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.

À proporção que alguns locatários abandonavam a estalagem, muitos pretendentes surgiam disputando os cômodos desalugados. Delporto e Pompeo foram varridos pela febre amarela e três outros italianos estiveram em risco de vida. O número dos hóspedes crescia, os casulos subdividiam-se em cubículos do tamanho de sepulturas, e as mulheres iam despejando crianças com uma regularidade de gado procriador. Uma família, composta de mãe viúva e cinco filhas solteiras, das quais destas a mais velha tinha trinta anos e a mais moça quinze, veio ocupar a casa que Dona Isabel esvaziou poucos dias depois do casamento de Pombinha.

Agora, na mesma rua, germinava outro cortiço ali perto, o “Cabeça-de-Gato”. Figurava como seu dono um português que também tinha venda, mas o legítimo proprietário era um abastado conselheiro, homem de gravata lavada, a quem não convinha, por decoro social, aparecer em semelhante gênero de especulações. E João Romão, estalando de raiva, viu que aquela nova república da miséria prometia ir adiante e ameaçava fazer-lhe à sua perigosa concorrência. Pôs-se logo em campo, disposto à luta, e começou a perseguir o rival por todos os modos, peitando fiscais e guardas municipais, para que o não deixassem respirar um instante com multas e exigências vexatórias; enquanto pela sorrelfa* plantava no espírito dos seus inquilinos um verdadeiro ódio de partido, que os incompatibilizava com a gente do “Cabeça-de-Gato”. Aquele que não estivesse disposto a isso ia direitinho para a rua, “que ali se não admitiam meias medidas a tal respeito! Ah! ou bem peixe ou bem carne! Nada de embrulho!”.
