Which of the following is a type of physical security?

Option D

The dictionary definition of biometrics is, “The measurement and analysis of unique physical or behavioral characteristics especially as a means of verifying personal identity.” Unique physical features can mean anything from fingerprints and facial features to speech and keystroke patterns.

Biometrics have been around for a long time. There’s evidence cave dwellers used handprints as a form of “signing” their paintings on cave walls and as early as the late 14th century Chinese parents were using palm and foot prints to distinguish young children from each other. In the late 1800’s, law enforcement and courts began to see fingerprints as a useful forensic tool for solving crimes.

It wasn’t until the development of computers with large, easily searchable databases that biometrics begin to take off. Advanced computer technology allowed the collection of large amounts of biometric information that could be easily accessed and analyzed.
