The following sections outline the main biometrics standards bod ies, discuss some specific standards, and describe some of the challenges facing the processes. As with standards in other technologies, biometric standards face tension between being flexible enough to enable innova tion while sufficiently prescriptive and detailed to allow interoperability and useful comparison of technologies and their capabilities.

Nationally, the American National Standards Institute (ANSI) coordinates voluntary standardization and conformity assessments in the United States, approves the creation of all national and international standards, and may also implement any changes to the standards as well.

This standard is officially titled Information Technology: American National Standard for Information Systems -- Data Format for the Interchange of Fingerprint, Facial, & Other Biometric Information -- Part NIST Special Publication 00 ANSI/NIST-ITL -00. That standard has recently been updated to XML format to reflect the emerging needs of the defense and intelligence communities and defines about 20 record types for use in exchanging biometric information (faces, fingers, palms, latent prints, and irises)

NIST developed an automated tool to rate the quality of fingerprint images. In October 2004 NIST released an updated version of this suite of tools for handling digital fingerprint images.

While the standard as written permits the exchange of minutiae in lieu of images, the minutiae defined in the standard are not as useful for processing across different vendor environments, from an algorithmic perspective, as permitting a vendor to receive an image and extract their proprietary minutiae set.5 The ANSI/NIST standard currently supports at least eight vendor minutiae sets, per Table 15 of the standard. The reasons for the push in this direction are twofold.

Best practices performance testing measures the performance of the underlying biometric matchers for fingerprints, palm prints, and latent impressions, with fingerprint personnel permitted to perform quality control steps such as sequence correction and editing of low-quality images. Another trend in benchmarking large-scale matcher systems that will be servicing larger systems is to bring the algorithms in house and run them under very controlled conditions against millions of records.

From page 165... ...
NIST, for example, has conducted performance tests at a level that surpasses the standards that have been estab lished by the international standards body. Two tests that have included additional criteria by NIST include the facial recognition challenge 2006 test and the MINEX 2006 test, which aim to enable interoperability of fingerprints at the minutiae level.
