Facial recognition

­­­­FACIAL RECOGNITION | MENRUS.CO.UKDeveloped in the 60s, facial recognition is a bit of a catch-all term for any technology that involves recognising and cataloguing human faces. The systems that make this happen are computer technologies capable of recognising and identifying an individual from a digital image/ photo or video source. The technology has come a long way since then and the reason we've included something on this website is because the police are using it, in London and elsewhere.

"Facial recognition frequently sparks two distinct fears: that it will not work well enough, or that it will work too well. The first concern highlights the fact that the technology, still in its infancy, is prone to false positives and false negatives, particularly when used with noisy imagery, such as that harvested from CCTV cameras installed years or decades ago. When that technology is used to arrest, convict or imprison people, on a possibly faulty basis, it can cause real harm. Worse, the errors are not evenly distributed; facial recognition systems have regularly been found to be inaccurate at identifying people with darker skin."

Some of the pros and cons of facial recognition

  • Pros include public security and tackling crime, fast and non-invasive identity verification (eg: passport control) and tackling banking fraud
  • Cons include data privacy concerns, erosion of civil freedoms, lack of regulation, racial bias, reliability, and cost

South Wales Police and automatic facial recognition (AFR) technology 

In an interesting (some say 'ground-breaking') development, the Court of Appeal has ruled that the use of automatic facial recognition (AFR) technology by South Wales Police is unlawful:

"The use of automatic facial recognition (AFR) technology by South Wales Police is unlawful, the Court of Appeal has ruled. It follows a legal challenge brought by civil rights group Liberty and Ed Bridges, 37, from Cardiff. But the court also found its use was proportionate interference with human rights as the benefits outweighed the impact on Mr Bridges. South Wales Police said it would not be appealing the findings."

The Metropolitan Police service for London has said this on its website:

"The Met is aware that the Court of Appeal has made its judgment regarding specific concerns raised about the use of South Wales Police facial recognition technology. The Met's approach to live facial recognition is different to the South Wales Police cases which were appealed.

This reflects our policing needs, which given the complexity of keeping London safe and the different crime issues impacting the capital, are very different from those in South Wales. Differences include that the Met has been clear that our use of this technology is intelligence-led, and focused on helping tackle serious crime, including serious violence, gun and knife crime, child sexual exploitation and helping protect the vulnerable. We tell the public about each use of facial recognition technology in advance of, during and afterwards.

We use the latest accurate algorithm and have our own tailored and carefully considered policy documents. This is reflective of the Met’s use of live facial recognition (LFR) to keep Londoners safe. We will carefully consider the judgment and act on any relevant points to ensure that we maintain our commitment to use facial recognition in a legal, ethical and proportionate way."
