Certified Information Privacy Technologist (CIPT) — Question 2

How does k-anonymity help to protect privacy in micro data sets?

Answer options

• A. By ensuring that every record in a set is part of a group of "k" records having similar identifying information.
• B. By switching values between records in order to preserve most statistics while still maintaining privacy.
• C. By adding sufficient noise to the data in order to hide the impact of any one individual.
• D. By top-coding all age data above a value of "k."

Correct answer: A

Explanation

The correct answer is A because k-anonymity ensures that each record cannot be distinguished from at least 'k' other records, thus protecting individual privacy. Options B and C involve different techniques for privacy protection but do not relate to k-anonymity. Option D is a specific method of data modification that does not align with the concept of k-anonymity.
