The Research of Fast File Destruction Based on NTFS

Part of the Advances in Intelligent and Soft Computing book series (AINSC, volume 146)

Abstract

NTFS has become the main file system of Windows. Computer users access data by file system. While deleting a file, the file system only makes some marks but not erase the MFT record and data field, it leaves many traces on the disk. Through certain data recovery means, the deleted file still can be reconstruction. Therefore, file destruction is crucial importance to some secret files. This paper, not only do we introduce the basal principle of NTFS, but also propose an efficient method to destroy file or directory by analyzing the change of file system while deleting a file. This research has significant value in computer privacy protection, classified protection of security information and anti-forensics.
