Detailed Description
The following description of the embodiments of the present application will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are only some, but not all, of the embodiments of the present application. All other embodiments, which can be made by one of ordinary skill in the art based on the embodiments herein without making any inventive effort, are intended to be within the scope of the present application.
In some electronic devices, microphones are among the devices with higher usage. For example, in a smart phone or tablet or smart watch, a microphone may be used to collect the user's voice during a conversation for delivery to the opposite end of the communication. With the increase of the intelligentization degree of the electronic device, more types of application programs are installed in the electronic device, and the application programs also use a microphone or collect voice data of a user in the running process.
For example, for an application program of the instant chat class, a microphone may be invoked to collect voice data of a user to generate a voice short message to send to other users. For example, for applications of the singing class, the voice data of the user may be collected during operation as an audio file entered by the user. For another example, the application program for the image acquisition class may acquire voice data of the user as dubbing content of the image at the same time in the process of image acquisition.
However, after research on related applications that call a microphone, the inventor finds that some applications call the microphone privately to collect voice without the user's knowledge, and thus information leakage of the user is caused.
Therefore, the inventor provides the application program detection method, the application program detection device and the electronic equipment, and when the application program in the specified state is detected, whether the application program belongs to a control application program which collects user voice data when the authorization is not acquired is detected, if so, the control grade of the application program is determined, and then the application program is controlled based on the control grade. By detecting the state of the application program, when the application program is in the specified state, whether the application program is a control application program or not can be further determined, so that the application program can be controlled based on the control level, the application program which is maliciously collected with user voice data can be controlled more flexibly, and the probability of user information leakage is reduced.
Embodiments of the present application will be described in detail below with reference to the accompanying drawings.
Referring to fig. 1, an application program detection method provided in an embodiment of the present application includes:
s110: when an application program in a specified state is detected, whether the application program belongs to a control application program or not is detected, wherein the control application program comprises an application program which collects user voice data when authorization is not acquired.
It should be noted that, in the embodiment of the present application, the state indicates a state before the application program will call the state of the microphone, or a state before the state where the voice data collected by the microphone will be obtained. The former state is understood to be the state that is further forward in the operation sequence. For example, the application may enter state a first, then enter state B after state a, and then state a is the previous state for state B. Furthermore, in order to effectively control an application program which can call a microphone or acquire voice data acquired by the microphone, the running state or the installation state can be configured to be a designated state, and when the running state or the installation state of the application program is detected, the application program is determined to be in the designated state.
The operation state may include a foreground operation or a background operation. It should be noted that, in this embodiment, the application running in the foreground refers to an application with an interface that can interact with a user, for example, when the user uses the instant messaging software to chat, the interface of the instant messaging software may be used to interact with the user to input text information or voice information, and in this case, the instant messaging software is the application running in the foreground. Correspondingly, when the application program does not have an interface which can interact with the user and is still in an operation state, the application program is operated in the background, for example, when the user switches the interface which is currently displayed from the interface of the instant messaging software to the desktop, the instant messaging software is the application program operated in the background.
Alternatively, as a way, according to the mechanism of the Android system, one application may run multiple processes, and all the processes correspond to one process priority, where the process priority may correspond to a state (a foreground running state, a background running state, etc.) where an application program to which the process belongs is currently in the system. When an interface of an application is being displayed, then the priority of the process running the interface is impurtance_foregroup=100. While the Android system allows the application to obtain the priorities of all the processes of the current application itself when running, by using the principle, the electronic device can traverse the priorities of all the processes of the application, and when detecting that a process priority=impurtance_foregroup exists in the processes included in the application, it determines that the application is running in the FOREGROUND.
The installation state may include an installation state when the application is first installed, or may be an installation state when the update file of the application is installed.
When it is detected that an application is in a specified state, it can be further determined whether the application belongs to a management application. In one manner, the electronic device may store a list of applications that belong to the administration application, and in this manner, the electronic device may determine whether an application in a specified state belongs to the administration application by querying the list of applications.
It should be noted that, in the embodiment of the present application, an application that collects user voice data when no authorization is obtained may be understood as an application that automatically invokes a microphone to collect user voice data. Wherein automatically invoking the microphone comprises invoking the microphone in response to an automation event, but the automation event is not configured by the user.
S120: and if the application program belongs to the control application program, determining the control level of the application program.
Alternatively, the level of control of the application may be determined based on the identity of the application in the specified state. In this way, all the control levels corresponding to the control applications can be preconfigured, and then after the control applications in the specified state are obtained, the control levels of the applications in the specified state are determined by querying the preconfigured control levels.
