| # 🔐MultiPriv: A Multilingual & Multimodal Dataset of PII Entities and Prompts for LLM Privacy Risk Research
|
|
|
| 多语言多模态 PII 实体与 Prompt 数据集 —— MultiPriv 数据集（面向大模型的隐私风险研究）
|
|
|
| ❗Due to the limitations of open-source certificates, attribute-level VLM images cannot be directly published in the repository. We will provide links to each image used in our dataset
|
| 由于开源证书限制，属性级 VLM 图像无法直接公布在仓库里，我们会整理我们数据集用到的每一张图片链接

|
| ## 📌 Overview | 数据集简介
|
|
|
| **MultiPriv** is a multilingual (Chinese & English) and multimodal (text & image) dataset containing extensive **personally identifiable information (PII)**. It is built to support research on **privacy recognition**, **privacy-preserving generation**, and **privacy risk evaluation in LLMs**.
|
|
|
| This dataset includes:
|
|
|
| - Structured annotations of PII entities in text (English & Chinese)
|
| - Image samples with visual privacy information (e.g., faces, ID numbers, license plates)
|
| - Prompt-based user inputs embedding privacy risks, constructed to simulate real-world LLM usage
|
|
|
| **MultiPriv** 是一个包含大量 **个人身份识别信息（PII）** 的中英文、多模态隐私数据集，旨在支持以下研究任务：
|
|
|
| - 文本与图像中的 PII 实体识别
|
| - 隐私感知的文本/图像生成任务
|
| - 大模型中的隐私泄露风险建模与评估
|
| - Prompt 注入与红队测试等安全性研究
|
