Embodiment one

A method for displaying private content provided by an embodiment of the present invention is introduced in detail.

Referring to FIG. 1, it shows a flow chart of a method for displaying private content in an embodiment of the present invention, which is applied to a mobile terminal, and the method includes:

Step 101, when displaying private content, acquire characteristic information of users within the visible range of the mobile terminal screen.

In this embodiment, the private content may specifically include private information and private videos, such as business secret files and videos, identity verification information, bank accounts, and the like. The visible range of a mobile terminal is the range in which users can clearly view all content on the screen from different directions. Outside the visible range, viewing the screen will produce color distortion, and even the content displayed on the screen cannot be seen clearly. The characteristic information of the user is information used to identify the identity of the user within the visible range of the mobile terminal, so that the mobile terminal or the user can identify whether other untrustworthy users are viewing private content.

When a mobile terminal displays private content, it needs to obtain the identity information of users within the visible range of the mobile terminal screen. Users outside the visible range of the mobile terminal cannot clearly watch the private content, and the chance of leaking the private content is small.

Step 102: According to the acquired feature information, it is judged whether there is a setting user within the visible range.

In this embodiment, the mobile terminal has obtained the identity information of users within the visible range, and judges whether there is a set user within the visible range of the mobile terminal according to the obtained identity information, so as to take corresponding measures according to the judgment result.

Wherein, a set user is a user whose mobile terminal can display private content normally, and a non-set user is a user whose mobile terminal does not display private content. The mobile terminal pre-sets the set users. In the embodiment of the present invention, the number of set users is not limited in detail, and can be set according to actual conditions.

Step 103, if there is no set user within the visible range, or a non-set user is detected within the visible range, start the screen lock function.

In this embodiment, when the set user does not exist within the visible range, for example, the set user does not use the mobile terminal, or the mobile terminal is taken away during viewing, the mobile terminal activates the screen lock function and no longer displays private content.

When a non-set user is detected within the visible range, for example, in addition to the set user watching private content, the non-set user may also watch private content within the visible range of the mobile terminal, then the mobile terminal starts the lock screen function, Do not show private content again.

To sum up, in the embodiment of the present invention, when displaying private content, the mobile terminal acquires characteristic information of users within the visible range of the mobile terminal; according to the acquired characteristic information, it is judged whether there is a set user within the visible range; if If there is no set user within the visible range, or if a non-set user is detected within the visible range, the lock screen function will be activated, and the private content will not be displayed after the screen is locked, which protects personal privacy and avoids the leakage of personal privacy.

Embodiment two

Referring to FIG. 2 , it shows a flow chart of a method for displaying private content in another embodiment of the present invention.

Step 201, prompting the user to stay in the shooting area of the front camera for a long time; or prompting the user to stay in the fingerprint identification area for a long time.

In this embodiment, when acquiring the user's feature information within the visible range of the mobile terminal screen, in order to ensure accurate information acquisition and prevent the user from locking the screen due to misoperation during viewing, prompt information is generated on the mobile terminal screen.

The mobile terminal can be preset with a front camera, and the front camera can be a wide-angle camera. The wide-angle camera has a wide angle of view, and the wide-angle camera can capture a large area. When the mobile terminal adopts the front wide-angle camera to obtain the feature information of the user within the visible range of the front end of the mobile terminal, the user is prompted to stay in the shooting area for a long time.

The mobile terminal may also be preset with a fingerprint recognition sensor, and the user's fingerprint data may be collected through the fingerprint recognition sensor. When the mobile terminal adopts the fingerprint identification sensor to collect the fingerprint data of the user, the user is prompted to keep the finger in the fingerprint identification area for a long time.

The mobile terminal can also use other devices to obtain the user's characteristic information, and the generated prompt information corresponds to the manner of obtaining the characteristic information. The embodiment of the present invention does not limit this in detail, and it can be set according to the actual situation.

