Facial recognition technology, being trialled by two major police forces in Britain, should be subjected to more rigorous testing and transparency, according to new research from the University of East Anglia (UEA) and Monash University.

Facial recognition technology (FRT) involves the identification of an individual based on an analysis of the geometric features of his or her face, and a comparison between the algorithm created from the captured image and one already stored, such as from a custody image or social media account. The technology was first tested in public gatherings in 2014, when Leicestershire Police trialled a 'Neoface' facial recognition system, later using the technology to identify 'known offenders' at a music festival with 90,000 concertgoers.

The Leicestershire Police and the other two forces trialling FRT—the Metropolitan Police Service and the South Wales Police—argue the technology is lawful and its use in surveillance operations is proportionate. But researchers from UEA and Monash University in Australia say the technology could violate human rights. They argue there has not been sufficient statistical information about the trials made publically available for scrutiny. The limited outcomes that have been shared, the researchers say, have shown high false-positive identification rates and a low number of positive matches with 'known offenders'.
