[edit] Introduction
Biometric identification
Is used to verify a person’s identity by digitally measuring of fixed traits and comparing later these measures with some measures from the same person kept in a file in some data base. With today’s technologies becoming faster and more precise everyday, there is a need in the biometric field for new devices that are ever more accurate, cost effective, and simple in their implementation. Below is a list of the major biometric technologies that are available today and ones that may be available in the future. www.oap1.com/sig.htm)/>(www.biometricscatalog.org)/
DNA Identification
DNA is often called the code of life and is known to be totally unique for each person. Perhaps is the most precise system of identification known .The one of the most popular methods of taking DNA is by taking blood samples.One of its biggest problems is that if a nationwide network of DNA is made, therenight be only a couple steps until everyone’s biological flaws are revealed. This is a major invasion of privacy and might prove to be the downfall of DNA testing.
Finger/Thumb Print Identification
This is the most widely used biometric technology and is well known for its affiliation with the law enforcement and the world of entertainment. This technology is very reliable and accurate, and has been backed up by many studies that verify that fingerprints are indeed unique. Fingerprints are not stored by picture but by measurements of the distances between the ridges and loops of the thumbprint.
Retina Scan
Retina scans have become very popular with corporations whom use biometrics because of the accuracy and speed in which they can be implemented. Retina scans test the pattern of blood vessels lining the retina of the individual human eye. Another bonus of retina scans is that they are not revealed to the casual observer, and we do not leave behind traces of its detail as we might fingerprints or DNA. (www.cs.indiana.edu)
