    提出 IDUnlearn-Bench,评测 VLM 个体级遗忘后的身份残留

    Published
    Evaluated models
    Qwen3-VL-2B, Qwen3-VL-4B, Qwen3-VL-8B and others6
    AbstractIDUnlearn-Bench 用四族探针显示:压低直接属性访问后,身份仍常能被反向查出、绑定或重构。

    IDUnlearn-Bench 评测 VLM 是否忘掉一个可跨模态识别的人,而不只是答不出某条监督事实。

    QPriv-VL:面向视觉语言模型的问题引导 token 裁剪隐私防御

    提出 QPriv-VL,用问题引导剪枝降低分布式视觉问答的隐私泄露

    Published
    Evaluated models
    LLaVA-1.5-7B, Llama-2
    AbstractQPriv-VL 在切层前按问题相关度与 DINOv2 敏感度剪视觉 token,作者称能在约四成 token 下兼顾准确率与四类攻击。

    QPriv-VL 把问题引导的视觉 token 剪枝做成分布式 VQA 的客户端隐私防御,而不是只做集中式推理加速。

    Evaluated models
    GTR-T5 encoder, DPR
    AbstractSHAQ replaces document embeddings with shadow query embeddings.

    SHAQ is a defense against EIA for cloud vector databases: instead of directly modifying document embeddings, it replaces them with shadow query embeddings.

    研究者提出针对微调 TTS 模型的黑盒成员推断攻击

    提出针对微调 TTS 的黑盒成员推断攻击

    Published

    Black-box
    Evaluated models
    CosyVoice2, F5-TTS, XTTS-v2
    Abstract黑盒 TTS 成员推断以 recitation 加分层语音表示为分数,说话人级强于记录级,DP-SGD 可压到随机附近。

    作者给出一个针对微调文本转语音模型的黑盒成员推断框架,分别审计说话人是否进入微调集,以及某一条文本–音频记录是否进入微调集。微调 TTS 以合成文本和参考语音双条件生成,既有生成模型 MIA 的单条件查询和图像/文本上的逐点比较不能直接套用。作者用 scorable extent 与 memorization elicitation 比较五种查询,认为只有 recitation(用目标转写和干净目标语音要求模型复现)同时满足两条,并把它作为主查询。

    Aegis: Governance, Integrity, and Security for AI Voice Agents

    提出 Aegis 红队框架,多轮攻击高风险语音 Agent

    Published
    Setting
    AI Agent
    Evaluated models
    GPT-4o, GPT-4o-mini, Gemini-1.5 Pro and others7
    AbstractAegis red-teams three types of voice agents: query-based access eliminates authentication and leakage successes, but behavioral attacks remain.

    Aegis uses multi-turn red-teaming evaluation on ALLM voice agents already integrated into business systems. The authors call this the first systematic red-teaming framework in this setting.
