Following up on our earlier post regarding the Era of Hashtag Surveillance, the FBI has published documents indicating that it intends to enter into a deal with a Twitter data miner, appropriately named Dataminr (and partially owned by Twitter), for access to its monitoring technology. Techcrunch reports that the FBI disclosed its intent to enter into a licensing agreement with Dataminr for access to Twitter’s “firehose” data stream. As opposed to the normal data streams that Twitter makes available to the public which only provide access to a fraction of the posts made to the site, the “firehose” stream contains all public posts made on Twitter and would essentially allow a user to search, in almost real-time, every post made to the service.
