Hands Off! NIST Helps Bring Contactless Fingerprint Technology to Market

Quickly relocating by confidence checkpoints by display your palm to a scanner seems true out of scholarship fiction, though a National Institute of Standards and Technology (NIST) is operative with attention to move fast, touchless fingerprint readers out of a lab and into a marketplace.


The touchless record offers rare speed and a sterilizing choice to required fingerprint readers. But before a contactless fingerprint record can be used broadly, a products contingency be evaluated and proven to work with millions of existent contact-based fingerprint records.

Enter NIST.

When it comes to biometrics—including fingerprints—the U.S. supervision relies on NIST to rise information format standards, best practices and methods for acceptance contrariety and to denote a new product’s ability to work with existent technology.

NIST conducts a investigate on contactless fingerprinting inclination with a Federal Bureau of Investigation Biometric Center of Excellence. The partnership’s idea is to rise common requirements, metrics and open contrariety methods for this new fingerprint record that will support destiny acceptance for squeeze on a Government Certified Products lists.

Researchers during NIST are operative with contactless fingerprint inclination from MorphoTrak, LLC, and 3M Company by Cooperative Research and Development Agreements (CRADAs). NIST continues to find new CRADA partners.

“The largest plea we are confronting is that this new record produces images that are essentially opposite than existent images,” says Michael Garris, NIST biometrics comparison scientist.

Because skin is elastic, normal fingerprints enclose healthy exaggeration from a vigour of fixation a finger on a fingerprinting surface, Garris explains. Contactless fingerprints are vigour giveaway and will demeanour different.

There are also many forms of sensors being used for contactless fingerprint capture. They are significantly opposite from a sensors used to obtain contact-based fingerprints, so a touchless scans have opposite picture properties.

“It is really formidable for NIST or record developers to residence these issues independently,” explains Garris. “The CRADA provides a infallible sourroundings for attention to come together and plainly work with NIST.”

NIST is building methods, metrics and targets to exam these inclination to establish if they are reliable, accurate and can work with bequest systems. The initial step is to rise models to magnitude picture fealty on a new systems, including building calibration patterns that can be used as visual targets to establish resolution, focus, contrast, spatial coherence and other properties of fingerprints.

The researchers also are questioning materials for use as fake targets for testing, such as aluminum, polycarbonate and NIST-developed materials that can impersonate a pigmentation and light-diffusion properties of tellurian tissue.
