A Blockchain-Based Secret-Data Sharing Framework for Personal Health Records in Emergency Condition

Abstract

Blockchain technology is the most trusted all-in-one cryptosystem that provides a framework for securing transactions over networks due to its irreversibility and immutability characteristics. Blockchain network, as a decentralized infrastructure, has drawn the attention of various startups, administrators, and developers. This system preserves transactions from tampering and provides a tracking tool for tracing past network operations. A personal health record (PHR) system permits patients to control and share data concerning their health conditions by particular peoples. In the case of an emergency, the patient is unable to approve the emergency staff access to the PHR. Furthermore, a history record management system of the patient’s PHR is required, which exhibits hugely private personal data (e.g., modification date, name of user, last health condition, etc.). In this paper, we suggest a healthcare management framework that employs blockchain technology to provide a tamper protection application by considering safe policies. These policies involve identifying extensible access control, auditing, and tamper resistance in an emergency scenario. Our experiments demonstrated that the proposed framework affords superior performance compared to the state-of-the-art healthcare systems concerning accessibility, privacy, emergency access control, and data auditing.

SmartMedChain: A Blockchain-Based Privacy-Preserving Smart Healthcare Framework

“…In order to preserve patients' privacy, it is of utmost importance to understand how patients' data are stored, shared, used, and managed. Having this in mind, we compare in Table 2 a number of recent works, where some of them [21,23,28,29,31] deal with data storage. In particular, since the Blockchain is a role player in our contribution, it was primordial to consider recent Blockchain-based solutions like [25][26][27][28][29][30][31].…”

By studying these propositions, we can distinguish between the type of data that can be stored in the Blockchain (metadata) and the data that are stored off-chain and generally in the cloud.…”

Health-ID: A Blockchain-Based Decentralized Identity Management for Remote Healthcare

“…The healthcare solutions presented in [21][22][23][24][25][32][33][34] only focus on decentralized healthcare record management systems. These solutions either assume to have a decentralized IdM or rely on a centralized IdM of hospitals.…”

“…An attribute-based signature scheme for multiple users in EHR management is presented in [21], whereas BIoTHR is a novel privacy-preserving IoT-based EHR scheme [33]. In [34], a healthcare management framework is suggested for emergency scenarios that use blockchain technology to ensure access control, authentication, and audibility. Blockchain has enabled an efficient method of data authentication in electronic health records.…”

Blockchain for Secure Medical Records Storage and Medical Service Framework using SHA 256 – Verifiable Key

“…In the current medical data management systems, the medical data shows risk factors such as data loss, hacking of the data from unauthorized users, data security, personal privacy leakage, etc. The medical data which are obtained from medical institutions are centralized in such a manner that it becomes vulnerable to distinct cyber threats such as hacking, malicious tampering that would lead to loss of medical data and data leakage [9]. Therefore, in the present research work, the use of blockchain technology gives an advantage, since it effectively addresses the issues related to security in cloud-based systems that are immutable [10].…”
