Biometrics and Security

Paper Summary:

This paper considers the use of biometrics in home security, noting that biometrics involves the use of computers and other hardware to identify people on the basis of physical characteristics, such as fingerprints, speech, facial recognition, retina scan, signature, and so on. The paper further discusses how biometric security systems can operate in different ways. In an identification mode, the system can identify a person from the entire enrolled population by means of a database search. In verification mode, the system can authenticate an individual? claimed identity.

From the Paper:

"Biometrics involves the use of computers and other hardware to identify people on the basis of physical characteristics, such as fingerprints, speech, facial recognition, retina scan, signature, and so on. Biometric security systems can operate in different ways. In an identification mode, the system can identify a person from the entire enrolled population by means of a database search. In verification mode, the system can authenticate an individual's claimed identity. The advantages of such a system derive from the ability to offer a unique identification for each person: Only biometric authentication bases an identification on an intrinsic part of a human being. Tokens, such as smart cards, magnetic stripe cards, physical keys, and so forth, can be lost, stolen, duplicated, or left at home. Passwords can be forgotten, shared, or observed ("Biometrics and Security" para. 5)."
