Automated fraud management in transaction-based networks
First Claim
1. A computer-implemented method for managing fraud in a telecommunications network, comprising the step of:
- automatically generating one or more recommendations for responding to suspected fraudulent activity in the telecommunications network, wherein the recommendations are derived as a function of calls scored for the likelihood of fraud, and wherein the recommendations correspond to attributes of the suspected fraudulent activity so that a recommended response to the suspected fraudulent activity is targeted to the type of fraud that is occurring.

Abstract
Fraud losses in a communication network are substantially reduced by automatically generating fraud management recommendations in response to suspected fraud and by deriving the recommendations as a function of selected attributes of the fraudulent activity. More specifically, a programmable rules engine automatically generates recommendations based on call-by-call fraud scoring so that the recommendations correspond directly to the type and amount of suspected fraudulent activity. Using telecommunications fraud as an example, an automated fraud management system receives call detail records that have been previously scored to identify potentially fraudulent calls. Fraud scoring estimates the probability of fraud for each call based on the learned behavior of an individual subscriber as well as that of fraud perpetrators. Scoring also provides an indication of the contribution of various elements of the call detail record to the fraud score for that call. A case analysis is initiated and previously scored call detail records are separated into innocuous and suspicious groups based on fraud scores. Each group is then characterized according to selected variables and scoring for its member calls. These characterizations are combined with subscriber information to generate a set of decision variables. A set of rules is then applied to determine if the current set of decision variables meets definable conditions. When a condition is met, prevention measures associated with that condition are recommended for the account. As one example, recommended prevention measures may be automatically implemented via provisioning functions in the telecommunications network.

26. A system for managing fraud in a network where transactions occur, comprising:
-
means for deriving one or more recommendations for responding to suspected fraudulent activity in the network as a function of transactions scored for the likelihood of fraud; and means for automatically generating the one or more recommendations, wherein the recommendations correspond to selected attributes of the suspected fraudulent activity so that a recommended response to the suspected fraudulent activity is targeted to the type of fraud that is occurring.

27. A system for managing fraud in a telecommunications network, comprising:
-
at least one memory device for receiving, storing, and supplying call detail records that have been scored to identify potentially fraudulent activity, wherein a scored call detail record provides an indication of the contribution to the fraud score of a plurality of predetermined call variables; and a computer processor, coupled to the at least one memory device, for executing programmed instructions to automatically generate one or more recommendations for responding to suspected fraudulent activity in the telecommunications network, wherein the recommendations are derived as a function of the scored call detail records, and wherein the recommendations correspond to selected attributes of the suspected fraudulent activity so that a recommended response to the suspected fraudulent activity is targeted to the type of fraud that is occurring.

28. A system for managing fraud in a telecommunication network, comprising:
-
a call scoring element responsive to call detail records generated within the network for scoring a call to determine the likelihood of fraud; and a case analysis element responsive to scored call detail records and subscriber account information for analyzing a case of suspected fraud and for automatically generating recommendations for responding to the suspected fraud, wherein recommended fraud responses correspond to attributes of the suspected fraud so that management of the suspected fraud is targeted to the type of fraud that is occurring. - View Dependent Claims (29, 30, 31)
