Fingerprint matching is the process used to determine whether two sets of fingerprint ridge detail come from the same finger.
Introduction
Extensive research has been done on fingerprints in humans.
Two of the fundamentally important conclusions that have risen from research are:
(1) a person's fingerprint will not naturally change structure after about one year after birth and
(2) the fingerprints of individuals are unique.
Even the fingerprints in twins are not the same. In practice two
humans with the same fingerprint have never been found
Introduction
A fingerprint is comprised of ridges and valleys.
The ridges are the dark area of the fingerprint and the valleys are the white area that exists between the ridges.
These points are also known as the minutiae of the fingerprint. The most commonly used minutiae in current fingerprint recognition technologies are ridge endings and bifurcations because they can be easily detected by only looking at points that surround them.
