摘　　要：对数字图像取证技术及其研究现状进行介绍，将数字图像取证研究领域按照其研究角度划分为图像来源认证（源识别）和图像篡改取证（篡改检测）两个方面，为现有技术进行综述。针对数字图像来源认证，将现有的技术方法按实现的机理不同分为4大类：基于镜头畸变的方法、基于像素缺陷的方法、基于模式噪声的方法、基于CFA插值的方法。针对图像篡改取证分别介绍了3大类方法的特征及其所属各种典型算法。Digital image forensics technology and research status are introduced, the field of digital image forensics research according to the different research direction is divided into the two aspects： the image authentication source （source） and the image tamper evidence （tamper detection）. For the existing technology was summarized. The implementation mechanism for different methods of digital image authentication technology, the current method is divided into 4 categories： the method based on lens distortion Based, the method based on pixel defect, the method based on the pattern noise, the method based CFA interpolation. For image tamper evidence respectively introduces the characteristics of 3 kinds of methods and the typical algorithm.
