What is Biometric Technology?

Spread the love

For centuries we used a simple lock and key to keep our valuable safe, but in the last couple of years, biometric technology has become the norm. Fingerprint or thumb impression is a form of Biometric technology and identical fingerprints for two people is almost rare. This technology is widely implemented in door locks and in safes. There is now a wide variety of biometric safes available in the market.

All of us have an inkling that it has something to do with our thumbprints but none of us have an actual idea of what it truly entails.

This article you’re reading is here to clear away your confusion and hopefully answer all your queries. So basically biometrics, in very easy terms means tools that are used for recognition of a human based on their physical and behavioral aspects.

Everyday Biometric Technology

For example think your iPhone, before the iPhone 4 was released you had to enter a four digit code in order to unlock your phone but when the iPhone 5s came out, it allowed you to unlock your phone by simply placing your thumb on the home button. That feature uses biometric technology. Biometric technology has become so commonplace that at times we don’t notice when we’re using it, for instance, whenever you upload a photo on Facebook, the site immediately offers to tag your friends who are in the picture, the site does this by using biometric technology.

What is Biometric Technology? 1

Using biometric technology in everyday life is becoming exceedingly common because of two major of reasons. Firstly it’s fast which enables us to save more time and secondly, it’s far more accurate than any manual measure we use. Chances of human error have been greatly reduced as there no complicated passcodes to remember, we don’t have to carry around a bunch of keys and cards and nor do we have to hassle with security guards anymore.

What the Future Holds

Biometric technology doesn’t limit itself to using just thumbprints, it also enlists the help of other physical and behavioral characteristics like face, smell, retina, DNA, voice, the manner of walking and even voice. Scientists are continuously making developments in this field by trying to further advance its reach by including electronic tattoos, brain waves, a pill with a microchip in it that is mechanized when it comes into contact with the acid in our stomach, creating a radio signal. The possibilities regarding biometric technology are endless.

Problems with Biometrics

Biometric technology is moving ahead by leaps and bounds but there are certain risks associated with using them. There is a bit of a security concern when it comes to biometrics as DNA like keys or a password can be stolen and replicated, although the skill level needed to steal DNA is higher. We, humans, leave our fingerprints on every single object, living or inanimate, we touch and that can be a problem as our prints can be duplicated on silicone and other materials. So what you’re thinking is that we can use our voices rather than our fingerprints as a password and our problems will be over! Wrong. A voice can be recorded and used without the biometric software knowing the difference. The same thing applies to facial recognition, anyone in possession of an HD camera can capture facial features and use them. One of the biggest problems that arise is that a person cannot change their facial characteristics like they can change their password or their locks.


In the end let’s lament on all the other possibilities biometric technology affords us, now instead of keeping our valuables in safes that can easily be opened if the robber can pick locks, we can use biometric technology in order to ensure that our goods never leave our premises. Sure biometrics has its problems but compared to the options we have, they are much more safe, convenient and most importantly… quick.
