Today manipulation of digital images has become easy due to powerful computers,
advanced photo-editing software packages and high resolution capturing devices. Verifying …

The aim of this survey is to provide a comprehensive overview of the state of the art in the
area of image forensics. These techniques have been designed to identify the source of a …

Identifying the authenticity and processing history of an image is an important task in
multimedia forensics. By analyzing traces left by different image manipulations, researchers …

Due to the wide diffusion of JPEG coding standard, the image forensic community has
devoted significant attention to the development of double JPEG (DJPEG) compression …

In this paper, we propose a forensic algorithm to discriminate between original and forged
regions in JPEG images, under the hypothesis that the tampered image presents a double …

The last decade has witnessed a multifold growth of image data courtesy of the emergence
of social networking services like Facebook, Instagram, LinkedIn etc. The major menace …

In this paper, a simple yet reliable algorithm to detect the presence of nonaligned double
JPEG compression (NA-JPEG) in compressed images is proposed. The method evaluates a …

Verifying the integrity of digital images and detecting the traces of tampering without using
any protecting pre-extracted or pre-embedded information have become an important and …

It is often desirable to determine if an image has been modified in any way from its original
recording. The JPEG format affords engineers many implementation trade-offs which give …

With the development of sophisticated image editing and manipulation tools, the originality
and authenticity of a digital image is usually hard to determine visually. In order to detect …
