Creepy, Orwellian and un-British: PROFESSOR NOEL SHARKEY says the rash of facial recognition cameras sweeping the UK should worry us all
Surveillance cameras are filming us everywhere. We know that and we’re used to it. We also know the images won’t be analysed unless there’s been a crime – so that’s OK, isn’t it?
No it’s not. Because, as The Mail on Sunday reveals today, a number of police forces and councils have recently adopted a controversial new form of camera technology which is not accurate, reliable or trustworthy.
Professor Noel Sharkey (pictured on March 21, 2019) discovered how falliable facial recogntion cameras are after attending last year’s Swansea air show
At the heart of this development is something called live facial recognition (LFR), software which can automatically recognise a face in a crowd within a fraction of a second. And this means we can be monitored everywhere we go, no matter who we are with or what we are doing.
Facial recognition could strike at the very core of our free society. Yet – without any public consultation – British police forces are introducing LFR as quickly as they can. It’s as if we’re standing in a perpetual identity parade without ever being told, let alone asked.
Needless to say, the dangers are huge and I have witnessed them first-hand. The South Wales police force has been testing facial recognition for a couple of years and, at the invitation of the Chief Constable, I attended a trial at last year’s Swansea air show.
The Orwellian surveillance of facial recognition cameras (pictured at Cardiff City Championship) is worryingly inaccurate. A Big Brother Watch think-tank showed they are correct in only five per cent of cases at best
What I saw was concerning, and not just because I object to the slippery introduction of Orwellian surveillance. For when I saw the technology up close, I could also see how fallible it is.
Hidden some distance away, I watched as individuals at the air show walked past an LFR camera and the computer studied each face, taking just 0.2 seconds per individual. In that time, it generated a ‘face print’ and compared it with mugshots of known criminals.
I witnessed how the computer flagged what the policeman beside me described as a ‘wrong ’un’ and how the individual’s face then flashed up alongside the corresponding criminal face.

Ten seconds later, however, and after human intervention, it was decided it wasn’t a match after all. The human eye had picked up minor differences in the hairlines of the men in the two photographs – a very necessary check.
Yet, with the rapid pace of technological advancement, it seems to me inevitable human beings will eventually be removed from the process altogether. And what then?
An investigation by the Big Brother Watch think-tank has shown LFR results are worryingly inaccurate with the computer correct, at best, in only five per cent of cases. Accuracy fell to two per cent in a trial at the Notting Hill carnival. It seems that LFR has particular trouble when it comes to people who have darker shades of skin.
More favourable results emerged from an Essex University review of the Metropolitan Police trials, in which the computer was found to have been accurate in 18 per cent of the individuals it ‘recognised’. This is still an astonishingly low figure, however.
Why, then, is the Met announcing the ‘successful’ completion of its trials? And why is it installing LFR across the capital? The police should look to America, where the technology is already taking hold, to see how misguided a decision this is.
When the American Civil Liberties Union (ACLU) ran photographs of members of Congress through US police software, the computer identified 28 of them as criminals. Wrongly, of course. And the people it picked out were mostly from African and Latino backgrounds.
A computer scientist at the Massachusetts Institute of Technology, Joy Buolamwini, experimented with the most commonly used facial recognition systems to find out how good they were at matching a photograph to a face stored in a memory bank. The worst results were for women with dark skin. IBM’s system, for example, failed 31 per cent of the time.
Ms Buolamwini, who is Ghanaian-American, began the research after discovering that LFR couldn’t even locate her face – let alone identify her features – unless she wore a white mask. LFR is biased both in terms of race and gender. Then we must ask about the cost to our liberty, and the troubling example set by China, where the Communist leadership uses LFR to great effect. When citizens buy a smartphone, they are photographed for use with LFR, which means they can be tracked by the ubiquitous surveillance cameras.

It is used much like our number-plate recognition software, and the result is that you can get an automatic fine for antisocial behaviour. It has been used to publicly shame people who go outside in their pyjamas. And, bizarrely, public lavatories are being fitted with LFR to set a limit on the amount of toilet paper that those in need can take.
The omnipresent technology is used in Xinjiang province as an aid to repress the Uighur Muslim population. The computer keeps records of their comings and goings and can be connected to other apps that alert police if more than five Uighurs collect together. Many end up in re-education camps.
China is close to becoming the ultimate surveillance state, but Russia is at it too, with LFR applied to the vast Moscow CCTV network.
It is all too easy to assume that, because we are a democracy, such intensive surveillance would not be tolerated in Britain. But we have seen how quickly civil liberties can be ignored in the case of, say, major terror attacks. In the past few weeks, in fact, Sir Andrew Parker, head of MI5, spoke of the ‘need’ for our intelligence services ‘to be able to make sense of the data lives of thousands of people in as near to real time as we can get to’.
The Mail on Sunday’s revelation gives me grave cause for concern because it means that to ID people not already on the police offenders’ lists requires records of the faces of all of us. And where do those come from? Enter the private companies who are always ready to help with large data banks of facial portraits and accompanying technology.
We know that big tech companies such as Facebook retain photographs of us, but even small start-ups are getting in on the act.
For example, the firm Clearview has scraped the images of more than three billion faces from internet sites and is selling these along with its technology to law-enforcement agencies and other companies.
Wild West of tech: There is sparse regulation into LFR and what we do have is ignored with impunity. The government must introduce laws to ensure the technology (pictured) is contained
It’s too early to tell what injustices this may bring in the future, but we can be confident there is a breathtaking arrogance to it all.
It emerged last year, for example, that a number of private shopping centres including Sheffield’s Meadowhall, the Trafford Centre in Manchester and the area around London’s King’s Cross had been trying out LFR without telling any of us.
They were mainly looking for shoplifters or antisocial behaviour. But if a shopkeeper felt someone had behaved suspiciously, they could put that individual’s picture on a watch list that was shared with all of the other shops.
The suspect had no idea they were on the list and no recourse to justice. That is plain wrong.
As Information Commissioner Elizabeth Denham put it recently, LFR is a ‘step change in policing techniques; never before have we seen technologies with the potential for such widespread invasiveness’.
When it comes to LFR, we are in the Wild West. There is sparse regulation and what we do have is ignored with impunity. It won’t be easy to put this genie back in the bottle but we must try – and try again until we succeed.
Our Government must immediately limit the scope of LFR to serious offences. We need strong laws to ensure that this horrific technology is contained.
