Three modes of
verification (called factors of authentication) are what-you-know,
what-you-have and who-you-are. Canonical respective are password, key
and bio-metric. A key can be private-public with private not
extricable. Here, one may set (private-public) map such that knowing
even half of maps has negligible effect on decoding the map. Then
strong two factor security is possible without password. Its like a
bank locker, you must be authorized to operate and have the key. No
password is needed.
Indeed one may require
biometric identity to even enable the key. It is like a lock opened
only when many bankers insert the keys at once. Or two people enable
launch of nuclear weapons. Collusion can be defeated so. Never in
history of banking or nuclear weapons have securities been breached,
always very close at best.
India has aadhaar. All
phones starting 10 K cost ban have fingerprint readers. Iris-print
readers have started and can be easily added to any mobile. Using
aadhaar as base, very rich set of unhackable defenses can be built
simply using what-you-have and who-you-are. The last is used to
enter mobile bio-metrically. This 2 factor destroys all hacking,
including extreme social engineering or theft/loss etc.
USA target is 2021. India
can realistic by end 2017. Cash economy can be demolished. All the
opposing emfubar, pretending to oppose only the evil effects can be
permanently retired from public life. In most states in USA, felons
are not allowed to vote or run. By law, opponents can be nailed! Even
here, jailed can not vote but still run! Time to fix to permanently
retire Sir Lalu!
