Definition
Biometrics refers to the measurement and statistical analysis of people's unique physical and behavioral characteristics for identification and authentication purposes. Common biometric identifiers include fingerprints (Touch ID), facial geometry (Face ID), iris patterns, voice recognition, and gait analysis. In the creator and tech context, biometrics are used for device security, payment authorization, and increasingly for content moderation and age verification. The use of biometric data raises significant privacy concerns and is regulated in many jurisdictions.
