ITPEC IP October 2019 Question 43
ITPEC IP October 2019 — Question 43 of 100
Matching a user's vein pattern against a preregistered pattern is biometric authentication. The system verifies a physical characteristic belonging to the person, making it an example of the “something you are” authentication factor.
Answer (a)
Why not others:
- a memorized screen pattern is knowledge-based authentication
- selecting requested scenery images is a CAPTCHA used to distinguish humans from automated programs
- choosing personally related images is image-based knowledge authentication rather than measurement of a physical trait
Key rule: Biometrics authenticates measurable human characteristics such as fingerprints, veins, irises, faces, or voices.
