Current trend in healthcare industry maintains patient medical information’s in the form of Electronic Health Records (EHR) which leads to data security and privacy issues while sharing. In this paper, we propose blockchain based EHR system with smart contract, hyper ledger and cloud based storage providing high security and privacy for the patients. The fund transactions for doctor appointment, pharmacy, doctor consultant fee can be paid through cryptocurrency using digital signature algorithm. Security is attained using blockchain technique that is each block would contain data, secure index, hash value generated for the respective block and previous block hash value as well making intrusion complex. Thus any intruder tries to access by changing the hash value, this affect the hash values there after making the whole blockchain network invalid. For experimental results, we used ethereum based open source blockchain framework. © 2020 Elsevier B.V., All rights reserved.
