The new system will use "dynamic intelligence information" to select passengers for extra screening. Under CAPPS II, the number of airplane travelers going through extra screening is expected to drop significantly from the 15 percent that undergo it today, Loy told lawmakers. Addressing one concern of the privacy rights community, Loy testified that CAPPS II will not store large quantities of data or retain data on passengers that are cleared to board planes. After travel is completed, the records will be purged, he said.
Loy also testified that the systems authentication function will be conducted mostly by non-government databases with commercially available data, and the employees of the data companies will not directly view the passengers personal information.
DARPA is pursuing a somewhat different kind of data mining, according to Anthony Tether, DARPA director. Recognizing that identifying complicated terrorist plots requires detecting extremely rate patterns, the Pentagons research agency is developing technology to search for evidence of specified patterns, Tether said in written testimony to the subcommittee. DARPAs new method begins with the development of terrorism scenarios based on previous attacks, intelligence analysis, "war games in which clever people imagine ways to attack the United States and its deployed forces," and other information, Tether said in his testimony Tuesday. Then data would be queried using "either known, identified suspects or known, identified patterns," he said. Subcommitte Chairman Adam Putnam, R- Fla., said the subcommittee panel will meet in two weeks to take a look at the privacy and personal freedom questions raised by data mining.
