The government's top intelligence agency is building a computerized system to search very large stores of information for patterns of activity that look like terrorist planning. The system, which is run by the Office of the Director of National Intelligence, is in the early research phases and is being tested, in part, with government intelligence that may contain information on U.S. citizens and other people inside the country.
It encompasses existing profiling and detection systems, including those that create "suspicion scores" for suspected terrorists by analyzing very large databases of government intelligence, as well as records of individuals' private communications, financial transactions, and other everyday activities.
The details of the program, called Tangram, are contained in an unclassified document that National Journal obtained from a government contracting Web site. The document, called a "proposer's information packet," is a technical description of Tangram written for potential contractors who would help design and test the system. The document was written by officials in the research-and-development section of the national intelligence office. A tangram is an old Chinese puzzle that takes seven geometric shapes -- five triangles, a square, and a parallelogram -- and rearranges them into different pictures.
