III – Introduction to Fingerprint Recognition
Technology
Prior to operating the F707/708 it is essential to first understand how
fingerprint recognition technology works.
Adding and verifying fingerprints is the core function of the
F707/708. Once a thorough understanding of fingerprint
recognition technology is obtained, you’ll find your experience with
the F707/708 to be very productive and rewarding.
How fingerprint recognition technology
works
When the user places his/her finger on a Fingerprint Recognition Device
(i.e. F707/708) for the first time, the fingerprint is scanned and converted
into a computer-generated “biometric template”. The templates can only
be recognized by each respective biometric manufacturers’ devices. Also
note that these “templates” are NOT actual fingerprint images. “Real”
fingerprint images cannot be re-generated from these templates.
All fingerprints contain a number of unique physical characteristics called
minutiae. Minutia include certain visible aspects of fingerprints such as
ridges, ridge endings, and bifurcation (forking) of ridges. Most of the
minutiae are found in the core points of fingerprints, and the core points
themselves are found near the center of the fingerprint on the fleshy pad of
the finger.
