Vid-SME: Membership Inference Attacks against Large Video Understanding Models
Vid-SME computes Sharma-Mittal entropy differences between natural and reversed video frame sequences to infer training membership in video understanding LLMs, but its effectiveness is confounded by member/non-member dataset distribution shifts.
