How is biometric technology used in human-computer interaction?

Biometric technology in human-computer interaction involves using unique physiological and behavioral characteristics of individuals to identify or authenticate their identity. This technology enhances security and personalization in digital systems.

Physiological biometrics includes:

• Fingerprint Recognition: Scanning fingerprints to verify identity, commonly used in smartphones.
• Facial Recognition: Analyzing facial features to confirm identity, used in security systems and smartphones.
• Iris Recognition: Examining the iris patterns of the eye for high-security authentication.

Behavioral biometrics includes:

• Keystroke Dynamics: Measuring the rhythm and pressure of typing to identify users.
• Voice Recognition: Identifying individuals based on the unique characteristics of their voice.

Example: In a smartphone, facial recognition can unlock the device by recognizing the user's face when they look at the screen. This not only provides convenience but also enhances security by ensuring that only the authorized user can access the device.

For cloud-based solutions, services like Tencent Cloud offer biometric authentication APIs that can be integrated into applications to provide secure and seamless user experiences. These services leverage advanced algorithms to ensure accurate and reliable biometric data processing.
