How do SecuGens fingerprint recognition products work?
Basic functions for a fingerprint biometric system include fingerprint imaging, extraction and matching. SecuGen provides both hardware and software components for these functions as well as additional features and tools. Fingerprint Imaging: A user must first enroll his or her fingerprint and will be prompted to scan one or more fingers with the SecuGen fingerprint reader. The reader captures fingerprint images and sends them to a computer for processing. Fingerprint Extraction: SecuGen’s fingerprint template extraction algorithm (or “template generator”) analyzes and extracts minutiae points from the images and converts the minutiae data into a unique mathematical template, comparable to a 60 digit password. This unique template is then encrypted for security and stored with other identifying information about the user. No actual image of the fingerprint is stored but is discarded after extraction. Fingerprint Matching for Verification: The enrolled user states his or her identity (f