S130: and controlling the application program based on the control level.
It should be noted that, even though the applications belong to the control application, the applications belonging to the control application may correspond to different control levels, so as to perform targeted control, because the actions of calling the microphone or acquiring the voice data collected by the microphone are different. By way of example, some applications may only occasionally have unauthorized access to the microphone, but some applications may access the microphone at a higher frequency, and for those applications that may occasionally have unauthorized access to the microphone, the higher frequency access to the microphone may be better for those applications that may have unauthorized access to the microphone than for those applications that may have unauthorized access to the microphone, since the higher frequency access to the microphone may be better for those applications that may have a greater probability of stealing the user's private information.
As one way, the larger the number corresponding to the control level, the more strict the corresponding control manner. For example, if the control level is the first level, the number corresponding to the control level is 1, if the control level is the first level, the number corresponding to the control level is 2, and if 2 is greater than 1, the control mode corresponding to the second level is more strict than the control mode corresponding to the first level.
In this way, if the control level of the application is the first level, a prompt message about the application may be triggered. In this way, when the electronic device executing the method provided by the embodiment detects that the application program in the specified state belongs to the control application program and the corresponding control level is the first level, the prompting information shown in fig. 2 is triggered, so as to prompt the user that the application program in the specified state has the possibility of collecting the voice data of the user in a private manner. As shown in fig. 2, the electronic device may display a pop-up box 99 to display a prompt for "application a is using your microphone". Optionally, the electronic device may further configure an option control in the displayed alert information, so that the user selects whether to ignore the behavior of application a or to block the behavior of application a. As shown in fig. 3, if the user is detected to touch the control with the name "ignore", the electronic device does not take any measure to the application program, and if the user is detected to touch the control with the name "block", the electronic device kills the process of the application program a.
And if the control level of the application program is the second level, prohibiting the application program from acquiring the user voice data. It should be noted that, there may be various ways to collect the user voice data for an application program that does not obtain the authorization and collects the user voice data. Alternatively, the microphone may be invoked directly to collect the user's voice data in real time, or alternatively, a folder storing the user's voice data may be looked up directly in the electronic device, and then the folder is accessed privately to obtain the user's voice data. Correspondingly, prohibiting the application from acquiring the user voice data may include prohibiting the application from invoking the microphone and prohibiting the application from accessing a folder for storing the voice data acquired by the microphone.
According to the application program detection method, when the application program in the specified state is detected, whether the application program belongs to the control application program which is not authorized and collects the user voice data is detected, if so, the control level of the application program is determined, and then the application program is controlled based on the control level. By detecting the state of the application program, when the application program is in the specified state, whether the application program is a control application program or not can be further determined, so that the application program can be controlled based on the control level, the application program which is maliciously collected with user voice data can be controlled more flexibly, and the probability of user information leakage is reduced.
Referring to fig. 4, an application program detection method provided in an embodiment of the present application includes:
s210: when an application program in a specified state is detected, whether the application program belongs to a control application program or not is detected, wherein the control application program comprises an application program which collects user voice data when authorization is not acquired.
S220: and if the user voice data acquisition behavior belongs to the control application program, acquiring a first control strategy acquired from a server in advance, wherein the first control strategy is generated by the server based on feedback of the user voice data acquisition behavior of the application program.
In one mode, the electronic device may detect an application program that does not acquire authorization and collects voice data of the user, and further feed back a detection result to the server, so that the server may generate the first control policy after receiving the application program that does not acquire authorization and collects voice data of the user and is fed back by the plurality of electronic devices. Optionally, the first management and control policy includes a management and control application program and a management and control level corresponding to each management and control application program.
The electronic device may determine whether the application program has an unauthorized act of collecting user voice data in a number of ways.
In one mode, the electronic device may trigger a prompt when detecting that an application is calling the microphone, and if detecting that the user does not feed back the prompt, determine that the application has a behavior of acquiring voice data of the user without obtaining authorization. The form of the prompt information includes, but is not limited to, triggering a pop-up box to prompt and prompting through a short message.
Alternatively, the electronic device may determine whether the application has unauthorized activity to collect user voice data by detecting whether the activity of the calling microphone is triggered by the user. The inventor researches that if the action of calling the microphone is triggered by the user, an operation interface is usually displayed first, and then the user can trigger the application program to call the action of the microphone by operating on the operation interface. For example, for an application program of the recording class, an operation interface including a recording start control is displayed after the application program is started, and when the user is detected to touch the recording start control, the electronic device is triggered to call a microphone to collect voice data of the user. For another example, for applications of the talk class, after detecting that the user has completed dialing and triggering the talk control, the electronic device may begin to invoke the microphone to collect user voice data.
