This is a pure biometric which each and every person has within them; it’s a predominant behavior pattern where we could recognize other individuals by face, bodily construction or their voice somewhat unconsciously. Even thumbprints are used at different places as a kind of signature notably by those who can’t read or write, this is because every thumbprint is unique to its owner. In times that date back to as much as the Babylonian era, fingerprints were used for business transactions.
Fast forward to several years after, seeing cool gadgets was just restricted to big budget science fiction films and we were mesmerized and fascinated with them. Machines scanning retina and fingerprints or those that served on voice recognition were things that just featured in James Bond films and nobody ever thought they would get to watch and utilize such technologies in their everyday life. All of it sounded like some magic stuff of a faraway land but soon it took the form of a reality.
The first biometric device was invented by Sir William Herschel who listed a handprint on the back of a contract for every employee so as to know who were his workers and who were the outsiders claiming to maintain 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 measures were taken steadily for further progress of those devices. Algorithms were made for Finger picture and facial excellent measurement and an iris excellent measurement algorithm was also developed by the U.S authorities 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 development and application of Biometric security apparatus, from banks to work area and even faculty and schools have begun to apply this advanced and a lot more reliable form of security. Seems like the prevalence and usage of biometric is only going to grow a whole lot farther in the future.
