FBI data warehouse revealed by EFF

May 14, 2009

Tenacious FoI and ‘institutional discovery’ work both in and out of the US courts by the Electronic Frontier Foundation has resulted in the FBI releasing lots of information about its enormous dataveillance program, based around the Investigative Data Warehouse (IDW). 

The clear and comprehensible report is available from EFF here, but the basic messages are that:

  •  the FBI now has a data warehouse with over a billion unique documents or seven times as many as are contained in the Library of Congress;
  • it is using content management and datamining software to connect, cross-reference and analyse data from over fifty previously separate datasets included in the warehouse. These include, by the way, both the entire US-VISIT database, the No-Fly list and other controversial post-9/11 systems.
  • The IDW will be used for both link and pattern analysis using technology connected to the Foreign Terrorist Tracking Task Force (FTTTF) prgram, in other words Knowledge Disovery in Databases (KDD) software, which will through connecting people, groups and places, will generate entirely ‘new’ data and project links forward in time as predictions.

EFF conclude that datamining is the future for the IDW. This is true, but I would also say that it was the past and is the present too. Datamining is not new for the US intelligence services, indeed many of the techniques we now call datamining were developed by the National Security Agency (NSA). There would be no point in the FBI just warehousing vast numbers of documents without techniques for analysing and connecting them. KDD may well be more recent for the FBI and this phildickian ‘pre-crime’ is most certainly the future in more ways than one…

There is a lot that interests me here (and indeed, I am currently trying to write a piece about the socio-techncial history of these massive intelligence data analysis systems), but one issue is whether this complex operation will ‘work’ or whether it will throw up so many random and worthless ‘connections’ (the ‘six-degrees of Kevin Bacon’ syndrome) that it will actually slow-down or damage actual investigations into real criminal activities. That all depends on the architecture of the system, and that is something we know little about, although there are a few hints in the EFF report…
