Privacy-preserving P2P data sharing with OneSwarm

Privacy--the protection of information from unauthorized disclosure--is increasingly scarce on the Internet, and yet increasingly important as every user becomes both a content consumer and a content producer. The lack of privacy is particularly true for popular peer-topeer data sharing applications, where public rendezvous and dynamic membership mean that user behavior can be easily monitored. In this paper, we describe the design, implementation, and experience with OneSwarm, a new P2P data sharing system that provides users with explicit, configurable control over their data: data can be shared publicly or anonymously, with friends, with some friends but not others, or only among personal devices. OneSwarm is publicly available and has been downloaded by hundreds of thousands of users in the few months since its release. A key goal is to reduce the performance cost of privacy and our measurements of the live system show that anonymized data transfers are performance competitive wit...
