Data mining
Data mining uses statistical models, algorithms, and cluster analysis to transform information such as credit card purchases, travel history, and internet activity into electronically processed data with the aim of targeting suspects and profiling risks more precisely. Increasingly relied upon by both the public and private sectors, it has also become a tool of counterterrorism, and more specifically of predictive intelligence. In this regard, data mining enables Homeland Security officials to identify factors that are likely to indicate great risk, such as whether the person belongs to an extremist group or has ever bought explosives. By assigning these factors a higher weight than slightly less relevant factors such as the individual-in-questions travel patterns, or internet activity, a formula can be calculated to predict whether the person is likely to be a terrorist. Data mining, in essence, is a predictive analysis technique that helps authorities deal with uncertainty.
