Abstract

With the increasing popularity of Web-based services, users today have access to a broad range of free sites, including social networking, microblogging, and content sharing sites. In order to offer a service for free, service providers typically monetize user content, selling results to third parties such as advertisers. As a result, users have little control over their data or privacy. A number of alternative approaches to architecting today's Web-based services have been proposed, but they suffer from limitations such as relying the creation and installation of additional client-side software, providing insufficient reliability, or imposing an excessive monetary cost on users. In this paper, we present Priv.io, a new approach to building Web-based services that offers users greater control and privacy over their data. We leverage the fact that today, users can purchase storage, bandwidth, and messaging from cloud providers at fine granularity: In Priv.io, each user provides the resources necessary to support their use of the service using cloud providers such as Amazon Web Services. Users still access the service using a Web browser, all computation is done within users' browsers, and Priv.io provides rich and secure support for third-party applications. An implementation demonstrates that Priv.io works today with unmodified versions of common Web browsers on both desktop and mobile devices, is both practical and feasible, and is cheap enough for the vast majority users.
