Demonstration of Secure Data Backup of Medical Records Using Secret Sharing on Secure Communications Network

  The National Institute of Information and Communications Technology (NICT, President: Hideyuki Tokuda, Ph.D.), Kochi Health Science Center (KHSC, Director: Yasuhiro Shimada) and collaborating teams have developed a secure data backup system in an 800 km network connecting the data servers in Kochi, Osaka, Nagoya, Otemachi and Koganei, Japan, using secret sharing and secure communications technologies, and demonstrated distributed storage of medical records and prompt restoration of important items, such as prescription records and allergy information, via a satellite link within a time as short as 9 sec. 

  This technology would be useful for medical support in disaster situations as well as sharing and cross referencing medical records between various hospitals in ordinary situations. 

  The results will be presented in the session of quantum communication on December 16 in the EU-USA-Japan International Symposium on Quantum Technology 2019 held in Kyoto, Japan.
