Privacy Policy Enforcement Guardrails for Data-Sensitive Retrieval-Augmented Generation

In three linesA PPE framework uses one-class density estimators with fused text embeddings to detect contextual data leakage in RAG systems. The T3+OCSVM detector achieves 0.93+ AUROC, reduces false positives by 44-55 percentage points, and maintains millisecond latency, outperforming supervised MLP classifiers and 14B-parameter LLM judges.
