Privacy-Preserving Biomedical Data Sharing

点击翻译按钮获取中文摘要

The adoption of Electronic Health Record (EHR) systems has accelerated the collection and sharing of health data. EHR databases are often integrated with biorepositories and shared to facilitate genome-wide association studies (GWAS). While such integration and sharing of biomedical data have many social benefits (e.g., personalized medicine), it also raises concerns about individual privacy. A recent survey on privacy attacks demonstrates various techniques for breaching biomedical data privacy, and these techniques question the efficacy of the protection mechanisms that are currently in practice.
