Abstract: A fraud management system is configured to store rules for detecting fraud. The fraud management system is further configured to receive a transaction involving a consumer and a merchant; obtain network security information associated with malicious activity in a voice network or a data network, where the network security information indicates that the consumer has been involved in malicious activity in the voice network or in the data network; select a subset of rules based on the network security information and information associated with the transaction, the merchant, or the consumer; process the transaction using the subset of rules to generate alarms; process the alarms to generate a fraud score for the transaction; and output information regarding the fraud score to the merchant to assist the merchant in determining whether to accept, deny, or fulfill the transaction.

Abstract: A fraud management system is configured to store rules for detecting fraud, receive a transaction from a merchant, process the transaction using a first subset of rules to generate a fraud score for the transaction, and output information regarding the fraud score to the merchant to assist the merchant in determining whether to accept, deny, or fulfill the transaction. The fraud management system is further configured to receive, after outputting the information regarding the fraud score to the merchant, additional information relating to the transaction, re-process the transaction using a second subset of rules to generate an update fraud score, and output information regarding the updated fraud score to the merchant to assist the merchant in determining whether to accept, deny, or fulfill the transaction.

Abstract: A fraud management system is configured to store rules for detecting fraud. The fraud management system is configured to: receive a transaction involving a consumer and a merchant; select a set of the rules based on information associated with the transaction, information associated with the consumer, or information associated with the merchant; process the transaction, in parallel, using the selected rules to generate a set of alarms; group the alarms, into groups, based on information associated with the transaction; analyze the groups to generate a fraud score; and output information regarding the fraud score to the merchant to notify the merchant whether the transaction is potentially fraudulent.

Abstract: A fraud management system is configured to receive a transaction from a merchant; select rules to use to process the transaction; process the transaction using the selected rules to generate a set of alarms; and generate an alarm score for each of the alarms. The fraud management system is further configured to combine the alarms with alarms from one or more other transactions to form a combined set of alarms; sorting alarms, in the combined set of alarms, into groups based on attributes of the transaction; generate a group score, for each group, based on at least one of the alarm scores for at least one alarm in the group; generate a fraud score, for the transaction, based on one or more of the group scores; and output information regarding the fraud score to the merchant to notify the merchant whether the transaction is potentially fraudulent.
