What is biometric authentication?

Biometric authentication nebo biometrické ověřování je způsob ověřování identity uživatele pomocí jeho jedinečných fyzických nebo behaviorálních vlastností. Mezi nejčastější metody patří rozpoznávání otisků prstů, obličeje, oční duhovky nebo hlasu. Výhodou je, že uživatel si biometrické údaje nemusí pamatovat – na rozdíl od hesel – a nelze je snadno zkopírovat.

Where can biometric authentication appear in practice

• Mobile phones – unlocking devices with a fingerprint or face scan
• Time-tracking systems – replacing ID cards with biometric sign-ins for employees
• Banking apps – confirming transactions via facial or voice recognition
• Secure facilities – controlling access to data centers or research labs
• Airport security – verifying passenger identity through biometric scanning

These examples show that biometrics are used wherever fast, convenient, and secure identity verification is needed.

How biometric authentication and other methods?

• Biometrics (something you are) – fingerprint, face, voice
• Password or PIN (something you know) – information you remember
• Card or device (something you have) – a physical item like a smartcard or smartphone

From a security perspective, biometrics are harder to misuse remotely, but unlike passwords, they can’t be changed if stolen. That’s why biometrics are best used as part of multi-factor authentication—not a standalone solution.

How to implement biometric authentication in your company

Recommended steps:

1. Assess which systems require stronger access controls.
2. Choose the right biometric method (e.g., fingerprint, face, voice).
3. Ensure compliance with GDPR and data protection laws when processing biometric data.
4. Deploy biometric systems where they are appropriate—e.g., employee access control or sensitive data access.
5. Test these systems regularly for both functionality and security.
6. Combine biometric authentication with other factors for enhanced protection.

Many companies adopt biometrics for convenience but overlook the need to protect the biometric data itself. A breach of such data can have serious consequences—after all, you can’t just “reset” your fingerprint. Biometric authentication is a powerful tool when implemented securely and thoughtfully.
