detailed description

In order to make the purposes, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments These are some embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terms used herein in the description of the present invention are for the purpose of describing specific embodiments only, and are not intended to limit the present invention.

In order to facilitate the understanding of the technical solutions in this embodiment, the following related solutions are described:

In the process of using the terminal device, the terminal device may be exposed to public places. At this time, the content presented by its screen or other presentation interfaces (such as speakers, High Definition Multimedia Interface, HDMI for short) is relatively easy It is acquired intentionally or unintentionally by surrounding personnel, so that the data information located in the terminal device is easily leaked, which reduces the user experience.

In view of the above situation, the related art proposes different privacy protection methods. The current privacy protection methods usually include the following:

(1) The method of direct anti-peep film, that is, using the anti-peep film to control the visible range, so as to restrict the information displayed on the terminal device from being acquired by the outside world. Under normal circumstances, the privacy film will reduce the display brightness of the interface, which will reduce the user's good experience, especially for some application scenarios that require a large-scale display of content, it is inconvenient to quickly install and remove the privacy film dynamically. Therefore, the leakage of data information cannot be avoided in a timely and effective manner.

(2) Dynamic privacy film mode, that is, it can be dynamically switched between privacy protection mode or ordinary wide area mode. However, the switching operation is generally performed by the user actively through the button, which lacks intelligence and automation, and is prone to leakage of data and information due to the negligence of the user. In addition, the control strategy for the terminal device is controlled by the user. Therefore, for the terminal device, it is impossible to prevent the user from actively and deliberately leaking information. For example, for some important relevant information, in principle, it cannot be leaked, but the user actively pushes The device switches to the normal wide area mode, so that other users can view relevant information through the terminal device in the normal wide area mode.

In order to solve the above technical problems, the present embodiment provides a control method, device and storage medium for a terminal device, wherein the control method obtains interface information displayed on the terminal device, and then performs the interface information and the user in front of the display interface. Analysis and identification, when the result of analysis and identification is that the interface information meets the preset control conditions and the user is a legal identity, the visual range used to display the interface information can be adjusted, thereby effectively realizing the detection of the interface information displayed on the terminal device. The interface information and the user located in front of the terminal device are analyzed and identified, and then the visual range used to display the interface information is dynamically adjusted based on the analysis and identification results, so as to reduce the leakage probability of the interface information. The situation can be effectively controlled and supervised, thereby ensuring a good user experience and improving the practicability of the method.

Some embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The following embodiments and features in the embodiments may be combined with each other without conflict between the embodiments.

FIG. 1 is a schematic flowchart of a method for controlling a terminal device according to an embodiment of the present invention; with reference to FIG. 1 , this embodiment provides a method for controlling a terminal device, where the terminal device may include any one of the following : mobile phone, tablet computer, notebook computer, personal computer PC, etc. The execution body of the method can be the control device of the terminal device. It can be understood that the control device of the terminal device can be implemented as software or a combination of software and hardware . Specifically, the control method of the terminal device may include:

Step S101: Obtain interface information displayed on the terminal device.

Step S102: Identify the identity type of the user to be identified located in front of the display interface of the terminal device.

Step S103 : when the interface information satisfies the preset condition and the identity type of the user to be identified is a legal identity, adjust the visible range for displaying the interface information to reduce the leakage probability of the interface information.

The above steps are described in detail below:

Step S101: Obtain interface information displayed on the terminal device.

The terminal device may refer to a terminal device including a display interface to display relevant interface information through the display interface. For example, a display screen is set on the terminal device, and the display screen is used to display the interface information, and the interface information It may include at least one of the following: instant messaging information, application program information, file information, picture information, and web page information. Of course, the interface information is not limited to the information content listed above. In other implementation manners, the information types included in the interface information may be arbitrarily set according to specific application scenarios and application requirements, which will not be repeated here.

In addition, this embodiment does not limit the specific acquisition manner of the interface information. In other embodiments, settings can be made according to specific application requirements and design requirements. For example, screen object attributes related to interface information are stored on the terminal device, and interface information displayed by the terminal device can be obtained by acquiring the screen object attributes. . Alternatively, the terminal device may be provided with a near field communication module (Near Field Communication, NFC for short), the NFC module is used to communicate and connect with an external NFC device, and can obtain information containing interface information from the external NFC device. NFC signal, and then the interface information displayed on the terminal device can be obtained through the NFC signal.

