项目摘要

Advertising now funds most of the popular web sites and internet services: companies often provide their services for free, in exchange for collecting data from their users as they interact with the service. In recent years, the scale and resolution of user data that platforms collect has led to a dramatic increase in the variety of targeting, reporting, measurement, and tracking mechanisms that platforms offer to advertisers. Unfortunately, our understanding of the privacy and societal risks of these mechanisms has not kept pace with this increase, raising scientific questions about how much advertisers can learn about platform users through these mechanisms, as well as about their potential for acting in a biased or discriminatory way. Because anyone on the Internet can sign up to be an advertiser on all of these platforms -- granting access to these mechanisms and data at very low cost -- understanding their implications is a critical need. The goal of this project is to improve privacy for all users, and raise awareness among users and regulators of the extensive -- and often hidden -- advertising ecosystem that underlies today's popular services, and the privacy and societal risks it poses.This project is following a three-pronged research agenda. The first set of research tasks centers on enhancing privacy, addressing the problem of revealing advertising statistics while providing strong guarantees of user privacy based on methods from the field of differential privacy. The second set of research tasks focuses on detecting and preventing discrimination, addressing the multitude of ways in which the advertising platforms' features could inadvertently or intentionally discriminate against different groups through the choice of which ads to display to which users. The third set of research tasks addresses issues of transparency and control, studying whether current transparency practices are comprehensive and truthful from both users' and regulators' perspectives, and whether the provided control features have the expected effects on ad delivery and align with people's expectations of privacy.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

广告现在为大多数流行的网站和互联网服务提供资金：公司通常免费提供服务，以换取在用户与服务交互时收集用户的数据。近年来，平台收集的用户数据的规模和分辨率导致平台向广告商提供的各种定位，报告，测量和跟踪机制急剧增加。不幸的是，我们对这些机制的隐私和社会风险的理解并没有跟上这种增长的步伐，这就提出了一个科学问题，即广告商可以通过这些机制了解平台用户多少，以及他们以偏见或歧视性方式行事的可能性。因为互联网上的任何人都可以注册成为所有这些平台上的广告商-以非常低的成本获得这些机制和数据-了解它们的含义是一个关键的需求。该项目的目标是改善所有用户的隐私，并提高用户和监管机构对当今流行服务背后的广泛（通常是隐藏的）广告生态系统及其带来的隐私和社会风险的认识。该项目遵循三管齐下的研究议程。第一组研究任务集中在增强隐私，解决揭示广告统计数据的问题，同时基于差异隐私领域的方法提供强有力的用户隐私保证。第二组研究任务侧重于发现和预防歧视，解决广告平台的功能可能通过选择向哪些用户显示哪些广告而无意或有意歧视不同群体的多种方式。第三组研究任务涉及透明度和控制问题，从用户和监管机构的角度研究目前的透明度做法是否全面和真实，以及所提供的控制功能是否对广告投放产生预期效果并符合人们对隐私的期望。该奖项反映了NSF的法定使命，并且通过使用基金会的评估被认为值得支持知识价值和更广泛的影响审查标准。
