Use of facial recognition by UK police


Use of facial recognition by UK police

The facial recognition system used by the UK’s largest police force is “very accurate” but when live facial recognition is used at lower face-match thresholds, a slight difference in performance between some demographics was observed.

This testing was performed by the UK National Physical Laboratory (NPL). Officials at NLP further stated that “We find that, if the system is run at low and easy thresholds, the system starts showing a bias against Black males and females combined.”

The NEC system, used by the Metropolitan Police Service for policing, has become a subject of controversy with rights groups raising concerns about false positives and discrimination.
