In the context of de-identification, which statement best describes the main purpose of not retaining identifying information?

• A. To improve data analysis speed.
• B. To protect privacy by removing identifying information.
• C. To facilitate data sharing with other researchers.
• D. To ensure accuracy of results.

Answer: (B)

Protecting privacy by removing identifying information is the main aim of de-identification. By stripping or coding direct identifiers (like names and addresses) and removing or masking indirect identifiers that could hint at who the data belong to, the data become much harder to link back to a specific person. This reduction in re-identification risk is what lets researchers analyze data and share it under appropriate safeguards without exposing individuals. While de-identification can influence how data are shared or may affect some analyses if variables are altered, the core purpose remains privacy protection. It’s also important to remember that de-identified data aren’t guaranteed to be completely anonymous—re-identification could be possible if combined with other information, so additional controls like data-use agreements and access restrictions are often used.
