Gotta Catch 'Em All!
Abstract
Biometrics is an area of research where we investigate the identification and authentication of individuals, based on physical or behavioural treats. However, behavioural biometrics goes much further then the well know voice or signature recognition to get access to a system. We can use it for example for continuous authentication to detect session hijacking. In this presentation we will show that behavioural analysis of chat messages in an online conversation can in fact be used to protect children against sexual predators. In such a scenario it is not only important to detect the presence of sexual predators, but also detect them as early as possible! We will describe a system where we use a trained ML model to evaluate individual messages in a conversation and use the results to update a risk value related to the conversation. Extensions to this system will also be discussed.
Short bio
Patrick Bours is a Professor in the area of Biometrics at the Norwegian University of Science and Technology (NTNU) in Gjøvik, Norway. He has an MSc and PhD in discrete mathematics from the Eindhoven University of Technology in Eindhoven, the Netherlands. After obtaining his PhD he has worked for 10 years at the Netherlands National Communication Security Agency (NLNCSA) in the area of crypto as a senior policy member with a specialization in asymmetric crypto and random number generation. In 2005 he moved to Norway and started at Gjøvik University College in a PostDoc position in a project called “Authentication in a health service environment” and has started working in the area of biometrics from then. In 2008 he obtained an Associate Professor position at the same institute and since 2012 he has a full Professor position. In 2016 Gjøvik University College merged with NTNU. Patrick Bours has specialized in behavioural biometrics and in particular gait recognition and keystroke dynamics. He has authored and co-authored over 125 journal and conference papers and has an h-index of 31.
