Hello friends , Biometric system used to security and private support and it’s a great electronic technology .
Biometric system it’s a automatical methods of a recognizing a public security and it’s a private support or physical or behavioral characteristic. Some examples are fingerprint, face, iris, hand geometry, voice and dynamic signature. These, are many others, are in various stages of development & deployment. The type of the biometric that is “best ” vary significantly from one application to a different .
How biometric work
Authentication by biometric verification it is become a increasingly comman in a corporate and public security system , it’s a electronic and point of sale application . In addition to the security , driving force behind the biometric verification has a convenience , as there are the no password to remember or security tokens Carry . biometric system are the methods such as measuring a person’s gait , can a operate with no direct contact with the person beening a authentication.
Biometric system performance
the biometric system of a different positioning on the acquiring sensor to environmental changes , to deformation and noise , it is impossible that the two samples of the biometric acquired in different session , exactly coincide The his reason the matching is performed by an algorithm which computes a similarities score and compare it with threshold , in case the similarly is greater than the threshold the system claim that the two samples coincide. Differently from a password matching sometimes biometric system may be incorrect the main system errors are usually measured in terms.

- Matured technology based on years of research &
- Do not change naturally
- Has wide acceptance in the security community
- The equipment is cheap
- to other biometric system
- Quick alert
- Vulnerable to noise and distortion brought on by
- dirt and twists.
- Some people may feel offended about placing their
- fingers on an equivalent place where many people
- have continuously touched
- missing or injured body part problem
- The scanning of eye is fearful to some peoples
There is a great demand for the fast , and along with the tremendously accurate authentication biometric system !
Biometric is a very interesting and exciting field .
Biometric is an area with many opportunities for growth.
Its a matured technology based on accuracy .
