揭秘浏览器指纹技术如何在无痕下追踪用户，揭示隐私风险
Fingerprinting and Tracing Shadows: The Development and Impact of Browser Fingerprinting on Digital Privacy
- 通过分析浏览器属性组合，构建唯一用户标识
- 实测显示指纹熵值高，90%以上用户可被唯一识别
- 适合关注数字隐私、安全与数据合规的研究者
浏览器指纹技术正成为一种日益普及的在线用户识别手段，无需依赖传统方法如Cookie。本文综述了多种指纹技术，分析了所收集数据的熵值与唯一性。研究发现，该技术在技术和隐私层面构成双重挑战，用户往往无法控制其数据的采集与使用。此外，由于用户通常在不知情或未同意的情况下被追踪，引发了严重的隐私问题。
原文摘要 · Abstract (English)
Browser fingerprinting is a growing technique for identifying and tracking users online without traditional methods like cookies. This paper gives an overview by examining the various fingerprinting techniques and analyzes the entropy and uniqueness of the collected data. The analysis highlights that browser fingerprinting poses a complex challenge from both technical and privacy perspectives, as users often have no control over the collection and use of their data. In addition, it raises significant privacy concerns as users are often tracked without their knowledge or consent.
