Evaluating the Use of Automated Facial Recognition Technology in Major Policing Operations

The project by the Universities' Police Science Institute evaluated South Wales Police's deployment of Automated Facial Recognition across several major sporting and entertainment events in Cardiff city over more than a year, including the UEFA Champion's League Final and the Autumn Rugby Internationals. The study found that while AFR can enable police to identify persons of interest and suspects where they would probably not otherwise have been able to do so, considerable investment and changes to police operating procedures are required to generate consistent results. Researchers employed a number of research methods to develop a rich picture and systematically evaluate the use of AFR by police across multiple operational settings. This is important as previous research on the use of AFR technologies has tended to be conducted in controlled conditions. Using it on the streets and to support ongoing criminal investigations introduces a range of factors impacting the effectiveness of AFR in supporting police work. The technology works in two modes: Locate is the live, real-time application that scans faces within CCTV feeds in an area. It searches for possible matches against a pre-selected database of facial images of individuals deemed to be persons of interest by the police.
