Definition
Biometrics refers to identification techniques based on a person's unique physical or behavioural characteristics — fingerprint, facial features, iris, voice, or the dynamics of a handwritten signature. In electronic signature systems, biometric capture is used either as a standalone signature method or as a strong-authentication factor combined with other credentials.
Indian legal context
In India, Aadhaar eSign uses biometric authentication (fingerprint or iris) against the UIDAI Aadhaar database to verify a signer's identity. Under eIDAS in the EU, biometrics alone is not sufficient to reach the Advanced (AES) level — it must be combined with strong authentication.
