Cross-modal linkage risk in clinical vision-language models
Researchers discovered that vision-language models trained on paired chest X-rays and medical reports can re-link de-identified images to their original reports through embedding similarity, creating a privacy vulnerability. The team demonstrated this risk scales with model specialization and developed a differential privacy technique that reduces re-linkage by 62% while preserving diagnostic utility.
