NIST advancing contactless fingerprint biometric technology with test fingers

To improve the accuracy of the emerging contactless fingerprint reader technology, researchers with the U.S. National Institute of Standards and Technology (NIST) have developed a new way of comparing the images captured through contact versus contactless processes — by creating standardized test fingers.

While traditional fingerprint devices capture 2D images, contactless fingerprint readers are designed to capture the three-dimensional characteristics of fingerprints, including ridges and valleys. To test the accuracy of this new technology, NIST researchers have created …
