Description

Technical Field

[0001] The present application relates to the field of application technology, and in particular to a privacy protection method, apparatus, device and storage medium for an application. Background Art

[0002] The background of a smartphone can automatically retain the application process. Generally, when the user exits the application, the application process will be kept running in the background, so that when the user reopens the application, the application interface can be directly restored to the time when the user exited.

[0003] The above-mentioned background retention mechanism can bring a convenient experience to users, but at the same time it also creates the risk of privacy leakage. For example, when a user uses the screen projection or screen sharing functions of a smartphone at work, once the application is running in the background, when the application is opened, the content of the previously browsed page will be directly exposed in the screen projection or screen sharing, causing privacy leakage. Summary of the invention

If the identifier of the application matches the identifier of any application in the privacy protection list, the background process of the application is closed to clear the browsing traces of the application.

[0009] The embodiment of the present application also discloses a privacy protection device for an application program, which is applied to a mobile terminal and includes:

[0010] A background monitoring module, used to obtain the identification of an application when it is detected that an application is running in the background;

[0011] A list monitoring module is used to obtain the identifiers of applications in the privacy protection list;

[0012] A process management module is used to match the identifier of the application with the identifier of any application in the privacy protection list. If the identifier of the application matches the identifier of any application in the privacy protection list, the background process of the application is closed to clear the browsing traces of the application.

[0022] Please refer to Figure 1 The present application embodiment discloses a privacy protection method for an application program, which is applied to a mobile terminal and includes the following steps:

[0023] S101: when it is detected that an application is running in the background, obtaining an identification of the application;

[0024] S102: Obtaining the identifier of the application in the privacy protection list;

[0025] S103: Match the identifier of the application with the identifier of any application in the privacy protection list. If the identifier of the application matches the identifier of any application in the privacy protection list, close the background process of the application to clear the browsing traces of the application.

[0026] When the embodiment of the present application detects that an application is running in the background, the identification of the application is obtained; the identification of the application in the privacy protection list is obtained; the identification of the application is matched with the identification of any application in the privacy protection list, and if the identification of the application matches the identification of any application in the privacy protection list, the background process of the application is closed. The embodiment of the present application can monitor the relevant applications and close the background processes in time according to the privacy protection list set by the user, so as to clear the user's browsing traces of the application and avoid the user directly exposing the previous browsing traces when opening the application again.

[0027] The execution subject of the privacy protection method of the application described in the embodiment of the present application is a mobile terminal, such as a smart phone, a tablet, etc.

[0028] In step S101, it is monitored whether there is an application running in the background, and when it is detected that there is an application running in the background, an identifier of the application is obtained.

[0029] Taking the Android system as an example, each APP has an APP identifier (UID), and the APP processes running in the system will also be marked with the corresponding APP identifier. Therefore, the APP identifier can be used to determine which APP the running process in the system belongs to. When multiple APP processes are running simultaneously in the mobile terminal, different APP processes have different priorities. The APP with the highest priority is displayed on the interactive interface of the mobile terminal, that is, it is in the foreground; while other processes with relatively low priorities will not be displayed on the interactive interface of the mobile terminal, that is, they are in the background. Therefore, when it is necessary to monitor whether there is an application running in the background, the process information running in the system can be obtained, and the priority information of the process can be used to determine whether it is the highest priority. If it is not the highest priority, it means that the process is running in the background, so that it can be determined that there is an application running in the background, otherwise it is determined that there is no application running in the background. Further, when it is detected that there is an application running in the background, the APP identifier of the process of the application is obtained.

[0030] In one embodiment, when it is detected that an application is running in the background, the step of obtaining the identification of the application includes:

[0031] It is monitored whether there is an application running in the background according to a preset period, and when it is detected that there is an application running in the background, an identifier of the application is obtained.

[0032] This embodiment performs monitoring according to a preset period, wherein the preset period can be set according to the situation, for example, set to 0.2 seconds, then the running process information in the system is obtained every 0.2 seconds and it is determined whether there is a process running in the background.

