Collage: Defeating Censorship with User-Generated Content

E-mail Print PDF

Collage is a new censorship-resistant publication system based around the recent prevalence of user-generated Web content. It provides a coniable covert publication channel for transmitting sensitive information to Web users in regions with restricted Internet access.

Most users interact with Collage using client software. Currently under active development, this client takes the form of a Firefox extension. Using this software, users can subscribe to and download content published on multiple popular Web content hosts.

A preview version of this software was demonstrated at the NSDI 2009 demo session. You can download this version here. To install it, extract the tarball and read the README file.

NEW!

We have released a test version of the Collage photo donation tool. It allows Flickr users to donate your photos for use with Collage. Download it and take it for a spin.
