Nanotechnology Biometrics in the Military A new age of Identity Authentication has arrived. Plastic ID cards, paper forms, multiple passwords and pins are being replaced with Biometrics. This science utilizes biological properties to identify individuals; for example, fingerprints, a retina scan, and voice recognition. The United States Military along with many companies have begun research and development on this emerging technology, especially after the push for a stronger national homeland security in the last 4 years. There are products already out in the market and it is slowly catching up with the consumers. As this technology gets sharper and faster, the demand is going to increase rapidly. At this stage the ideas are not yet matured, and products are emerging but they will undergo radical changes as Nanotechnology kicks in. This science of altering materials at molecular levels to create new materials is going to play a major role. Both biometrics and nanotechnology combined could create products too small to be viewed by the human eye. A human being’s entire life history could be stored in a chip smaller than a grain of sand. This type technology is under research in the military. There are also a lot
