Starlight has already helped foil some terror plots, says Jim Thomas, one of its developers and director of the government's new National Visualization Analytics Center in Richland, Wash. He can't elaborate because the cases are classified, he adds. But "there's no question that the technology we've invented here at the lab has been used to protect our freedoms - and that's pretty cool."
As envisioned, ADVISE and its analytical tools would be used by other agencies to look for terrorists. "All federal, state, local and private-sector security entities will be able to share and collaborate in real time with distributed data warehouses that will provide full support for analysis and action" for the ADVISE system, says the 2004 workshop report.
Yet the scope of ADVISE - its stage of development, cost, and most other details - is so obscure that critics say it poses a major privacy challenge.
"We just don't know enough about this technology, how it works, or what it is used for," says Marcia Hofmann of the Electronic Privacy Information Center in Washington. "It matters to a lot of people that these programs and software exist. We don't really know to what extent the government is mining personal data."
Even congressmen with direct oversight of DHS, who favor data mining, say they don't know enough about the program.
"I am not fully briefed on ADVISE," wrote Rep. Curt Weldon (R) of Pennsylvania, vice chairman of the House Homeland Security Committee, in an e-mail. "I'll get briefed this week."