Of course, other methods may also be used to acquire the interface information displayed on the terminal device, as long as the accuracy and reliability of acquiring the interface information displayed on the terminal device can be ensured, which will not be repeated here.

Step S102: Identify the identity type of the user to be identified located in front of the display interface of the terminal device.

Wherein, the identity type of the user to be identified may include: legal identity and illegal identity. When applying to a terminal device, in order to prevent the data information displayed on the terminal device from being viewed or snooped by other illegal users, the identity types of all users to be identified located in front of the display interface of the terminal device can be identified. Specifically, the terminal device may be provided with an image acquisition module, and the image acquisition module may perform image acquisition operations on all users to be identified located in front of the display interface of the terminal device, so as to obtain user images corresponding to all users to be identified , and then the identity type of the user to be identified can be determined based on the user image.

It can be understood that the number of users to be identified located in front of the display interface of the terminal device may be one or more, and when the number of users to be identified is one, the determined identity type of the user to be identified may be legal or illegal. identity. When there are multiple users to be identified, the determined identity types of the users to be identified may include: legal identities and/or illegal identities.

In addition, the execution order between the above-mentioned steps S102 and S101 in this embodiment is not limited to the execution order defined in the above-mentioned embodiment, and those skilled in the art can analyze the steps S102 and S101 according to specific application requirements and design requirements. The execution sequence between them can be adjusted, for example, step S102 may be executed before step S101, or step S102 and step S101 may be executed simultaneously.

Step S103 : when the interface information satisfies the preset condition and the identity type of the user to be identified is a legal identity, adjust the visible range for displaying the interface information. By adjusting the visible range of interface information, the leakage probability of interface information can be reduced.

After the interface information is acquired, the interface information may be analyzed and processed to determine whether the interface information satisfies a preset condition, where the preset condition is a preconfigured information type condition for controlling the display interface of the terminal device. It should be noted that the number of users to be identified may be one or more. When the number of users to be identified is multiple, when identifying the identity type of the user to be identified, if the identity type of the user to be identified is a legal identity, Then it means that the result of analyzing and identifying all the identity types of the users to be identified is that all the users to be identified are legal identities; if the identity types of the users to be identified include illegal identities, it means that the identities of all users to be identified are identified The result of analyzing and identifying the type is that among all the users to be identified, at least one user to be identified has an illegal identity.

When the result of analyzing and processing the interface information and the user to be identified is that the interface information satisfies the preset conditions and the identity type of the user to be identified is a legal identity, it means that the interface information displayed on the display interface of the terminal device is more important, and The identity type of the user to be identified is a legal identity. At this time, by adjusting the visual range used to display interface information, the interface information displayed by the terminal device can be effectively ensured on the premise of allowing legitimate users to see the interface information. , which can avoid information leakage or reduce the risk of information leakage. Wherein, adjusting the visual range for displaying interface information may include at least one of the following: reducing the visual range for displaying interface information; and reducing the resolution of the visual range for displaying interface information. Of course, other methods can also be used to adjust the visible range used for displaying interface information, as long as the effect of reducing the leakage probability of interface information can be achieved, which will not be repeated here.

In some instances, the method in this embodiment may further include:

Step S104 : when the interface information does not meet the preset condition, the visual range for displaying the interface information is controlled to remain unchanged.

When the result of analyzing and processing the interface information is that the interface information does not meet the preset conditions, it means that the interface information displayed on the display interface of the terminal device is not very important. At this time, regardless of whether the identity type of the user to be identified includes illegal identity, it is not necessary to control the display interface of the terminal device, that is, the visual range for displaying interface information can be controlled to remain unchanged.

In some instances, the method in this embodiment may further include:

Step S105 : when the interface information satisfies the preset condition and the identity type of the user to be identified includes an illegal identity, close or minimize the display interface of the terminal device.

When the result of analyzing and processing the interface information and the user to be identified is that the interface information satisfies the preset conditions and the identity type of the user to be identified includes an illegal identity, it means that the interface information displayed on the display interface of the terminal device is relatively important, At this time, the users to be identified in front of the display interface of the terminal device include users with illegal identities. At this time, in order to avoid information leakage or reduce the risk of information leakage, the display interface of the terminal device can be closed or minimized.

