The field of IT security has been working with biometrics for quite sometime and has successfully added a layer of security for computer users out there. The heaviest users of such technology are large businesses who aim to have the need for protection due to technology breakthroughs, corporate information and other vital security issues such as in government military offices. Though the technology has spanned most of the human physiology ( Fingerprint, cornea scanning, palm scanning, face recognition and many others) none have focused much on the area of speech or voice recognition technology. Your voice is as unique as a fingerprint and even between twins there are subtle differences in their make-up, tone, pitch, and many other voice characteristics are being studied in conjunction with other biometrics technologies for access control to data sensitive areas such as government intelligence offices, tax office and other such areas that need protection. With many people using headsets and other devices, why not voice recognition. Even walking patterns are being studied by analysts in Sweden which have been working on security devices for cellular phones which can detect if the user has changed and shuts itself down preventing use. This is done to discourage theft of cellular devices which has seen a sudden rise in the past years. The voice recognition can replace password which, as todayâ€™s technology sees it is quite inefficient. Other technologies of the future may have your DNA as your password which has been highlighted by sci-fi movies such as the Minority Report where retinal scanning was used to identify people. The Futuristic world of Gattaca where people are selected for their genes rather than personality and abilities. The future of biometrics is indeed heading that way for the ultimate identification system is your DNA which is unique in all aspects to each and every individual.
