Accuracy requirements. The matcher accuracy will vary as a function of the class of service (identification, forensic, and tactical) and the quality of the input images. Identification service accuracy requirements are typically higher than those for forensic services as the input images are typically of better quality for live scan enrollments than for latent lifts. • Accuracy terms-of-art have been undergoing an evolutionary change for the past few years. While reliability, true accept rate, false reject rate, and other terms are often used for access control systems and other biometric modalities (such as facial recognition), a consensus has developed in the international standards community around the terms true match rate and failure to match rate when discussing friction ridge matching on a large-scale. • For this project, accuracy will have four accuracy terms: DocuSign Envelope ID: 46E92DE6-41 F7-4244-8F8A-51 C8B2BE0792 Attachment A using the selectivity numbers in the table below.
