Trans-RAG: Mathematically Isolated Vector Spaces Enable Secure Cross-Organizational RAG

arXiv·high signal

Liu, Peng, and Zhang introduce a 'vector space language' paradigm where each organization's knowledge exists in a mathematically isolated semantic space, solving the fundamental tension between security, accuracy, and efficiency in cross-org RAG deployments. Unlike encryption approaches that expose plaintext during decryption or federated architectures that prevent resource integration, Trans-RAG maintains isolation throughout the retrieval process. Actionable for enterprise teams building multi-tenant or cross-organizational RAG systems.
