6.Moreover, today's fast-paced
electronic world means people have to remember a
number of passwords and Personal Identification Number
(PINs) for computer accounts, banks, ATMs, E-Mail,
wireless, phones ,websites and so forth.CONCLUSION
Biometric authentication is highly reliable, because
physical human characteristics are much more difficult to
forge than security codes, passwords and hardware keys.Sound principles of system engineering are still required
to ensure a high level of security rather than purely
depend on invariant biometrics features.Biometrics holds
the promise of fast, easy, accurate, reliable and less
expensive authentication for a variety of application and
users have nothing to remember.Non-repudiation
and irrevocability are concerns over Biometrics systems
based on distributed database.
