Reveal correct answer
Correct answer: D
Explanation
A voiceprint, which is a digital representation of the sound, rhythm, physical characteristics, and patterns in a person's voice, is an example of biometric authentication. Biometric authentication is a security process that relies on a person's unique biological characteristics to verify his or her identity (see the ISC2 Study Guide, Domain 3).
For example, a company might use voiceprint authentication for its telephone banking services. When a customer calls, the system would compare the customer's voice to the voiceprint on file. If the two match, the system would authenticate the customer and allow access to banking services.
The other options are not examples of biometric authentication. An email address and password, a combination of OTP and PIN, or a combination of physical key and password are examples of something you know (password, PIN) or something you have (email address, physical key), not something you are (biometric).
