All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The terms "first," "second," "third," "fourth," and the like in the description and in the claims, as well as in the drawings, if any, are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used are interchangeable under appropriate circumstances such that the embodiments of the invention described herein are capable of other sequential examples than those illustrated or described.

At present, the operating system of the terminal is generally an open platform, and its open interface allows various applications to be implanted and run, and also allows the user to actively download various applications. However, various application programs written based on the operating system of the terminal need to apply for acquiring application functions and have numerous hardware rights, so that malicious application programs can take advantage of the application functions. Generally, a malicious application program runs in a background, and steals privacy information of a user by controlling software and hardware of the terminal, for example, a camera is started to steal multimedia data such as scene videos or pictures around the terminal under the condition that the user does not know or is not authorized by the user, so that the leakage of the privacy data is caused. The privacy data may be video data, picture data, text data, communication mode data, and other data related to the user.

Fig. 1 is a schematic structural diagram of an application system of a terminal control method according to an embodiment of the present invention, and as shown in fig. 1, the embodiment may include a terminal 101 and an image capture device 102 disposed in the terminal 101, where the image capture device 102 may be a camera for capturing a video, an image, or previewing, for example. In addition, a plurality of applications 103 related to the image capturing device may be deployed in the terminal 101, and data related to the applications 103 may be stored in the database 104. When a certain application 103 needs related data, the corresponding data may be acquired from the database 104, and the acquired data may be subjected to related processing. The terminal 101 may be a smart phone, a smart watch, a smart band, a tablet, or a personal computer, which can implement the above functions.
The technical solution of the present invention will be described in detail below with specific examples. The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments.
Fig. 2 is a flowchart illustrating a terminal control method according to an embodiment of the present invention, where the method according to this embodiment may be executed by the terminal 101. As shown in fig. 2, the method of this embodiment may include:
s201: and monitoring the state of the image acquisition equipment on the terminal in real time.
In this embodiment, two application scenarios may be involved, where one application scenario is to prevent the local multimedia data of the terminal from being stolen, and the other application scenario is to prevent the terminal from stealing the scene data corresponding to the external environment due to the security requirements of the current environment and the field situation. For example, scenes with security requirements such as public security, law, prison and the like can all generate the requirement of anti-candid shooting. Since the two scenes involve shooting or previewing of images, videos and the like, the image acquisition equipment for shooting or previewing the images needs to be monitored to monitor the state of the image acquisition equipment.
Further, the image capturing device may include two states, one being an on state and the other being an off state. If the image acquisition equipment is in an open state, the shooting or previewing of images, videos and the like can be realized. If the image acquisition equipment is in the closed state, it indicates that shooting or previewing of images, videos and the like cannot be realized in the current state.
S202: and when the image acquisition equipment is monitored to be in an open state, acquiring the running application program to obtain an application program set.
In this embodiment, when it is monitored that the image capture device is in the on state, it is indicated that there may be a risk of data leakage, and therefore, the operating state of each application program may be further determined, and it may be further determined whether there is a risk of data leakage.
The running state of the application program may include a running state and a non-running state, and when it is determined whether the application program is at risk of data leakage, the application program in the running state is determined, so as to obtain the application program set. For example, the terminal is deployed with an application a, an application B, an application C, an application D, an application E, and an application F, where the application a, the application B, and the application E are in an operating state, and the application C, the application D, and the application F are in a non-operating state, the application set may include three applications, namely, the application a, the application B, and the application E.
S203: and judging whether each application program in the application program set has the authority of starting the image acquisition equipment.
In this embodiment, each application has specific setting information, and the setting information may include information notification permission, permission to turn on the image capture device, permission to turn on the microphone, and the like.
Before determining whether each application in the application set has the authority to start the image acquisition device, setting information of each application may also be set, which may specifically include:
and receiving the setting information of each application program, wherein the setting information carries the authority information of the image acquisition equipment. And setting each application program based on the authority information of the image acquisition equipment corresponding to each application program.
Specifically, the permission information of the image acquisition device corresponding to the application program may include two conditions of permission and no permission, and the specific setting condition may be set for each application program in a user-defined manner according to requirements in an actual application scene, which is not limited in detail again.
S204: and if at least one target application program does not have the authority of starting the image acquisition equipment, emptying the multimedia data acquired by the image acquisition equipment.
In this embodiment, after determining the authority information of the image capturing device corresponding to each application program, if an application program without the authority to start the image capturing device is running, in order to avoid a situation of multimedia data leakage, the multimedia data captured by the image capturing device may be directly emptied.
In addition, if the multimedia data acquired by the image acquisition device are all subjected to emptying processing, the application program which needs the multimedia data may not receive the corresponding application program, and in order to further improve the use experience of a user, when at least one target application program does not have the right to start the image acquisition device, only the multimedia data to be sent to the target application program is subjected to emptying processing.
Specifically, the foregoing example is continuously used, the application set includes three application programs, namely, the application program a, the application program B, and the application program E, which are in a running state, and only the application program E does not have the authority to start the image capture device, so that only the multimedia data to be sent to the application program E can be emptied.
Further, if there is at least one target application program that does not have the authority to start the image capturing device, performing emptying processing on the multimedia data captured by the image capturing device, which may specifically include:
and if at least one target application program does not have the authority of starting the image acquisition equipment, performing zero setting operation on the photographing stream data and/or the preview stream data to be written into the buffer space.
