Researchers introduce ConfusionPrompt, a privacy framework for large language models that decomposes user prompts into smaller sub-prompts mixed with pseudo-prompts before sending to cloud servers. The method protects user privacy while maintaining higher utility than existing perturbation-based approaches and works with existing black-box LLMs without modification.
Researchers introduce SHRED, a machine unlearning method for large language models that removes memorized private or copyrighted data without requiring a curated retain set of examples. By selectively demoting logits of high-information tokens while preserving model utility through self-distillation, SHRED achieves superior trade-offs between forgetting efficacy and performance compared to existing retain-set-dependent approaches.
Researchers introduce a sequential unlearning framework that enables Large Language Models to forget sensitive data while maintaining performance, addressing GDPR compliance and the Right to be Forgotten in politically sensitive deployments. The method stabilizes general capabilities through positive fine-tuning before selectively suppressing designated patterns, demonstrating effectiveness on the SemEval-2025 benchmark with minimal accuracy degradation.
Researchers formalize privacy-preserving communication for LLM agents by introducing Information Sufficiency (IS) as a framework and proposing free-text pseudonymization as a third privacy strategy alongside suppression and generalization. Evaluation across 792 scenarios reveals that pseudonymization offers superior privacy-utility tradeoffs, and that multi-turn conversational testing exposes significant privacy leakage missed by single-message assessments.
