Privacy Enhancing Technologies

How does k-anonymity help safeguard privacy in microdata sets?

  • 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."
Explanation

K-anonymity limits linkage through quasi-identifiers by ensuring that each equivalence class of matching identifying attributes contains at least k records. Thus, a record cannot be singled out from fewer than k individuals with the same quasi-identifier values.
