ITPEC IP April 2023 Question 43
ITPEC IP April 2023 — Question 43 of 100
Iris, fingerprint, and vein recognition are all biometric authentication methods, while a PIN is not. Biometrics use measurable physical or behavioral characteristics of a person. Iris patterns, fingerprint ridges, and vein patterns are inherent biological traits and are compared with enrolled templates.
Answer (c)
Why not others:
- I PIN is a knowledge factor: something the user knows
- II Iris, III Fingerprint, and IV Vein are biometric factors: something the user is
- (a) incorrectly includes the PIN; (b) omits vein recognition; (d) omits iris and fingerprint
Key rule: Passwords and PINs are knowledge factors, tokens are possession factors, and bodily or behavioral traits are biometric factors.
