The role of data being stolen. Let's take a detailed explanation.

Please refer to FIG. 1. FIG. 1 is a schematic flowchart diagram of a background process management method according to an embodiment of the present invention. The background process management method shown in FIG. 1 may include the following steps:

The terminal device selects a target background process from the currently running background process; wherein the target background process is a non-essential or malicious background process.

In the embodiment of the present invention, the terminal device may be a smart phone, a smart watch, a palmtop computer, a tablet computer, a personal digital assistant (PDA), a point of sales (POS), etc. Do not repeat.

In the embodiment of the present invention, in order to save memory, power, and data traffic of the terminal device, a background process that is currently running on the terminal device may be filtered out of unnecessary or malicious background processes, and the background processes are frozen to be closed and cannot be started. . The above malicious background process refers to a background process that steals user personal information and private data by monitoring screen actions, keyboard input and the like. The above-mentioned non-essential background process refers to a background process corresponding to the software or function that the user uses very low frequency or even never used, such as the background process of the remote control function, the background process of the system with the notepad, and the background of the system search function. Process, etc. For example, the background process of the system search function, the background process generally runs the registration event by default, but the user generally uses the system search function less, so the background process can be considered to be frozen.

However, due to differences in user habits, some features may be commonly used at very low frequencies, and users often use them for personal reasons. In this case, the user can manually set a background process that can freeze the list of background processes, thereby avoiding freezing the functions that they often use.

In the embodiment of the present invention, the terminal device may select some special moments to filter the currently running background process. As an optional implementation manner, the terminal device determines whether the current state is changed from the power-off state to the power-on state. If the current state is changed from the power-off state to the power-on state, the target background process is selected from the currently running background process.

As an optional implementation manner, the terminal device receives an operation instruction that the user searches for a freezeable background process, and selects a target background process from the currently running background process according to the operation instruction.

As an optional implementation manner, the terminal device monitors whether a new background process is started. If a new background process is started, the target background process is selected from the currently running background process.

In the embodiment of the present invention, the user may preset a list of freezeable background processes according to the usage habits of the individual, and record the background process corresponding to the application and function whose usage frequency is extremely low or even never used, into the list of freezeable background processes. As an optional implementation manner, the terminal device monitors whether a new background process is started. If a new background process is started, the currently running background process is in the background process according to the preset freezeable background process list preset by the user. The background process in the list is selected as the target background process.

In the embodiment of the present invention, the terminal device may also select, as the target background process, the background process in which the security software in the currently running background process is evaluated as a non-essential or malicious process according to the evaluation of the background process by the security software in the terminal device.

102. The terminal device stops the foregoing target background process from running.

In the embodiment of the present invention, after the terminal device filters out the target background process (that is, the background process to be frozen), the background process stops running, and the data and the log are saved, so as to prevent the background process from being forcibly closed to cause data loss.

103. The terminal device sends a freeze instruction to the target background process, so that the target background process is closed and cannot be started.

In the embodiment of the present invention, after the terminal device stops the target background process to be frozen, the data and the log are saved, and then the freeze command is sent to the target background process, and the target background process performs the shutdown operation according to the freeze instruction, and the corresponding parameter is modified. Cannot start until the target background process is thawed and can start normally.

In the method shown in FIG. 1, the terminal device may filter the currently running background process when the device is just started or when a new background process occurs, wherein the terminal device may be based on a freezeable background process list or a security software pair preset by the user. The evaluation of the background process filters out the background processes that need to be frozen in the currently running background process. After selecting the background process to be frozen, the terminal device stops the background process, sends a freeze instruction to the background process, and causes it to be closed and cannot be started. It can be seen that the implementation of the method can make the unnecessary and malicious background processes freeze and cannot be started, thereby saving memory, saving power and data traffic, and preventing the user's personal information and private data from being stolen.

203. The terminal device determines, according to the priority of the target background process, whether the target background process is allowed to be frozen.

