Quantization lattice estimation for multimedia forensics
2013 IEEE International Conference on Image Processing, 2013The most widely used information lossy source coding schemes for multimedia signals rely on the quantization of the content samples in a linearly transformed domain. A number of forensic applications (e.g., processing history estimation, tampering detection, software identification) can be posed as the estimation of the equivalent lattice quantizer ...

Threat Models and Games for Adversarial Multimedia Forensics
Proceedings of the 2nd International Workshop on Multimedia Forensics and Security, 2017We define a number of threat models to describe the goals, the available information and the actions characterising the behaviour of a possible attacker in multimedia forensic scenarios. We distinguish between an investigative scenario, wherein the forensic analysis is used to guide the investigative action and a use-in-court scenario, wherein forensic

Adversarial Multimedia Forensics: Overview and Challenges Ahead
2018 26th European Signal Processing Conference (EUSIPCO), 2018In recent decades, a significant research effort has been devoted to the development of forensic tools for retrieving information and detecting possible tampering of multimedia documents. A number of counter-forensic tools have been developed as well in order to impede a correct analysis.
