标题： PriveShield: Enhancing User Privacy Using Automatic Isolated Profiles in Browsers

摘要： 在线跟踪是在网络上广泛存在的做法，但其在伦理、安全和隐私方面存在疑问。 尽管网络跟踪可以为互联网用户提供个性化和定制的内容，但它作为一种复杂的监控机制，用于收集广泛的用户信息。 本文介绍了 PriveShield，一种轻量级的隐私机制，在破坏信息收集循环的同时，为互联网用户提供更多控制权以维护其隐私。 PriveShield 作为浏览器扩展实现，提供可调整的隐私功能，使用户能够同时使用多个身份或账户浏览网络，而无需对底层浏览器代码或服务进行任何更改。 在需要时，客户端会自动分析多个因素，以隔离基于在线跟踪的 cookie 和其他信息。 PriveShield 根据用户的浏览历史、与网站的交互以及他们在特定网站上花费的时间为客户创建隔离的个人资料。 这使得用户可以轻松防止不需要的浏览信息被共享给第三方和广告交换，而无需手动配置。 我们的评估结果来自 54 个现实场景，表明我们的扩展在 91% 的场景中能有效防止重新定位广告。 显示英文摘要

摘要： Online tracking is a widespread practice on the web with questionable ethics, security, and privacy concerns. While web tracking can offer personalized and curated content to Internet users, it operates as a sophisticated surveillance mechanism to gather extensive user information. This paper introduces PriveShield, a light-weight privacy mechanism that disrupts the information gathering cycle while offering more control to Internet users to maintain their privacy. PriveShield is implemented as a browser extension that offers an adjustable privacy feature to surf the web with multiple identities or accounts simultaneously without any changes to underlying browser code or services. When necessary, multiple factors are automatically analyzed on the client side to isolate cookies and other information that are the basis of online tracking. PriveShield creates isolated profiles for clients based on their browsing history, interactions with websites, and the amount of time they spend on specific websites. This allows the users to easily prevent unwanted browsing information from being shared with third parties and ad exchanges without the need for manual configuration. Our evaluation results from 54 real-world scenarios show that our extension is effective in preventing retargeted ads in 91% of those scenarios.
