ITPEC IP October 2024 Question 35
ITPEC IP October 2024 — Question 35 of 100
Measuring the movement, pressure, and other characteristics of a handwritten signature is biometric authentication. Behavioral biometrics identify a person by a characteristic of how the person performs an action. Dynamic signature verification can compare stroke order, speed, pressure, timing, and pen movement rather than merely comparing the visible final image.
Answer (c)
Why not others:
- (a) describes CAPTCHA, which distinguishes a human user from automated software
- (b) uses a password, a knowledge factor, even though the on-screen keyboard may reduce some keylogging risks
- (d) a secret question is also a knowledge factor
Key rule: Biometrics use something a person is or does; passwords and secret answers use something the person knows.
