Biometrics

Biometrics encompasses identification techniques based on a person''s physical or behavioral characteristics (fingerprint, facial recognition, handwriting pattern, voice). In electronic signature, biometric signature can capture the handwriting pattern on a touch screen (speed, pressure, angle) to create a direct link between the signatory and their consent. Under eIDAS, biometrics alone is insufficient to reach the advanced level (AES): it must be combined with strong authentication. Biometric data is considered sensitive under GDPR and its processing requires explicit consent.