In order to facilitate the understanding of the above technical solutions, the following description takes a notebook computer with a front camera and a display interface as a terminal device as an example:

Application Scenario 1, as shown in FIG. 2 , image information is displayed on the display interface of the notebook computer, and the to-be-identified users located in front of the display interface of the notebook computer include user A and user B. In order to avoid the leakage of data information, you can Analyze and identify the image information displayed on the display interface of the notebook computer, and perform an identity type identification operation on the user to be identified located in front of the display interface of the notebook computer, and the image information displayed on the display interface satisfies the preset conditions, And when both user A and user B are legal identities, the visible range of the display interface information can be adjusted according to the above identification results, for example, reducing the visible range of image information, or reducing the resolution of displaying image information.

Application scenario 2, as shown in FIG. 3 , image information is displayed on the display interface of the notebook computer, and the to-be-identified users located in front of the display interface of the notebook computer include user A and user B. In order to avoid leakage of data information, you can Analyze and identify the image information displayed on the display interface of the notebook computer, and perform an identity type identification operation on the user to be identified located in front of the display interface of the notebook computer, and the image information displayed on the display interface satisfies the preset conditions, And when user A is a legal identity and user B is an illegal identity, the display interface of the terminal device can be closed or minimized according to the above identification result.

Application scenario 3, as shown in FIG. 4 , image information is displayed on the display interface of the notebook computer, and the to-be-identified users located in front of the display interface of the notebook computer include user A and user B. In order to avoid the leakage of data information, you can Analyze and identify the image information displayed on the display interface of the notebook computer, and identify the identity type of the user to be identified located in front of the display interface of the notebook computer. The image information displayed on the display interface does not meet the preset conditions At this time, regardless of whether the identities of user A and user B are legal, the visual range used to display interface information remains unchanged.

The method for controlling a terminal device provided by this embodiment acquires interface information displayed on the terminal device, and then analyzes and identifies the interface information and the user located in front of the display interface. And when the user is a legal identity, the visual range for displaying interface information can be adjusted, thereby effectively realizing the interface information displayed on the terminal device and the user located in front of the terminal device through analysis and identification, and then based on the analysis and identification. As a result, the visual range for displaying interface information is dynamically adjusted to reduce the leakage probability of interface information, that is, it can effectively prevent irrelevant personnel from accessing and snooping on interface information. Effective control and supervision can be performed, thereby ensuring a good user experience and improving the practicability of the method.

FIG. 5 is a schematic flowchart of another method for controlling a terminal device according to an embodiment of the present invention; on the basis of the above embodiment, with continued reference to FIG. 5 , after it is determined that the identity type of the user to be identified includes an illegal identity , the method in this embodiment may also include:

Step S501: Obtain distance information between the user to be identified and the terminal device.

Step S502: Adjust the visible range for displaying interface information according to the distance information.

In order to accurately control the terminal device, when it is detected that there are one or more to-be-identified users at the front end of the display interface of the terminal device, the distance information between the to-be-identified user and the terminal device can be obtained, wherein the distance information is obtained. Implementations may include: acquiring a depth image including the user to be identified, and determining distance information between the user to be identified and the terminal device through the depth image.

After obtaining the distance information between the user to be identified and the terminal device, the distance information can be analyzed and processed to adjust the visible range of the user display interface information according to the analysis and processing result of the distance information. Specifically, according to the distance information, adjusting the visible range for displaying interface information may include:

Step S5021: when the distance information is greater than or equal to the preset distance threshold, reduce the resolution of the visual range used to display the interface information; or,

Step S5022: when the distance information is less than the preset distance threshold, close or minimize the display interface of the terminal device.

Wherein, a preset distance threshold for analyzing and processing the distance information is preconfigured, and the preset distance threshold is used to identify a distance limit value at which the distance between the user and the terminal device is relatively close. After the distance information is obtained, the distance information can be analyzed and compared with the preset distance threshold. When the distance information is greater than or equal to the preset distance threshold, it means that the distance between the user and the terminal device is relatively far. In this case, the user located in front of the terminal device cannot clearly know the information content displayed on the display interface on the terminal device. However, in order to reduce the leakage probability of interface information, the resolution of the visual range for displaying interface information can be reduced.

When the distance information is less than the preset distance threshold, it means that the distance between the user and the terminal device is relatively close. At this time, under normal circumstances, the user can clearly know the information content displayed on the display interface of the terminal device. Therefore, In order to reduce the leakage probability of interface information, the display interface of the terminal device may be closed or minimized.

In some instances, since the user located in the terminal device may change in real time, after reducing the resolution of the visual range for displaying interface information, the method in this embodiment may further include:

Step S503: When the identity type of the user to be identified changes to a legal identity, restore the resolution of the visual range used for displaying interface information.