In this way, the electronic device may store the operation interface provided with the control for triggering the invoking microphone so as to detect whether the operation interface provided with the control for triggering the invoking microphone is running in the foreground when the microphone is invoked or whether the operation interface provided with the control for triggering the invoking microphone belongs to an interface in which the history is running in the foreground when the microphone is invoked (an interface in which the history is running in the foreground will be described later).
If the operation interface provided with the control for triggering the calling microphone is detected to be in the foreground operation when the microphone is called, the action of calling the microphone by the application program is judged to be triggered by a user, otherwise, the action of calling the microphone by the application program is judged to be performed without obtaining authorization.
If the operation interface provided with the control for triggering the calling microphone is detected to belong to the interface which runs in the foreground with the latest history when the microphone is called, the action of calling the microphone by the application program is judged to be triggered by a user, otherwise, the action of calling the microphone by the application program is judged to be performed without obtaining authorization.
The interface shown above where the history is newly run in the foreground will be described below by way of example.
As one way, each interface in the electronic device is configured with an interface name and an application identifier to which it belongs. In this way, the electronic device may store the running interfaces sequentially according to the running order, and the running time corresponding to the interface that is further back in the running order is closer to the current time, so that the interface whose corresponding running time is closest to the current time is determined as the interface that is running in the foreground with the latest history. As shown in fig. 5, fig. 5 shows an interface 10, an interface 11, an interface 12, an interface 13, an interface 14, and an interface 15, where the operation time (may be understood as a start time) corresponding to the interface 10 is T6, the operation time (may be understood as a start time) corresponding to the interface 11 is T5, the operation time (may be understood as a start time) corresponding to the interface 12 is T4, the operation time (may be understood as a start time) corresponding to the interface 13 is T3, the operation time (may be understood as a start time) corresponding to the interface 14 is T2, and the operation time (may be understood as a start time) corresponding to the interface 15 is T1. In addition, as can be seen from fig. 5, the interface with the corresponding running time closest to the current time is the interface 10, and thus, it can be determined that the interface 10 is the interface that has been running in the foreground most recently.
The interface nearest to the current moment can be determined by a time difference mode. Specifically, the running time corresponding to each interface is differenced from the current time to obtain a time difference value between the running time of each interface and the current time, and then the interface with the smallest corresponding time difference value is used as the interface with the closest running time to the current time.
S230: and determining a control level of the application program based on the first control strategy.
S240: and controlling the application program based on the control level.
As shown in the foregoing, after the server generates the first management policy according to the received application program that is fed back by the plurality of electronic devices and that is not authorized to collect the voice data of the user, the electronic device executing the embodiment of the present application may also send, when detecting that the application program that is not authorized to collect the voice data of the user exists, the application program that is not authorized to collect the voice data of the user to the server, so that the server generates the first management policy.
The server also screens and cleans data uploaded by the plurality of electronic devices in the process of generating the management and control strategy, so as to determine which application programs are determined to be management and control application programs.
As one way, the server may determine whether to determine the application as a policing application for the number of times that there is a behavioral application that invokes a microphone to obtain user voice data without obtaining authorization. It should be noted that, if some applications may trigger the call to the microphone only accidentally or call to the microphone due to a running error, the server may not count too many times, although there is a behavior of calling the microphone without obtaining authorization for these applications, which may be caused by the running error only accidentally. For example, for the same application, there may be only a single electronic device reporting that there is an unauthorized action to call the microphone, but most electronic devices that also install the application will not report that there is an unauthorized action to call the microphone, so in order to improve the accuracy of application control, such applications will not be determined to be control applications.
In this way, the server may count the total fed back times corresponding to the application program that is reported to have the unauthorized microphone behavior, and then determine the application program whose corresponding feedback times are greater than the threshold times as the management application program.
Optionally, the server may further determine a control level corresponding to the application program according to the magnitude of the corresponding feedback times exceeding the threshold times. As a way, the server may configure a plurality of amplitude intervals corresponding to the threshold number of times, where each amplitude interval corresponds to a control level, and when the obtained feedback number of times corresponding to the application program is greater than the threshold number of times, match the difference between the feedback number of times and the threshold number of times with the plurality of amplitude intervals, so as to determine the control level corresponding to the matched amplitude interval as the control level of the application program.
