The purpose of this document is to provide a detailed overview of “Health Care Data Sharing (POC) using Corda Blockchain” and its parameters and goals. This document can be used by developers, technical architects, and system reviewers for their reference. Through this document, we will cover the Installation. Once we achieve that, we will cover a “Health Care Data Sharing” use case.
Corda is distributed ledger software for recording and processing shared data such as business contracts. It supports smart contracts, which is an agreement between transacting parties, whose execution is both automatable by computer code, and whose rights and obligations, as expressed in legal prose, are legally enforceable.
Corda is an open-source blockchain platform built for businesses to develop from scratch. Corda blockchain development services enable businesses to transact directly and in strict privacy using smart contracts. As a result, it reduces transaction and record-keeping costs and streamlines business operations.
Corda is a decentralized database platform having the following features.
The adoption of Electronic Health Records (EHR) software is a top priority for any health system CIO, yet it’s astronomically expensive and takes significant time and resources to implement.
The biggest challenge faced by the Healthcare industry is the lack of interoperability not just between different organizations’ software platforms but even within a single health provider/system.
For example: If Fortis Delhi wants to share health records of a patient with Apollo Bangalore OR Medanta Delhi, there is no central system to share the information, at the same time ensuring that patient data is secured.
We provide Electronic Health Records (EHR) software, which is very economical and takes less amount of time and resources to implement.
We provide a central system to share the Health-related information, at the same time ensuring that patient’s data is secured.
Blockchain could enable these different systems to talk to one another and provide a complete holistic patient profile without the need for an intermediary to provide any particular validation. Records could be tracked in an audit-able, time-stamped, and immutable ledger so that no one party could ever fraudulently alter them.
Definitions, Acronyms, and Abbreviations
Notary clusters prevent “double-spends”.
A notary is network service to provide uniqueness consensus attestation for transactions.
The vault contains data extracted from the ledger that is considered relevant to the node’s owner, stored in a relational model that can be easily queried and worked with.
A node’s name must be a valid X.500 distinguished name. In order to be compatible with other implementations (particularly TLS implementations), we constrain the allowed X.500 name attribute types to a subset of the minimum supported set for X.509 certificates (specified in RFC 3280), plus the locality attribute.
The node’s owner interacts with the node solely via remote procedure calls (RPC). The node’s owner does not have access to the node’s ServiceHub.
Corda Nodes communicate with each other using an asynchronous protocol, AMQP/TLS. The only HTTP communication is for the initial registration of each Corda Node, and for sharing of the Corda Node address locations by way of the Network Map. Each client application communicates with Corda Nodes using RPC calls. Aso, the Corda Vault is a database that relies on JDBC connection from the Corda Node.
Currently, we are not able to connect the Spring app with multiple nodes.
