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 …

We are currently on a verge of a revolution in digital photography. Developments in
computational imaging and adoption of artificial intelligence have spawned new editing …

As a retouching manipulation, contrast enhancement is typically used to adjust the global
brightness and contrast of digital images. Malicious users may also perform contrast …

Image splicing is a very common image manipulation technique that is sometimes used for
malicious purposes. A splicing detection and localization algorithm usually takes an input …

In recent decades, a significant research effort has been devoted to the development of
forensic tools for retrieving information and detecting possible tampering of multimedia …

We introduce a theoretical framework in which to cast the source identification problem.
Thanks to the adoption of a game-theoretic approach, the proposed framework permits us to …

Detection of contrast adjustments in the presence of JPEG post processing is known to be a
challenging task. JPEG post processing is often applied innocently, as JPEG is the most …

Camera model identification is a fundamental task for many investigative activities, and is
drawing great attention in the research community. In this context, convolutional neural …

As technology advances and develops, the need for strong and simple authentication
mechanisms that can help protect data intensifies. The contemporary approach to giving …

This paper proposes a JPEG anti-forensic method, which aims at removing from a given
image the footprints left by JPEG compression, in both the spatial domain and DCT domain …