Specifically, the multimedia data may be different in kind, and may include only photograph-stream data, or only preview-stream data, or may include both photograph-stream data and preview-stream data. For different application scenarios, different kinds of multimedia data may be employed.
For example, for a scene involving only a photograph or a video recording, multimedia data including only photograph stream data may be applied. For scenes that involve only previews, multimedia data that include only preview stream data may be applied. And for scenes involving both photographing or video recording and previewing, multimedia data including both photographing stream data and preview stream data may be applied.
In addition, for the specific situation that the application scene is not clear or the application scene itself may change at any time, the multimedia data including the photo stream data and the preview stream data can be used for emptying, so that the possibility that the privacy data is stolen is reduced, and the reliability of privacy data protection is improved.
In addition, in a general case, the terminal may store the photo stream data and/or the video stream data into the buffer space after acquiring the photo stream data and/or the video stream data, and may directly call the photo stream data and/or the video stream data from the buffer space when calling the photo stream data and/or the video stream data. In this embodiment, when it is monitored that at least one running application program does not have the right to open the image capturing device, the photo stream data and/or the video stream data to be written into the cache space may be set to zero, thereby reducing the possibility of data theft.
After the scheme is adopted, the state of the image acquisition equipment on the terminal can be monitored in real time, then when the image acquisition equipment is monitored to be in the opening state, the running application program is obtained, the application program set is obtained, whether each application program in the application program set has the authority to open the image acquisition equipment or not is judged, if at least one target application program does not have the authority to open the image acquisition equipment, the multimedia data acquired by the image acquisition equipment is emptied, additional hardware equipment does not need to be added, and further the native implementation logic does not need to be changed according to newly added hardware equipment, so that the implementation mode of user privacy data protection is simplified, and further the reliability of privacy data protection is improved.
Based on the method of fig. 2, the present specification also provides some specific embodiments of the method, which are described below.
Fig. 3 is a schematic flowchart of a terminal control method according to another embodiment of the present invention, as shown in fig. 3, before S201, the method may further include:
s301: and receiving a monitoring starting instruction.
S302: and starting the monitoring function according to the monitoring starting instruction.
In this embodiment, before monitoring the state of the image capturing device, the monitoring function may be started first, and then the state of the image capturing device on the terminal may be monitored in real time. The monitoring function can be started by receiving the monitoring starting instruction and then according to the monitoring starting instruction.
Further, receiving the monitoring start instruction may include two ways, one of which is receiving the monitoring start instruction sent by the server. And the other is to receive a monitoring starting instruction sent by a local three-party application program.
Specifically, for scenes in which the current environment and field conditions need to be kept secret, for example, scenes in which security needs exist such as polices, judicial officers, prisons and the like, the monitoring starting instruction sent by the server can be received. Correspondingly, the server can simultaneously send a monitoring start instruction to one or more terminals. For scenes with security requirements such as public security, judicial law, prisons and the like, the server can send monitoring starting instructions to terminals within a preset range with the scenes as centers, and the terminals need to actively start a monitoring function after receiving the monitoring starting instructions, so that the current environment and field conditions are prevented from being leaked. Whether the terminal is in the preset range can be determined through a locator carried by the terminal, and correspondingly, the terminal can communicate in a wireless communication mode, a Bluetooth communication mode or communication modes such as 3G, 4G and 5G.
For a scene for preventing the local multimedia data of the terminal from being stolen, a monitoring starting instruction sent by a local three-party application program can be received. Correspondingly, an application program or a script and the like for stealing data may exist locally on the terminal, the state of the image acquisition equipment can be monitored through the three-party application program locally deployed on the terminal, and then the processing is correspondingly carried out according to the state of the image acquisition equipment, so that the situation that the local data is stolen is reduced.
In addition, fig. 4 is an application schematic diagram of the clearing processing prompt provided by the embodiment of the present invention, and the terminal may further include a display interface, as shown in fig. 4, after S204, the terminal may further include:
and generating a clearing processing prompt.
And displaying a clearing processing prompt on a terminal interface.
Specifically, after the multimedia data collected by the image collecting device is emptied, an emptying processing prompt may be displayed on a display interface of the terminal to remind a user that the collected multimedia data has been emptied to avoid data leakage. Illustratively, the flush processing prompt may be "multimedia data has been flushed! ! | A "is indicated by a text typeface.
In addition, the emptying process prompt may also be a voice prompt.
In addition, fig. 5 is an application schematic diagram of the terminal control method according to an embodiment of the present invention, as shown in fig. 5, in this embodiment, the method is applied to an Android system, and multimedia data includes Image data such as photograph stream data and preview stream data, and with the development of the Android system, functions such as photograph and video recording can be implemented without a preview, an ISP (Image Signal Processor) can send the multimedia data acquired by an Image acquisition device to a HAL Layer (Hardware Abstraction Layer), after receiving the multimedia data, a HAL Layer can directly perform zeroing processing on the preview stream data and the photograph stream data that flow into a cache space, that is, when a monitoring function is turned on, the monitoring function starts to monitor a current camera state, finds that the data stream is created to enable a function to take effect, directly writes 0 to a buffer of the photograph data, and exits from the monitoring after the monitoring is turned off, and a normal flow is recovered, and after the monitoring function is turned on, scenes related to the Image data can be included, so as to avoid omission, and further achieve reliability of protecting the privacy data.
