Blockchain technology for providing an architecture model of decentralized personal health information

Abstract

The personal health information (PHI) is an activity among the health-care providers and the patients in terms of managing the data which is sensitive to the parties. The PHI data have been maintained by multiple health-care providers, thus resulting in separated data. Moreover, the PHI data are stored in the provider's database, hence the patients have no authority to manage their own information. Therefore, in this article, we propose a conceptual model for managing the PHI data which is derived from several health-care providers by relying on the blockchain technology in the peer-to-peer overlay network. In addition, we elaborate the security analysis that might be occurring in the proposed model. By leveraging on our model, it allows the patients and the providers to collect effectively the PHI data onto a single view as well guarantee of data integrity. The blockchain offers an immutable of the data record without having to trust a third party. The experimental results show that the proposed approach is promising to be developed due to the high success rate in terms of data dissemination.

A Systematic Review of Blockchain in Healthcare: Frameworks, Prototypes, and Implementations

“…Most papers analysed did not discuss development strategy, yet a few mentioned their system as either open source or having an Open API or proprietary, and again most did not discuss this as shown in Figure 17. Only the following papers reviewed papers discussed one or more of the following consensus algorithms: Proof-of-Work [27], [31], [38], [40], [41], [44]- [46], [50], [70], [75], [77], [80], [84], [87], [92], [96], [98], [106], [108], [118], [122], [127], Proof-of-Stake [114], [115], [124], [125], Proof-of-Existence [28], Proof-of-Information [62], Delegated-Proof-of-Stake [34], [121], [166], Hybrid-Delegated-Proof-of-Stake [85], [90], Delegated-Proof-of-Work [103], Proof-of-Disease [59], Proof-of-Authority [143], and Proof-of-Familiarity [158].…”

Adoption of blockchain technology in various realms: Opportunities and challenges

“…Blockchain enacts a vital role in the health industries in different aspects and health is an important area is to be concentrated, and that to subfields in health are facing some issues like lack of proper management of personal health information of the individual patients, drugs counterfeiting, and drug supply chain 37 Rahmadika et al 38 propose that personal health information (PHI) architecture is the incorporation of healthcare providers and patients into the same blockchain network collectively. So that patient health information is available in a distributed network.…”

Toward Privacy-Preserving Shared Storage in Untrusted Blockchain P2P Networks

“…A decentralized personal health information model originally came from our previous research [12]. In our predecessor work, blockchain technology is used to manage the personal health information (PHI) data of the patient which obtain from several healthcare providers as can be seen in Figure 6.…”

“…The personal health information of the patient is propagated in the peer-to-peer blockchain network and the data are stored in a storage provider. The model of decentralized healthcare system comes from our previous research [12]. The privacy-preserving for the user is beyond the topic at the time.…”
