Biometrics refers to technologies that recognize or analyze people using distinctive physical or behavioral characteristics. These can include fingerprints, facial features, iris patterns, voice, palm patterns, and behavioral signals such as typing or movement. A biometric system typically captures a sample, extracts measurable features, and compares them with stored or enrolled data to make a recognition decision.
Biometrics is used in smartphones, border control, financial services, healthcare systems, and workplace access. Modern solutions increasingly combine computer vision, machine learning, liveness detection, and secure biometric matching to improve reliability while reducing the risk of impersonation.
