The analysis and design of Linux file system based on computer forensic

Ext2, a basic file system of Linux operating system, can conserve and manage a lot of important file information. Mining and analyzing the useful data of the Linux operating system have become important means and research directions of computer forensic analysis. In this paper, after the detailed analysis and research of storage principle of Ext2 file system, the object-oriented method is proposed to design the parsing platform of Linux file system. By parsing the Binary data files storing on the disk, all the file information extracted is converted into the form of user-friendly interface. Meanwhile, it provides plenty of useful interfaces for the computer forensic analysis, which will be an important information-gaining tool for the computer forensics on Linux operating system.
