论文摘要
受控查询评估（CQE）是保证数据库和知识库系统数据隐私的方法。 CQE系统具有审查功能，可能会使查询的答案扭曲以隐藏敏感信息。我们介绍了受控查询评估的高级形式化，并定义了CQE系统的几种理想属性。最后，我们建立了两个无关定理，这表明无法获得这些属性的某些组合。
Controlled query evaluation (CQE) is an approach to guarantee data privacy for database and knowledge base systems. CQE-systems feature a censor function that may distort the answer to a query in order to hide sensitive information. We introduce a high-level formalization of controlled query evaluation and define several desirable properties of CQE-systems. Finally we establish two no-go theorems, which show that certain combinations of these properties cannot be obtained.
