Abstract

The invention proposes a method for protecting operating system partitions, including: creating a virtual memory space, and mounting the virtual memory space on the first directory; mounting the physical storage space actually storing the system files of the operating system on the second directory; directory; create a user-mode file system on the mount point of the operating system partition to be protected, and control the user-mode file system to monitor request events for file system operations on the operating system partition to be protected; determine the target file corresponding to the request event , according to the request event and the target file, access the second directory to read the target file in the physical storage space, or access the first directory to write to the target file The operation writes into the virtual memory space. Correspondingly, the present invention also proposes a protection device for the operating system partition. Through the technical solution, the protection of the system storage partition can be realized, and the system files can be prevented from being tampered with by malicious programs.

Description

technical field [0001] The present invention relates to the technical field of terminals, in particular to a method for protecting an operating system partition, a device for protecting an operating system partition, and a terminal. Background technique [0002] At present, some mobile phone systems of some manufacturers detect that there are non-factory-built files written, and they will delete them at the next boot; or extract the modified files replaced by source files from a backup partition or data package. [0003] The existing scheme has the following problems: [0004] It is necessary to back up the system partition or provide backups of all applications and programs, which takes up a large amount of storage space, and these spaces are fixedly allocated. [0005] For example, the system partition space of an Android mobile phone currently has more than 1 GB, and whether it is a backup partition or providing application backup, it will take up more than 1 GB of stora...
