Biometrics (or biometric authentication) consists of methods for uniquely recognizing humans based upon one or more intrinsic physical or behavioral traits. In computer science, in particular, biometrics is used as a form of identity access management and access control. It is also used to identify individuals in groups that are under surveillance.

ADVANTAGES

• Increase security - Provide a convenient and low-cost additional tier of security.

•  Reduce fraud by employing hard-to-forge technologies and materials. For e.g.Minimise the opportunity for ID fraud, buddy     punching. 

•  Eliminate problems caused by lost IDs or forgotten passwords by using physiological attributes. 

• Reduce password administration costs. 

•  Replace hard-to-remember passwords which may be shared or observed. 

•  Make it possible, automatically, to know WHO did WHAT, WHERE and WHEN! 

• Offer significant cost savings or increasing ROI in areas such as Loss Prevention or Time & Attendance. 

• Unequivocally link an individual to a transaction or event.

DISADVANTAGES

• The finger print of those people working in Chemical industries are often affected. Therefore these companies should not use the finger print mode of authentication.

• It is found that with age, the voice of a person differs. Also when the person has flu or throat infection the voice changes or if there there are too much noise in the environment this method maynot authenticate correctly. Therefore this method of verification is not workable all the time

• For people affected with diabetes, the eyes get affected resulting in differences.

• Biometrics is an expensive security solution.
