Biometric signature

Biometric signature is a form of electronic signature that captures, in addition to the image of the handwriting pattern, dynamic behavioral data: stylus pressure, speed, angle of inclination, acceleration. These parameters create a unique fingerprint that is difficult to forge. It provides more robust authentication than a simple signature image. Biometric data is considered sensitive under GDPR and requires explicit consent. Biometrics alone is insufficient to reach AES eIDAS level; it must be combined with strong authentication.
