The technology that uses biometry for authentication processes includes systems that analyze unique physical or behavioral characteristics of individuals, such as fingerprints, facial recognition, and iris scans. These biometric methods provide a high level of security by tying access to unique attributes that are difficult to replicate or forge. Such systems enhance user verification in various applications, ranging from secure mobile devices to access control in sensitive environments. As biometric technology advances, it offers convenience and security in verifying identity without traditional passwords.
