The problems of BIOMETRIC
Certainly a fingerprint or iris scan can identify an individual. Unfortunately, the means for acquiring biometric records are neither convenient nor inexpensive. Even then, biometrical records will not result in a completely secure system. Obtaining a copy of an individual's biometrics can be trivial. I have seen two movies where a waitress lifted a fingerprint from a glass in a restaurant for nefarious uses. There are also devices that can capture iris images of a person walking within a few feet of a video camera (often behind a one-way mirror) so that it can be duplicated and used for illegitimate purposes. The real problem with biometrics is that once an individual's biometrics has been compromised, they are compromised for life and can never be trusted again. However, my most severe objection to biometrics as an authentication method is their reliance on a central database that contains the identifying graphic templates. If such database is compromised, then the biometrics of ALL users in the database are compromised for life.
Voice recognition must be also considered as a potential authentication biometric. Unfortunately, the technology is as yet not sufficiently reliable, is expensive and difficult to implement. It also suffers from all of the disadvantages of having to rely on a central database for storing voiceprint templates.
Advantages of Biometrics :
* 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. Minimize the opportunity for ID fraud, buddy punching.
* Eliminate problems caused by lost IDs or forgotten passwords by using physiological attributes. For e.g. Prevent unauthorized use of lost, stolen or "borrowed" ID cards.
* Reduce password administration costs.
* Replace hard-to-remember passwords which may be shared or observed.
* Integrate a wide range of biometric solutions and technologies, customer applications and databases into a robust and scalable control solution for facility and network access
* 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 of a Biometric:
· * 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
much noise in the environment this method
maynot
authenticate
correctly. Therefore this method of
verification
is
not workable all the
time resulting in differences.
· * Biometrics is an expensive security solution.
