Engineers develop capabilities for more secure blockchain applications

Vanderbilt engineers have successfully developed and validated the feasibility of blockchain-based technologies for secure, confidential sharing of patient medical records in a case study that demonstrates how blockchain could solve a huge healthcare challenge.

Health IT interoperability has been an elusive goal, with data silos between hospitals, clinics, pharmacies, and payers making exchange of information difficult. The Vanderbilt case study shows how  tech could securely streamline the process.

Significantly, researchers also are partnering with a Nashville company that plans to use blockchain technology to tackle the nation’s opioid addiction crises.

These developments are part of a larger effort at Vanderbilt’s Institute for Software Integrated Systems to approach the problems and promise of blockchain in a holistic way. Researchers have created a range of significant capabilities, including an architecture that supports secure information access to design standards for best practices, mathematical verification that the underlying code is correct, and a test bed for researchers to try out their ideas.

In addition to healthcare, they are working on blockchain test cases with smart, connected cities, power grid applications, and supplier risk management.
