Cognaxon has released NIST viewer which reads NIST (ANSI/NIST-ITL
1-2000) file format.
The advantage of NIST files is the ability to contain multiple images
and other types of data about the person in one single file, which
simplifies biometric data exchange between participating parties.
As for example: one WSQ file contains only one fingerprint image, but
one NIST file contains inside many fingerprint images and also other
information.
ANSI/NIST-ITL 1-2000 is Data Format for the Interchange of
Fingerprint, Facial, & Scar Mark & Tattoo (SMT) Information defined by
American National Standard for Information Systems.
One single NIST (ANSI/NIST-ITL 1-2000) file is able to contain
following types of data:
Type-1 Transaction Information
Type-2 Descriptive Text (User-defined)
Type-3 Fingerprint Image Data (Low-resolution grayscale)
Type-4 Fingerprint Image Data (High-resolution grayscale)
Type-5 Fingerprint Image Data (Low-resolution)
Type-6 Fingerprint Image Data (High-resolution)
Type-7 Image Data (User-defined)
Type-8 Signature Image Data
Type-9 Minutiae Data
Type-10 Facial & SMT Image Data
Type-11 Reserved for Future Use
Type-12 Reserved for Future Use
Type-13 Latent Image Data (Variable-resolution)
Type-14 Tenprint fingerprint Impressions (Variable-resolution)
Type-15 Palmprint Image Data (Variable-resolution)
Type-16 User-defined Testing Image Data (Variable-resolution)
