Spruce system enables faster, private outsourced retrieval for large document collections

By PulseAugur Editorial · [1 sources] ·

Researchers have developed Spruce, a novel system designed to enable scalable and private outsourced retrieval for large document collections. Spruce co-designs data representations with cryptographic protocols, utilizing compact binary codes and efficient Hamming-distance computations under two-server multi-party computation. This approach significantly reduces the computational and communication overhead compared to traditional methods, achieving speeds up to 22.9 times faster while preserving retrieval quality. AI

IMPACT This system could significantly improve the efficiency and privacy of RAG applications that rely on outsourced vector databases.

    Spruce: Scalable Private Outsourced Retrieval Using Compact Embeddings

    Retrieval-Augmented Generation (RAG) has made dense retrieval over large document collections a standard building block. Organizations increasingly outsource vector indexes to untrusted clouds, exposing proprietary corpora and user queries. Cryptographic protection is challenging…
