Patent ID: 8666861

Claim:
A method, comprising: processing, by at least one computing device, a plurality of transactions without applying one or more active fraud rules, wherein each transaction of the plurality of transactions is selected from a larger plurality of received transactions by the at least one computing device executing a random selection algorithm for inclusion in the plurality of transactions to be processed without application of the one or more active fraud rules; allowing the plurality of transactions to be authorized when the one or more active fraud rules indicate one or more of the transactions as fraudulent; determining, by the at least one computing device, based on the plurality of transactions a hit rate for at least one fraud rule of the one or more active fraud rules, wherein the hit rate represents a first set of transactions of the plurality of transactions that would be declined by operation of the at least one fraud rule if the at least one fraud rule had been applied during the processing; determining, by the at least one computing device, based on fraud event data corresponding to the plurality of transactions, a positive hit rate for the at least one fraud rule; wherein the positive hit rate represents a second set of transactions corresponding to one or more transactions of the first set that resulted in at least one fraud event; deactivating, by the at least one computing device, the at least one fraud rule in response to determining that a ratio of the positive hit rate to the hit rate is less than a predetermined threshold amount; and allowing subsequent transactions to be authorized without applying the deactivated at least one fraud rule.
