Name an example of biometric data.

Biometric data refers specifically to personal data derived from an individual's physical or behavioral characteristics that can be used to identify them. Fingerprints and facial recognition data exemplify this as they are unique to each individual and cannot be easily replicated or forgotten.

Biometric data is distinct from other forms of data such as usernames and passwords, which rely on user-generated information and can be changed or lost. Similarly, a social security number is a unique identifier but it is based on a number assigned rather than a physical characteristic. An IP address, while unique to a device on the network, does not serve to identify an individual in the same personal and immutable way that biometric traits do. Therefore, fingerprints or facial recognition data is the most accurate category under which biometric data falls.
