Sharing Medical Information on Blockchain
Tokio Marine & Nichido Fire Insurance Co.
“Tokio Marine & Nichido(TMNF) invented a unique and secure method to share medical information on Blockchain in collaboration with Fukuoka City, which is a National Strategic Special Zone and Planetway Corporation, a tech startup with highly secure data communication platform technology.
In Japan, the surge of medical expenses due to aging and lifestyle diseases has become one of the most pressing issues.
Sharing patients’ medical information among medical institutions and related parties will have various advantages such as preventing redundant medical examination, reducing administrative costs, and providing better and faster medical service.
It will also bring positive impacts for insurance companies and its customers such as easy and quick claims payment, prevention of fraudulent claims caused by tampering medical information, etc.,
Blockchain is a partly ideal method to circulate medical information for its cost efficiency, anti-tampering and robustness. On the other hand, there’s still a concern to pack all the highly sensitive medical information into Blockchain because the data itself is not encrypted.
To solve that dilemma, TMNF ,Fukuoka District Committee of Strategy (FDC) and Planetway invented a unique combination of Blockchain and secure data exchange platform. The data exchange technology was originally developed in Estonia and have been used in that country safely for over 15years.
In the pilot system, TMNF send only the information request to hospitals on Blockchain. Hospitals will send the requested information back to TMNF via “avenue-cross”. It’s the world’s first attempt to use Estonian governmental technology in a private sector.
