Biometrics is the technology, which uses various individualistic attributes of a person to verify his or her identity. Various attributes include fingerprints, geometrical shapes of hands, retina, and iris in the eyes and so on. Biometric test offers a full-proof and highly secure method of verification to avoid security breech and unauthorized access to critical data and places.
Various Characteristics Involved
The characteristics used by biometrics technology are divided into two groups - physiological and behavioural.
- Physiological characteristics involve face recognition, handprints and fingerprints, veins in hands, capillary vessels in eyes and so on.
- Behavioralcharacteristics involve voice modulations, handwriting and signature style, and keystroke dynamics.

Salient Features of Biometrics
- Biometrics makes use of those characteristics, which are universal, that is, found in each and every human being. For instance, fingerprints, voice, face print and so on.
- Distinct body odours, handwriting skills and other attributes are being included in biometrics analysis, as these characteristics don’t change with growing age of individuals.
- The characteristics involved in biometrics analysis can’t be stolen or copied. So, you can’t expect anyone to steal your face or eye vessels to use them for illegitimate access.
- Interestingly, even if someone is able to replicate your fingerprints and use it for biometrics analysis, these systems can instantly differentiate between a human body and a plastic cast, on the basis of body heat, temperature, blood flow and so on.
How Does It Work
Biometric devices, like fingerprint scanners and others, store templates of various characteristics of different people. A person is authenticated by matching his or her characteristics with those stored in the template database. Amazingly, these devices based upon biometrics technology are made capable enough to carry out the process of verification in 1-2 seconds, even if the database has thousands of templates stored in it.
Biometrics over Other Tools
Biometrics technology certainly offers alluring advantages over other security tools. While keys and passwords can be replicated or stolen, there is no such possibility in biometrics analysis. Furthermore, the credit cards, ATM cards and other such provisions can’t be misused, when accompanied with biometric test. Sharing of biometrics characteristics is not possible and thus, your trust in a friend or other close person is not victimized.
Hackers, militants and criminals can be failed in their intentions by employing biometric test at airports, building entrances, banks and other such places. Thus, the technology is growing with leaps and bounds to touch every sphere of life around us.

The biometric system is very good idea for the maintaining attendance and time management.
