Certified Information Privacy Technologist (CIPT) — Question 5

When releasing aggregates, what must be performed to magnitude data to ensure privacy?

Answer options

• A. Value swapping.
• B. Noise addition.
• C. Basic rounding.
• D. Top coding.

Correct answer: B

Noise addition is the correct answer because it helps to obscure the actual data values while still allowing for meaningful analysis, thus ensuring privacy. Value swapping, basic rounding, and top coding may not provide adequate protection against the identification of individuals within the data.
