An Evaluation of Image Forgery Detection Methods using JPEG Compression Properties

摘要

Detection of forged images based on JPEG compression properties plays a very crucial role in image forensics. Nowadays, JPEG is the most commonly used compression standard. Most of the digital cameras in the market are mainly exporting JPEG file format. It is very important to identify whether an image has been previously JPEG compressed or not. Recently, few successful approaches have been presented, which, making use of the JPEG compression properties, give us various helpful details of the image under consideration. In this paper, we present an evaluation of image forgery detection methods(IFDM) using JPEG compression properties based on various parameters such as the method employed, the feature extracted, the classifier used, the detection accuracy achieved and the limitations identified. The objective of this paper is to identify the research gaps in IFDM.
