application 3 cannot acquire the privacy information of the user from the application "pay 1" to protect the privacy information of the user. Where "application 1" continues to run in the background.

Optionally, in this embodiment of the present invention, when the terminal device detects that the input of the user is the first input, the terminal device may determine whether the first application is running in the background, and if the first application is running in the background, the terminal device may close the first application or set the use state of the first application to the disabled state, and run the second application in the foreground; if the background does not run the first application, the terminal device may be running the second application.

For example, in conjunction with fig. 2, as shown in fig. 3, the above S202 may be implemented by S202a-S202c, or S202a and S202c, which are described below.

S202a, in the case that the input of the user is detected to be the first input, the terminal device determines whether the first application is running in the background of the terminal device.

S202b, the terminal device closes the first application running in the background of the terminal device or sets the use state of the first application to be disabled.

S202c, the terminal device runs the second application.

It should be noted that, in the embodiment of the present invention, the terminal device running the second application may be used to instruct the terminal device to run the second application in the foreground.

In the embodiment of the present invention, when the terminal device detects that the input of the user is the first input, the terminal device may determine whether the first application is running in the background, and if the first application is running in the background, the terminal device may close the first application or set the use state of the first application to a disabled state, and run the second application in the foreground; if the background does not run the first application, the terminal device may run the second application in the foreground. Therefore, in the control method provided by the embodiment of the invention, when the terminal device runs the second application in the background, the first application is not run in the background, so that the first application cannot acquire the privacy information of the user from the second application, the privacy information of the user can be protected, and the security performance of the terminal device can be improved.

It should be noted that, in the case where the first application is running in the background, the execution sequence between S202b and S202c may not be limited in the embodiment of the present invention. That is, in the embodiment of the present invention, S202b may be executed first, and then S202c may be executed; s202c may be executed first, and then S202b may be executed. In fig. 3, the first step of performing S202b and the second step of performing S202c are exemplified as an example.

The embodiment of the present invention provides a control method, where an application (i.e., a first application) running in a background of a terminal device may obtain data of an application (i.e., a second application) running in a foreground of the terminal device, for example, obtain a user name, user information, a password input by a user, and the like in the second application, so that when the terminal device detects that the user triggers the terminal device to run the second application in the foreground of the terminal device, or when the terminal device detects that the user triggers the terminal device to execute some specific operations (for example, inputting a password and the like) through the second application, the terminal device may close the first application running in the background of the terminal device, or set a use state of the first application running in the background of the terminal device to a disable state. Therefore, the first application can not acquire the data of the second application running in the foreground of the terminal device, namely the first application can not acquire the privacy information of the user from the second application, so that the privacy information of the user can be protected, and the safety performance of the terminal device can be improved.

Optionally, in this embodiment of the present invention, after the terminal device runs the second application, the terminal device may determine whether the second application includes an input method (that is, the second application has an own input method, for example, the first input method in this embodiment of the present invention). In the case that the input method is included in the second application, the terminal device may display a virtual keyboard of the input method in an interface of the second application; in the case where the input method is not included in the second application, the terminal device may display a virtual keyboard of the input method of the system of the terminal device in the interface of the second application. Therefore, the user can input information through a safe input method to ensure the safety of the information input by the user.

For example, referring to fig. 3, as shown in fig. 4, after S202c, the control method provided in the embodiment of the present invention may further include S203 and S204, or S203 and S205, which are described below.

S203, the terminal device determines whether the second application comprises the first input method.

And S204, the terminal equipment displays the first virtual keyboard in the interface of the second application.

The first virtual keyboard may be a virtual keyboard of the first input method.

And S205, the terminal device displays a second virtual keyboard in the interface of the second application.

The second virtual keyboard may be a virtual keyboard of a second input method, and the second input method may be a system input method of the terminal device.

In this embodiment of the present invention, after the terminal device runs the second application, the terminal device may determine whether the second application includes an input method (i.e., the first input method). And after determining whether the input method is included in the second application, if the first input method is included in the second application, the terminal device may display a virtual keyboard of the first input method (i.e., the first virtual keyboard) in an interface of the second application, so that a user may input information in the second application through the first virtual keyboard. If the first input method is not included in the second application, the terminal device may display a virtual keyboard of the system input method of the terminal device (i.e., the second virtual keyboard) in an interface of the second application, so that the user may input information in the second application through the second virtual keyboard. In this way, the user can input information in the second application through a safe input method, so that the safety of the information input by the user is ensured.