For example, the preset distance threshold may be 3m, and the users located at the front end of the display interface of the terminal device include user A. When user A is an illegal identity, it means that the identity of the user to be identified is located in front of the display interface of the terminal device at this time. If the type includes illegal identity, the distance information between user A and the terminal device can be obtained. When the distance information is greater than 3m, the resolution of the visual range used to display the interface information can be reduced. When the distance information is less than or equal to 3m , the display interface of the terminal device can be closed or minimized.

When the user at the front of the display interface of the terminal device changes from user A to user B, and user B is a legal identity, it means that the user to be identified at the front of the display interface of the terminal device has changed from an illegal user to a legal user. When the resolution is displayed, the resolution of the visual range used for displaying the interface information can be restored, so that the legitimate user can clearly see the interface information located on the terminal device.

In some instances, in order to avoid operations such as false triggering of the display interface, after minimizing the display interface of the terminal device, the method in this embodiment may further include:

Step S504: Lock the current state of the display interface.

If the method of adjusting the display interface of the terminal device is to minimize the display interface of the terminal device, after the display interface of the terminal device is minimized, in order to avoid the occurrence of illegal identities, the user can view the displayed information on the terminal device by performing operations on the terminal device. The current state of the display interface can be locked, even if the user with an illegal identity cannot view the interface information displayed on the terminal device by performing operations on the terminal device, which further ensures the security of the display of the interface information. .

In other instances, after locking the current state of the display interface, the method in this embodiment may further include:

Step S505: when the identity type of the user to be identified is converted into a legal identity, unlock the locked state of the display interface.

For example, when user A located in front of the terminal device is changed to user B, and user B is a legal identity, that is, the identity type of the user to be identified is changed to a legal identity. At this time, in order to enable the legal identity user B to When viewing or other editing operations on the interface information on the terminal device, the locked state of the display interface can be unlocked, which not only ensures the security of the display of interface information, but also enables legitimate users to perform operations on the interface information. View and edit operations, thereby increasing the flexibility and reliability of the use of terminal devices.

FIG. 6 is a schematic flowchart of another method for controlling a terminal device provided by an embodiment of the present invention; on the basis of the above embodiment, with continued reference to FIG. 6 , after it is determined that the identity type of the user to be identified includes an illegal identity , the method in this embodiment may also include:

Step S601: Obtain the gesture information of the user to be recognized.

Step S602: when the posture information is facing the display interface of the terminal device, close or minimize the display interface of the terminal device. or,

Step S603 : when the gesture information is not facing the display interface of the terminal device, adjust the visible range for displaying the interface information, so as to reduce the leakage probability of the interface information.

After it is determined that the identity types of the users to be identified include illegal identities, users with illegal identities may have different postures, and the different postures of the users may affect whether the user can view the interface content displayed on the terminal device. Therefore, in order to improve the accuracy and reliability of controlling the terminal device, the gesture information of the user to be recognized may be acquired; in some instances, acquiring the gesture information of the user to be recognized includes: acquiring the gesture information of the illegal identity user to be recognized. For example, the users to be identified may include user A, user B, and user C. Among them, user A and user C are illegal identities, and user B is a legal identity. Then, when obtaining the gesture information of the user to be identified, it is only necessary to obtain The posture information of user A and user C is not required to obtain the posture information of user B.

In addition, this embodiment does not limit the specific implementation of acquiring the gesture information of the user to be recognized, and those skilled in the art can set according to specific application requirements and design requirements. For example, the face of the user to be recognized can be acquired through an image acquisition module. information, determine the posture information of the user to be recognized through facial information, when the acquired facial information of the user to be recognized can include facial features (eyebrows, eyes, ears, nose, mouth), then the posture information of the user to be recognized can be determined as Facing the display interface of the terminal device, when the acquired facial information of the user to be recognized does not include all facial features, it can be determined that the facial information of the user to be recognized is not the display interface facing the terminal device, for example: the user to be recognized The display interface of the terminal device facing from the side, or the display interface of the user to be identified facing away from the terminal device, and so on.

In addition, when the posture information of the user to be identified is obtained as being facing the display interface of the terminal device, it means that the user to be identified at this time can clearly see the display interface of the terminal device. At this time, in order to reduce the display interface of the terminal device If the leakage probability of interface information is determined, the display interface of the terminal device can be closed or minimized. When the gesture information is not facing the display interface of the terminal device, it means that the user to be identified at this time cannot clearly see the display interface of the terminal device. At this time, in order to reduce the leakage probability of the interface information displayed on the terminal device, Then the visual range for displaying interface information can be adjusted (reduce the visual range for displaying interface information, and/or reduce the resolution of the visual range for displaying interface information) to reduce the leakage probability of interface information .

