And S204, under the condition that the authority information of the user is inconsistent with the pre-stored authority information, carrying out picture shielding processing on the background application program interface thumbnail.

In the embodiment of the invention, the image shielding processing of the background application program interface thumbnail comprises the following steps: and shielding the background application program interface thumbnail of the target application by the target picture. Here, the shielding manner may be covering or replacing; the occlusion range may be all thumbnails or a part of a thumbnail.

In the embodiment of the invention, the biological characteristic information of the current user is verified when the user input is received, and the picture shielding processing is carried out on part or all of the interface thumbnails of the background application program according to the verification result, so that the privacy information of the user can be flexibly protected, the humanization and the individuation of a protection mode are realized, and the user experience is improved.

On the basis of carrying out image shielding processing on the background application program interface thumbnail, the image shielding processing further comprises the following steps: and shielding the background application program icon and the name of the target application by the target picture. Here, when the user sets the target picture as the icon and the name for shielding the target application, the mobile terminal may remind the user that the application type needs to be distinguished through the target picture, and the reminding manner includes, but is not limited to, text prompt or voice prompt.

In the embodiment of the invention, the interface thumbnail, the icon and the name of the background application program are subjected to picture shielding processing at the same time, so that the common protection of the privacy information in the interface thumbnail and the use record of the application program is realized, and the privacy of the use condition of the application program is further improved, thereby protecting the privacy and the safety of a user comprehensively and optimizing the user experience.

In this embodiment of the present invention, S204 further includes:

and acquiring a target picture and target application information. Here, the target picture is used to obscure the background application interface thumbnail of the target application. And selecting the target picture and the target application by the user in the privacy setting interface. For example, after a user enters a privacy protection function through a privacy setting interface entry in a mobile terminal system setting interface, the function interface displays application information and provides options for selecting an application and selecting a picture, wherein the application information display mode may be in a list or grid form. The display sequence of the application programs can be sorted according to the privacy importance degree, and the application programs which are frequently used by the user and relate to the privacy are prioritized. Here, the privacy importance degree may be determined according to data statistics information or preset by a user. It should also be understood that the mobile terminal may provide the function of the user manually arranging the display order of the application list. The function interface may also provide a screening function button for one-touch selection of applications screened according to a preset rule. Here, the filtering rule may be determined according to data statistics.

It should be understood that, in the embodiment of the present invention, the user may select different pictures for each application respectively for occlusion, or may select the same picture for occlusion for multiple applications. The pictures comprise function preset pictures or pictures in a user photo album. Specifically, the function preset pictures are pictures of different styles, such as styles of cartoons, landscapes, businesses, refreshments, and the like, which are stored in advance in the privacy protection function. The user can quickly select the pictures corresponding to the styles by selecting different styles. Here, the function preset picture may also be a target application initial interface picture or an icon picture of the target application.

For example, when the biometric information of the user performing the second input is consistent with the pre-stored permission information, or the second input is matched with the pre-stored gesture, or the password input by the user performing the second input in step S207 is consistent with the pre-stored password, the background program interface thumbnail of the target application which is not subjected to the image occlusion processing is resumed to be displayed. It should be understood that when the comparison result of the authority information in step S207 is inconsistent, the display content of the current background application program interface thumbnail is not changed.

In the embodiment of the invention, the mobile terminal can verify the biological characteristic information of the current user after receiving the input of the user, and carry out the picture shielding processing on the background application program interface thumbnail according to the verification result, and meanwhile, the mobile terminal can restore and display the background application program interface thumbnail which is not subjected to the picture shielding processing according to the authority information verification result of the user executing the second input, so that the privacy information of the user is protected, the humanized opening and closing of the privacy protection function can be realized, and the user experience is improved.
