Here are some common examples of biometric security: Voice Recognition. Fingerprint Scanning. Facial Recognition.
There are three popular forms of nonbiometric security measures: callback modems, firewalls, and intrusion detection systems.
Physical security involves the use of multiple layers of interdependent systems that can include CCTV surveillance, security guards, protective barriers, locks, access control, perimeter intrusion detection, deterrent systems, fire protection, and other systems designed to protect persons and property.
Non-biometric authentication is often seen as a back-up or is used alongside biometric passwordless security, but it in fact it can be just as secure as biometric systems. A key acts as a physical unlocking device, but often without the need to be plugged into a computer.
