NIST Special Database 30 is being distributed for use in development and testing fingerprint matching systems. This fingerprint database offers the user complete paired fingerprint cards that include all ten rolled fingerprints and the plain/flat impressions at the bottom of the card. Paired fingerprint cards are two sets of fingerprints for one individual captured at different dates. By including all the fingerprint data for the card pairs, a user can compare any combination of plain and rolled images. This database has 216 paired fingerprint cards. Each card is scanned at 39.4 pixels per mm (1000 ppi) and segmented into individual fingerprint images. The segmented images are in PNG format. Reference information is included in a metadata text file.
This fingerprint data is available in two resolutions. Special Database 30 images are 1000 ppi and Special Database 29 images are 500 ppi.
