HonestChain: Consortium blockchain for protected data sharing in health information systems

Abstract

Healthcare innovations are increasingly becoming reliant on high variety and standards-compliant (e.g., HIPAA, common data model) distributed data sets that enable predictive analytics. Consequently, health information systems need to be developed using cooperation and distributed trust principles to allow protected data sharing between multiple domains or entities (e.g., health data service providers, hospitals and research labs). In this paper, we present a novel health information sharing system viz., HonestChain that uses Blockchain technology to allow organizations to have incentive-based and trustworthy cooperation to either access or provide protected healthcare records. More specifically, we use a consortium Blockchain approach coupled with chatbot guided interfaces that allow data requesters to: (a) comply with data access standards, and (b) allow them to gain reputation in a consortium. We also propose a reputation scheme for creation and sustenance of the consortium with peers using Requester Reputation and Provider Reputation metrics. We evaluate HonestChain using Hyperledger Composer in a realistic simulation testbed on a public cloud infrastructure. Our results show that our HonestChain performs better than the state-of-the-art requester reputation schemes for data request handling, while choosing the most appropriate provider peers. We particularly show that HonestChain achieves a better tradeoff in metrics such as service time and request resubmission rate. Additionally, we also demonstrate the scalability of our consortium platform in terms of the Blockchain transaction times.

A Comprehensive Survey on Pandemic Patient Monitoring System: Enabling Technologies, Opportunities, and Research Challenges

“…For example, the work proposed in [ 93 ] proposed a blockchain-based secure framework to access and share the medical images in a transparent manner among the patients. A consortium blockchain-based system “HonestChain,” was also proposed in [ 101 ] that ensures auto-assurance and auto-auditability. Interoperability : Blockchain allows different organizations to share data easily and securely.…”

“…Finally, the research results are published on the blockchain for the benefit of doctors worldwide. A consortium blockchain-based system “HonestChain,” was proposed in [ 101 ] that ensures auto-assurance and auto-auditability. It is equipped to ensure distributed trust by calculating requester Reputation and Provider Reputation.…”

Design and Development of A Blockchain-Based Financial Aid Distribution System

“…The HonestChain solution uses consortium blockchain to enable secure data sharing amongst health information systems in the healthcare industry [24]. Experiments and simulations show that this method improves data security and privacy while meeting regulatory requirements.…”

“…[24] examines data accountability and provenance tracing, emphasizing the advantages of consortium blockchain technologies in terms of automating these procedures and guaranteeing data integrity. The proposed architecture offers a decentralized, transparent, and secure alternative for data management, with implications for the government, banking, and healthcare industries that need to monitor data provenance and accountability [24]. In addition, the authors [24] discuss the difficulties associated with data management in smart grids and suggest a consortium blockchain as a decentralized, transparent, and safe platform.…”
