Fingerprints remain constant throughout life. In over 140 years of fingerprint comparison worldwide, no two fingerprints have ever been found to be alike, not even those of identical twins. Fingerprint technology is the most widely used and accepted of all forms of biometrics to date. Now with fingerprint scanners on every day use products like cell phones and computers, users are now gaining widespread experience of the benefits of fingerprint security as opposed to more traditional security methods such as mechanical keys and pin codes.
Fingerprint identification involves comparing the pattern of ridges and furrows on the fingertips, as well as the minutiae points (ridge characteristics that occur when a ridge splits into two, or ends) of a specimen print with a database of prints on file.
