Biometric Verification
Biometric verification is an identification method that uses a person's unique physical or behavioural characteristics to confirm their identity. It includes facial recognition, fingerprint, iris, or voice recognition.
Biometric verification is based on the principle that certain physical or behavioural characteristics are unique to each individual and difficult to forge. Unlike traditional methods based on knowledge (password) or possession (identity card), biometrics verifies what a person 'is', thereby offering a higher level of security.
In the field of KYC compliance and remote identity verification, facial biometrics is the most widespread modality. It enables the customer's face to be compared with their identity document photo without requiring any specific equipment beyond a smartphone. Other modalities such as fingerprint or iris recognition are used in high-security contexts.
The processing of biometric data is strictly regulated by the GDPR, which classifies it as sensitive data (Article 9). Its collection requires explicit consent or a specific legal basis, and enhanced security measures must be implemented for its storage and processing.

Real-world examples
- 1.A banking app allows customers to authenticate via facial recognition to access their accounts, replacing the traditional password with a quick selfie.
- 2.An airport uses biometric verification through iris recognition at automated border gates, enabling fast and secure passage for frequent travellers.
- 3.An electronic signature platform verifies the signatory's identity via smartphone fingerprint before allowing the signing of a mortgage contract.
