New privacy defense prunes visual tokens for LLMs

Researchers have developed QPriv-VL, a novel framework designed to enhance privacy in Vision-Language Models (VLMs) used in sensitive applications like Federated Learning. This system intelligently prunes visual tokens before transmission, reducing both data transfer costs and the risk of exposing private information. QPriv-VL uses a Dynamic Threshold Predictor (DTP) that considers question relevance and feature sensitivity to selectively retain important visual data while suppressing potentially sensitive regions, achieving competitive accuracy with significantly fewer transmitted tokens.

    Don't Send What You Don't Need: Question-Guided Token Pruning as a Privacy Defense for Vision-Language Models

    arXiv:2609.15671v1 Announce Type: cross Abstract: Visual Question Answering (VQA) with Vision-Language Models (VLMs) is increasingly used in privacy-sensitive and bandwidth-constrained settings. Federated Learning (FL), Split Learning (SL), and U-Shaped Split Learning (USL) keep …
