On the other hand, an electronic health records (EHRs) is the electronically stored health information in a digital format.EHRs are normally shared among healthcare stakeholders and facing power failure, data misuse, lack of privacy and security, and audit trail.

Experimental results and system security analysis show that the system performs search and verification tasks securely and quickly through the network.īlockchain is the revolutionary invention of the twentieth century that offers a distributed and decentralized setting to communicate among nodes in a list of networks without a central authority. In addition, the system uses an interplanetary file system (IPFS) and cloud computing to store patients’ data and files. The system consists of a smart contract that connects to a decentralized user application through which users can transact with the system. The proposed system provides several services: storage, verification, and search. This gap motivated us to develop a system based on blockchain that has several characteristics: decentralization, security, anonymity, immutability, and tamper-proof. This challenge makes it difficult to provide some services in central electronic medical systems, such as file search and verification, although they are needed.
In this paper, solutions to some important practical issues such as incapacitated patients, encryption key forgetting/missing, and efficient interaction of doctors with EHRs sharing scheme are also seriously discussed.Ĭentral management of electronic medical systems faces a major challenge because it requires trust in a single entity that cannot effectively protect files from unauthorized access or attacks. The experimental results showed that (1) EHRs are securely shared under the control of patients and (2) EHR files are retrieved at an acceptable speed supported by IPFS technology. In our experiment, a prototype system is developed to validate the proposed scheme. Since EHR abstracts are encrypted by patients’ public keys, the sharing of EHR files is under the control of patients. In BEAS, the EHR file addresses generated by IEFS are encrypted and saved in EHR abstracts for privacy protection. Secondly, the blockchain is used to implement the blockchain-based EHR abstract system (BEAS) to manipulate EHR abstracts access.

With the high-throughput content-addressed block storage model and appropriate redundant backup of IPFS, IEFS is tamper-resistant and free of a single point of failure.
Firstly, the IPFS-based EHR file system (IEFS) is designed to save and share large-size EHR files among medical institutions. For this purpose, blockchain technologies are combined with interplanetary file systems (IPFS) to provide efficient secure EHRs sharing. The main objective of this study is to propose a controllable secure blockchain-based EHRs sharing scheme. However, institutions are faced with difficulties in privacy protection and efficiently secure data exchange.
The sharing of electronic healthcare records (EHRs) is important to healthcare and medical research. Finally, this work demonstrates a complete architectural implementation (using Hyperledger and a private blockchain network) of the proposed EHR sharing and access controlling by using two levels of chain (two distinct ledgers) that ensures an efficient sharing platform of PHI. Additionally, the data sharing is secured by applying a randomly selected data de-identification method that guarantees integrity and trackability of user data anonymously. This work uses a traditional cloud storage system to store information while saving the indexes of EHRs in a chain to ensure PHI integrity. This study aims to use blockchain technology to build a complete EHR sharing and tracking system, such that even after access is granted to researchers or medical personnel, EHRs remain unaltered and the identities of patients are hidden. Intruders can tamper sensitive protected health information (PHI) or personally identifiable information (PII) purposefully. Electronic health record (EHRs) demands the highest privacy and security as the accuracy of medical research and service largely depend on the integrity of it.
