When the US Congress curtailed Pentagon research it feared would ensnare innocent Americans in the terrorism fight, it also allowed the Bush administration to eliminate two projects to protect citizens' privacy from futuristic tools.
As a result, the government is quietly pressing ahead with research into high-powered computer data-mining technology without the two most advanced privacy protections developed for those terror-fighting tools.
"It's very inconsistent what they've done," said Teresa Lunt of the Palo Alto Research Center and head of one of the two government-funded privacy projects eliminated last fall.
Even members of Congress such as Senator Ron Wyden, who led the fight to restrict the Pentagon terrorism research over its privacy implications, remain uncertain about the nature of the research or the safeguards.
"We feel Congress is not getting enough information about who is undertaking this research and where it's headed and how they intend to protect the civil liberties of Americans," said Chris Fitzgerald, Wyden's spokesman.
The privacy projects were small parts of the Pentagon's Terrorism Information Awareness research.
The project was the brainchild of retired Admiral John Poindexter, who was driven from the Reagan administration in 1986 over the Iran-Contra scandal. Some 15 years later, he was summoned back by the Bush administration to develop data-mining tools for the fight against terrorism.
Poindexter's new software tools, far more powerful than existing commercial products, would have allowed government agents to quickly scan the private commercial transactions and personal health records of millions of Americans and foreigners for telltale signs of terrorist activity.
Partly to appease critics, Poindexter also was developing two tools that would have concealed names on records during the scans. Only if agents discovered concrete evidence of terrorist activities would they have been permitted to learn the identities of the people whose records aroused suspicion.
One privacy project worked with Poindexter's Genisys program, which scanned government and commercial records for terrorist planning. The other was part of his Bio-ALIRT program, which scanned private health records for evidence of biological attacks.
Late last year, Congress closed Poindexter's office in the Defense Advanced Research Projects Agency (DARPA) in response to the uproar over its impact on privacy.
But Congress allowed some Poindexter projects, including some data-mining research, to be transferred to intelligence agencies. Congress also left intact similar data-mining research begun in the fall of 2002 by the Advanced Research and Development Activity (ARDA), a little-known office that works on behalf of US intelligence.
The research sponsored by ARDA, called Novel Intelligence from Massive Data, is so similar to some work done for Poindexter that Lunt offered to adapt her privacy protection software. ARDA was uninterested.
"When I went to talk to them, ARDA made clear they don't want to get into any area Congress doesn't want to fund," Lunt said.
It's not clear what, if any, privacy research is being done by ARDA or by the surviving remnants of Poindexter's program.
Last fall's Intelligence Authorization Act approved continued research on the type of powerful data mining Poindexter envisioned but said "the policies and procedures necessary to safeguard individual liberties and privacy should occur concurrently with the development of these analytic tools, not as an afterthought."
