Matching Performance for the US-Visit IDENT System Using Flat Fingerprints



Charles L. Wilson, Michael D. Garris, Craig I. Watson


This report discusses the flat to flat matching performance of the US-VISIT fingerprint matching system. Both one-to-many matching used to detect duplicate visa enrollments and one-to-one matching used to verify the identity of the visa holder are discussed. With the proper selection of an operating point, the one-to-many accuracy for a two-finger comparison against database of 6,000,000 subjects is 95% with a false match rate of 0.08%. Using two fingers, the one-to-one matching accuracy is 99.5% with a false accept rate of 0.1%.
