A Blockchain-based Approach to the Secure Sharing of Healthcare Data

Electronic health record (EHR) sharing enables to improve the quality and reduce the cost of healthcare, but it is still challenging because of technique issues even though patients and healthcare organizations are willing to share. These technical barriers include confidentiality, privacy, interoperability, integrity and so on. In this paper, we propose a blockchain and MedRec-based approach by implementing signcryption and attributebased authentication to enable the secure sharing of healthcare data. By implementing this approach: 1) all patient’s fragmented EHR pieces can be viewed as a whole record and stored secure against tampering; 2) the authenticity of patients’ EHRs can be verified; 3) flexible and fine-grained access control can be provided and 4) maintaining a clear audit trail is possible.
