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.
Highlights
The Healthcare management system has traditionally been involved with information exchange between patients, business entities such as different hospital systems, pharmaceutical companies, etc
In the traditional emergency system, the personal health record (PHR) access permission should be inquired from one or a number of trustworthy individuals, where an emergency condition occurs, i.e., it takes much time for contacting such persons. We solve this issue by defining security policies that a patient can assign which type of users can access the PHR without requiring any inquiry from other persons. To address such obstacles and ensure the reliability of PHR, we propose a novel management system based on a blockchain network [13,14] that leverages the shared and changeless distributed ledger
Does the proposed model provide a secure access control system for PHR data in emergency condition? To answer this question, we applied the Hyperledger Composer based on Hyperledger Fabric, which affords some permissions for participants that allow limited access during an emergency condition
Summary
The Healthcare management system has traditionally been involved with information exchange between patients, business entities such as different hospital systems, pharmaceutical companies, etc. The use of blockchain technology in healthcare management system can provide five mechanisms including: (i) patient identity, (ii) data aggregation, (iii) data liquidity, (iv) digital access rules, and (v) data immutability, which might address such challenges [1,2,3]. Several management systems exist for healthcare, which controls PHR, incredibly delicate data such as PHR entities [1,2,3]. A PHR is a mechanism for digitally storing a patient’s health data. It needs to allow appropriate access control for manage, track, and restrict their health data [4]
