Abstract

Image Forensics has already achieved great results for the source camera identification task on images. Standard approaches for data coming from Social Network Platforms cannot be applied due to the different (and unknown) involved processes (e.g., scaling, compression, etc.). Over 1 billion images are shared each day on the Internet and obtaining information about their history from the moment they were acquired could be exploited for investigation purposes. A preliminary classification engine for the reconstruction of the history of an image  to understand which Social Network Platform has processed an image and the software application used to perform the image upload will be presented.

About the Speaker

Sebastiano Battiato is full professor of Computer Science at University of Catania. He received his degree in computer science (summa cum laude) in 1995 from University of Catania and his Ph.D. in Computer Science and Applied Mathematics from University of Naples in 1999. From 1999 to 2003 he was the leader of the “Imaging” team at STMicroelectronics in Catania. He joined the Department of Mathematics and Computer Science at the University of Catania in 2004 (respectively as assistant professor, associate professor in 2011 and full professor in 2016). He is currently Chairman of the undergraduate program in Computer Science, and  Rector's delegate for Education (postgraduates and Phd). He is involved in research and directorship of the IPLab research lab (http://iplab.dmi.unict.it). He coordinates IPLab participation to large scale projects funded by national and international funding bodies, as well as by private companies. Prof. Battiato has participated as principal investigator in many international and national research projects.His research interests include image enhancement and processing, image coding, camera imaging technology and multimedia forensics. He has edited 6 books  and co-authored about 200 papers in international journals, conference proceedings and book chapters. Guest editor of several special issues published on International Journals. He is also co-inventor of 22 international patents, reviewer for several international journals, and he has been regularly a member of numerous international conference committees.  Chair of several international events (ICIAP 2017, VINEPA 2016, ACIVS 2015, VAAM2014-2015-2016, VISAPP2012-2015, IWCV2012, ECCV2012, ICIAP 2011, ACM MiFor 2010-2011, SPIE EI Digital Photography 2011-2012-2013, etc.). He is an associate editor of the SPIE Journal of Electronic Imaging. He is the recipient of the 2011 Best Associate Editor Award of the IEEE Transactions on Circuits and Systems for Video Technology. He is director (and co-founder) of the International Computer Vision Summer School (ICVSS), Sicily, Italy. He is a senior member of the IEEE.
