Biometric security refers to the use of unique physical characteristics, such as fingerprints, facial recognition, or iris scans, to authenticate individuals. This technology leverages biological traits that are difficult to replicate, making it a secure method for identity verification. Common applications include unlocking smartphones, accessing secure facilities, and enhancing online security measures. Biometric systems can be more convenient than traditional passwords, as they often provide a seamless user experience. However, concerns about privacy and data security must be addressed to ensure user trust and compliance with regulations.
