According to the embodiment of the invention, an anti-peeping protective film does not need to be adhered to the outer surface of the terminal screen, so that the outer surface of the screen cannot be damaged due to repeated replacement of the protective film and the cost of the additional protective film is saved.
In order to describe the above embodiment in more detail, an embodiment of the present invention further provides another screen adjusting method based on privacy protection, as shown in fig. 2, the method is that while the corresponding visual angle is automatically adjusted when the data information is displayed on the screen on the terminal, the number of faces above the outer surface of the screen can be identified by using a front-facing camera on the terminal according to a face identification technology, and whether there is someone peeping the data information displayed on the screen or not can be identified in time, and the following specific steps are provided for the embodiment of the present invention:
201a, obtaining scene parameters in the current application scene of the terminal.
The current application scene refers to different environments where a user is located when using the terminal, and the scene parameters refer to environment factor parameters under the different environments, such as a noise decibel value, a light brightness value, and the like.
In the embodiment of the invention, the purpose of acquiring the scene parameters in the current application scene of the terminal is to analyze the acquired scene parameters by using the large probability event and judge that the large probability event of the current scene of the terminal is a people flow dense area and a public place, so that the terminal can be controlled timely to effectively and timely perform privacy protection, and the data information displayed on the terminal is prevented from being peeped by others easily when a user refers to the data information on the terminal.
202a, judging whether a preset privacy mode is triggered to be started on the terminal or not according to the scene parameters.
In the embodiment of the present invention, the specific step of determining whether to trigger the opening of the preset privacy mode on the terminal according to the scene parameter may be as follows:
in an embodiment of the present invention, a method for determining whether to trigger the opening of a preset privacy mode on a terminal is: when the acquired scene parameter is the sound intensity value, judging whether the sound intensity value is larger than a preset threshold value, if so, judging that the current application scene of the terminal is a public place, and triggering and starting a preset privacy mode on the terminal.
The sound intensity value is a decibel value, the preset threshold value is used for measuring the sound decibel value in the current scene, whether the sound decibel value in the current scene is greater than the preset threshold value or not is measured, the current scene is judged to be a probable event of a public place, due to the fact that people flow in the public place is dense, the situation that data information displayed on a screen on a terminal is peeped by others is easy to happen, whether a preset privacy mode is triggered to be started or not is timely judged according to the sound intensity value in the current scene, and therefore the data information displayed on the screen of the terminal is effectively and timely prevented from being leaked.
In the embodiment of the present invention, another method for determining whether to trigger the opening of the preset privacy mode on the terminal is: when the acquired scene parameters are the light intensity values received by the screen on the terminal, judging whether the light intensity values are smaller than a preset threshold value, if so, judging that a shielding object exists above the surface of the screen on the terminal, and triggering and starting a preset privacy mode on the terminal.
The terminal screen receiving light intensity value is compared with a preset threshold value, so that the fact that a shielding object exists above the surface of the terminal screen is measured, namely, whether a large probability event that the terminal screen is shielded by other people exists is analyzed through the shielding object, and then whether a preset privacy mode needs to be triggered and started on the terminal is timely judged, and therefore the fact that the display data information of the terminal screen is leaked is effectively and timely avoided.
It should be noted that, the above is only an exemplary method for determining whether to trigger the opening of the preset privacy mode on the terminal according to the scene parameter in the embodiment of the present invention, and the embodiment of the present invention includes but is not limited to the above method, and details are not described herein again.

In the embodiment of the invention, the number of faces existing above the surface of the screen on the terminal can be identified by utilizing the front-facing camera on the terminal according to a face identification technology, before the identification, the faces of users corresponding to the terminal can be shot in advance, comparison is carried out according to the reference, when the identification is different from the preset faces, the existence of the peeping screen of other people is judged, or the number of the faces allowed to exist in the shooting range of the front-facing camera can be simply set, and when the number exceeds the number, the privacy protection is judged to be carried out, so that the display data information of the screen is prevented from being peeped by other people.
203b judges whether the number of the recognized faces is larger than a fifth preset threshold value.
In the embodiment of the invention, when the front-facing camera on the terminal is used for recognizing the face, whether the number of the faces existing in the corresponding shooting range of the camera is larger than a preset threshold value or not is judged, so that whether privacy protection needs to be carried out on the data information displayed on the screen in time or not is judged.

In the embodiment of the invention, the overlapping of the colors of the current red channel, the current green channel and the current blue channel is changed by adjusting the intensity values corresponding to the red channel, the green channel and the blue channel in the RGB color mode currently corresponding to the screen on the terminal, so that the condition that sporadic pixel points are displayed on the screen on the terminal and even the display is not visible is obtained, and finally, the information of the screen display data cannot be clearly identified. Further, the corresponding visual angle during the screen display data information at this moment can be monitored simultaneously in the process of adjusting the RGB color mode, when the visual angle corresponding to the screen on the terminal is judged to be equal to the preset threshold value, the displayed data information can be effectively and timely prevented from being peeped by other people while the user on the terminal is not influenced to clearly view, for example, when the corresponding visual angle obtained according to the adjusted RGB color mode is 5 degrees, which is smaller than the preset visual angle (for example, 15 degrees), inconvenience can be brought to the user to look up the terminal screen display data information to a great extent according to the 5-degree visual angle, but correspondingly, if the corresponding visual angle is 30 degrees, other people can be peeped by the screen display data information easily according to the 30-degree visual angle.
The second method for adjusting the corresponding visual angle when the data information is displayed on the screen of the terminal according to the preset privacy mode comprises the following steps: and adjusting the gray value corresponding to the screen on the terminal at present to be equal to a preset threshold value, and controlling the screen on the terminal to display data information according to the adjusted gray value.
Wherein, the gray value is the brightness value of the screen display. In the embodiment of the invention, the data information displayed on the screen can be clearly identified only when the distance between the data information and the screen is within the threshold range of the screen on the terminal by timely adjusting the gray value displayed on the screen, so that the peeping of others is prevented.
The third method for adjusting the corresponding visual angle when the data information is displayed on the screen of the terminal according to the preset privacy mode is as follows: the privacy level and the visual angle corresponding to the screen display information matched with the privacy level can be preset on the terminal, the user can trigger operation through one key, the appointed preset privacy level is selected, the screen on the terminal can automatically match the corresponding visual angle, then the selection is triggered according to one key of the user, the screen of the terminal is controlled to display data information at the appointed visual angle, and privacy protection is achieved.
