Facial Recognition Hits the Tube
British Transport Police are launching a trial of live facial recognition (LFR) on the London Underground, amid discussions about privacy and misidentification. These railway officers are starting at Victoria Underground station, with cameras rolling out across the Tube and Network Rail stations until November. It all began at London Bridge railway in February, aiming to evaluate how this technology performs in a railway environment. The Met is also joining, planning to scan faces in London’s West End and Soho by the end of the year.
How It Works
Live facial recognition captures images within a camera’s view, compares them with a watchlist of suspicious individuals, and sends an alert for the police to review before deciding if further action is warranted. The NEC NeoFace M40 algorithm powers it, reportedly shared across various law enforcement agencies. Chief Superintendent Chris Casey believes this expansion into the Underground will assist in refining its implementation across the network.
Public Concerns and Criticisms
Critics are decidedly labeling it dystopian and invasive, with mistakes leading to innocent individuals being misidentified and apprehended. Ethnic minorities appear more likely to be wrongly identified by these facial algorithms, raising serious concerns. Silkie Carlo of Big Brother Watch depicts a bleak scenario, asserting it’s a troubling expansion that makes Britain resemble China more than a democracy. The Tube sees over 3.7 million trips on a weekday, meaning many faces could be captured by these devices.
What the Survey Says
A survey of 2,000 Brits, conducted by Face Int, revealed that 69% believe the public should have a say in how this technology is utilized. 61% are worried that errors could put innocent individuals at risk, and 57% are concerned about how their facial images are stored. The railway police assure that images not matching the watchlist will be deleted immediately and permanently, but who can say if that will remain consistent in the future.
The Official Line
We inquired with the British Transport Police about public apprehensions, and they referred us back to Chief Superintendent Casey’s remarks. He emphasizes protecting the public, preventing crime, and ensuring justice for wrongdoers, all while using the technology lawfully and transparently. Time will reveal whether the public accepts this, though.
The Final Say
Summary: Big Brother on the Tube
So, there you have it. London’s Underground is undergoing face scanning extensively, while the public isn’t entirely pleased about it. Whether it’s a move toward safety or simply another tick on the surveillance list, only time—and occasional surveys—will reveal the truth.
