The Federal Bureau of Investigation is developing a computer-profiling system that would enable investigators to target possible terror suspects. The System to Assess Risk, or STAR, assigns risk scores to possible suspects based on a variety of information, similar to the way a credit bureau assigns a rating based on a consumer's spending behavior and debt. The program focuses on foreign suspects but also includes data about some U.S. residents. Some lawmakers said ... that the report raises new questions about the government's power to use personal information and intelligence without accountability. The Bush administration has expanded the use of this technology, often in secret, to collect and sift through Americans' most sensitive personal information," said Sen. Patrick J. Leahy (D-Vt.), chairman of the Senate Judiciary Committee. The use of data mining in the war on terror has sparked criticism. An airplane-passenger screening program called CAPPS II was revamped and renamed because of civil liberty concerns. An effort to collect Americans' personal and financial data called Total Information Awareness was killed. Law enforcement and national security officials have continued working on other programs to use computers to sift through information for signs of threats. The Department of Homeland Security, for example, flags travelers entering and leaving the United States who may be potential suspects through a risk-assessment program called the Automated Targeting System.
