Biometric authentication

Definition

Biometric authentication is a security process that relies on unique physical characteristics of an individual, such as fingerprints, facial recognition, or iris scans, to verify their identity. This technology provides a higher level of security compared to traditional methods like passwords or PINs, as it uses traits that are inherently tied to the individual. As technology advances, law enforcement agencies increasingly incorporate biometric authentication to enhance their operational effectiveness and improve security measures.
