摘要

数字图像篡改技术的发展促进了图像取证领域的研究。图像篡改可以在各种图像格式上发现，例如联合摄影专家组(JPEG)。JPEG是设备和应用程序支持的最常见的格式。因此，研究人员一直在研究JPEG算法在图像取证中的实现。本文对JPEG压缩、图像拼接、复制移动和图像修饰等不同类型的图像篡改进行了误差水平分析(Error Level Analysis, ELA)技术的评价。实验结果表明，该算法在JPEG压缩、图像拼接和图像修饰伪造中具有较好的可靠性。

An evaluation of Error Level Analysis in image forensics

The advancement in digital image tampering has encouraged studies in the image forensics fields. The image tampering can be found over various image formats such as Joint Photographic Experts Group (JPEG). JPEG is the most common format that supported by devices and applications. Therefore, researchers have been studying the implementation of JPEG algorithm in the image forensics. In this paper, the Error Level Analysis (ELA) technique was evaluated with different types of image tampering, including JPEG compression, image splicing, copy-move and image retouching. From the experiment, the ELA showed reliability with JPEG compression, image splicing and image retouching forgery.
