Unknown Facts About Biometric Authentication That Were Out of Your Sight

Besides the use of biometric authentication in a day-to-day life, people don’t have much knowledge about this technology which creates confusion and misconception. Most of the people relate biometric recognition directly to the voice, iris, fingerprint and facial identification. However, biometric technology is not limited to these popular modalities and is also not extremely superficial as people know it to be.

There are so many unknown facts about biometrics that people usually don’t know. Have a look below to know some uncommon facts associated to the biometric technology.


In early days biometric was primarily related to the forensic department or was deployed for some specific tasks and applications. However, biometrics these days are pretty common among all the working sectors for the purpose of security.

It may look like biometric has emerged recently whereas this technology is way older than you can imagine. It has a long past with true facts which will convince you that the roots of this biometric technology hold more history then you know. In the beginning of the 19th century, people witnessed a fingerprinting recognition method for law enforcement application and forensics.

Before introducing fingerprinting in the market another identification method called the Bertillon system prevailed in many countries all across the world. It was a method that was based on the science of anthropometry, which emphasizes majorly on the measurement of different parts of the human body. Alphonse Bertillon was the one who developed this system to create a proper criminal record. However, this system was soon replaced by fingerprint identification due to the misidentification and inadequacies.


Majority of people, even the non-consumers, who are not directly linked to the field of biometric technology know so little about the biometric authentication. They just consider that it is limited to recognize the user’s finger, eyes or voice. Whereas with the advancement in technology, the method of biometric authentication is much improved in the mobile devices.

Biometric authentication is not limited to a few popular modalities but there are a number biometric modalities which include some unusual ones that are still under development. Behavioral pattern, vein pattern, gait pattern, and DNA profiling, etc. are some of the biometric modalities that are used for specific applications.

Below mentioned are some uncommon biometric modalities we generally don’t hear much about:

  1. Shape of ear
  2. Gait
  3. Thermography
  4. Body odor
  5. A pattern formed by lips

There are many more biometric modalities that are left to explore. Scientist often says that all human characteristics are so unique that can give birth to new biometric methods. Whereas there are some technical restrictions and boundaries that don’t allow them to create new methods.


A common myth about the biometric facial scanner is that it scans a human face and save the image with all the records. Next time when the same person uses the device for authentication the machine matches the face with the image that is recorded in its storage. However, the story is a little twisted. When people scan their face, the device scans the face and generate codes that help the machine to recognize the same face other time. You must know that machine understand digits or codes only.


People believe what they see and that is the only reason why people think that the biometric authentication is limited to a pool of applications. Social media and movies are the reason why people think biometric technology is easy to replicate. However, there are multiple applications that you might not know about. Biometrics is used by border control agencies to identify international travelers to create an accurate record. Payment apps also use the same technology as well as the government and private organizations. From document security solution to medical sectors, biometric technology has taken over the world.

With the advancements in technology, the methods of biometric are evolved and expected to improve more with the passage of time. Also, the innovative way of biometrics is expected to maze the audience more.


Like other known biometric methods (face, fingerprint, and voice), there are certain modalities that have been discovered and processed but not executed. These type of identification technologies are available for people in the special sector and no one from other technology firms is allowed to replicate them.

For instance, EyeVerify is a known biometric solution provider, which is a USA based organization. This company developed the Eyeprint ID which is unique and allows authentication with scanning the blood vessels visible on the white side of the naked eye. Also, Fujitsu’s finger-vein recognition is known for introducing patented technologies.


Biometric recognition methods have gained good publicity in the security market where people trust future technologies more for their convenience.
