Certified Information Privacy Technologist (CIPT) — Question 171

What privacy risk is NOT mitigated by the use of encrypted computation to target and serve online ads?

Answer options

• A. The ad being served to the user may not be relevant.
• B. The user's sensitive personal information is used to display targeted ads.
• C. The personal information used to target ads can be discerned by the server.
• D. The user's information can be leaked to an advertiser through weak de-identification techniques.

Correct answer: D

Explanation

The correct answer is D because weak de-identification techniques can still lead to user information being exposed, even when encrypted computation is used. Options A, B, and C are all related to the relevance and usage of ads but do not directly address privacy risks associated with data leaks.
