Met Police to deploy facial recognition cameras

The Metropolitan Police has announced it will use live facial recognition cameras operationally for the first time on London streets.
 
The cameras will be in use for five to six hours at a time, with bespoke lists of suspects wanted for serious and violent crimes drawn up each time.
 
Police say the cameras identified 70% of suspects but an independent review found much lower accuracy.
 
Privacy campaigners said it was a "serious threat to civil liberties".
 
Following earlier pilots in London and deployments by South Wales Police, the cameras are due to be put into action within a month.
 
Police say they will warn local communities and consult with them in advance.
 
Cameras will be clearly signposted, covering a "small, targeted area", and police officers will hand out leaflets about the facial recognition scanning, the Met said.
 
Assistant Commissioner Nick Ephgrave said the Met has "a duty" to use new technologies to keep people safe, adding that research showed the public supported the move.
 
"We all want to live and work in a city which is safe: the public rightly expect us to use widely available technology to stop criminals," he said.
 
"Equally I have to be sure that we have the right safeguards and transparency in place to ensure that we protect people's privacy and human rights. I believe our careful and considered deployment of live facial recognition strikes that balance."
 
Mr Ephgrave said the system could also be used to find missing children or vulnerable adults.
 
Trials of the cameras have already taken place on 10 occasions in locations such as Stratford's Westfield shopping centre and the West End of London.
 
The Met said it tested the system during these trials using police staff whose images were stored in the database. The results suggested that 70% of wanted suspects would be identified walking past the cameras, while only one in 1,000 people generated a false alert.
 
But an independent review of six of these deployments, using different methodology, found that only eight out of 42 matches were "verifiably correct".
 
Campaigners have warned that accuracy may be worse for black and minority ethnic people, because the software is trained on predominantly white faces.
 
Over the past four years, as the Met has trialled facial recognition, opposition to its use has intensified, led in the UK by campaign groups Liberty and Big Brother Watch.
 
They exploited a nervousness on the part of senior police officers to speak out in favour of the technology at a time when the government was preoccupied with other matters.
 
But testing and work on the system has continued and now, after the election of a Boris Johnson-led administration whose party promised in its manifesto to "empower the police to safely use new technologies", Scotland Yard has made its move.
 
The force also believes a recent High Court judgment, which said South Wales Police did not breach the rights of a man whose face had been scanned by a camera, gives it some legal cover.
 
The case is heading for the Court of Appeal. But the Met is pressing on, convinced that the public at large will support its efforts to use facial recognition to track down serious offenders - even if civil liberties campaigners do not.