In the embodiment of the present invention, the background processes running in the system have corresponding priorities, and the priorities determine when the background processes run and how much CPU time is occupied. The basic functions necessary in the system generally have high priority, such as task manager, key input monitoring, etc., and some applications set a higher priority for their own background processes in order to ensure their own running quality. If the background process with high priority is frozen, it may affect the normal use of the terminal device. Therefore, the terminal device determines the priority of the target background process. If the priority is high, it determines that the background process is not allowed to be frozen. If the priority is normal, it is determined that the background process is allowed to be frozen.

204. If the target background process is allowed to be frozen, the terminal device sends a freeze instruction to the target background process, so that the target background process is closed and cannot be started.

205. The terminal device monitors whether an application that depends on the target background process starts.

In the embodiment of the present invention, the terminal device performs freezing on the process level. When the user operates the application from the terminal device, the user cannot find whether one or more processes corresponding to the application have been frozen, and thus may use the terminal for the user. The application in the device is bothered. Therefore, the terminal device needs to monitor whether there is an application startup that depends on the target background process (the frozen background process), and if so, ask the user whether to unfreeze the background process to ensure the normal use of the application.

206. If an application that depends on the target background process is started, the terminal device sends a prompt message to the user to ask the user whether to unfreeze the target background process.

In the embodiment of the present invention, when the terminal device detects that an application that depends on the frozen background process is started, a prompt message is sent to the user to ask the user whether to unfreeze the background process, so that the application can be used normally.

In the method described in FIG. 2, the terminal device may filter the background process to be frozen in the currently running background process according to the freezeable background process list preset by the user or the evaluation of the security process by the security software, and then stop the background process. , sends a freeze instruction to the background process, causing it to close and fail to start. After the background process is frozen, if it is detected that an application dependent on the background process is started, a prompt message is sent to the user to ask whether the background process is to be thawed, so that the application can be used normally. It can be seen that the implementation of the method can make the unnecessary and malicious background processes freeze and cannot be started, thereby saving memory, saving power and data traffic, and preventing the user's personal information and private data from being stolen. In addition, the terminal device can prompt the user to unfreeze the background process in time, so as not to affect the normal use of the application that the user wants to use.

Optionally, the processor 508 may include one or more processing units; preferably, the processor 508 may integrate an application processor and a modem processor, where the application processor mainly processes an operating system, a user interface, an application, and the like. The modem processor primarily handles wireless communications. It will be appreciated that the above described modem processor may also not be integrated into the processor 508.

The handset also includes a power source 509 (such as a battery) that supplies power to the various components. Preferably, the power source can be logically coupled to the processor 508 via a power management system to enable management of charging, discharging, and power management functions through the power management system.

Although not shown, the mobile phone may further include a camera, a Bluetooth module, and the like, and details are not described herein again.

In the foregoing embodiment, each step method flow may be implemented based on the structure of the terminal device. Both the application layer and the operating system kernel can be considered as part of the abstraction structure of the processor 508.

In the embodiment of the present invention, the processor 508 performs the following operations by calling program code stored in the memory 502:

Select the target background process from the currently running background process; wherein the target background process is a non-essential or malicious background process;

Stop the above target background process from running;

A freeze instruction is sent to the target background process described above so that the target background process is closed and cannot be started.

As an alternative embodiment, the processor 508 is further configured to perform the following operations by calling program code stored in the memory 502:

Monitor whether there is an application launch that depends on the target background process described above;

If an application that depends on the target background process is started, a prompt message is sent to the user to ask the user whether to unfreeze the target background process.

In the terminal device shown in FIG. 5, the processor 508 can filter the currently running background process at the time of startup or when a new background process occurs by calling the program code stored in the memory 502, wherein the terminal device can be based on the user. Pre-set the list of freezeable background processes or the evaluation of the background process by the security software to filter out the background processes that need to be frozen in the currently running background process. After selecting the background process to be frozen, the terminal device stops the background process, sends a freeze instruction to the background process, and causes it to be closed and cannot be started. It can be seen that with the terminal device, unnecessary and malicious background processes can be frozen and cannot be started, thereby saving memory, saving power and data traffic, and preventing the user's personal information and private data from being stolen.
