COVID-19 Immutable Test Results Submission and Visualization

Test data reporting by various labs, agencies, and test manufacturers, who enable results collection, is done through various means today – subject to omissions and duplication caused by human and network errors, risks to data integrity, etc. This lowers the trust in the completeness, integrity, and accuracy of the reported data, and the mitigation efforts that rely on it.  As testing moves beyond the controlled environment of medical labs to work places, colleges and universities, airports, sports venues, etc. these challenges become even stronger – introducing additional risks of identity fraud, data tampering, improper PII handling, etc.

COVID-19 immutable test results submission and visualization solution using a distributed ledger technology deployed via a permissioned enterprise blockchain and fronted with a REST API gateway can solve a number of key issues in the current results submission methods and provides the key enablers for mitigating the challenges of At-Anywhere diagnostics. 

A proposed solution design utilizes a DLT provided via a permissioned enterprise blockchain framework based on Linux Foundation’s open source Hyperledger Fabric deployed in FedRAMP-certified Oracle Government Cloud, extended with API gateway to provide easy-to-use REST APIs and web/mobile app for file-based submission, and integrated with rich data analysis and visualization capabilities based on real-time streaming of blockchain transactions to a database with rich analytics capabilities. This solution enables real-time reporting of individual and batched results in a trackable manner with confidentiality, integrity of identity and data, and immutability of the distributed ledger technology. It can also protect PII by anonymizing it using salted one-way SHA2 hashes and enabling self-sovereign user access control to PII information.

By using open source permissioned blockchain network the solution enables decentralization across many test administration venues and test manufacturers, supports multi-vendor/multi-cloud interoperability and scale-out for vendor diversity and enables trust and transparency in open data and open government.