In this embodiment, a private mode for protecting privacy can also be set on the mobile terminal, and the user can choose whether to enable the private mode for protecting privacy according to requirements. The information judges whether there is a set user, and makes corresponding measures according to the judgment result. If the user chooses not to enable the private mode, the mobile terminal will not perform the process of acquiring feature information and judging when displaying private content. The private mode can be preset in the mobile terminal system, or can be realized by installing an application program, which is not limited in detail in the embodiment of the present invention, and can be set according to actual conditions.

Step 202, acquiring feature information of users within the visible range of the mobile terminal screen.

In this embodiment, in order to identify whether there is a set user within the visible range, the feature information of the user within the visible range of the mobile terminal screen is obtained. The feature information may specifically include at least one of fingerprint data, iris data, and facial feature data. kind. For example, fingerprint data or iris data of users within the visible range of the mobile terminal are acquired. In this embodiment, the characteristic information to be acquired is not limited in detail, and may be set according to actual conditions.

Step 203, comparing the acquired feature information with preset user feature information.

In this embodiment, before comparing the characteristic information, the mobile terminal obtains the characteristic information of the set user in advance, which provides a basis for identifying whether the set user exists within the visible range of the screen of the mobile terminal. The set users of the mobile terminal may include the owner of the mobile terminal, and may also include users trusted by the owner of the mobile terminal. The embodiment of the present invention does not limit the number of set users in detail, and can be set according to actual conditions. After the feature information of the user is obtained, the feature information is stored as the feature information of the set user, and when the feature information is to be compared, data is extracted from the set user. When storing, the identifier set by the user for the characteristic information may be received, or may be stored as a default characteristic information identifier, which is not limited in detail in the embodiment of the present invention, and may be set according to the actual situation.

The acquired feature information is compared with the preset user feature information. For example, to obtain the user's fingerprint data, compare the obtained fingerprint data with the preset user's fingerprint data; obtain the user's iris data, then compare the obtained iris data with the preset user's iris data. The acquired feature information and the preset user feature information need to be compared one by one, specifically, the acquired feature information is compared with the pre-stored feature information one by one. For example, after obtaining the characteristic information A and B, and setting the characteristic information of the user as X, Y, and Z, the obtained characteristic information A is compared with the characteristic information X, Y, and Z of the set user one by one, and then Compare the acquired characteristic information B with the characteristic information X, Y, Z of the set user one by one.

Step 204, if the comparison results are inconsistent, it is determined that there is a non-set user in the visible range

In this embodiment, the acquired characteristic information is compared with the characteristic information of the set user, and if one of the acquired characteristic information is inconsistent with the characteristic information of the set user, it is determined that the comparison result is inconsistent. For example, if the characteristic information A and B are obtained, and the characteristic information of the user is set as X, Y, and Z, the obtained characteristic information A is consistent with the characteristic information X of the set user, but the obtained characteristic information B is consistent with the set user characteristic information. The comparison of characteristic information X, Y, and Z of the given user is inconsistent, and it is determined that the obtained characteristic information B is inconsistent with the comparison result of the characteristic information of the set user.

When the comparison results are inconsistent, it means that the acquired characteristic information does not belong to the characteristic information of the set user, and there is a user not belonging to the set user within the visible range of the mobile terminal, that is, there is a non-set user within the visible range.

In this embodiment, if no feature information is acquired within the visible range of the mobile terminal, it means that there is no user within the visible range of the mobile terminal. Specifically, the mobile terminal uses the front-facing camera to obtain the user's characteristic information. When no characteristic information is obtained in the shooting area of the camera, it means that no user information is captured, and it is determined that there is no user within the visible range; the mobile terminal uses the fingerprint The recognition sensor collects the user's fingerprint data, if no user's fingerprint data is collected in the fingerprint recognition area, indicating that the user's finger is not in the fingerprint recognition area, then it is determined that there is no user within the visible range.

