Our project called "Constructing an infrastructure for secure data sharing and distributing, accelrating integrated bigdata utilization" is 5.5-year national project, which started in 2015. This is a sub-project of "Advanced Core Technologies for Big Data Integration" run by JST CREST.
An infrastructure where providers can trust data on, users can get results from and make use of them trustfully, is required today. We do not relay on "Anonimization" or "Encryption during transmission", and aim to construct an open-source library for data mining which handles data on an encrypted state. We are optimizing it from the aspects of both cryptology and computer architecture, making it more than 1000 times faster than today's scheme.
