Abstract

The invention discloses a system for safely deleting a file, which comprises a file system driving module, a judgment module, a graphic formula module, a comparison module and a deleting module. The system executes the operation through a request sent by an operating system, judges the type of the file request, and then deletes the file. On the premise that no artificial participation of users is needed, the system safely and thoroughly deletes the relevant data, and thereby not resulting in the disclosure of confidential data.

Description

technical field [0001] The invention relates to a system for safely deleting files, in particular to a system for safely deleting confidential files in a computer. Background technique [0002] Usually in some confidential environments such as state agencies and enterprises, computers contain a large number of confidential documents or sensitive data, so the management of these documents and data is very important. However, when moving or deleting these data on the computer, usually the operating system cannot clear the data, but only deletes the location where the data is saved, which will leave an opportunity for confidential data leakage. At present, some recovery software can use the above-mentioned vulnerabilities to obtain these data, and then cause huge losses to the corresponding enterprises or units or even the country. Contents of the invention [0003] In order to solve the above-mentioned problems and defects, the purpose of the present invention is to provide...