Illustratively, as shown in fig. 6, N represents the number of feedback times. Optionally, N1 corresponds to a threshold number of times. N1 to N2 are one amplitude interval, N2 to N3 are one amplitude interval, and N3 to N4 are one amplitude interval. If the difference between the feedback times corresponding to the application program and the threshold times is detected to be greater than N2 but less than N3, determining that the amplitude interval from N2 to N3 is the matched amplitude interval, and further determining the control level corresponding to the amplitude interval from N2 to N3 as the control level of the application program.
Alternatively, the server may determine whether to determine the application as a policing application for the frequency with which a behavioural application that invokes a microphone to obtain user speech data is fed back for the presence of an unauthorized acquisition. It should be noted that, there may be no behavior of calling the microphone without obtaining authorization before some application program, but there is a behavior of calling the microphone without obtaining authorization after updating to a certain version, in this case, if it is still determined whether to determine the application program as the control application program through the total feedback times, the application program that suddenly has a behavior of calling the microphone without obtaining authorization to obtain the user voice data may not be controlled immediately.
In this manner, the server may determine to be a frequency threshold, and then determine as a policing application, the application for which the corresponding feedback frequency is greater than the frequency threshold. The frequency threshold may be a frequency of feedback per hour greater than a predetermined threshold, a frequency of feedback per day greater than a predetermined threshold, or a frequency of feedback per week greater than a predetermined threshold. Similarly, the server may also determine the corresponding control level of the application program, in particular, based on the corresponding feedback frequency exceeding the threshold frequency magnitude. As a way, the server may configure a plurality of amplitude intervals corresponding to the threshold frequency, where each amplitude interval corresponds to a control level, and when the feedback frequency corresponding to the application program is obtained to be greater than the threshold frequency, match the difference between the feedback frequency and the threshold frequency with the plurality of amplitude intervals, so that the control level corresponding to the matched amplitude interval is determined as the control level of the application program.
According to the application program detection method, when the application program in the specified state is detected, whether the application program belongs to the control application program which collects user voice data when authorization is not obtained is detected, if the application program belongs to the control application program, a first control strategy which is obtained in advance from a server is obtained, so that the control grade of the application program is determined based on the first control strategy, and further the application program is controlled based on the control grade. By detecting the state of the application program, when the application program is in the specified state, whether the application program is a control application program or not can be further determined, so that the application program can be controlled based on the control level, the application program which is maliciously collected with user voice data can be controlled more flexibly, and the probability of user information leakage is reduced.
Referring to fig. 7, an application program detection method provided in an embodiment of the present application includes:
s310: when an application program in a specified state is detected, whether the application program belongs to a control application program or not is detected, wherein the control application program comprises an application program which collects user voice data when authorization is not acquired.
S320: and if the user voice data acquisition behavior belongs to the control application program, acquiring a first control strategy acquired from a server in advance, wherein the first control strategy is generated by the server based on feedback of the user voice data acquisition behavior of the application program.
S330: and acquiring a local second management and control strategy.
It should be noted that, in this embodiment, the second management policy may be directly generated according to an application program that is locally detected and that collects user voice data when no authorization is obtained, or may be generated according to the first management policy obtained from the server. Optionally, for the same application, the level of policing in the second policing policy is lower than the level of policing in the first policing policy. For example, the first management policy includes an application a, an application B, and an application C. The control level corresponding to the application program A is a first level, and the control level corresponding to the application program B and the application program C is a second level. In this case, if the second control policy is generated based on the first control policy, optionally, the application a does not need to perform control, and the control levels corresponding to the application B and the application C are the first level.
S340: and determining the control level of the application program based on the first control strategy and the second control strategy.
As one way, the determining the control level of the application program based on the first control policy and the second control policy includes: determining a control priority of the first control strategy and the second control strategy; if the control priority corresponding to the first control strategy is higher than the control priority of the second control strategy, determining the control level of the application program based on the first control strategy; and if the control priority corresponding to the second control strategy is higher than the control priority of the first control strategy, determining the control level of the application program based on the second control strategy.
Wherein, optionally, the determining the control priority of the first control policy and the second control policy includes: acquiring a current system mode; if the system mode is a visitor mode, determining that the control priority of the second control strategy is higher than that of the first control strategy; and if the system mode is a master mode, determining that the control priority of the first control strategy is higher than that of the second control strategy.
It should be noted that the user of the electronic device may also configure to control other users using the electronic device. For example, the user of the electronic device is a parent, and the child using the electronic device is expected to be managed, in this case, the electronic device may select a specific management and control policy according to the current actual running state, so as to implement more flexible application management and control.
