Independent testing of Facial Recognition Systems (FRS) is undertaken by the National Institute of Standards & Technology (NIST) in the US. Although NIST do not test for racial accuracy bias, they do undertake testing for demographic effects.

During trials, the MPS have not used facial recognition software in isolation to determine policing operations.  When the software is used, a defined end to end process is implemented that incorporates human decision making and assessment of any matches that arise.
