[0049] Exemplary embodiments will be described in detail herein, examples of which are illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numerals in different figures represent identical or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of this disclosure, as detailed in the appended claims.

[0050] The present disclosure provides a method for protecting user privacy information. Figure 1 , Figure 1 FIG. 1 is a flow chart showing a method for protecting user privacy information according to an exemplary embodiment. Figure 1 As shown, this method includes:

[0051] Step S11: When it is detected that the caller application is running in the background and the callee is subject to permission restrictions in a cross-application call, an option for closing the caller application is displayed; Step S12: After receiving touch information for the option for closing the caller application, the operation of the caller application is terminated.

[0052] The callee is an application, such as a contact application, a photo album application, a call log application, etc. Alternatively, the callee is a system service, such as a location service or a recording service.

[0053] In this embodiment, when the calling application runs in the background during a cross-application call and the called application is subject to permission restrictions, a way is provided to the user to close the application, giving the user control over closing the application, thereby protecting the user's personal privacy information.

[0054] The present disclosure provides a method for protecting user privacy information, which includes: Figure 1 The method shown also includes: displaying an option for maintaining the caller application, and maintaining the operation of the caller application after receiving touch information for the option for maintaining the caller application.

[0055] In one embodiment, the option for closing the calling application is displayed while the option for maintaining the calling application is displayed, for example, the two options are displayed simultaneously in the same notification box.

[0056] In this embodiment, when it is detected that the caller application is running in the background and the callee application is subject to permission restrictions in a cross-application call, in addition to providing the user with a way to close the caller application, the user is also provided with a way to maintain the caller application, so that the user has control over the caller application and can close or maintain the caller application according to usage needs.

[0057] A method for protecting user privacy information is provided in an embodiment of the present disclosure. This method includes the method in the previous embodiment, and also includes: displaying more than one permission restriction setting option, different permission restriction setting options corresponding to different permission restriction levels, and setting the permission restriction level according to the permission restriction setting option selected by the user.

[0058] In one embodiment, after receiving touch information for the option to maintain the caller application, one or more permission restriction level setting options are displayed. Alternatively, when no cross-application call is detected and the callee application is running in the background and permission restrictions are involved, one or more permission restriction level setting options are displayed. Alternatively, after powering on or restarting the device, one or more permission restriction level setting options are displayed.

[0059] In one embodiment, the permission restriction degree setting option includes: a first degree setting option and a second degree setting option.

[0060] The first degree setting option corresponds to the following method for determining the running location of the caller application: querying a foreground running application set in the activity management service, and when the caller application belongs to the foreground running application set, determining that the caller application is running in the foreground; when the caller application does not belong to the foreground running application set, determining that the caller application is running in the background;

[0061] The second-level setting option corresponds to the following method for determining the running location of the caller application: determining the process of the caller application, and when the process of the caller application belongs to the set of running processes maintained in the permission management service, determining that the caller application is running in the foreground; when the process of the caller application does not belong to the set of running processes maintained in the permission management service, determining that the caller application is running in the background.

[0062] The first-level setting option corresponds to the following method for determining the running location of the calling application: the applications included in the foreground running application set in the activity management service are applications that receive user interaction information, or are the applications that are at the forefront of the current display interface. Applications that are not displayed on the current interface but are running and have interactive output are not included in the foreground running application set in the activity management service. For example, an application that is not displayed on the current interface but is running and outputting audio data is not included in the foreground running application set in the activity management service.

[0063] The second level setting option corresponds to the following method for determining the running location of the calling application. An application that is not displayed on the current interface but is running and has interactive output belongs to the foreground application. For example, an application that is not displayed on the current interface but is running and outputs audio data belongs to the foreground application.

[0064] In this embodiment, the method for determining whether the application is running in the foreground is adjusted, and the conditions for determining whether the application is running in the foreground are adjusted, so that the user has the control right to adjust the degree of permission restriction.

[0065] The present invention provides a method for protecting user privacy information. Figure 1 The method shown, and in step S11, it is detected that the calling application in the cross-application call is running in the background and the called application involves permission restrictions;

[0066] The detection that the calling application in the cross-application call is running in the background and the called party is involved in permission restrictions includes: the permission management service receives call information of the management class instant call function, or receives call information of the management class continuous call function; determines that the calling application in the call information is running in the background and the called party is involved in permission restrictions.

[0067] In one embodiment, determining whether the called party involves permission restrictions includes: when the called party is an application, determining whether the called party belongs to a set application set; when the called party belongs to a set application set, determining that the called party involves permission restrictions; when the called party does not belong to a set application set, determining that the called party does not involve permission restrictions. When the called party is a system service, determining whether the called party belongs to a set service set; when the called party belongs to a set service set, determining that the called party involves permission restrictions; when the called party does not belong to a set service set, determining that the called party does not involve permission restrictions. The set application set includes system default applications involving permission restrictions, and / or user-marked applications involving permission restrictions. The set service set includes system default services involving permission restrictions, and / or user-marked services involving permission restrictions.

[0068] In this method, the permission management service in the framework layer is improved so that the permission management service can detect that the caller application is running in the background and the callee is involved in permission restrictions in a cross-application call, and a permission management application is set in the application layer so that the permission management application assists in displaying the option for closing the caller application. The corresponding management service of the callee in the framework layer receives a call request and calls the corresponding calling function when verifying the permission. The permission management service learns of the call and the caller application and the callee of the calling function, determines the identification information of the caller application based on the caller application, determines the representation information of the callee based on the callee, and notifies the permission management application of the determination of the representation information of the callee (for example, notifying the permission management application in an asynchronous and cross-process manner). The permission management application learns the identification information of the caller application and determines the entry to close the caller application.

[0069] In this embodiment, obtaining a cross-application call operation includes: receiving call information of an instant call function of the application operation management (AppOpsManager) class, or receiving call information of a continuous call function of the application operation management (AppOpsManager) class.

[0070] The continuously called function is the startOp function, an Application Programming Interface (API) in the AppOpsManager class. The StartOp function's parameters include the operation name (op) in string format, the source identifier (uid) in integer format, and the package name (packageName) in string format. The operation name is the name of the called application, the source identifier is the caller's application code, and the package name is the unique identifier of the calling application in the system. The StartOp function is used to execute calls continuously for a certain duration.

[0071] The instantaneous call function is the noteOp function, which is an application programming interface (API) in the AppOpsManager class. The parameters of the noteOp function include: the operation name (op) in string format, the source identifier (uid) in integer format, and the package name (packageName) in string format. The operation name refers to the name of the called party, the source identifier is the label code of the caller application, and the package name refers to the unique identifier of the caller application in the system. The function corresponding to the StartOp function is a single execution call.
