Biometrics refers to the measurement and statistical analysis of people's unique physical and behavioral characteristics. These characteristics are used for identification and access control. Biometric systems can recognize individuals based on what they are, such as fingerprints, facial features, iris patterns, or voice, or on what they do, such as typing rhythm or gait. Unlike traditional security measures like passwords or ID cards, biometrics are inherently linked to the individual, making them more difficult to steal, forge, or forget.

The primary applications of biometrics are in security and convenience. In security, biometrics are employed for border control, law enforcement, secure facility access, and protecting sensitive data. For convenience, they are used to unlock smartphones, authorize financial transactions, and personalize user experiences. The accuracy and reliability of biometric systems depend on various factors, including the quality of the sensor, the algorithm used for comparison, and environmental conditions. False acceptance rate (FAR) and false rejection rate (FRR) are key metrics used to evaluate the performance of biometric systems. Privacy concerns are a significant aspect of biometric technology, as the collection and storage of sensitive personal data raise questions about potential misuse and data breaches. Ethical considerations and regulatory frameworks are being developed to address these challenges and ensure responsible deployment of biometric systems.
