Authentication
Biometric Authentication
Biometric Authentication uses unique physical or behavioral characteristics (fingerprints, facial recognition, iris scans, or voice patterns) to verify a user's identity. It is a possession factor that is harder to compromise than knowledge factors because biometric data cannot be forgotten or easily guessed.
What Teams Run Into
Biometric data is permanent: it cannot be rotated like a password. If biometric data is stolen and used to train an AI model, spoofing becomes possible forever.
Biometric accuracy varies by environment. Fingerprint scanners fail when hands are wet or worn. Facial recognition fails in poor lighting or masks. False rejection rates increase in real-world conditions.
Biometric collection raises privacy concerns. Organizations must store biometric templates securely, meet consent requirements, and handle regulatory scrutiny around biometric data.
Why It Matters
Biometrics are the most human of authentication factors: you cannot delegate them, forget them, or share them easily. But biometric data is not a secret: everyone leaves fingerprints and faces wherever they go. Biometric authentication is strong only if the biometric template is protected as aggressively as a cryptographic key. Once biometric data is exposed, the user is compromised permanently.
