Systems Security Certified Practitioner – SSCP – Question0179

Which of the following biometric parameters are better suited for authentication use over a long period of time?

A.
Iris pattern
B. Voice pattern
C. Signature dynamics
D. Retina pattern

Correct Answer: A

Explanation:

The iris pattern is considered lifelong. Unique features of the iris are: freckles, rings, rifts, pits, striations, fibers, filaments, furrows, vasculature and coronas. Voice, signature and retina patterns are more likely to change over time, thus are not as suitable for authentication over a long period of time without needing re-enrollment.