It is to be understood that the first input method may be an input method carried by the second application, for example, a security input method of the second application.

Optionally, in this embodiment of the present invention, after the terminal device determines whether the second application includes the first input method, the user may trigger the terminal device to display the first virtual keyboard or the second virtual keyboard in the interface of the second application through an input (for example, a third input in this embodiment of the present invention).

Specifically, in the embodiment of the present invention, after the terminal device determines whether the second application includes the first input method, in a case that the second application includes the first input method, a user may trigger the terminal device to display the first virtual keyboard in an interface of the second application through a third input; and under the condition that the second application does not comprise the first input method, the user can trigger the terminal equipment to display the second virtual keyboard in the interface of the second application through a third input.

In this embodiment of the present invention, the third input may be an input that a user triggers the terminal device to display a virtual keyboard in the interface of the second application.

Optionally, in this embodiment of the present invention, the third input may be input by a user in an information input area of the interface of the second application. Specifically, the third input may be any possible input such as a single-click input, a double-click input, or a long-press input of the user in the information input area. The method can be determined according to actual use requirements, and the embodiment of the invention is not limited.

In the embodiment of the present invention, the long press input may be an input that a user presses in the information input area for a time period longer than or equal to a preset time period.

Optionally, in the embodiment of the present invention, the preset time duration may be a preset numerical value in the terminal device. The preset duration may be preset in the terminal device by a manufacturer of the terminal device. The method can be determined according to actual use requirements, and the embodiment of the invention is not limited.

In the embodiment of the present invention, since the first input method is an input method in the second application, the terminal device may determine that the first input method is a safe input method, and if the terminal device displays the first virtual keyboard in the interface of the second application, the user may input information through the safe input method. Correspondingly, since the second input method is a system input method, the terminal device may also determine that the second input method is a secure input method, and if the terminal device displays the second virtual keyboard in the interface of the second application, the user may input information through the secure input method. Therefore, no matter the user inputs information by using the virtual keyboard of the first input method or inputs information by using the virtual keyboard of the second input method, the user can input information by using a safe input method, so that the user can be prevented from inputting information by using a non-system input method (such as a third-party input method), and the safety of the information input by the user can be further ensured.

Optionally, in this embodiment of the present invention, the terminal device may further detect an application running in the foreground of the terminal device, and when the terminal device detects that a certain specific application (for example, a third application in this embodiment of the present invention) runs in the foreground of the terminal device, the terminal device may prohibit applications (for example, a fourth application in this embodiment of the present invention) other than the application running in the foreground in the terminal device from using some functions (for example, target functions in this embodiment of the present invention) of the terminal device, so as to prevent the applications from obtaining information of the application running in the foreground through the functions, and thus, it may be ensured that privacy information of a user is not leaked.

For example, referring to fig. 2, as shown in fig. 5, after S202, the control method provided in the embodiment of the present invention may further include S206 and S207 described below.

And S206, the terminal equipment detects the application running in the foreground of the terminal equipment.

And S207, under the condition that the application operated in the foreground of the terminal device is detected to be the third application, forbidding the fourth application to use the target function of the terminal device.

The fourth application may be an application other than the third application in an application of the terminal device, and the target function may include at least one of: a recording function, a screen capture function, and a read/write function.

In the embodiment of the invention, the terminal device can detect the application running on the foreground of the terminal device, and when the terminal device detects that the application running on the foreground of the terminal device is the third application, the terminal device can forbid the fourth application from using the target function of the terminal device, so that the fourth application can be prevented from acquiring the data in the third application through the target application to acquire the privacy information of the user, and the privacy information of the user can be ensured not to be leaked.

It should be noted that, in the embodiment of the present invention, the read/write function may include a read function and a write function. The reading function comprises the functions of reading short messages, accessing a gallery and the like, and the functions can read data in the terminal equipment; the writing function may include a function of editing content in an application in the terminal device, such as writing a mail and editing information.

Optionally, in this embodiment of the present invention, the third application may be any application in the terminal device, and may also be an application of a second target type. The method can be determined according to actual use requirements, and is not limited in the embodiment of the invention.

Optionally, in this embodiment of the present invention, the second target type may include any application type that may relate to user privacy information, such as a payment type, a financial type, a communication type, and a shopping type. The method can be determined according to actual use requirements, and is not limited in the embodiment of the invention.

