Forensics, Anti-forensics and Counter Anti-forensics for JPEG Compressed Images
-With the advancement in information technology and image processing software the manipulation of the images has increased considerably from past few decades. Retouching or tampering of the images has been so prevalent that nowadays one can hardly believe their originality. Image authenticity is done using forgery detection techniques. These methods are broadly classified as active and passive....
متن کاملCombating Anti-forensics of Jpeg Compression
This paper proposes a forensic method for identifying whether an image was previously compressed by JPEG. Though some methods have already been proposed for this purpose, Stamm and Liu’s anti-forensic method disables the detection capabilities of these methods. After analyzing the anti-forensics method, we propose to use the decimal histogram of the coefficients to distinguish the never-compres...
متن کاملA generalized Benford's law for JPEG coefficients and its applications in image forensics
In this paper, a novel statistical model based on Benford’s law for the probability distributions of the first digits of the block-DCT and quantized JPEG coefficients is presented. A parametric logarithmic law, i.e., the generalized Benford’s law, is formulated. Furthermore, some potential applications of this model in image forensics are discussed in this paper, which include the detection of ...
متن کاملImage Statistical Frameworks for Digital Image
IMAGE STATISTICAL FRAMEWORKS FOR DIGITAL IMAGE FORENSICS by Patchara Sutthiwan The advances of digital cameras, scanners, printers, image editing tools, smartphones, tablet personal computers as well as high-speed networks have made a digital image a conventional medium for visual information. Creation, duplication, distribution, or tampering of such a medium can be easily done, which calls for...
متن کاملCountering Counter-Forensics: The Case of JPEG Compression
This paper summarizes several iterations in the cat-andmouse game between digital image forensics and counter-forensics related to an image’s JPEG compression history. Building on the counterforensics algorithm by Stamm et al. [1], we point out a vulnerability in this scheme when a maximum likelihood estimator has no solution. We construct a targeted detector against it, and present an improved...
