Research investigates use of Live Facial Recognition in Met

Rate) was 0.017 per cent. The chance of a false match therefore, is 1 in 6000 people walking past the camera.

When used at a threshold setting of 0.6 or above, any differences in matches across groups were not statistically significant - meaning performance was the same across race and gender.

With regards to Retrospective Facial Recognition, the true positive identification rate for high quality images was 100 per cent.

Independent research into the Met’s deployment of facial recognition has been published by The National Physical Laboratory.

The study, which was entitled ‘Facial Recognition Technology in Law Enforcement’, tested the accuracy, in operational conditions, of the algorithm used by the Met in terms of different demographics.

AVIATION Second UK airport scraps liquid rule

London City Airport has become the second airport in the UK to scrap the 100 ml rule for liquids with the introduction of high-tech scanners.

Flyers are now able to carry up to two litres of liquid, and liquids no longer need to be put in separate bags.

The new C3 scanners take highresolution 3D images of bags and the government has set a deadline of June 2024 for most UK airports to install the machines.

Teesside airport introduced the scanners in March.

Travellers also no longer need to remove electronics from luggage. According to chief operating officer Alison FitzGerald, the new system is quicker and safe at the same time.

The research found that there are settings the algorithm can be operated at where there is no statistical significance between demographic performance.

It was also found that when used at a threshold setting of 0.6 or above, correct matches (True Positive Identification Rate) were 89 per cent. The incorrect match rate (False Positive Identification

Terrorism

The Met says it will use “Facial Recognition Technology as a first, but significant, step towards precise community-based crime fighting.”

According to the Met: “Live Facial Recognition (LFR) enables us to be more focussed in our approach to tackle crime, including robbery and violence against women and girls.”

Increase in number of young people arrested for terrorism offences

Figures released by the home office have revealed that the number of young people being arrested on suspicion of terrorism-related offences in the UK continues to rise.

Police made 166 counter terrorism arrests in the year to 31 December 2022, of which 32 were under 17. This is an 11 per cent increase compared to the previous year.

Counter Terrorism Policing’s deputy senior national coordinator Richard Smith said: “The reality is that children and teenagers, some as young 12 or 13, are now featuring more frequently in our investigative casework.

“The statistics are stark and I know that they’re a difficult read for the public, particularly parents and carers – as police officers and investigators we absolutely share that concern.

“Our priority is always to protect the public and, at the sharpest end of the threat, individuals will be charged and prosecuted for criminal offences. However, for others, there may be different options.

“When anyone enters the counter terrorism system, we will always consider whether multi-agency interventions and safeguarding protocols will help mitigate the risk to the public. These can also work in the best interests of the individual, which is especially important when dealing with young people.

“Much like the terrorist threat, our approach is always evolving and we have a responsibility to consider all legitimate options to keep people safe.”
