Question

An automatic teller machine (ATM) uses a form of constrained user interface to limit the user's ability to access resources in the system. Specifically for ATMs, which method is being used?

a) Biometric Authentication
b) Two-Factor Authentication
c) Token-based Authentication
d) Limited Input Keypad

Answer 1

An automatic teller machine (ATM) uses Token-based Authentication to limit the user's ability to access resources in the system. Token-based authentication ensures that only authorized users with the correct token can access the ATM's services.

Step-by-step explanation:

An automatic teller machine (ATM) uses Token-based Authentication to limit the user's ability to access resources in the system. With token-based authentication, the user is provided with a physical device, such as a card or key, which contains a unique code or token.

When the user inserts the token into the ATM, the machine verifies the token to authenticate the user's identity and allow access to the desired resources, such as cash withdrawal or balance inquiry.

This form of authentication ensures that only authorized users with the correct token can access the ATM's services, providing a level of security and preventing unauthorized access.
