论文摘要
从历史上看，强大的数据匿名需要给定数据集和用例的实质性域专业知识和自定义设计。 Diffix是一个匿名框架，旨在使非专家可用的强数据匿名。本文介绍了Diffix Elm，这是一种非常易于使用的Diffix版本，以查询功能为代价。我们描述了Diffix Elm，并表明它基于一般数据保护调节（GDPR）标准提供了强大的匿名性。 该文档是Diffix Elm的第三版。第二版添加了天花板，圆形和铲斗\ _ Width功能（除了地板之外）。该文档添加了保护多种不同类型的受保护实体的能力（在早期版本的Diffix中找不到的功能）。它还增加了对任何列的计数不同值（而不仅仅是辅助列）。
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 third version of Diffix Elm. The second version added ceiling, round, and bucket\_width functions (in addition to floor). This document adds the ability to protect multiple different kinds of protected entities (a feature not found in earlier versions of Diffix). It also adds counting distinct values for any column (rather than only the AID column).
