NIST’s fingerprint dataset SD 302 includes 10,000 fingerprint images, including this one from the sticky side of a postage stamp. The dataset is now completely annotated with details such as the colorized regions at right. The colors, which represent regions of differing quality, will help train both humans and machine learning algorithms how to distinguish identifying features and weigh their importance as evidence.Credit: B.

Abstract
National Institute of Standards and Technology (NIST) Special Database 302 contains 10000 latent impression distal phalanx images. This collection of data came from the Intelligence Advanced Research Projects Activity’s Nail to Nail Fingerprint Challenge. NIST worked with Certified Latent Print Examiners to annotate these images with features (e.g., minutiae, orientation, ridge quality maps) and determine their ground truth finger positions. The fully-annotated collection of data is made freely available for research purposes.
