VIPP People

The Visual Information Processing and Protection (VIPP) group is an informal research group belonging to the Laboratory of Telematics and Telecommunications (LTT) of the Department of Information Engineering Mathematics of the University of Siena. The VIPP Group was founded in 2005 and it currently consists of 7 members: 1 Professor, 2 post-doc researchers, 1 PhD student, 1 visiting Professor and 2 visiting PhD students. The group welcomes students and researchers wishing to spend a self-funded, research period within the group. Expression of interest should be submitted, together with a CV, to Prof. Mauro Barni.

Official VIPP meetings are scheduled weekly.

The research interests of the VIPP group span the whole area of multimedia security and adversarial signal and information processing, with a particular focus on the protection and authentication of visual information.

Currently, the most active research area is multimedia forensics, with special emphasis on adversarial image forensics, that is the development of image forensic techniques designed in such a way to withstand the attacks of one or more adversaries aiming at system failure. This research activity is partially funded by DARPA (U.S.) through the Medifor project.

Other research areas of the VIPP group include: Adversarial signal and information processing, Data hiding and watermarking, Signal Processing in the Encrypted Domain, Machine Learning applications for Digital ForensicsDistributed detection in adversarial setting.

The VIPP group is especially devoted to keep a high quality research standard, and for this reason it adopts and pushes the Reproducible Signal Processing (RSP) paradigm, whereby the reproducibility of the experimental part of the researches carried out by the group is ensured by providing a precise description of the experiments and, whenever possible, by sharing the software produced by the group with other researchers.



Entropy Special Issue: Information-Theoretic Methods for Deep Learning Based Data Acquisition, Analysis and Security
