In this episode, we chat to Dr Leonie Tanczer, a Lecturer in International Security and Emerging Technologies at UCL and Principle Investigator on the Gender and IoT project.  Leonie discusses why online safety and security are not the same when it comes to protection online; how to identify bad actors while protecting people’s privacy; how we can use ‘threat modelling’ to account for and envision harmful unintended uses of technologies, and how to tackle bad behaviour online that is not yet illegal.
