London stations facial recognition trial ends in false positive
Original: Trial of live facial recognition in London stations ends with a false positive and no arrests
A six-month trial of live facial recognition at London railway stations ended with a single incorrect alert, no arrests and a £320,000 bill, a Freedom of Information request has revealed. The scheme consumed almost 100 hours of police time. Critics say the outcome underlines concerns about the technology's accuracy, cost and civil liberties implications, while raising questions about how public money is spent on policing tools.
Why now: The poor cost-effectiveness and the false positive fuel ongoing debate over police use of facial recognition technology.
