Certified Information Privacy Technologist (CIPT) — Question 280

Revocation and reissuing of compromised credentials is impossible for which of the following authentication techniques?

Answer options

• A. Biometric data.
• B. Picture passwords.
• C. Personal identification number.
• D. Radio frequency identification.

Correct answer: A

Explanation

Biometric data, such as fingerprints or retinal scans, cannot be changed or reset once compromised, making revocation and reissuance impossible. In contrast, picture passwords, personal identification numbers (PINs), and radio frequency identification (RFID) can be modified or replaced easily if they are compromised.
