Citation Guidance: A 1:N search of an applicant's collected biometric characteristics against a database is done to determine whether the applicant is already present in the database, possibly under a different name. The false positive identification rate (FPIR) refers to the proportion of 1:N searches in which a biometric system incorrectly identifies another person as a match, which is a false positive result. The performance metric of 1:1,000 means that a false positive outcome occurs for no more than 1 in every 1,000 searches. Tests that demonstrate this requirement SHALL employ a gallery no smaller than 90% of the current or intended operational size (N).
