Facial recognition technology is "dangerously inaccurate"

Police

The Metropolitan Police's use of facial recognition is misidentifying innocent people as wanted criminals more than nine times out of 10, according to a privacy campaign group.

Civil liberties organisation Big Brother Watch published its findings into the Met's use of facial recognition technology in a report that it is set to present to Parliament later today.

The Met uses the technology to match people's faces against computer databases of criminals via CCTV and other cameras and they have deployed at numerous events, with very little success, according to the report, titled 'Face Off: The lawless growth of facial recognition in UK policing'.

It claims the Met has a failure rate of 98%, and during last year's Notting Hill Carnival, that police misidentified 95 people as criminals. The Met admitted that as a result of using facial recognition it has stored 102 innocent people's biometrics data for 30 days. Despite this, the force is planning seven more deployments this year.

"Real-time facial recognition is a dangerously authoritarian surveillance tool that could fundamentally change policing in the UK. Members of the public could be tracked, located and identified, or misidentified, everywhere they go," said Silkie Carlo, director of Big Brother Watch.

"It is deeply disturbing and undemocratic that police are using technology that is almost entirely inaccurate, that they have no legal power for, and that poses a major risk to our freedoms."

Facial recognition is also used by South Wales Police, but 91% of its system's matches were inaccurate, despite the Home Office providing 2.6 million in funding to use the technology.

The South Wales police not only misidentified 2,400 innocent people with facial recognition, it also stored these people's biometric data, without their knowledge, for a year.

"This has wasted millions in public money and the cost to our civil liberties is to high. It must be dropped," added Carlo.

The campaign has been backed by a number of rights and race equality groups, such as Article 19, Index on Censorship, Liberty, Netpol and the Race Equality Foundation. Shadow home secretary Diane Abbott and shadow policing minister Louise Haigh will speak about the campaign in Parliament this afternoon.
