🎯 Understanding Biometrics: Types and Applications
Brief Overview:
Biometrics refers to the unique physical and behavioral characteristics of individuals that can be used for secure identification and verification. The technology has evolved significantly, finding applications in various sectors, from everyday smartphone security to forensic investigations.
Biometric systems are categorized into two main types: behavioral and physical biometrics.
Behavioral biometrics focuses on patterns in human behavior, such as gait, keystrokes, and voice, while physical biometrics examines unique physical traits like fingerprints, facial recognition, and iris patterns.
This study note will explore the various types of biometrics, their practical applications, and the technological advancements that enhance their security features.