Optionally, in this embodiment of the present invention, the fourth application may be all applications in the terminal device except the third application, or may be an application that may have a security risk in the terminal device, for example, a third-party application in the terminal device. The method can be determined according to actual use requirements, and is not limited in the embodiment of the invention.

It should be noted that the execution sequence between S201-S202 and S206-S207 may not be limited in the embodiment of the present invention. That is, in the embodiment of the present invention, S201 to S202 may be executed first, and then S206 to S207 may be executed; it is also possible to perform S206-S207 first and then S201-S202. In fig. 5, the steps S201 to S202 are executed first, and then the steps S206 to S207 are executed as an exemplary illustration.

In the embodiment of the present invention, since functions (i.e., the target function) in the terminal device, such as a recording function, a screen capture function, and a read/write function, have the capability of acquiring data in the terminal device, the fourth application may acquire data of the terminal device using the third application by using these functions, that is, the fourth application may acquire the privacy information of the user. Therefore, under the condition that the terminal equipment forbids the fourth application to use the target function, the fourth application can not acquire the data of the terminal equipment using the third application, so that the safety of the privacy information of the user can be ensured, and the safety performance of the terminal equipment can be improved.

Optionally, in this embodiment of the present invention, after the terminal device sets the use state of the first application to the disabled state, if the terminal device determines that the terminal device exits from the second application, the terminal device may set the state of the first application to an enabled state, so that the user may normally use the first application.

For example, referring to fig. 2, as shown in fig. 6, after S202, the control method provided in the embodiment of the present invention may further include S208 described below.

And S208, after the terminal equipment exits from the second application, the terminal equipment sets the use state of the first application to be an enabling state.

In the embodiment of the present invention, after the terminal device sets the use state of the first application to the disabled state, if the terminal device exits from the second application, the terminal device may set the use state of the first application to the enabled state, so that the user may normally use the first application.

It should be noted that, in the embodiment of the present invention, the terminal device quitting the second application is used to instruct the terminal device to end running the second application (that is, the terminal device background and the terminal device foreground do not run the second application).

In the embodiment of the present invention, after the terminal device exits from the second application, even if the terminal device runs the first application in the background, the first application cannot acquire the information of the user in the second application, so that the terminal device may set the use state of the first application to the enabled state, so that the user may normally use the first application.

Optionally, in this embodiment of the present invention, after the terminal device sets the usage state of the first application to the disabled state, if the terminal device determines that the terminal device exits the second application, after the terminal device exits the second application, the terminal device may delete user data (for example, target data in this embodiment of the present invention) of the second application stored in the terminal device, so as to prevent leakage of the user data; alternatively, the terminal device may encrypt the user data of the second application stored in the terminal device so that other applications cannot access the user data of the second application, and thus the user data may be prevented from being leaked. Therefore, the safety performance of the terminal equipment can be improved.

For example, referring to fig. 2, as shown in fig. 7, after S202, the control method provided in the embodiment of the present invention may further include S209 described below.

And S209, after the terminal equipment exits the second application, the terminal equipment deletes the target data or encrypts the target data.

The target data may be user data of the second application stored in the terminal device.

In the embodiment of the present invention, after the terminal device exits from the second application, the terminal device may delete the target data; alternatively, the target data is encrypted to ensure that the target data is not compromised.

Optionally, in this embodiment of the present invention, before the terminal device encrypts the target data, the terminal device may display a prompt message to prompt the user to set an encryption password for the target data, and then the terminal device may encrypt the target data according to the encryption password, so that other applications cannot access the target data.

In the embodiment of the present invention, the encrypting the target data by the terminal device may be understood as: the target data is not visible to other applications, thereby making it impossible for these applications to acquire/access the target data.

In the embodiment of the present invention, since the terminal device deletes the target data to prevent other applications from acquiring the target data, or the terminal device encrypts the target data to prevent other applications from acquiring the target data, after the terminal device exits the second application, the terminal device uses any one of the two manners (deleting the target data and encrypting the target data) to prevent the user data of the second application used by the user from being leaked, so that the privacy information of the user can be protected, and the security performance of the terminal device can be further improved.

In the embodiment of the present invention, two operating systems are taken as an example below, and an exemplary description is given of a case where the terminal device in the embodiment of the present invention includes a plurality of operating systems.

Optionally, in the embodiment of the present invention, when the terminal device includes two operating systems (e.g., the first operating system and the second operating system in the embodiment of the present invention), the control method provided in the embodiment of the present invention may be applied to each of the two operating systems, or may be applied to one of the two operating systems (e.g., the second operating system in the embodiment of the present invention).

