White Paper on AI Spaces with Fraunhofer ISST and the University of Tokyo
April 21, 2026
Many of today’s industrial and societal challenges cannot be resolved using the information held by any single organization. Responding to demand fluctuations in supply chains, accelerating product development in manufacturing, enhancing diagnostic support in healthcare, and optimizing operations in next-generation smart buildings—all of these require the secure, sovereignty-preserving utilization of data and knowledge distributed across multiple organizations.
We therefore propose AI Spaces as a framework that enables AI systems to collaborate across organizational boundaries while taking into account the real-world constraints of data sovereignty, confidentiality, regulation and misaligned incentives.
Fujitsu is pursuing the development of technologies to enable companies to utilize data and AI models safely in Data Spaces. We will also collaborate with universities and partners to conduct experiments and make proposals to relevant standardization bodies.
