Abstract

The invention discloses a data management apparatus and method in a file system. The apparatus comprises a path information change part, a task monitoring part, an erasure task execution part, a file name change part and an image reading part. The apparatus is characterized in that the path information change part is used for changing the content indicating path information of the position of a to-be-erased file according to a file erasure request used for file erasure to indicate a predetermined position; the task monitoring part is used for monitoring a state of a task suitable for performing processing related with the file system; and the erasure task execution part is used for executing an erasure task of erasing real data of the file according to the state monitored by the task monitoring part when no predetermined task is being executed except the erasure task. According to the data management apparatus and method, the data can be reliably erased to improve the security level and suppress the problems of low operability and poor other certain processing caused by load increment.

Description

Technical field [0001] The invention relates to a data management device and method in a file system. Background technique [0002] The FAT file system is a known typical system for managing files on a hard disk. The FAT file system usually includes three types of data, including FAT (file allocation table, file allocation table), directory entries and files as real data. When deleting a file from the normal FAT file system, delete the FAT and directory entries that provide information about the location of the real data on the hard disk, but the real data will remain on the hard disk. Therefore, from a security perspective, a A technology that completely erases the real data left on the hard disk. [0003] In fact, this technology erases the real data formed on the hard disk by using special data to rewrite the data remaining in the real data area of ​​the hard disk (especially Patent Document 1: Japanese Patent Application Publication No. 2004- 7059 (page 4-9, figure 1 ),paten...
