A small fun project and a paraphrase of "Plasm: not a crime". https://vimeo.com/11793767
A proof of concept implementation of Chaffing and winnowing technique in twitter. (with bots) The Sender types the message. A hash of the message gets tweeted by public hash bot. The original message gets split and tweeted together with a twitter hashtag, which works as a kind of key, by a variable number of bots. The receiver scrapes the hash from the hashbot and opens a stream of the hashtag. It then calculate live hashes of every message in the stream and can filter the message out of the stream.
Needs at minimum 3 Twitter api keys to work basic. Might get stem in next version.
