You work in the IT department of a highly secure government facility, and you are evaluating different biometric methods of computer authentication. Of the following, which method of biometric authentication is considered the least reliable?

A. Fingerprint scan

B. Hand geometry scan

C. Retina scan

D. Voice analysis

Solution

Answer :-
D.Voice Analysis is the least reliable we can say because
finger print scan will be very unique and very fast to take information [most reliable]

and hand geomettry scan also unique and not much reliable then finger print.

Retina scan is very most reliable because it is very unique than fingerprint but it consumes more time to scan.
