Information fusion is
|“||the process of managing the flow of information and intelligence across all levels and sectors of government and private industry, and through analysis, creating meaningful intelligence products.||”|
|“||the acquisition of data from many sources, the integration of these data into usable and accessible forms, and their interpretation.||”|
"Such integrated data can be particularly valuable for decision makers in law enforcement, the intelligence community, emergency-response units, and other organizations combating terrorism. Information fusion gains power and relevance for the counterterrorist mission because computer technology enables large volumes of information to be processed in short times."
