Ben Grosser: cyber-security and ominous gibberish

Kim Hill talks to Ben Grosser, Assistant Professor in the School of Art & Design at the University of Illinois, and a faculty affiliate at the National Center for Supercomputing Applications. He is also an artist focused on cyber-security who has been described as the "unrivaled king of ominous gibberish". His works include the Interactive Robotic Painting Machine, and the Gmail extension Scaremail, which aims to drown the National Security Agency in nonsense. He joins a roster of security experts, academics, former spies, and privacy advocates, who offer perspectives on surveillance in the new interactive documentary I Spy, created by Justin Pemberton (Chasing Great) and filmed across the Five Eyes countries (USA, UK, Canada, Australia and New Zealand).
