Trans-RAG: Query-Centric Vector Transformation for Secure Cross-Organizational Retrieval
Trans-RAG uses multi-stage query transformations to retrieve from mathematically isolated per-organization vector spaces, achieving 89.90° angular separation, 99.81% isolation, and only 3.5% nDCG@10 drop versus homomorphic encryption baselines.
