Telephone fraud costs U.S. businesses billions of dollars a year. To combat fraud, AT&T Labs developed a suite of state-of-the-art fraud protection tools offered to phone companies that rely on the AT&T Network Connection (ANC) system for transport of long-distance services. The ANC fraud protection package made it possible to detect fraud in a matter of hours rather than days.
The foundation of the ANC fraud protection package is signature profiling technology ? a service only offered by AT&T. Signature profiling takes the specific code assigned to an ANC user ? the signature ? and monitors network usage by that signature in order to establish the signature profile. Since deviations from the profile can indicate instances of fraud, the customer is alerted to anomalies.
Other AT&T Labs-developed technology supporting the ANC fraud protection package include SCAMPweb, data visualization, and the Fraud Call Records Service. SCAMPweb is a query tool that lets users retrieve statistics on call details sorted by such criteria as time of call, length of call, recipient of call, etc. The data visualization feature is a color-coded, graphic display of call details, making anomalies easier to identify. The Fraud Call Records Service is a feed of call detail data to a customer's own system, where customers can apply their own logic and thresholds for detecting fraud.
