OneSwarm is a new peer-to-peer tool that provides users with explicit control over their privacy by letting them determine how data is shared. Instead of sharing data indiscriminately, data shared with OneSwarm can be made public, it can be shared with friends, shared with some friends but not others, and so forth. We call this friend-to-friend (F2F) data sharing. OneSwarm is:

1. Privacy preserving: OneSwarm uses source address rewriting to protect user privacy. Instead of always transmitting data directly from sender to receiver (immediately identifying both), OneSwarm may forward data through multiple intermedaries, obscuring the identity of both sender and receiver. For more details, check out the OneSwarm overview screencast or our papers.
2. User friendly: OneSwarm's interface is web-based and supports real-time transcoding of many audio and video formats for in-browser playback, eliminating the need for casual users to master a new application's interface or search for custom media codecs.
3. Open: OneSwarm is freely available and built on existing standards. OneSwarm can operate as a fully backwards compatible BitTorrent client, and its friend-to-friend data sharing features are built on cryptographic standards, e.g., X.509 certificates and SSL encryption.

Although OneSwarm is backwards compatible with existing BitTorrent clients, it cannot anonymize transfers with them. OneSwarm only preserves user privacy when sharing files using the friend-to-friend network.

Internet Explorer doesn't support many of the browser features that OneSwarm requires. OneSwarm works well with Firefox, Chrome, Safari, and Opera.

Strong anonymity requires that an adversary with the capability to eavesdrop on every network packet be unable to recover information about data transmitted. In the case of OneSwarm, such an adversary would be able to correlate the increase in traffic between sender and receiver along an overlay path. Of course, monitoring the entire Internet is beyond the abilities of most monitoring agents, and OneSwarm is intended only to improve privacy relative to existing P2P networks that unambiguously broadcast user behavior. OneSwarm users should trust their directly connected friends and can expect privacy relative to the wholesale monitoring of P2P networks that is common today, but a capable monitoring agent (e.g., law enforcement or government) may be able to infer behavior.
