What are biometric issues?

Biometric systems can make two basic errors. A “false positive” occurs when the system incorrectly matches an input to a non-matching template, while in a “false negative”, the system fails to detect a match between an input and a matching template.

What is a primary problem with biometrics?

What is a primary problem with biometrics? Some biometric features can change over time, or with medical conditions making them less reliable and forcing a re-identification phase to resync a user and their biometric.

What problems do biometrics solve?

Biometric identification systems record immutable personal characteristics in a machine-readable format. When used by governments, they can solve a hard problem: verifying personal identity in a way that cannot be faked.
