BIOMETRICS- Secured or can be Hacked

Now a day’s, biometrics take more attention from the security point of view. Due to its huge usage in all and every sector like Banks, Nationals, and Internationals security, Tour and Travel agencies, etc. Its application is varied in all the different sectors like such as

  •  Forensic it is used for the surveillance, identification of criminals, probation and home arrest,
  • In Government, it is used for electronic voting in the local or national elections,
  • In Bank Sectors, it is used to access the account, online banking, ATMs, E-commerce, etc. and
  • In the Travelling sectors, this application is used to verify the identity of the individual at the time-traveling like Air travel, Passports, Employee access, and border crossing.

The technology, Biometrics is derived from two words, i.e. “Bio” means “living organism” and “metrics” refers to the term “application of mathematical statistics”.  It studied the Physio- behavioral features of the human body for authentication and identification, i.e.

  • Finger and Palm Print,
  • Face, Iris, and Retina Recognition,
  • Hand Geometry,
  • Gait Pattern,
  • DNA Matching,
  • Voice Recognition,
  • A Signature, and Typing Rhythm, etc.


It stored and secure the data in large quantities for a long time period, which comes helpful in the case of emergency like the accidental case, criminal investigation, etc., or we can say that it is a blueprint of the human body. This is the greatest security processor from the forensic science point of view and the other security purposes. Once start to use this technology then don’t need to remember all things like passwords and your security is always with you wherever you go. here are a few advantages 

  • High security and assurance - Biometric identification answers the question "what a person has and is" and aids in identity verification.
  • User Experience — Simple and quick
  • Non-transferable (non-transferable) – Everyone has access to a set of biometrics that is unique to them.
  • Biometrics are difficult to forge or steal.


Facial recognition can be easily fooled by using the higher resolution video or a photograph of the person, in this technology an algorithm is made by the device which cannot tell the difference between the digital image and the real face. similarly, the voice recognition can be hoaxed by using the recorded tape in the other devices. As well as in the iris recognition technology was also hacked by the hackers by using high-resolution images of 1200 dpi in which 75% of the eye is visible. These major drawbacks have to be kept in mind to use this technology. A few major disadvantage of biometric technology are 

  • Costs - A significant investment in biometrics is required for security.
  • Breach of biometric databases - Biometric databases can still be hacked.
  • Tracking and data – Biometric equipment, such as facial recognition systems, might compromise individuals' privacy.
  • Bias - To reduce biometric demographic bias, machine learning and algorithms must be quite advanced.
  • False positives and inaccuracies - False rejects and accepts can still happen, prohibiting certain users from using services.
