North Wales Police are conducting a two-day pilot program using live facial recognition technology at Holyhead Port. The technology aims to identify individuals wanted for “priority offenses”, those with outstanding warrants, and missing persons.
“The specific purpose for live facial recognition deployment is to support policing in the identification of persons wanted for priority offences, to support law enforcement including the administration of justice (through arrest of persons wanted on warrant or unlawfully at large/ recall to prison), and to promote safeguarding of vulnerable persons,” said a North Wales Police spokesperson.
The system operates by comparing faces captured by cameras against watchlists containing images of wanted or missing individuals. While this technology has proven effective in aiding law enforcement, concerns regarding privacy and data storage have been raised by privacy advocates.
North Wales Police emphasized that the biometric data of individuals not generating an alert through the facial recognition system will be immediately and automatically deleted, with images triggering an alert deleted within 24 hours. The department also clarified that CCTV footage used by the technology will be securely stored for 31 days.
The police department acknowledged past concerns regarding bias in facial recognition technology, but pointed to advancements in algorithmic fairness and a report from South Wales Police, the Met, and the National Physics Laboratory, supporting the accuracy and lack of statistical bias in their chosen algorithm settings.
Finally, North Wales Police emphasized that biometric data will not be shared with third parties, and that the database used for facial recognition comparisons comprises images lawfully held by the police.
