A Novel Blockchain-Based Approach for Secure and Efficient Electronic Medical Record Sharing
Hussein El Ghor, Mohamed Daher, Bilal Nakhal · 2024
Sharing of Electronic Medical Records (EMRs) between doctors and medical institutions can now be done using Blockchain - a disruptive approach to the exchange of EMRs. Blockchain can enhance the accuracy of medical decisions and improve public health significantly. However, there is a need to ensure that sensitive information is retrieved from the correct encrypted EMRs, and it is even more difficult to dynamically update the user attributes of authorized users. To this end, we propose a secure data sharing approach that uses blockchain and encryption techniques to ensure secure, efficient, and patient centric data sharing. We came up with a never-before- seen approach to integrate attribute-based encryption, searchable encryption, and robust access control mechanisms to update user attributes with top-notch security measures in place. Additionally, we delve into the hurdles encountered and ways to make amends to the strengths and potential areas for improvement. Our proof of consistency demonstrates the impact of adding a consortium blockchain on securing the shared electronic medical records and the consequential improvements it yields for the healthcare industry.
