Certified Information Privacy Technologist (CIPT) — Question 51

What is a main benefit of data aggregation?

Answer options

• A. It is a good way to perform analysis without needing a statistician.
• B. It applies two or more layers of protection to a single data record.
• C. It allows one to draw valid conclusions from small data samples.
• D. It is a good way to achieve de-identification and unlinkabilty.

Correct answer: D

Explanation

The correct answer is D because data aggregation helps in removing personal identifiers, ensuring that individual data points cannot be traced back to a specific person, thus achieving de-identification. Options A, B, and C do not accurately capture the primary benefit of data aggregation; they pertain to analysis, security, and small sample validity, which are not the main focus.
