A framework for privacy-preserving healthcare data sharing

As healthcare data is quite valuable to many organizations for scientific research or analysis, the demand of sharing healthcare data have been growing rapidly. Nevertheless, health care data usually contains a lot of patient privacy. Sharing that data directly would bring huge threaten to patient privacy. It´s necessary to develop practical methods to balance health care data sharing and privacy protection. Although many approaches have been developed to deal with these problems, most of them are focusing on a small scope of the problem with single theory. In this paper, we´d like to introduce a framework for privacy preserving data sharing with the view of practical application in more comprehensive way. The framework focuses on three key problems of privacy protection during data sharing which are privacy definition and detection, privacy protection policy management, privacy preserving health care data sharing. And solutions to these three problems are discussed in details. A simple implementation of the framework would be introduced to solve the problems of privacy-preserving electronic medical records publishing.
