Historically, strong data anonymization requires substantial domain expertise and custom design for the given data set and use case. Diffix is an anonymization framework designed to make strong data anonymization available to non-experts. This paper describes Diffix Elm, a version of Diffix that is very easy to use at the expense of query features. We describe Diffix Elm, and show that it provides strong anonymity based on the General Data Protection Regulation (GDPR) criteria. This document is the second version of Diffix Elm. It adds ceiling, round, and bucket_width functions (in addition to floor).
