A six-month live facial recognition technology (LFR) trial in London’s railway stations has been found to have led to one false match against a watchlist of suspects - and no arrests.
The trial, which cost more than £320,000 and took up almost 100 hours of police officers’ time, saw more than half a million faces scanned between February and July this year, according to a freedom of information document obtained by Liberty Investigates and The Guardian.
