摘要：In the initial days of the netting, content was designed and hosted by a single person, group, or organization. But these days’ webpages are increasingly composed of content from countless unrelated “third-party” websites in the business of advertising, analytics, social networking, and more. Third-party services have tremendous value: they support free content and facilitate web innovation. But third-party services come at a privacy cost: researchers, civil society organizations, and policymakers have increasingly called attention to how third parties can track a user’s browsing activities across websites. This paper surveys the current policy debate surrounding third-party web tracking and explains the relevant technology. It also presents the Fourth-Party web measurement platform and studies we have conducted with it. Our aim is to inform re-searchers with essential background and tools for contributing to public understanding and policy debates about web tracking.
