Facial recognition tech is spreading everywhere, but it can still be fooled with a bit of face paint. So should we be worried?

Ed Butler speaks to Professor Alan Woodward, professor of computer science at the University of Surrey, and James Stickland, chief executive of facial recognition tech developer Veridium.

Meanwhile the BBC's China media analyst Kerry Allen tells the grim story of a man who tried to use a dead girl's face to get a bank loan. Plus Ed's face is transformed into a Mondrian painting by anti-surveillance activists The Dazzle Club.
