Prof. Fernando Pérez-González gave an invited talk on September 28, 2015 at the Royal Flemish Academy on Arts and Sciences, Brussels, Belgium. The Academy organizes the 6th Contact Forum on "Coding Theory and Cryptography", where Prof. Pérez-González will speak about "adversarial signal processing". This emerging topic blends together information theory, game theory and detection theory to develop optimal solutions to signal processing problems in which there is an adversary trying to make malevolent usage of the system. In November 2015, Fernando also taught a half-tutorial at IEEE Workshop on Information Forensics and Security on this same topic, jointly with Prof. Mauro Barni of University of Siena.
