Research on Recognition and Carving Techniques of Monitoring Video Fragments based on Structural Features

摘要

The purpose of this paper is to research how to identify and restructure the binary data fragments which were stored on device efficiently and accurately. Take widely used AVI video file format for example, we proposed a method to identify fragments and carve them into files based on structural features, after the studying of carving technical principle of video and AVI file structure. At last, make a simulation to test the method. The results show that it can recover AVI video files from storage devices without Meta system information and achieved very high percentage of accuracy.