In this embodiment, by acquiring the posture information of the user to be identified, and then when the posture information is the display interface facing the terminal device, the display interface of the terminal device is closed or minimized; when the posture information is not the display interface facing the terminal device When the interface is displayed, the visual range for displaying interface information can be adjusted, which effectively realizes the judgment of whether the user to be identified who is located in front of the terminal device has the gesture information to view the interface information, and when the user can view the interface information , the display interface of the terminal device can be closed or minimized, and when the user cannot view the interface information, the visual range used to display the interface information can be adjusted, thereby effectively reducing the leakage probability of the interface information and further improving the accuracy of the interface information. Accurate and reliable control of terminal equipment.

FIG. 7 is a schematic flowchart of another method for controlling a terminal device according to an embodiment of the present invention; on the basis of the above embodiment, with continued reference to FIG. 7 , after acquiring interface information displayed on the terminal device, you can The interface information is analyzed and processed to identify whether the interface information meets a preset condition. Specifically, the method in this embodiment may further include:

Step S701: Determine the security level corresponding to the interface information.

Among them, because the interface information displayed by the terminal device can be a variety of information, and different interface information can correspond to different security levels, for example, the security level corresponding to the interface information can include the information used to identify the interface information is more important The first level is used to identify the interface information as general, the third level is used to identify that the interface information is not very important, and so on. Therefore, after acquiring the interface information, the interface information can be analyzed and processed to determine the security level corresponding to the interface information. Specifically, referring to FIG. 8 , determining the security level corresponding to the interface information may include:

Step S7011: Acquire information tags and/or information keywords corresponding to the interface information.

Step S7012: Determine the security level corresponding to the interface information based on the information tag and/or the information keyword.

After the interface information is obtained, a preset algorithm or a preset machine learning model can be used to analyze and process the interface information to obtain information labels and/or information keywords corresponding to the interface information. After the keyword, the security level corresponding to the interface information can be determined based on the information tag and/or the information keyword. Specifically, the mapping relationship between the information label and/or the information keyword and the security level is preset, and after the information label and/or the information keyword is acquired, the security level corresponding to the interface information can be determined based on the above-mentioned mapping relationship .

Step S702: When the security level is higher than the preset level, it is determined that the interface information satisfies the preset condition. or,

Step S703: When the security level is lower than or equal to the preset level, it is determined that the interface information does not meet the preset condition.

After the security level corresponding to the interface information is obtained, the security level can be analyzed and compared with the preset level. The preset level can be the lowest level used to identify the interface information that is more important. When the security level is higher than the preset level is determined, it can be determined that the interface information satisfies the preset condition, that is, the interface information displayed on the terminal device is relatively important. When the security level is lower than or equal to the preset level, it can be determined that the interface information does not meet the preset condition, that is, the interface information displayed on the terminal device is not very important.

In this embodiment, by determining the security level corresponding to the interface information, when the security level is higher than the preset level, it is determined that the interface information satisfies the preset condition, and when the security level is lower than or equal to the preset level, the interface is determined The information does not meet the preset conditions, thus effectively realizing the analysis and processing of the interface information displayed on the terminal device to identify whether the interface information meets the preset conditions, and further improving the stability of the terminal device control based on the identification result of the interface information. reliability.

Step S901: Acquire the facial features of the user to be identified.

Step S902: when the facial features of the user to be identified match the preset standard facial features, determine that the identity type of the user to be identified is a legal identity. or,

Step S903: when the facial features of the user to be identified do not match the preset standard facial features, determine that the identity type of the user to be identified is an illegal identity.

Wherein, preset standard facial features for identifying the user identity as legal identity are pre-configured, and the number of the preset standard facial features may be one or more. In order to effectively recognize the identity of the user to be recognized, the facial features of the user to be recognized can be obtained through the image acquisition module, and then the facial features of the user to be recognized can be analyzed and processed based on the preset standard facial features. The facial features of the user to be recognized are analyzed and matched with the preset standard facial features. When the facial features of the user to be recognized match the preset standard facial features, it can be determined that the identity type of the user to be recognized is a legal identity. When it does not match the preset standard facial features, it can be determined that the identity type of the user to be identified is an illegal identity.
