Problems solved by technology

[0003] In related technologies, the operation authority of the file is controlled by setting the authority of the logged-in user, or setting a hidden space to protect the file, such as a general user account can access user files, an administrator account can access system files, etc. There are no restrictions on the access control of the process, so it is impossible to protect the malicious operation of the file by using the trusted process, and the hidden space can only passively protect the file, which affects the normal use of users
[0004] For the above-mentioned problems existing in related technologies, no effective solution has been found yet

Abstract

The invention provides a file access control method and device, a storage medium and an electronic device, and the method comprises the steps of detecting an operation behavior of accessing a target file; locally identifying an operation main body of the operation behavior in a server, the operation main body being a process for triggering the operation behavior; and when the operation subject does not have the access permission to the target file, intercepting the operation behavior. Through the present invention, the technical problem of low file security in related technologies is solved, and the file security is improved.

Description

technical field [0001] The invention relates to the field of computers, in particular to a method and device for controlling access to files, a storage medium, and an electronic device. Background technique [0002] Files are a common form of information data stored in devices. Due to their wide use and transmission, files can usually be accessed or even edited by any operating subject. [0003] In related technologies, the operation authority of the file is controlled by setting the authority of the login user, or setting a hidden space to protect the file, such as a general user account can access user files, an administrator account can access system files, etc. There are no restrictions on the access control of the process, so it cannot prevent malicious operations on files by using trusted processes, and the hidden space can only passively protect files, which affects the normal use of users. [0004] Aiming at the above-mentioned problems existing in related technolog...
