CREST [Society 5.0 System Software]
|
This project is the 2021 JST Strategic Creative Research Promotion Project( CREST) Research area, "Creation of basic software for Society 5.0 by fusing basic theory and system basic technology", Toshio Okabe Director) This is the research project "Anonymous healthcare cohort with the guarantee of data privacy and utility".
We aim to establish next-generation anonymously processed data that is theoretically secure against the threat of re-identification and gives a statistical evaluation of errors that occur during processing. Integrated health diagnosis data, healthcare data, and health insurance clain data are used for lifestyle-related diseases. With a mathematical model that predicts the morbidity of injuries and illnesses, it is possible to improve the lives of insured persons, create health strategies in the government, and develop pharmaceutical products at an early stage. |
