Review on Privacy Protection of Electronic Medical Data in Cross-domain Sharing

Abstract

With the rapid development of information technology, the medical industry is rapidly moving in the direction of smart medical care, and more and more users tend to put their medical data in cloud servers, so as to share them safely among Internet hospitals. Electronic medical data stores all patients' medical information, and its high value is obvious to all, which also leads to the attack of illegal elements, which leads to the leakage of patients' private data. In addition, the cloud server used to store data is semi-trusted, so it is necessary for the intelligent development of the medical industry to ensure that the private data is not leaked when the electronic medical data is shared among internet hospitals. This paper deeply discusses different technical schemes to protect medical data, and then realizes the privacy protection of electronic medical data.
