With facial recognition technology you can take pictures of people in the street, run them through publicly available photographs online, and get a match.
You would have heard this statement if you had been listening to the 20 September 2016 episode of Seriously on BBC Radio 4, called ‘The Online Identity Crisis’. I only heard it yesterday, though, as I caught up with it by podcast. It did, however, set me thinking. Just how likely, or easy, is it that someone should take a photo of me in the street, run said image through facial recognition software, and be able to identify me?
