We have established the General Incorporated Association AI Data Sovereignty Co-creation Organization (CODAS). CODAS aims to realize a society where individuals and organizations can enjoy the benefits of AI while maintaining data sovereignty and co-creating. It operates in three layers: research, standardization, and social implementation.
CODAS, the AI Data Sovereignty Co-Creation Organization, will speak at AWS Summit Japan 2026 on the theme of privacy-preserving AI and data sovereignty. The presentation will introduce a technology stack that co-creates AI while maintaining privacy, showcase real-world application examples, and a demo of a reference implementation will also be displayed at the venue.
