Data leakage in electronic health records could result in the compromise of patient privacy. Generally, data in EHRs remain unchanged once they are uploaded to the decentralized system, and thus, blockchain can be potentially used to facilitate the sharing of medical data. Different participating medical organizations and individuals can then access Electronic Health Records (EHRs) stored on the blockchain with a higher level of confidence. To develop a scalable lightweight framework based on blockchain technology to ensure data security, patient privacy, scalability, and integrity of the E-healthcare data. The sensitive data to be stored are hashed using the Enhanced Merkle tree (EMT) data structure to provide a digital fingerprint and the hashed values are stored in the blockchain. Encryption of sensitive data is highly important to ensure data privacy for the patients. In this work, an efficient lightweight fast and ideal lattice-based cryptography with Homomorphic Proxy Re-Encryption scheme is utilized to encrypt the sensitive data prior to storing it in the blockchain. Here a blockchain based searchable encryption scheme for EHRs is proposed. The index for EHRs is constructed through complex logic expressions and stored in the blockchain, so that a data user can utilize the expressions to search the index. As only the index is migrated to the blockchain to facilitate propagation, the data owners have full control over who can see their EHRs data. The use of blockchain technology ensures the integrity, anti-tampering, traceability of EHRs’ index. Finally, the performance of the proposed scheme is evaluated, and the Proof of Work (PoW) consensus mechanism is followed to authenticate the new changes that are requested to be made to the data by different stakeholders.
