A Design of Blockchain-Based Architecture for the Security of Electronic Health Record (EHR) Systems

摘要

This paper presents a blockchain-based architecture for electronic health record (EHR) systems. The architecture is built on top of existing databases maintained by health providers, implements a blockchain solution to improve interoperability of the current EHR systems, prevent tampering and malicious misuse of EHRs by means of tracking all events that happened to the data in the databases. This proposed architecture also introduces a new incentive mechanism for the creation of new blocks in the blockchain. The architecture is independent of any specific blockchain platforms and open to further extensions, hence potentially fits in with other electronic record systems that require protection against tampering and misuse.
