Answer:
Biometrics in this sense refers to any human information that can be used as unique identifiers such as fingerprints, iris scan, facial scan, voice patterns and typing cadence.
The advantage of biometrics is that they can not be duplicated. That is, two people can never share the same biometric information except if they are clones of each other.
Given that this kind of unique identifiers can be also be stored as data, it thus creates a cyber risk. If stolen, it may be used to access any part of the user's life. The loss of biometric data to hackers is so detrimental that it can be used to falsify legal documents, identifications documents, or other forms of and even credit card details.
