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 store the faces of people we meet in our memory and upon seeing them again; we greet them. This is a natural biometric which each and every individual has within them; it’s a predominant behavior pattern where we could recognize other individuals by face, physical construction or their voice somewhat unconsciously. Even thumbprints are used at different places as a form of signature especially by those who cannot read or write, this is because each thumbprint is unique to its owner. In times that date back to as much as the Babylonian age, fingerprints were used for business transactions.
Fast forward to several years after, seeing cool gadgets was only limited to big budget science fiction films and we were mesmerized and fascinated with them. Machines scanning retina and fingerprints or even those that served on voice recognition were stuff that only featured in James Bond movies and no one ever thought that they would get to witness and use such technologies in their everyday life. It all sounded like some magical stuff of a faraway land but soon it took the shape of a reality. Biometric machines began to emerge in the latter half of 20th century with the emergence of computer systems.
The first biometric device was devised by Sir William Herschel who listed 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 maintain his job during payday. This was the first time ever that finger and hand images were captured for the purpose of identification. This step was a benchmark in terms of safety management, during the years measures were taken steadily for further advancement of these devices. Algorithms were created for Finger image and facial excellent 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 so as to recognize the lifeless body of Osama Bin Laden.
The current era has seen a boom in the emergence and use of Biometric security devices, from banks to work place and even faculty and colleges have begun to apply this advanced and a lot more reliable form of security. Seems like the prevalence and use of biometric is only going to grow a whole lot farther in the future.
