Identity Proofing relies on a person providing additional proof of who they are.

• A. Identity Proofing
• B. Privacy
• C. Confidentiality (Cryptography)
• D. Hash Function

Answer: (A)

Identity proofing is the process of verifying a person’s real identity by requiring additional evidence beyond just their claim. This can include government-issued IDs, biometric verification, or other documents and corroborating information. The goal is to establish that the person is who they say they are before granting access or services, especially during onboarding or high-risk transactions.

Why this is the best choice: it directly describes the activity of providing and validating extra proof to confirm identity, which is exactly what identity proofing entails.

Context to help understanding: identity proofing often sits at the initial enrollment stage, sometimes followed by authentication at login. It’s distinct from authentication, which is verifying that someone is indeed the claimed user during access.

Brief notes on the other options: privacy concerns protecting personal data; confidentiality (cryptography) involves keeping data secure from unauthorized access; a hash function is a cryptographic tool used for data integrity or password storage, not in itself the process of proving who someone is.
