METHODS: Privacy preserving record linkage (PPRL) utilising Bloom filters provides a unique practical mechanism that allows linkage to occur without the release of personally identifiable information (PII), while still ensuring high accuracy.
RESULTS: The methodology has received wide uptake within Australia, with four state linkage units with privacy preserving capability. It has enabled access to general practice and private pathology data amongst other, both much sought after datasets previous inaccessible for linkage.
CONCLUSIONS: The Australian experience suggests privacy preserving linkage is a practical solution for improving data access for policy, planning and population health research. It is hoped interest in this methodology internationally continues to grow.
方法:使用Bloom过滤器的隐私保护记录链接(PPRL)提供了一种独特的实用机制,允许在不发布个人身份信息(PII)的情况下进行链接。同时仍然确保高精度。
结果:该方法已在澳大利亚得到广泛采用,具有四个具有隐私保护功能的状态链接单元。它允许访问一般实践和私人病理数据等,两者都非常渴望以前无法访问的数据集进行链接。
结论:澳大利亚的经验表明,隐私保护链接是改善政策数据访问的实用解决方案,规划和人口健康研究。希望国际上对这种方法的兴趣继续增长。
