Electronic Healthcare Record (EHR) system consists of a patient (or entity acting on behalf of it) sharing his critical medical information with specific people or organizations. Due to the sensitivity of the medical record, a privacy-preserving access control mechanism needs to be in place for building trust among entities including data owner and organizations. Another important metric to be considered is the integrity and accuracy of the outsourced shared medical record. Although existing techniques in the literature tried to address these challenges, however, they are not tolerant of certain types of attacks including collusion, tampering, etc. This research encompasses the proxy re-encryption mechanism and blockchain technology to address the security and privacy concerns of EHR systems. The performance results and security analysis depicts the effectiveness of the scheme to be adopted in practice.
