Abstract

The embodiment of the invention provides a file crushing method and device based on a domestic operating system and electronic equipment, and belongs to the technical field of information security, and the method comprises the following steps: 1, acquiring meta-information of a file to be crushed; 2, analyzing the meta-information, obtaining a storage area of the file under the condition that thefile data needs to be crushed, and going to the step 3; otherwise, turning to the step 4; 3, covering the storage area with preset data or random data; 4, deleting files. Compared with the prior art,in the file crushing method based on a domestic operating system, a file system of a domestic operating system is analyzed, the storage structure of the file is obtained, the file type is distinguished according to the storage structure characteristics of the file to smash the file data, and a technical means for recovering the file after the file is smashed by mistake is provided on the basis, sothat a domestic operating system user can smash the file data as required and recover the file data as required.

Description

technical field [0001] The invention relates to the technical field of information security, in particular to a file shredding method, device and electronic equipment based on a domestic operating system. Background technique [0002] Each file stored in the hard disk in the system can be divided into two parts: the file node and the data area for storing data. File nodes are used to record information such as file names and file attributes, while real data is stored in the data area. The ordinary deletion that is usually done is actually marking the file for deletion to free up space, but the real content of the file is still stored in the data area and has not been deleted. It is necessary to wait until the future data is written and overwrite this data area, so as to completely delete the original data. It is not erased from the disk unless it is overwritten by later saved data. [0003] According to the principle of file deletion, to completely delete data, the only w...