[0033] Please refer to Figure 2 In one embodiment, when it is detected that an application is running in the background, before the step of obtaining the identification of the application, the method further includes:

[0034] Step S100: Acquire usage status information of the mobile terminal; the usage status information is used to indicate the degree of privacy of the use of the mobile terminal; if the usage status information of the mobile terminal is preset status information, monitor whether there is an application running in the background.

[0035] In this embodiment, it is first determined whether the use environment of the mobile terminal is private. When the privacy level of the mobile terminal is not enough, the privacy protection of the applications in the privacy protection list is performed, that is, the background process is monitored and closed; if the privacy level can meet certain requirements, there is no need to perform privacy protection on the applications in the privacy protection list. Specifically, it is determined by obtaining the use status information of the mobile terminal. When the use status information of the mobile terminal is the preset status information, it means that the privacy level of the use environment of the mobile terminal is not enough, and privacy protection is required. The use status information is used to indicate the use privacy level of the mobile terminal; the preset status information is used to indicate that the use privacy level of the mobile terminal is low or lower than the user's requirements, which can be set according to the situation. It should be noted that in different situations, the situations that may cause privacy exposure are different, and the focus of the use status information may also be different. Specifically, it can be determined according to the actual scenario which information of the mobile terminal is set as the use status information and monitored. For example, when considering the scenario of screen projection or screen sharing, the permission status information of the screen recording permission of the mobile terminal system is the object that needs to be monitored, which is the use status information that needs to be monitored.

[0036] In a specific embodiment, the step of obtaining the usage status information of the mobile terminal in step S100 includes:

[0037] Get the system's screen recording permission status information;

[0038] If the usage status information of the mobile terminal in step S100 is the preset status information, the step of monitoring whether there is an application running in the background includes:

[0039] If the permission status information is authorization status information, it is monitored whether there is an application running in the background.

[0040] This embodiment specifically provides protection for scenarios such as screen projection or screen sharing that may cause the exposure of application browsing privacy. In this scenario, by obtaining the permission status information of the system's screen recording permission, it is determined whether the system's screen recording permission is authorized. If the permission status information of the screen recording is authorized, it means that the mobile terminal is using sensitive functions such as screen projection or screen sharing. At this time, the privacy level of the mobile terminal is low, so it is necessary to protect the privacy of the applications in the privacy protection list.

[0041] In one embodiment, the privacy protection method of the application further includes the steps of:

[0042] When receiving a closing instruction or an opening instruction from the user, in response to the closing instruction, stop monitoring whether there is an application running in the background; in response to the opening instruction, monitor whether there is an application running in the background.

[0043] In this embodiment, the user can choose whether to perform privacy protection. The user can turn on the privacy protection function when privacy protection is needed, otherwise the privacy protection function can be turned off to avoid clearing the background process of the application program when it is unnecessary, which affects the user experience.

[0044] For step S102, the identifier of the application in the privacy protection list is obtained;

[0045] Among them, the privacy protection list is a list for storing the identifiers of applications that need privacy protection, which can be a database or data table in the memory of the mobile terminal. The privacy protection list can be embodied in a visual form in the mobile terminal, and the relevant interactive design can be carried out as needed, so that the privacy protection list can intuitively display the applications saved therein in the interactive interface of the mobile terminal. Furthermore, the privacy protection list can be designed as a window component on the desktop of the mobile terminal, wherein a number of controls are provided in the window component for responding to user operations, obtaining the identifiers of applications that the user wants to protect privacy according to the user's operating instructions, and adding them to the database or data table, thereby protecting the privacy of the relevant applications, and the privacy protection function can also be turned off or on according to the user's operating instructions.

[0046] Please refer to Figure 3 In one embodiment, the privacy protection method of the application further comprises the steps of:

[0047] S104: When receiving the user's adding instruction, monitoring the user's selection operation on any application on the mobile terminal; obtaining the identifier of the selected application, and recording the identifier of the application in the privacy protection list.

