医疗机构在与他人共享敏感医疗数据时必须遵守各种联邦和州政策。传统上，这种共享是通过净化来自各个记录的标识信息来执行的。然而，这样的清理消除了以后将属于同一患者的记录跨多个机构链接的能力，这对于医学队列发现是必不可少的。目前，人类诚实的经纪人承担非净化数据的管理，并手动促进这种队列发现。然而，这是缓慢的，容易出错，更不用说诚实的经纪人的任何妥协都会破坏系统。在这项工作中，我们描述了PriReMat，我们已经开发的隐私保护记录链接的工具集。底层协议基于我们前面介绍的强安全原语。这项工作描述了在不可信的机器和网络上的分布式实现。
Medical institutions must comply with various federal and state policies when they share sensitive medical data with others. Traditionally, such sharing is performed by sanitizing the identifying information from individual records. However, such sanitization removes the ability to later link the records belonging to the same patient across multiple institutions which is essential for medical cohort discovery. Currently, human honest brokers assume stewardship of non sanitized data and manually facilitate such cohort discovery. However, this is slow and prone to error, not to mention that any compromise of the honest broker breaks the system. In this work, we describe PriReMat, a toolset that we have developed for privacy preserving record linkage. The underlying protocol is based on strong security primitives that we had presented earlier. This work describes the distributed implementation over untrusted machines and networks.
