Biometrics

Biometrics encompasses identification techniques based on a person's physical or behavioural characteristics (fingerprint, facial recognition, handwritten trace, voice). In electronic signatures, a biometric signature can capture the handwritten trace on a touchscreen (speed, pressure, angle) to create a direct link between the signatory and their consent. Under eIDAS, biometrics alone is not sufficient to reach the advanced level (AES): it must be combined with strong authentication. Biometric data is considered sensitive under the GDPR and its processing requires explicit consent.
