数据隐私的禁忌定理

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一种方法。CQE系统的特征在于可以扭曲查询的答案以隐藏敏感信息的审查功能。我们介绍了一个高层次的形式化的控制查询评估和定义CQE系统的几个理想的属性。最后，我们建立了两个不去定理，这表明这些属性的某些组合不能得到。

英文摘要：

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.