Optionally, in this embodiment of the present invention, when the control method provided in this embodiment of the present invention is applied to one operating system (hereinafter, referred to as a second operating system) of the two operating systems, if the operating system run by the terminal device is another operating system (hereinafter, referred to as a first operating system), the user may trigger the terminal device to run the second operating system through an input (hereinafter, referred to as a second input) to a certain object (for example, a target object in this embodiment of the present invention) in a user interface of the first operating system, so that the terminal device may execute the steps of the control method in the foregoing embodiment in the second operating system.

Optionally, the terminal device in the embodiment of the present invention may be a single-screen terminal device, and may also be a multi-screen terminal device. The method can be determined according to actual use requirements, and the embodiment of the invention is not limited.

In the embodiment of the present invention, when the number of screens of the terminal device is different, the terminal device may respond to the second input in different forms. Specifically, when the number of screens of the terminal device is one (that is, the terminal device is a single-screen terminal device), the form of the terminal device responding to the second input may be a form one; when the number of the screens of the terminal device is greater than one (that is, the terminal device is a multi-screen terminal device), the form of the terminal device responding to the second input may be a form two. The following exemplary description of specific terminal devices responding to these two forms of the second input (i.e., form one and form two) is provided.

The first form: in a case that the operating system run by the terminal device is the first operating system, the user may trigger the terminal device to switch the operating system run by the terminal device from the first operating system to the second operating system through a second input to a certain object (for example, a target object in the embodiment of the present invention) in the user interface of the first operating system, so that the terminal device may execute the steps of the control method in the foregoing embodiment in the second operating system.

For example, referring to fig. 2, as shown in fig. 8, before S201, the control method provided in the embodiment of the present invention may further include S210 and S211 described below. Specifically, S201 may be implemented by S201a described below.

And S210, the terminal equipment receives a second input of the target object by the user.

And S211, the terminal equipment responds to the second input and switches the operating system of the terminal equipment from the first operating system to the second operating system.

S201a, the terminal device detects the user input in the second operating system.

The target object may be a target identifier or a target key, and the second input may be an input received by the terminal device in the first operating system.

In this embodiment of the present invention, when the operating system run by the terminal device is the first operating system, a user may trigger the terminal device to switch the operating system of the terminal device from the first operating system to the second operating system through an input to the target object, so that the terminal device detects an input of the user in the second operating system, and then the terminal device may execute the control method provided in this embodiment of the present invention in the second operating system according to the input of the user detected by the terminal device in the second operating system.

Optionally, in this embodiment of the present invention, if the target object is the target identifier, the target identifier may be an identifier used for indicating a second operating system in the first operating system.

Optionally, in this embodiment of the present invention, the target identifier may be an icon, or an interface and the like, which may be used to indicate the identifier of the second operating system. The method can be determined according to actual use requirements, and the embodiment of the invention is not limited.

Optionally, in this embodiment of the present invention, when the target object is the target identifier, the second input may be any possible input, such as a single-click input, a double-click input, or a re-press input, of the user on the target identifier. The method can be determined according to actual use requirements, and the embodiment of the invention is not limited.

In an embodiment of the present invention, the press-again input may be an input that a user presses on the target identifier with a pressure greater than or equal to a preset pressure value.

Optionally, in this embodiment of the present invention, the preset pressure value may be a preset value in the terminal device. The preset pressure value may be preset in the terminal device by the manufacturer of the terminal device. The method can be determined according to actual use requirements, and the embodiment of the invention is not limited.

Optionally, in the embodiment of the present invention, if the target object is the target key, the target key may be one key or a combination key formed by combining a plurality of keys. The method can be determined according to actual use requirements, and the embodiment of the invention is not limited.

For example, when the target key is a key, the target key may be any possible key such as a power key, an Artificial Intelligence (AI) key, or a volume key. When the target key is a combination key of a plurality of key combinations, the target key may be a combination of a power key and a volume key, or any possible key combination such as a combination of a power key and an AI key.

Optionally, in this embodiment of the present invention, when the target object is the target key, the second input may be any possible input, such as a long-press input or a short-press input of the target key by the user. The method can be determined according to actual use requirements, and the embodiment of the invention is not limited.

Optionally, in this embodiment of the present invention, the first operating system and the second operating system may be two different operating systems in the terminal device.

