IPA has two key privacy-preserving features. First, it uses <em>Multi-Party Computation (MPC)<\/em> to avoid allowing any single entity &mdash; websites, browser makers, or advertisers &mdash; to learn about user behavior. Mozilla has some experience with MPC systems as we&rsquo;ve deployed <a href=\"https:\/\/blog.mozilla.org\/security\/2019\/06\/06\/next-steps-in-privacy-preserving-telemetry-with-prio\/\">Prio for privacy-preserving telemetry<\/a>. Second, it is an <em>aggregated<\/em> system, which means that it produces results that cannot be linked to individual users.
