Embodiment one

An embodiment of the present invention provides a method for controlling a terminal. Please refer to FIG. 1 , which is a schematic flowchart of Embodiment 1 of a method for controlling a terminal provided in an embodiment of the present invention. As shown in the figure, the method includes the following steps:

S101. When the terminal is in an unlocked state, detect the state of the terminal's front host user.

S102, if it is detected that the status of the owner user in front of the terminal is that the owner user leaves the terminal, perform a locking operation on the terminal.

For example, in the embodiment of the present invention, when the terminal is in an unlocked state, the method for detecting the state of the previous owner user of the terminal may include but not limited to:

First, when the terminal is in an unlocked state, the distance data between the terminal and the previous owner user of the terminal is detected. Then, according to the distance data, the status of the owner user of the terminal is detected.

In a specific implementation process, the distance detection module may be used to detect the distance data between the terminal and the previous owner user of the terminal. For example, the distance detection module may be a distance sensor. The distance detection module may be located inside the terminal, or may be located outside the terminal, which is not particularly limited in this embodiment of the present invention. For example, as shown in FIG. 2 , the distance detection module may be located above the terminal as a peripheral device of the terminal.

For example, in the embodiment of the present invention, according to the distance data, the method for detecting the state of the user of the previous terminal may include but not limited to:

First, if the distance between the terminal and the main user in front of the terminal does not exceed the detection distance of the distance detection module, the distance data detected by the distance detection module is the distance between the terminal and the main user in front of the terminal. distance between values. Furthermore, the detected distance data may be compared with a preset distance threshold. If the distance data is greater than or equal to the preset distance threshold, it means that the owner user has moved far away from the terminal, and in order to further determine that the owner user has moved far away from the terminal, continue to collect images in front of the terminal. On the contrary, if the distance data is less than the distance threshold, it means that the owner user has not left the terminal for a relatively long distance, and the status of the owner user before the terminal is determined as the owner user has not left the terminal.

Or, if the distance between the terminal and the previous owner user of the terminal exceeds the detection distance of the distance detection module, the distance data detected by the distance detection module is an indication signal that can indicate that the detection distance is exceeded. Furthermore, if the distance data of the terminal is an indication signal exceeding the detection distance, it means that the owner user has left the terminal far away, so that the distance detection module cannot detect the distance between the terminal and the owner user. In order to further determine that the owner and user have left the terminal far away, continue to collect images in front of the terminal.

Then, if the image in front of the terminal is collected, the status of the owner user in front of the terminal is detected according to the image in front of the terminal.

In a specific implementation process, the image in front of the terminal can be collected by using the image collection module. For example, the image acquisition module may be a camera. Wherein, the image acquisition module may be located in the terminal, or may be located outside the terminal, which is not particularly limited in this embodiment of the present invention. For example, as shown in FIG. 2, the image acquisition module may be located above the terminal and serve as a peripheral device of the terminal.

For example, in the embodiment of the present invention, the method for detecting the status of the owner user of the front terminal according to the image in front of the terminal may include but not limited to:

Face recognition processing is performed on the image in front of the terminal. If the image of the owner user is not recognized from the image in front of the terminal, determine that the state of the owner user in front of the terminal is that the owner user leaves the terminal. Conversely, if the image of the owner user is recognized from the image in front of the terminal, it is determined that the owner user in front of the terminal has not left the terminal.

In a specific implementation process, a face recognition algorithm may be used to perform face recognition processing on the image in front of the terminal.

In a specific implementation process, the terminal may send the collected image in front of the terminal to the server through the network, so that the server uses a face recognition algorithm to perform face recognition processing on the image in front of the terminal, and The face recognition result is returned to the terminal, and the terminal detects the state of the terminal's front owner user according to the face recognition result. Alternatively, the terminal may use a face recognition algorithm to perform face recognition processing on the image in front of the terminal, obtain a face recognition result, and detect the status of the main user of the terminal front according to the face recognition result.

