False Acceptance Rate (FAR): A measure used in biometric security systems to indicate the probability that the system will incorrectly accept an unauthorized user. It is one of the key metrics, along with the False Rejection Rate (FRR), used to assess the performance of a biometric system. A low FAR is desired as it reflects a higher level of security, indicating that the system is less likely to permit access to an unauthorized individual. However, system designers must balance FAR with FRR to ensure the system is both secure and user-friendly.
