    现有相机拍摄的图像大部分以JPEG格式存储，拍摄后相机会自动把一些与图像相关的信息保存在JPEG头部，数字图像处理软件如Adobe Photoshop，GIMP等在JPEG压缩过程中也进行相同操作。数字图像取证是取证技术的一个重要方面，本文将重点介绍基于JPEG Header信息的图像取证技术。

    Most of the existing camera images are stored in JPEG format, after shooting some information of the image will be saved in the header of JPEG, even digital image processing software like Adobe Photoshop, GIMP etc have the same operation in the JPEG compression process. Digital image forensic is an important part of forensic technology. This paper will focus on introduce some useful techniques of image forensics that base on JPEG header