In an embodiment of the present invention, the first operating system and the second operating system may be developed by a terminal device manufacturer based on a source code of the operating system.

Optionally, in the embodiment of the present invention, the first operating system may be an operating system with a relatively high development degree of a terminal device manufacturer, and the second operating system may be an operating system with a relatively low development degree of the terminal device manufacturer.

It should be noted that, in the embodiment of the present invention, the source code similarity between the operating system with a relatively low development degree of the terminal device manufacturer and the operating system is relatively high, and the source code similarity between the operating system with a relatively high development degree of the terminal device manufacturer and the operating system is relatively low.

Of course, it is understood that the second operating system may also be an operating system corresponding to a platform provided by an operating system vendor.

Optionally, in the embodiment of the present invention, after the operating system manufacturer modifies the operating system provided by the operating system manufacturer, the operating system manufacturer may release the modified system patch to the terminal device manufacturer, so that the operating system used by the terminal device manufacturer is more complete and secure. After the operating system manufacturer releases the modified system patch to the terminal device manufacturer, the terminal device manufacturer may update the operating systems (e.g., the first operating system and the second operating system) on the terminal device in real time using the system patch. Therefore, after the terminal device updates the second operating system on the terminal device in real time, the terminal device can execute the control method provided by the embodiment of the invention in the more complete and safe second operating system, that is, the software environment for the terminal device to execute the control method is more complete and safe.

It should be noted that, for the above "form one," after the terminal device switches the operating system of the terminal device from the first operating system to the second operating system, the terminal device may execute the steps of the control method in the foregoing embodiment in the second operating system, and details are not described here to avoid repetition.

The second form: in a case that the terminal device runs the first operating system and does not run the second operating system, the user may trigger the terminal device to run the second operating system through a second input to a certain object (for example, a target object in the embodiment of the present invention) in the user interface of the first operating system (for example, the terminal device displays the user interface of the second operating system on the second screen of the terminal device), and then the terminal device may execute the steps of the control method in the above embodiment in the second operating system.

It should be noted that, the above "form two" is exemplarily explained by taking the number of screens of the terminal device as two (that is, the terminal device is a dual-screen terminal device) as an example, and the implementation manner for other cases where the number of screens of the terminal device is greater than one is similar to the implementation manner where the number of screens of the terminal device is two, and is not described again here.

The target object may be a target identifier or a target key, the second input may be an input received by the terminal device in a first operating system, the first operating system corresponds to a first screen of the terminal device, and the second operating system corresponds to a second screen of the terminal device.

In the embodiment of the present invention, when the terminal device runs the first operating system and does not run the second operating system, the user may trigger the terminal device to run the second operating system through an input to the target object, so that the terminal device detects an input of the user in the second operating system, and then the terminal device may execute the control method provided in the embodiment of the present invention in the second operating system according to the input of the user detected by the terminal device in the second operating system.

In this embodiment of the present invention, the correspondence between the first operating system and the first screen of the terminal device may be: the terminal equipment displays a user interface of the first operating system in a first screen of the terminal equipment; the correspondence between the second operating system and the second screen of the terminal device may be: and the terminal equipment displays the user interface of the second operating system in a second screen of the terminal equipment.

In other words, the application in the first screen of the terminal device (i.e., the application indicated by the application icon displayed in the first screen) may be run in the first operating system, and user data generated by the application in the first screen may be saved in the first operating system. Accordingly, the application in the second screen of the terminal device (i.e., the application indicated by the application icon displayed in the second screen) may be run in the second operating system, and the user data generated by the application in the second screen may be saved in the second operating system.

In the embodiment of the present invention, after the terminal device runs the second operating system, the terminal device may continue to run the first operating system. That is, the terminal device may simultaneously run the first operating system and the second operating system.

Optionally, as for the above "form two", the terminal device in the embodiment of the present invention may include a plurality of processors, or the processor of the terminal device is a multi-core processor. The method can be determined according to actual use requirements, and the embodiment of the invention is not limited.

Specifically, when the terminal device includes a plurality of processors, one processor in the terminal device may correspond to one operating system. Taking the example that the terminal device includes two processors, processor 1 and processor 2 respectively. The processor 1 may correspond to the first operating system, and the processor 2 may correspond to the second operating system.

Of course, after the terminal device runs the second operating system, the terminal device may also stop running the first operating system. The method can be determined according to actual use requirements, and the embodiment of the invention is not limited.
