Forensic analyses of digital images rely heavily on the traces of in-camera and out-camera
processes left on the acquired images. Such traces represent a sort of camera fingerprint. If …

A complex processing chain is applied from the moment a raw image is acquired until the
final image is obtained. This process transforms the originally Poisson-distributed noise into …

Image manipulation detection algorithms designed to identify local anomalies often rely on
the manipulated regions being``sufficiently''different from the rest of the non-tampered …

As image tampering becomes ever more sophisticated and commonplace, the need for
image forensics algorithms that can accurately and quickly detect forgeries grows. In this …

The internet is a vast and rapidly changing landscape. For every new algorithm invented to
increase the security and reliability of our society, an adversarial group coalesces in …

Devido aos avanços nas tecnologias de aquisição de imagens e dos softwares de edição,
