Data Mining: An Overview
Summary
Data mining is emerging as one of the key features of many homeland security
initiatives. Often used as a means for detecting fraud, assessing risk, and product
retailing, data mining involves the use of data analysis tools to discover previously
unknown, valid patterns and relationships in large data sets. In the context of
homeland security, data mining is often viewed as a potential means to identify
terrorist activities, such as money transfers and communications, and to identify and
track individual terrorists themselves, such as through travel and immigration
records.
