Summary of NIST Patriot Act Recommendations

1. One-to-One Matching (Verification) -NIST recommends one face and two index fingerprints for verification. All three biometrics should be in image form. The face image should conform to the ANSI/INCITS 385-2004 standard. The fingerprint images should conform to the ANSI/INCITS 381-2004 standard with 500 dots per inch (dpi) scan resolution. 2. One-to-Many Matching (Identification) -NIST recommends ten slap fingerprint images stored in type 14 ANSI/NIST-ITL 1-2000 formatted records for enrollment and checking of large databases. Face images are not recommended for identification applications. With available fingerprint scanning technology, the acquisition of 10 slap fingerprints should take only slightly more time than the acquisition of two flat fingerprints.
