Biometrics are any metrics that can be used to identify a human being. The most common biometric recognition system is Apple’s Face ID and fingerprint recognition to unlock the iPhone. Biometric data storage can be hacked into allowing cybercriminals to access the biometric data. There is room for false positives meaning a criminal may be able to duplicate some parts of your physical identity like obtaining your fingerprints from a cup. There are some privacy concerns with biometrics because hackers can track you all that is needed.
