# 🔐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

## 🎉 News

- **[2026.06]** 🎊 Our **MultiPriv** has been accepted to **ICML 2026**, and **DualTAP** has been accepted to **ECCV 2026**!
- **[Coming Soon]** 🚀 The **MultiPriv** dataset will be updated after our latest ongoing work is completed.

## 📌 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
