Editing Free Haven Project

The '''Free Haven Project''' was formed in 1999 by a group of [[Massachusetts Institute of Technology]] students with the aim to develop a secure, decentralized system of data storage.<ref name="freehaven">{{cite web | url=http://freehaven.net/ | title=Free Haven | publisher=Free Haven Project | work=Freehaven.net | access-date=4 June 2014 | archive-date=19 June 2014 | archive-url=https://web.archive.org/web/20140619104543/http://www.freehaven.net/ | url-status=live }}</ref> The group's work led to a collaboration with the [[United States Naval Research Laboratory]] to develop [[Tor (anonymity network)|Tor]], funded by [[DARPA]].<ref name="ieee">{{cite journal | url=http://apps.dtic.mil/dtic/tr/fulltext/u2/a527761.pdf | title=Deploying Low-Latency Anonymity: Design Challenges and Social Factors | last1=Dingledine | first1=R. | last2=Mathewson | first2=N. | last3=Syverson | first3=P. | journal=IEEE Security & Privacy | year=2007 | volume=5 | issue=5 | pages=83–87 | doi=10.1109/MSP.2007.108 | s2cid=11387129 | access-date=2022-01-04 | archive-date=2014-06-06 | archive-url=https://web.archive.org/web/20140606220222/http://www.dtic.mil/dtic/tr/fulltext/u2/a527761.pdf | url-status=live }}</ref><ref name="net working">{{cite book | title=Net Working/Networking: Citizen Initiated Internet Politics | chapter-url=https://books.google.com/books?id=29Ucv7BU_DYC&pg=PA267 | publisher=University of Tampere | editor1-first=Tapio | editor1-last=Häyhtiö | editor2-last=Rinne | editor2-first=Jarmo | last=Jordan | first=Tim | chapter=The Politics of Technology: Three Types of 'Hacktivism' | year=2008 | pages=267 | isbn=9789514474644 | access-date=2022-01-04 | archive-date=2015-03-19 | archive-url=https://web.archive.org/web/20150319070238/http://books.google.com/books?id=29Ucv7BU_DYC&pg=PA267 | url-status=live }}</ref>

==Distributed anonymous storage system==

The Project's early work focused on an anonymous storage system, Free Haven, which was designed to ensure the privacy and security of both readers and publishers.<ref name="hansen">{{cite conference | last=Hansen | first=J.

Free Haven is a distributed peer-to-peer system designed to create a "servnet" consisting of "servnet nodes" which each hold fragments ("shares") of documents, divided using Rabin's Information dispersal 
algorithm such that the publisher or file contents cannot be determined by any one piece.<ref name="pet">{{cite conference | url=http://www.cs.princeton.edu/~mfreed/docs/freehaven-pet00.pdf | title=The Free Haven Project: Distributed Anonymous Storage Service | publisher=Springer-Verlag | access-date=2 June 2014 | author1=Dingledine, R. | author2=Freedman, M.

==Work with Tor==
{{main article|Tor (anonymity network)}}
Tor was developed by the US Naval Research Laboratory and the Free Haven Project to secure government communications, with initial funding from the US [[Office of Naval Research]] and DARPA. Tor was deployed in 2003, as their third generation of deployed [[onion routing]] designs.<ref name="ieee"/> In 2005, the [[Electronic Frontier Foundation]] provided additional funding to the Free Haven Project.<ref name="ieee"/> In 2006, the Tor Project was incorporated as a non-profit organization.<ref name="ieee"/>
