Biometric systems enhance security protocols by using unique physical characteristics, like fingerprints, facial recognition, or iris patterns, for identification and authentication. This technology offers a higher level of security compared to traditional password-based systems, as biometric traits are difficult to replicate or steal. Implementing biometric systems enables organizations to restrict access to sensitive data and facilities, reducing the risk of unauthorized entry. Moreover, the convenience of biometrics enhances user experience, as individuals can authenticate their identities quickly without remembering complex passwords, thus streamlining security processes.
