NIST announced a completed set of fingerprint annotations and open-source quality-assessment software on March 23, 2026. Its Special Database 302 contains about 10,000 print images. Expert markings completed the annotations in a resource first released in 2019. [1]
The prints came from 200 consenting volunteers working in a laboratory, where they handled objects and left impressions that researchers recovered with forensic methods. Names and other identifying information were removed. That controlled collection should not be described as a sample gathered from 10,000 criminal cases. [1]
The annotations identify regions with differing amounts of usable detail, including clear ridges and smudged areas. They support training for examiners and machine-learning systems. Completing the annotations expands the training material; it does not establish an error-free method of identifying a person. [1]
The accompanying OpenLQM software adapts a tool previously restricted to U.S. law enforcement. NIST funded versions for Mac, Windows and Linux and made the software openly available. Its zero-to-100 output assesses fingerprint quality, helping prioritize examination; that number is not a probability that two prints identify the same individual. [1]
