Referring to fig. 2, a flowchart illustrating steps of embodiment 2 of a method for storing a multimedia file according to the present application is shown, which may specifically include the following steps:

step 201, obtaining a multimedia file;

in an embodiment of the present application, the multimedia file includes: images and videos; the step 201 may include: when an image or video is captured, the image or video is obtained.

The manner in which the mobile terminal captures an image or video may include: capturing an image or video by a camera; intercepting an image or a video by adopting an intercepting program; or receive images or videos sent by other terminals.

Step 202, writing the multimedia file into a multimedia database;

in one example, when the mobile terminal captures an image or video, the mobile terminal stores the image or video in a default multimedia file at the time of capturing the image or video. And then extracting the multimedia file from the multimedia file, and rewriting the multimedia file into a multimedia database with access right.

In another example, when the mobile terminal captures an image or video, the captured image or video may be directly written to a multimedia database having access rights.

Step 203, extracting the characteristic information of the multimedia file;

the mobile terminal extracts feature information from the multimedia file. When the multimedia file comprises images and videos, face feature information in the images and the videos is extracted.

Step 204, comparing the characteristic information of the multimedia file with preset characteristic information, and determining that the preset characteristic information matched with the characteristic information of the multimedia file is target characteristic information; the preset characteristic information corresponds to the access authority level;

in this embodiment of the application, the preset feature information may include preset face feature information. The mobile terminal compares the face feature information extracted from the image and/or the video with preset face feature information, and determines the preset face feature information matched with the face feature information in the image and/or the video as target feature information.

Step 205, determining the access authority level corresponding to the target characteristic information;

the mobile terminal is preset with the corresponding relation between the preset characteristic information and the access authority level. For example, a correspondence between preset face feature information and an access authority level is preset. Different preset face feature information can correspond to different access authority levels and can also correspond to the same access authority level, and the corresponding relation can be specifically set by a user.

And the mobile terminal determines the access authority level corresponding to the target characteristic information according to the preset corresponding relation.

Step 206, configuring the access permission level for the multimedia file in the multimedia database.

For example, for an image stored in a multimedia database, an access authority level determined by face feature information of the image is configured.

The user inputs the facial feature information of the girlfriend/boyfriend into the mobile terminal as preset facial feature information, and configures second access authority for the facial feature information of the girlfriend/boyfriend.

When a user shoots an image of the user by adopting the mobile terminal, the mobile terminal extracts face feature information of the user from the image. The mobile terminal compares the face feature information of the image with preset face feature information, so as to obtain preset face feature information (preset face feature information of the user) matched with the face feature information of the image. The mobile terminal determines that the access authority level of the matched preset face feature information (the preset face feature information of the user) is a first access authority level, and then the first access authority level is configured on the image.

In the substep S12, if the target feature information matched with the image and/or the face feature information in the video is not unique, determining the highest access authority level in the access authority levels corresponding to the target feature information;

sub-step S13, configuring the highest access permission level for the multimedia file.

In the embodiment of the application, when a plurality of pieces of face feature information are extracted from an image or a video, the extracted plurality of pieces of face feature information are matched with the preset face feature information.

If a plurality of pieces of face feature information in the plurality of pieces of face feature information of the image or the video are matched with the preset face feature information, or a plurality of pieces of face feature information in the preset face feature information are matched with the face feature information of the image or the video.
