穿普通黑T恤，加热后自动变出骗过摄像头的隐形图案
Thermally Activated Dual-Modal Adversarial Clothing against AI Surveillance Systems
- 用温变染料+柔性加热片，在衣物表面生成可动态激活的对抗性图案
- 50秒内完成激活，对可见光与红外双模态检测成功率超80%
- 适合注重隐私的普通人，让反监控像换衣服一样自然
对抗性补丁已成为抵抗人工智能监控的流行隐私保护方法，但其显眼外观难以在真实场景中部署。本文提出一种热激活的对抗性可穿戴设备，确保在复杂现实环境中具备适应性和有效性。系统结合热致变色染料与柔性加热单元，在衣物表面生成视觉动态的对抗性图案。默认状态下，衣物呈现为普通黑色T恤；通过内置加热装置升温后，隐藏的对抗性图案被激活，使穿戴者能有效规避可见光与红外双模态检测。物理实验表明，该可穿戴设备可在50秒内实现快速纹理激活，并在多种真实监控环境下保持超过80%的对抗成功率。本工作展示了一条面向物理实体、用户可控的抗AI系统新路径，凸显了主动式对抗技术在无处不在的AI监控时代对隐私保护的重要性。
原文摘要 · Abstract (English)
Adversarial patches have emerged as a popular privacy-preserving approach for resisting AI-driven surveillance systems. However, their conspicuous appearance makes them difficult to deploy in real-world scenarios. In this paper, we propose a thermally activated adversarial wearable designed to ensure adaptability and effectiveness in complex real-world environments. The system integrates thermochromic dyes with flexible heating units to induce visually dynamic adversarial patterns on clothing surfaces. In its default state, the clothing appears as an ordinary black T-shirt. Upon heating via an embedded thermal unit, hidden adversarial patterns on the fabric are activated, allowing the wearer to effectively evade detection across both visible and infrared modalities. Physical experiments demonstrate that the adversarial wearable achieves rapid texture activation within 50 seconds and maintains an adversarial success rate above 80\% across diverse real-world surveillance environments. This work demonstrates a new pathway toward physically grounded, user-controllable anti-AI systems, highlighting the growing importance of proactive adversarial techniques for privacy protection in the age of ubiquitous AI surveillance.
