Biometrics is described as the use of human physical features to verify identity and has been in use since the beginning of recorded history. Only recently, biometrics has been used in today’s high-tech society for the prevention of identity theft. In this paper, we will be understanding biometrics, exploring the history of biometrics, examples of today’s current technology and where biometrics are expected to go in the future.
By definition, “biometrics” (Woodward, Orlans, and Higgins, 2003) is the science of using biological properties to identify individuals; for example, fingerprints, retina scans, and voice recognition. We’ve all seen in the movies, how the heroes and the villains have used other’s fingerprints and

Consider this, the odds of one finding two matching irises is 1 in 1078 and the human population is calculated at 1010. In addition, the iris will not change over a person’s lifetime and is not readily subject to wear and injury. This makes the retinal scanning the premier in external biometric identification.
The latest and greatest biometric identifier is DNA (deoxyribonucleic acid). Currently, using DNA as an identifier is not a quick process but is a very precise process. The goal of technology is to advance DNA processing to point it will rival the processing time of a fingerprint. DNA technology is used heavily for “after the fact” identification such as legal cases involving murders, sexual assaults, child support, etc. After another decade or so, DNA technology may have progressed to the point where it can be used to prevent access to secured areas or to protect from credit card theft.
The future of biometric identification is a very fascinating world. Companies are developing technologies to positively identify humans through ear shapes, body odor, and body salinity. As technology and computer process power increases, new identification methods will become available and older methods will only get faster. The main drive for advancement of biometric identification is the falling cost of equipment to perform the
