SHARD: cell-keyed residual splitting for alignment-resistant private dense retrieval arXiv:2606.27976v1 Announce Type: new Abstract: Dense embeddings underpin semantic search and RAG, yet a leaked vector store hands much of the underlying text back to whoever holds it. The attacks that make this possible (few-shot alignment, zero-shot inversion, unsupervised cross-space translation) share one weakness: the protected store is a single global geometry that can be aligned to a …
