What does Steve's technological solution for identifying people based on walking patterns implement?

• A. It implements a two-phase authentication process using walking patterns and RFID badges.
• B. A single-factor authentication system based on passwords.
• C. A biometric fingerprint-only system.
• D. An authentication method based on IP addresses.

Answer: (A)

This question targets how two-factor authentication can be implemented by combining what someone is with what they have. Using walking patterns as a biometric identifies a person by their gait, while an RFID badge serves as a physical token the person carries. Together, they form two independent factors: a biometric factor (walking pattern) and a possession factor (RFID badge). In practice, the system would verify the gait and also require the badge to be presented, making the authentication flow a two-phase process that ensures identity only if both checks succeed. It isn’t just a password-based or fingerprint-only solution, and it isn’t based on IP addressing.
