PI-SAFE: Practical Privacy-Preserving LLM Inference With Adversarial Fine-Tuning for Optimized Utility

Cloud-based Large Language Model (LLM) inference services typically require users to submit plain-text inputs, thereby posing severe privacy risks. Existing privacy-preserving paradigms are mostly task-specific and often necessitate pervasive modifications to the entire server-side model. This reliance introduces subst...

Spectrum-Aware Bounds on Invertibility for Privacy-Enhancing Instance Encoding

A family of new bounds that are tighter, applicable even to fully deterministic encoders, and applicable even to fully deterministic encoders can extend beyond MSE to other norm-based similarity metrics, by properly accounting for the encoder's spectral structure.
