Toshiba Corporation, Tohoku University Tohoku Medical Megabank Organization (ToMMo), Tohoku University Hospital, and the National Institute of Information and Communications Technology (NICT) have demonstrated the world's first personalized healthcare system that stores genome data from many individuals in multiple locations and utilizes them for medical treatment and healthcare using an information theoretically secure method based on the quantum key distribution (QKD) link, the secret sharing system and personal authentication technology. This system is theoretically secure against the threat of store now and decrypt later attacks, prevents data leaks, falsification, and loss of genome data. In this system, data decryption and reconstruction are performed by using personal authentication and individual consent. The system is expected to contribute to the realization and spread of personalized healthcare.
