What is Biometric Authentication?

Biometric authentication is a security process that verifies a user's identity based on their unique physical or behavioral characteristics. Instead of relying on traditional methods like passwords or PINs, biometrics leverages distinctive traits such as fingerprints, facial features, or voice patterns to confirm a person's identity.

Enhanced Security
Biometric data is highly unique to each individual, making it significantly harder to compromise compared to passwords which can be easily forgotten, stolen, or guessed.
Convenient User Experience
Biometric authentication offers a seamless and user-friendly experience, eliminating the need for users to remember complex passwords or carry physical tokens.
Stronger Fraud Prevention
Biometric authentication adds an extra layer of protection against unauthorized access, reducing the risk of fraudulent activities.
Streamlined Access
Biometric systems can quickly and accurately verify a user's identity, providing efficient access to services and applications.

Biometric Authentication Methods

Biometric authentication leverages various unique physical or behavioral characteristics for user verification. Let's focus on two of the most common and convenient methods: fingerprint authentication and facial recognition.

Facial Authentication

Facial authentication technology analyzes distinctive facial features to verify a person's identity.
High accuracy
Fingerprints offer a high level of precision in identifying individuals.
Wide availability
Fingerprint sensors are integrated into many modern devices, making them easily accessible.
Quick authentication
Fingerprint scans can be processed rapidly, providing seamless user experiences.

Facial Authentication

Facial authentication technology analyzes distinctive facial features to verify a person's identity.
User-friendly
Facial recognition is often perceived as more convenient than other biometric methods.
Passive authentication
In some cases, facial recognition can be performed discreetly without requiring user interaction.
Potential for liveness detection
Advanced systems can detect spoofing attempts by ensuring a live person is present.

Biometric Authentication Flow

How does biometric authentication work? Below are the key steps in biometric authentication flow:

Key Generation

Upon registering biometric login, a pair of cryptographic keys is created by Secure Enclave, so the private key is protected by hardware and never left the device.
  • The private key is securely stored on the user's device (Secure Enclave for iOS, Hardware-backed Keystore for Android).
  • The public key is stored on the Authgear server.

Authentication

  • The user presents their biometric (fingerprint or face) to unlock the device's private key.
  • The server sends a challenge to the devices.
  • The device uses the private key to sign the challenge.
  • The signed challenge is sent to the Authgear server as a response.

Server Verification

  • The Authgear server verifies the digital signature using the stored public key.
  • If the signature is valid, the user is authenticated.
