In this talk, Dr Andrew D. Bagdanov, Dr Massimo Iuliani, Dr Dasara Shullani, Dr Daniele Baracchi & Simone Magistri will present the results of the research activity on multimedia content security carried out at the Information Engineering Department (DINFO) at the University of Florence. First, we will give a short introduction to the three main approaches to the forensic analysis of images and videos (container-, content-, and physics-based), and we will describe some recent works on these topics. Then, we will show some real-world forensic cases where these methods can be applied. Finally, we will talk about challenges and opportunities arising from the application of machine learning to Data Hiding and Multimedia Forensics, and we will conclude the seminar by delving into a recent publication that investigates applications of Continual Learning to social network media source identification.
