Abstract

The invention discloses a file read-write permission control method and device, a terminal and a storage medium, and the method comprises the steps of associating an application file with a first application when an application file of the first application is generated in an SD card area of the terminal, and obtaining an associated file; obtaining the authority setting information of the associated file, carrying out the authority setting on the associated file, and obtaining the read-write authority of the associated file; and when a read-write instruction of a second application on the associated file is detected, controlling a read-write operation of the second application on the associated file according to the read-write permission and the read-write instruction, so that the technical problem that an existing file stored in an SD card area of a terminal is easily and randomly read and written by any application, so that the privacy security hidden danger of a user is caused is solved.

Description

technical field [0001] The present invention relates to the technical field of terminals, in particular to a file read and write authority control method, device, terminal and storage medium. Background technique [0002] At present, the terminal storage area is mainly divided into the Data area and the SD card area. The Data area is used to store the private data of the application, such as a database. The private data stored in the Data area is not shared between applications, while the SD card area is It is a public area for storing relatively large files and non-strong privacy data of applications. Currently, any application can read and write any file in any partition of the SD card area. For example, when a user uses WeChat, Many pictures and videos sent by friends are saved, but other applications can directly tamper with or delete these files, causing user privacy and security issues. Contents of the invention [0003] The main purpose of the present invention is ...
