Unlike the use of other forms of authentication, such as passwords or
tokens, biometric recognition provides a strong link between an
individual and a claimed identity.
One area where biometrics can provide substantial help is in guarding
against attempts to establish fraudulent multiple identities or prevent
identity fraud. By searching through the stored references, individuals
who appear to have previously enrolled using a different identity can
be highlighted for further investigation. It is very difficult to
perform this type of check without the use of biometrics.
What constitutes a good biometric system is not a simple question
because the answer depends greatly on the requirements of the
application. Desirable factors include:
- Accurate discrimination between individuals
- Speed of operation
- The ability to deal with present and future numbers of individuals
- Environmental robustness
- Ease of use
- Capable of coping with as much individual variability as possible
- Social acceptability, i.e. people are happy to use it
- Secure and robust against potential attackers.
