Description: Reliable authorization and authentication are becoming necessary for many
everyday applications such as boarding an aircraft, performing financial transaction,
logging to a secure system etc. Identity verification becomes a challenging task when
it has to be automated with high accuracy and with low probability of break-ins and
low rates of false match. Moreover, person verification is not a new problem and
society had created three traditional modes of designation:
1. Possessions: Physical possessions such as keys, passports and smart cards.
2. Knowledge: Pieces of information those are secret and known only to the right
person such as PIN, passwords, user names etc.
3. Biometrics: Physiological and behavioral characteristics of individuals that
distinguish one person from the others. These characteristics are different in
each person.
