$\pi$-RAG: Oblivious Retrieval via Semantic Quantization and Transcendental Addressing for Large Language Models
Researchers introduce π-RAG, a novel retrieval architecture that protects sensitive data in Large Language Models by using the digits of pi as an oblivious indirection layer, eliminating direct exposure of vector embeddings to inversion attacks. The system combines semantic quantization with cryptographic salting to enable privacy-preserving retrieval for compliance-heavy sectors like finance and healthcare.
