Outline

Anonymization is known as a methodology to allow healthcare bigdata to be ready for provision to data consumers with no risk of infringement of individual’s right and interests. However, it is concerned to disrupt its utility as reliable medical resource by modifying healthcare data too much. To address the issue, we develop a new differential private anonymization with theoretical security guarantee.

Outline

To address or reduce concerns about data sharing including intrusion, data leakage to external systems by (otherwise legitimate) users, and reidentification of personal information by data analytics (intentional or not), we work together across layers ranging from system software (data infrastructure and operating systems) to privacy-preserving data analyses (differential privacy and federated learning) to real applications (medical and trajectory data), thereby contributing to realizing Society 5.0, a society in which we can safely and widely utilize data.

Outline

This project aims to realize secure Internet of Things (IoT) systems in accordance with the concept of zero trust by the fusion of formal verification and system software technologies. In the formal verification research, we provide mathematical proofs for the legitimacy of IoT trust chains and address unknown threats combining static and dynamic verification. In the system software research, we develop mechanisms for isolated execution, automatic detection, and automatic countermeasure in conjunction with the theoretical results in order to demonstrate zero trust IoT. We also promote social acceptance of IoT by ensuring the accountability.

Outline

This project aims to realize “Privacy-centric information infrastructure” that provides network-wide controllability of the information privacy-level to users. Current information infrastructure lacks a mechanism to manage a specific information privacy-level through multiple software components over the network. In this project, we introduce a mechanism called “secure network container” that encapsulate the execution environments connected through the network to process the information in it, and the transfer of the information between the secure network containers are modeled using the type-theory and protected by the secure execution platform.

Outline

This research designs and develops TASK/OS5, an S5 infrastructure software for digitalizing regional communities’ knowledge. The software enables securely sharing and utilizing privacy-sensitive personal data and machine learning models among different individual regional communities. In addition, it has a function to facilitate the participation of older people in the system. The effectiveness of the methodology will be demonstrated through disaster response and traffic improvement scenarios in the regional communities.
