Short Bio

Head of FORLAB, Multimedia Forensics Laboratory

IEEE Fellow, and member of the IEEE Information Forensics and Security Technical Committee.

Alessandro Piva received the Laurea degree (cum laude) in Electronics Engineering (Telecommunication branch) in 1995 from the University of Firenze and the Ph.D. degree in “Information and Telecommunications Engineering” from the University of Florence, discussing the thesis “A DCT-Domain Watermarking System for Copyright Protection of Digital Images”.

He received a Research Grant on “Watermarking of digital images for secure distribution over telematic networks” obtained from the Department of Electronics and Telecommunications, University of Florence, from 2000 to 2002. From 2002 until 2004 he was Research Scientist at the National Inter-university Consortium for Telecommunications (CNIT).

From January 2005 until October 2014, he was Assistant Professor at the Department of Electronics and Telecommunications, now Department of Information Engineering, of the University of Florence. Since November 2014, he is Associate Professor at the Department of Information Engineering, University of Florence.

He’s also involved in the research activities of CNIT and of the Media Integration and Communication Center of Excellence (MICC).

Research interests

Multimedia security and protection, with particular reference to digital watermarking and multimedia forensics.

He started working on the use of digital watermarking for image protection since the late nineties. For more than 15 years, he contributed to build a solid theoretical framework for watermarking and developed a wide set of practical methods bridging the gap between theory and practice. More specifically, he has contributed to the development of robust digital watermarking techniques for digital images and video sequences; later on, he has developed some secure watermarking methods for multimedia content protection through the adoption of innovative cryptographic solutions. Regarding multimedia forensics, he contributed to the design of statistical models for the detection and localization of traces left by double compression in images, video and audio files; moreover, he worked on the reliability and efficiency of image forensic tools in practical applications, mainly through the exploitation of decision fusion methods. He also developed a number of forensic techniques exploiting the traces left by the acquisition devices, as well as geometric inconsistencies often associated to image tampering.

Image and Video Processing for Cultural Heritage, medical and industrial applications

in this field he contributed to the development of image processing algorithms that can help the restorers in the analysis during the restoration phases; on the other hand, by means of image processing it is possible to carry out a sort of virtual restoration. The developed tools have been integrated into a package named ArtShop. Multispectral imaging techniques were applied on the CH field to achieve material localization and identification on painting surfaces, and on medical field for early diagnosis of melanoma. Analysis of angiographies for the automatic measuring of diameter and temporal pulsatility in blood vessels was studied; parameter estimation for the automatic recognition of textile (cheratinic) fibres was also studied.

Other research interests included video coding techniques, and multimedia applications in the Cultural Heritage field.
