How facial recognition technology aids police

Police officers’ ability to recognize and locate individuals with a history of committing crime is vital to their work. In fact, it is so important that officers believe possessing it is fundamental to the craft of effective street policing, crime prevention and investigation. However, with the total police workforce falling by almost 20 percent since 2010 and recorded crime rising, police forces are turning to new technological solutions to help enhance their capability and capacity to monitor and track individuals about whom they have concerns.

One such technology is Automated Facial Recognition (known as AFR). This works by analyzing key facial features, generating a mathematical representation of them, and then comparing them against known faces in a database, to determine possible matches. While a number of UK and international police forces have been enthusiastically exploring the potential of AFR, some groups have spoken about its legal and ethical status. They are concerned that the technology significantly extends the reach and depth of surveillance by the state.

Until now, however, there has been no robust evidence about what AFR systems can and cannot deliver for policing. Although AFR has become increasingly familiar to the public through its use at airports to help manage passport checks, the environment in such settings is quite controlled. Applying similar procedures to street policing is far more complex. Individuals on the street will be moving and may not look directly towards the camera. Levels of lighting change, too, and the system will have to cope with the vagaries of the British weather.

As with all innovative policing technologies there are important legal and ethical concerns and issues that still need to be considered. But in order for these to be meaningfully debated and assessed by citizens, regulators and law-makers, we need a detailed understanding of precisely what the technology can realistically accomplish. Sound evidence, rather than references to science fiction technology --- as seen in films such as Minority Report --- is essential.

With this in mind, one of our conclusions is that in terms of describing how AFR is being applied in policing currently, it is more accurate to think of it as “assisted facial recognition, ” as opposed to a fully automated system. Unlike border control functions -- where the facial recognition is more of an automated system -- when supporting street policing, the algorithm is not deciding whether there is a match between a person and what is stored in the database. Rather, the system makes suggestions to a police operator about possible similarities. It is then down to the operator to confirm or refute them.

What is Interpol?

Founded in 1923, Interpol is an international police organisation made up of 194 member countries. It is not a police force in the traditional sense – its agents are not able to arrest criminals. Instead, it is more of an informationsharing network, providing a way for national police forces to co-operate effectively and tackle international crime ranging from human trafficking and terrorism to money laundering and illegal art dealing.

The organisation, based in France, operates centralised criminal databases that contain fingerprint records, DNA samples and stolen documents: a treasure trove so valuable that police consulted it 146 times every second in 2017. Interpol’s other main function is to issue notices: alerts to member states for missing or wanted persons. The bestknown of these is the “Red Notice”, a notification that a member state would like someone arrested. States are not obliged to follow these notices, but will often treat them as a warrant for someone’s arrest and extradition. “Diffusions”, which can be issued with less bureaucracy, are another popular way of seeking arrests through Interpol.

Notices and diffusions lie at the heart of the organisation’s recent turmoil. Though Interpol’s constitution explicitly forbids any activities of a political character, activists accuse it of failing to enforce this rule.
