Executive Summary

The widespread adoption of social plugins, such as Facebook's Like and Google's +1 buttons, has raised concerns about their implications to user privacy, as they enable social networking services to track a growing part of their members' browsing activity. Existing mitigations in the form of browser extensions can prevent social plugins from tracking user visits, but inevitably disable any kind of content personalization, ruining the user experience. In this paper, the authors propose a novel design for privacy-preserving social plugins that decouples the retrieval of user-specific content from the loading of a social plugin.
