“…Review of the literature revealed that several researchers have proposed anti-forensic strategies that have been shown to deceive forensic schemes designed to detect forgeries in digital images [102][103][104][105][106][107][108][109][110][111].…”

“…However, if a forger alters the encoded video directly and creates no second-quantization spatial and/or temporal artifacts, the research in [42,46,50,113,119] would be rendered ineffectual. Furthermore, the anti-forensic approach proposed in [111] seems to have the potential to be molded into a potent digital video antiforensic tool.…”

“…Anti-forensics techniques are developed by forgers to remove or falsify statistical fingerprints of certain image manipulation, aiming to deceive the forensics detectors. Many anti-forensics techniques including undetectable resampling [10], JPEG compression [11] and contrast enhancement [12,13] etc. have been proposed.…”

Abstract. In this paper, we present a unified understanding on the formal performance evaluation for image manipulation forensics techniques. With hypothesis testing model, security is qualified as the difficulty for defeating an existing forensics system and making it generate two types of forensic errors, i.e., missing and false alarm detection. We point out that the security on false alarm risk, which is rarely addressed in current literatures, is equally significant for evaluating the performance of manipulation forensics techniques. With a case study on resampling-based composition forensics detector, both qualitative analyses and experimental results verify the correctness and rationality of our understanding on manipulation forensics security.

“…Bohme and kirchner [23] in 2013 framed a categorization of forensic methods and pointed out that stamm's anti forensic has not been tested against median filtering forensic detectors so is also evident. Recently, Fan et al in their paper [24] proposed an improved method of JPEG anti-forensics, with a higher visual quality of images. They employed variation based minimization for de-blocking to fool forensic detectors.…”

Abstract---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. Aim of this paper is to give state of art for a passive detection technique i.e. JPEG double compression. Its forensics, anti-forensics and counter anti-forensics is presented with a review of technologies that exist so far.
