False-Match Rate (FMR)

FRT & privacy

The FRT performance metric measuring how often the system incorrectly flags a non-watchlist person as a match. High FMR creates false-positive harm (wrongful refusal of entry, embarrassment, escalation to confrontation). Vendor selection should require published FMR figures and the threshold setting that produces them; in-venue tuning of the match threshold trades FMR against FNMR.

This term sits in the FRT & privacy section of the working glossary — vocabulary covering facial-recognition controls and the Privacy Act 1988 (Cth), including the Australian Privacy Principles and the Notifiable Data Breaches scheme.