Step 205, if there is no set user within the visible range, or a non-set user is detected within the visible range, start the screen lock function.

In this embodiment, when there is no user within the visible range, that is, there is no set user within the visible range. If there is no set user within the visible range, or if there is a non-set user within the visible range, the lock screen function will not display private content.

To sum up, in the embodiment of the present invention, the mobile terminal prompts the user to stay in the shooting area or the fingerprint recognition area; pre-acquires and stores the characteristic information of the set user; The obtained feature information is compared with the pre-stored feature information of the set user. If the comparison results are inconsistent, it means that there are non-set users in the visible range. If the feature information is not obtained, it means that there is no user in the visible range; If there is no set user in the visible range, or there is a non-set user in the visible range, the lock screen function will be activated, and the private content will not be displayed after the screen is locked, which protects personal privacy and avoids the leakage of personal privacy.

Embodiment three

Referring to FIG. 3 , it shows a flowchart of a method for displaying private content in another embodiment of the present invention.

The image processing is completed and set in the area of the screen that does not block the private content. While watching the private content, the user of the mobile terminal can also see the images of all users within the visible range of the mobile terminal. The user judges the visible content of the mobile terminal based on the image Whether there are non-set users within the range, if there are no set users, the user will continue to watch private content, if there are non-set users, the user will take corresponding measures.

Step 304, receiving a screen lock operation triggered after the user recognizes that there is a non-configured user within the visible range of the mobile terminal.

In this embodiment, when the user determines that there is a non-set user within the visible range of the mobile terminal, a screen lock operation is triggered to protect privacy, and the mobile terminal receives the screen lock operation triggered by the user. Specifically, when the user recognizes that there is a non-set user within the visible range of the mobile terminal, the user can trigger the screen lock operation by pressing the screen lock button.

The operation of triggering the lock screen can also be done so that the mobile terminal cannot obtain feature information. For example, if the user leaves the shooting area of the front camera, or the finger leaves the fingerprint recognition area, the mobile terminal cannot obtain the user's iris data, facial features, etc. data, or the fingerprint data cannot be recognized.

Step 305, when displaying private content, use the rear camera to capture an environment image.

In this embodiment, the mobile terminal has a rear camera, and the rear camera can be used to capture an environment image, that is, an image of the front end of the user, when displaying content.

Step 305 and step 302 do not have a sequence problem, and can be performed at the same time. Specifically, the mobile terminal uses the front and rear cameras to capture images within the visible range of the mobile terminal and environmental images at the same time.

In step 306, the captured image is transparently processed and placed in an area of the screen where private content is not blocked, so that the setting user can judge whether there is danger ahead.

In this embodiment, the user may not notice whether the front-end environment is dangerous when watching the private content, but the captured environmental image is transparently processed and set in an area of the screen that does not block the private content, so that the user can watch the private content, At the same time, pay attention to whether there is danger ahead through the environmental image on the screen.

Step 306 and step 303 do not have a sequence problem, and can be performed at the same time. Specifically, the mobile terminal performs transparent processing on the captured image within the visible range of the mobile terminal and the environmental image at the same time. area. The user of the mobile terminal can not only judge whether there is a non-set user in the visible range of the mobile terminal through the image in the visible range of the mobile terminal, but also judge whether there is danger ahead according to the environmental image.

Step 307, start the lock screen function.

In this embodiment, the mobile terminal receives a screen lock operation triggered by the user, and starts the screen lock function.

To sum up, the mobile terminal in the embodiment of the present invention displays prompt information to the user, takes images within the visible range of the mobile terminal and environmental images through the front and rear cameras, and transparently processes the images after shooting and sets them on the screen so as not to block private content. area. The user of the mobile terminal can not only judge whether there is a non-set user in the visible range of the mobile terminal through the image in the visible range of the mobile terminal, which protects personal privacy, but also judges whether there is danger ahead according to the environmental image.
