“…As public blockchain networks utilise identities based on pseudonyms, it is challenging to establish and control the identities of participants. Enterprise blockchain networks, also known as permissioned blockchains, are being developed to cater to enterprise use cases (Emmadi et al, 2019). Permissioned blockchain systems are controlled by a quorum of organisations and, as a result, are classified as semi-decentralised.…”

“…However, the use of a shared ledger in blockchain technology serves to promote transparency, which may be seen as a polar opposite to privacy. A goal of permissioned blockchain technology is, therefore, to attempt a balance between privacy and transparency (Emmadi et al, 2019). Private blockchain systems are classified as centralised since they are largely owned and operated by a single organisation.…”

“…The conventional model employed by EHR systems can no longer ensure the security and privacy of patient health records (Kshetri & Carolina, 2018). The privacy and security of EHRs may be improved by the desirable features of blockchain technology such as decentralisation, immutability, auditability, and transparency (Emmadi et al, 2019).…”

The centralised architecture employed by electronic health records (EHRs) may constitute a single point of failure. From the perspective of availability, an alternative cloud-based EHR infrastructure is effective and efficient. However, this increased availability has created challenges related to the security and privacy of patients’ medical records. The sensitive nature of EHRs attracts the attention of cyber-criminals. There has been a rise in the number of data breaches related to EHRs. The infrastructure used by EHRs does not assure the privacy and security of patients’ medical records. Features of blockchain platforms, such as decentralisation, immutability, auditability, and transparency, may provide a viable means of augmenting or improving services related to the security of EHRs. This study presents a series of experimental data flow configurations to test the application of blockchain technology to aspects of EHRs. The insights gained from these experiments are founded on a theoretical base to provide recommendations for applying blockchain technology to services related to the security of EHR infrastructure. These recommendations may be employed by developers when redesigning existing EHR systems or deploying new EHR systems.

Enterprise business transactions have both public and private information; hence blockchain adaptation to an enterprise business application needs current blockchain platforms to support both public and private information. Public blockchains (permissionless) are optimized for transparency; hence the sharing of private and sensitive information is challenging. On the other hand, private blockchains (permissioned) separate information about a transaction by generating a public transaction and a set of private transactions and treat them separately. This separation weakens the cohesiveness of transaction information and develops an extra burden when it is necessary to connect both public and private information which is not duly addressed in the literature. For example, auditing, regulatory activities, certifications, and traceability need both the public and private information about transactions. This paper uses semantic triples and introduces the Triples for Transactions(T4T) model to define blockchain transactions, improve cohesiveness and resolve the extra burden of connecting both private and public transactions. This paper presents a user-driven transaction analysis, transaction modelling using the T4T model, semantic querying, and REST endpoints to enrich transaction management. Sets of semantic triples can define both public and private information about a transaction while preserving cohesiveness of the information. This approach supports point-to-point sharing of sensitive information while preserving implicit relationships between both private and public information. We have implemented an auditing scenario in the proposed approach adopting Hyperledger Fabric and compared for performance with Hyperledger Fabric. The results showed that the proposed approach reduces the number of transaction cycles by 66% compared to Hyperledger Fabric and the performance of information retrieval is in O(N). This result is a significant improvement compared to Hyperledger Fabric.
