ITPEC IP October 2022 Question 38
ITPEC IP October 2022 — Question 38 of 100
Entering characters located at remembered positions in a displayed table is matrix authentication. The table's contents or arrangement can change, while the user remembers a pattern of positions, reducing the need to enter a fixed password directly.
Answer (c)
Why not others:
- a password usable once is a one-time password, not single sign-on
- one authentication granting access to multiple systems is single sign-on, not a one-time password
- fingerprints and voiceprints are biometric authentication, not challenge-response by definition
Key rule: Matrix authentication derives a response from selected coordinates in a changing grid.