For example, the method of performing face recognition processing on the image in front of the terminal using a face recognition algorithm may include but not limited to:

Face image detection is performed on the image in front of the terminal to obtain the position and size of the face in the image in front of the terminal. If the position and size of the human face in the pre-terminal image are successfully acquired, preprocessing may continue to be performed on the pre-terminal image according to the position and size of the human face in the pre-terminal image. Conversely, if the position and size of the human face in the image in front of the terminal cannot be obtained, it is considered that the image of the owner user has not been recognized from the image in front of the terminal. Then, based on the face image detection result, the face image is preprocessed, and the preprocessing may include light compensation, grayscale transformation, histogram equalization, normalization, geometric correction, filtering, and sharpening. Face feature extraction is performed on the preprocessed face image to extract features such as visual features, pixel statistical features, face image transformation coefficient features, and face image algebraic features from the face image. Finally, match the extracted facial features with the pre-stored feature template of the owner user, and if the similarity between the two is greater than or equal to the preset similarity threshold, it is considered that the machine is identified from the image in front of the terminal. The image of the main user determines that the status of the main user in front of the terminal is that the main user has not left the terminal. Or, if the similarity between the two is less than or the similarity threshold, it is considered that the image of the owner user is not recognized from the image in front of the terminal, and the state of the owner user in front of the terminal is determined as the owner user leaving terminal.

In a specific implementation process, if it is detected that the status of the owner user before the terminal is that the owner user has left the terminal, a locking operation is performed on the terminal. In this way, after detecting that the owner user has left the terminal, the terminal is automatically locked, which can prevent other users from using the terminal of the owner user, thereby preventing the owner user from maliciously stealing important personal information and important work information. , improve the security and reliability of the terminal, and the automatic locking operation can reduce the cost of the terminal locking operation and improve the locking efficiency.

In a specific implementation process, if it is detected that the status of the owner user of the terminal is that the owner user has not left the terminal, no locking operation is performed on the terminal, and the unlocked state of the terminal is maintained.

In a specific implementation process, after the terminal is locked, the image acquisition module may be controlled to enter a standby power-saving mode. It is also possible to control at least one of the distance detection module and the vibration detection module to maintain the monitoring state of the terminal. In this way, when the terminal is in the locked state, at least one of the distance detection module and the vibration detection module monitors the terminal.

It should be noted that the terminals involved in the embodiments of the present invention may include but not limited to personal computers (Personal Computer, PC), personal digital assistants (Personal Digital Assistant, PDA), wireless handheld devices, tablet computers (Tablet Computer), cell phone etc.

It should be noted that the execution subject of S101-S103 may be the control system of the terminal, and the control system of the terminal may be located in the terminal, or part of it may be located in the terminal, and the rest is located in the peripheral device of the terminal. Examples do not specifically limit this.

Embodiment two

An embodiment of the present invention provides a method for controlling a terminal. Please refer to FIG. 3 , which is a schematic flowchart of Embodiment 2 of a method for controlling a terminal provided in an embodiment of the present invention. As shown in the figure, the method includes the following steps:

S301. When the terminal is in a locked state, collect an image of the current user of the terminal.

S302. Determine whether the current terminal user is an owner user according to the image of the current terminal user.

S303. If the current user of the terminal is the owner user, release the locked state of the terminal.

It should be noted that the terminal control method provided by the embodiment of the present invention is essentially a method for unlocking the terminal when the terminal is in a locked state. It can be understood that the unlocking method can be based on the terminal locking method described in the terminal control method provided in the first embodiment above, or the unlocking method can also be based on the method of manually locking the terminal by the user. This is not particularly limited.

For example, in the embodiment of the present invention, when the terminal is locked, the method for collecting the image of the current user of the terminal may include but not limited to:

First, when the terminal is in a locked state, it is detected whether there is a user in front of the terminal and/or whether the terminal vibrates, so as to obtain a detection result. Then, if the detection result includes at least one of detection of a user in front of the terminal and detection of vibration of the terminal, an image of the current user of the terminal is collected.

Based on what is mentioned in the terminal control method provided in Embodiment 1, when the terminal is in the locked state, at least one of the distance detection module and the vibration detection module maintains the monitoring state of the terminal, therefore, the distance detection can be used The module detects whether there is a user in front of the terminal. If the distance between the current user of the terminal and the terminal is within the detection range of the distance detection module, the distance detection module can detect the distance between the current user of the terminal and the terminal. If the distance data is less than the preset distance threshold, it is considered that there is a user in front of the terminal. On the contrary, if the distance data is greater than or equal to the preset distance threshold, it is considered that there is no user in front of the terminal.

In addition, the vibration detection module can be used to detect whether the terminal vibrates, and if the terminal is damaged by other users or the vibration detection module is damaged by other users, the vibration detection module can detect the vibration parameters of the terminal , if the vibration parameter is greater than or equal to the preset vibration threshold, it means that the vibration of the terminal exceeds the normal level, and the terminal is considered to be vibrating; otherwise, if the vibration parameter is less than the preset vibration threshold, it means that the vibration of the terminal is normal If the terminal shakes slightly, it is considered that the terminal does not vibrate.

