How secure is a biometric system?

The higher this ATV metric the more users are able to be processed, the less number of exceptions, making criminals easier to identify.
Both AVT and FAR are excellent measures of a biometric system’s level of security.
To compare the different biometric techniques I will use the Zephyr chart analysis.
