biometricsbiometry is a branch of biology that studies biological phenomena and observations by office of statistical analysis (Dictionary.com WordNet 2.0, 2003 Princeton University). In other words Biometrics is the drive of the human system natural identification, now a days corporations practice session biometrics instead of a simple code. Also police and other federal and worldwide associations affair biometrics to stop lamentables and to keep shack of where criminals are and who they really are. Biometrics has been around for hundreds upon hundreds of years, from when the Chinese first employ it to identify children with footprints, to the to a greater extent advanced salinity recognition that has been developed for today. The use of Biometrics and the technologies that have come from it has made security much more advanced, but its getting to the point that maybe even the engineering science of Biometrics is intruding our privacy.One of the first known cases of h umans use biometrics to identify star another was by early Chinese merchants. Joao Barros, wrote that the Chinese merchants employ the first noted form of biometrics by stamping childrens palm and footprints on paper with ink. By doing this, the Chinese solve a way to tell apart young children from one another.

He realized that even if a criminal changed his name, cut his hair or put on weight, certain elements of the consistence wouldnt change. This led him to form a method of measuring the more noticeable parts of a mortals body, the parts of the body that never changed during their life such as the size of the skull or the continuance of their fingers. This system was called anthropometrical signalment and was very basic in its accomplishment. Whenever a person was arrested they were sent through a series of tests that recorded the length and distinct marks of their bodies. This was all recorded on a card and filed by in groups with similar test results.
