The source of the term biometric comes from two distinct Greek words”Bio” which means life and”Metrics” which means to measure. Since the ancient times, humans recognized each other through facial recognition, we keep the faces of people we meet in our memory and upon seeing them again; we greet them. This is a pure biometric which each and every individual has within them; it is a predominant behavior pattern where we can recognize other individuals by face, bodily structure or their voice somewhat unconsciously. Even thumbprints are used at different places as a kind of signature especially by those who can’t read or write, this is because each thumbprint is unique to its owner. Even in times that date back to as far as the Babylonian age, fingerprints were used for business transactions.
Fast forward to several years after, seeing cool gadgets was just restricted to big budget science fiction movies and we were mesmerized and fascinated with them. Machines scanning retina and fingerprints or even those that served on voice recognition were stuff that just featured in James Bond films and nobody ever thought they would get to witness and utilize such technologies in their everyday life. All of it sounded like some magic stuff of a faraway land but soon it all took the form of a reality.
The first biometric device was devised by Sir William Herschel who recorded a handprint on the back of a contract for every employee in order to know who were his workers and who were the outsiders claiming to be in his job during payday. This was the first time that finger and hand images were captured for the purpose of identification. This step proved to be a benchmark concerning safety management, during the years steps were taken steadily for further advancement of these devices. Algorithms were created for Finger picture and facial quality measurement and an iris excellent measurement algorithm was also developed by the U.S government in 2008. The C.I.A even used facial recognition technology in order to recognize the dead body of Osama Bin Laden.
The current era has witnessed a boom in the development and application of Biometric security devices, from banks to work place and even faculty and schools have started to use this advanced and far more reliable form of security. Seems like the prevalence and usage of biometric will only grow a whole lot farther in the future.
