Project Information
Project Title: JST CREST “Creation of Fundamental Software for Society 5.0 through the Fusion of Basic Theories and System Platform Technologies”
Research Theme: “Trusted Inter-Reality Infrastructure for Safely Creating and Connecting Diverse Forms of Realities”
Principal Investigator: Takuro Yonezawa (Nagoya University)
Co-Investigators: Akira Kanaoka (Toho University), Takayuki Aoki (Kadinche Co., Ltd.), Manabu Tsukada (The University of Tokyo)
Project Duration: 5.5 years (FY2022–FY2028)
Development Goals and Overall Vision of the Internet of Realities Project
Information technologies have expanded our “realities” (the spaces where we place our sense of life’s value) from the physical world into cyber and virtual spaces. In recent years, advanced Virtual Reality (VR) technologies directly linked to human senses have emerged one after another, opening possibilities for new industries. However, in exchange for their high immersion, these technologies raise serious concerns about security and privacy risks related to biometric and environmental data captured by constantly worn VR devices, as well as potential invasive attacks on both body and mind.
This project aims to establish an information infrastructure that enables the safe and reliable integration of diverse forms of realities—comprising various physical and virtual spaces and the entities within them.
First, we will identify the requirements for a new trust foundation in extended realities, taking into account spatial properties and user attributes, through R&D on technologies for constructing and connecting realities across multiple modalities.
This includes not only expanding security perspectives such as identity assurance, authentication, and adaptable encryption methods with variable granularity, but also medically examining physiological and psychological risks caused by the invasiveness of wearable devices (Note 2), and designing a human-centered usable security (Note 3) infrastructure suited for real-world operation.
The integrated infrastructure from these research areas is called the “Trusted Inter-Reality Platform,” and its convenience, safety, and availability will be evaluated through domestic and international field trials.
Note 1) Trust Principle: The conventional CIA (Confidentiality, Integrity, Availability) security triad is extended to CCA (Confidentiality, Consistency, Availability) as the foundational principle of trust in Inter-Reality.
Note 2) Wearable Devices: Devices worn on the human body that stimulate the five senses. These include VR goggles that enhance audiovisual immersion and haptic devices providing tactile feedback.
Note 3) Usable Security: Security technologies designed for high usability—lightweight, accessible, and user-friendly.
