A copy-move counterfeit is created by copying and pasting content within the same image and, potentially, processing it later. In recent years, the detection of copy counterfeits has become one of the most investigated topics in the forensic blind image. A considerable number of different algorithms have been proposed focusing on different types of postprocessed copies. In this paper, we intend to answer which copy and motion falsification detection algorithms and processing steps (for example, coincidence, filtering, detection of atypical values, estimation of related transformation) perform better in several postprocessing scenarios.
The objective of our analysis is to evaluate the performance of previously proposed sets of characteristics. We achieve this by launching existing algorithms in a common pipeline. In this article, we examine the 15 most prominent feature sets. The detection performance was analyzed on a per-image basis and on a per-pixel basis. We have created a challenging set of real-world motion copy data and a software framework for systematic image manipulation. Experiments show that features based on the Sift and Surf key point, as well as block-based DCT, DWT, KPCA, PCA and Zernike functions, work very well. These feature sets exhibit the best robustness against various sources of noise and sampling, while reliably identifying the copied regions.
Digital images are easy to manipulate and edit due to the availability of powerful image processing and editing software. Today, it is possible to add or remove important features of an image without leaving obvious traces of manipulation. As digital cameras and camcorders replace their analog counterparts, the need to authenticate digital images, validate their content and detect counterfeits will only increase. Detection of malicious manipulation with digital images (digital forgery) is the subject of this work. In particular, in the detection of a special type of digital counterfeiting - the copy-move attack in which a part of the image is copied and pasted elsewhere in the image with the intention of covering an important characteristic of the image . In this article, we investigated the problem of detecting counterfeit copies and described an efficient and reliable detection method. The method can successfully detect the forged part even when the copied area is enhanced or retouched to merge with the background and when the forged image is saved in a lossy format such as JPEG. The performance of the proposed method is demonstrated in several forged images.
