At Walt Disney World, biometric measurements are taken from the fingers of guests to ensure that the person's ticket is used by the same person from day to day.

Biometrics have 2 different functions.
-
Verification A pre-stored template is matched against a sample directly, e.g a card or known database entry.
- Identification Identifying from all the templates which one is the closest match to the input sample.
|
-How accurate is the biometric?
Testing is expenisive in terms of money, time, and resources. On the other hand, the test must be precise enough to yield a very close approximation of the inherent matching capabilities of the biometric system in question.
