1. Biometric Authentication Methods, Advantages, and Disadvantages

2. What is Biometric Authentication? Biometric authentication is a security process that uses unique biological characteristics—such as fingerprints, facial recognition, or retina scans—to verify an individual’s identity. Unlike traditional methods like passwords or PINs, biometrics offer higher security because they are inherently linked to the individual and more challenging to replicate or steal.

3. Verification Storage Enrollment 1 2 3 The user’s biometric data (e.g., fingerprint, facial features) is captured and stored in a secure database. The captured biometric data is converted into a digital template and securely stored for future comparison. When authentication is needed, the user’s biometric data is captured again and compared to the stored template to confirm identity. How Does Biometric Authentication Work?

4. Fingerprint Biometric Authentication Methods Analyzes unique patterns on fingertips. Facial Recognition Recognizes distinctive facial features. Iris Recognition Identifies unique patterns in the iris of the eye. Voice Recognition Analyzes vocal patterns and speech characteristics. Behavioral Biometrics Examines typing patterns, gait, or signature.
