Abstract

With the increasing popularity of digital media and the ubiquitous availability of media editing software, innocuous multimedia are easily tampered for malicious purposes. Copy-move forgery is one important category of image forgery, in which a part of an image is duplicated, and substitutes another part of the same image at a different location. Many schemes have been proposed to detect and locate the forged regions. However, these schemes fail when the copied region is affected by post-processing operations before being pasted. To rectify the problem and further improve the detection accuracy, we propose a robust copy-move forgery detection method based on dual-transform to detect such specific artifacts, in which a cascade of Radon transform (RT) and Discrete Cosine Transform (DCT) is used. It will be shown that the dual-transform coefficients well conform the efficient assumption and therefore leads to more robust feature extraction results. Experimental results demonstrate that our method is robust not only to noise contamination, blurring, and JPEG compression, but also to region scaling, rotation and flipping, respectively.