[0048] This embodiment implements privacy protection by allowing users to add applications to a privacy protection list. Specifically, the adding instruction can be issued by adding a control. The adding control can be set in the above-mentioned desktop window component or in a setting page of a mobile terminal. This embodiment obtains the identifier of the selected application according to the user's selection, and records the identifier of the application in the privacy protection list, thereby performing privacy protection on the application selected by the user.

[0049] For step S103, the identifier of the application is matched with the identifier of any application in the privacy protection list. If the identifier of the application matches the identifier of any application in the privacy protection list, the background process of the application is closed to clear the browsing traces of the application.

[0050] In this step, when the identifier of the application running in the background matches the identifier of any application in the privacy protection list, it means that the application running in the background is the application that needs privacy protection, so the background process of the application is closed to clear the browsing traces left by the user in the application. After the background process of the application is closed, the next time the user opens the application, it will not be restored to the browsing page when exiting, but the initialized welcome page will be displayed. Therefore, the exposure of the user's browsing traces in the application is avoided.

[0051] In one embodiment, in step S103, if the identification of the application matches the identification of any application in the privacy protection list, the step of closing the background process of the application includes:

[0052] If the identifier of the application matches the identifier of any application in the privacy protection list, obtaining the current time;

[0053] If the current time is within a preset privacy protection time period, the background process of the application is closed.

[0054] In this embodiment, the user can set a privacy protection time period. Only during the set privacy protection time period will privacy protection be performed and the background process of the application program be closed; otherwise, privacy protection will not be performed and the background process of the application program does not need to be closed. The privacy protection time period can be set according to user needs, for example, it can be set to the time period of 15:00-17:00.

[0055] In another embodiment, if the identification of the application matches the identification of any application in the privacy protection list, the step of closing the background process of the application includes:

[0056] If the identifier of the application matches the identifier of any application in the privacy protection list, obtaining the duration of the application running in the background;

[0057] If the duration exceeds a preset time threshold, the background process of the application is closed.

[0058] Considering that in some cases the user does not really want to exit the application, but accidentally triggers the exit, or sometimes the user only temporarily switches the application, but does not want the background process of the application to be closed immediately. Therefore, in this embodiment, the user can set a time threshold, and the background process of the application will only be closed when the duration of the application running in the background exceeds the preset time threshold, otherwise it will not be closed. Among them, the duration of the application running in the background is calculated from the time when the application is monitored to be running in the background; the preset time threshold can be set according to user needs, for example, set to 10 seconds. In one example, the preset time threshold is set to 10 seconds. Therefore, as long as the user exits the application and opens the application again within 10 seconds, the duration of the application running in the background does not exceed 10 seconds, and the background process of the application will not be closed.

[0059] In one embodiment, the judgment can be made in combination with the two conditions of duration and preset time period, and if the identification of the application matches the identification of any application in the privacy protection list, the step of closing the background process of the application includes:

[0060] If the identifier of the application matches the identifier of any application in the privacy protection list, obtaining the current time and the duration of the application running in the background;

[0061] If the current time is within the preset privacy protection time period and the duration exceeds a preset time threshold, the background process of the application is closed.

[0062] In this embodiment, the background process of the application is closed only when the duration of the application running in the background exceeds the preset time threshold and is within the preset privacy protection time period, otherwise the background process of the application is not closed. The user can set the privacy protection time period and the preset time threshold according to the actual situation, so that the privacy protection function better meets the actual privacy protection needs and brings the user a better user experience.

[0063] Please refer to Figure 4 The embodiment of the present application also discloses a privacy protection device for an application program, which is applied to a mobile terminal and includes:

[0064] The background monitoring module 201 is used to obtain the identification of the application when it is detected that there is an application running in the background;

[0065] A list monitoring module 202, used to obtain the identifiers of the applications in the privacy protection list;

[0066] The process management module 203 is used to match the identifier of the application with the identifier of any application in the privacy protection list. If the identifier of the application matches the identifier of any application in the privacy protection list, the background process of the application is closed to clear the browsing traces of the application.