In a specific implementation process, the vibration detection module may be a vibration sensor. The vibration detection module may be located inside the terminal, or may also be located outside the terminal, which is not particularly limited in this embodiment of the present invention. For example, as shown in FIG. 2 , the vibration detection module may be located above the terminal as a peripheral device of the terminal.

In a specific implementation process, if there is at least one of detecting that there is a user in front of the terminal and detecting that the terminal is vibrating, the image acquisition module is triggered, and the triggered image acquisition module enters from the previous standby power-saving mode working mode, and collect images of the current user of the terminal.

For example, in the embodiment of the present invention, according to the image of the current user of the terminal, the method for judging whether the current user of the terminal is the owner user may include but not limited to:

First, face recognition processing is performed on the image of the current user of the terminal by using a face recognition algorithm to obtain a face recognition processing result. Then, according to the face recognition processing result, it is judged whether the current user of the terminal is the owner user.

It should be noted that, the method of performing face recognition processing on the image of the current user of the terminal by using the face recognition algorithm can refer to the method of performing face recognition processing on the image in front of the terminal by using the face recognition algorithm described in Embodiment 1. method, which will not be repeated here.

In a specific implementation process, if the result of the face recognition processing is that the similarity between the face features of the user in front of the terminal and the pre-stored feature template of the owner user is greater than or equal to a preset similarity threshold, it is determined that If the current user of the terminal is the owner user; on the contrary, if the face recognition processing result shows that the similarity between the facial features of the front user of the terminal and the pre-stored feature template of the owner user is less than the similarity threshold, Then it is determined that the current user of the terminal is not the owner user.

In a specific implementation process, if the current user of the terminal is not the owner user, the locked state of the terminal is maintained and the locked state of the terminal is not released, so as to prevent the current user of the terminal from using the owner The user's terminal, thereby avoiding malicious theft of important personal information and important work information of the owner and user, and improving terminal security and reliability.

In a specific implementation process, if the current user of the terminal is not the owner user, at least one of the following operations may also be performed:

saving the image of the current user of the terminal in the terminal;

uploading the image of the current user of the terminal to the server;

collecting video data of the current user of the terminal, and sending the video data or the video data and an image of the current user of the terminal to the owner user of the terminal; and,

Sending alarm prompt information to the owner user of the terminal.

It can be understood that saving the image of the current user of the terminal in the terminal can make it easier for the owner user of the terminal to know that other users have illegally operated the terminal before and after returning to the terminal, and obtain the information of the current user. Appropriate measures.

It can be understood that uploading the image of the current user of the terminal to the server can facilitate the owner user to know that other users illegally operate the terminal. And when the owner user cannot return to the terminal in time, the owner user can log in to the server through other terminals to obtain the current user's information, and take corresponding measures.

In a specific implementation process, if it is determined that the current user of the terminal is not the owner user, the image collection module may be used to collect video data of the current user of the terminal, and then the video data or the video data and the image of the current user of the terminal are sent to the owner user of the terminal; so that the owner user of the terminal can know that other users illegally operate the terminal, the owner user can obtain the information of the current user in time, and take corresponding measures measures.

Or, it is also possible to send an alarm message to the owner user of the terminal through a short message, so that the owner user of the terminal can know that there are other users illegally operating the terminal, and the owner user can obtain the information of the current user in time, and take actions Appropriate measures.

In a specific implementation process, if the current user of the terminal is the owner user, the face recognition algorithm may also be updated according to the image of the current user of the terminal.

For example, if the execution body that uses the face recognition algorithm to perform face recognition on the image of the current user of the terminal is located on the server side, then if the current user of the terminal is the owner user, the image collection module needs to collect The image of the current user of the terminal is sent to the server, so that the server can update the local face recognition algorithm according to the image of the current user of the terminal, thereby improving the efficiency and accuracy of face recognition.

Or, for another example, if the body performing face recognition on the image of the current user of the terminal by using the face recognition algorithm is located in the terminal, and the image acquisition module is located outside the terminal, then the current user of the terminal is the In the case of the main user, the image collection module needs to send the collected image of the current user of the terminal to the terminal, so that the terminal can update the local face recognition algorithm according to the image of the current user of the terminal, thereby improving Efficiency and accuracy of face recognition.

It should be noted that the execution subject of S301-S303 may be the control system of the terminal, and the control system of the terminal may be located in the terminal, or part of it may be located in the terminal, and the rest is located in the peripheral device of the terminal. Examples do not specifically limit this.
