HIGH RESOLUTION TRANSACTION-LEVEL FRAUD DETECTION FOR PAYMENT CARDS IN A POTENTIAL STATE OF FRAUD

摘要

A system and method are disclosed, to distinguish fraudulent transactions from a legitimate transaction, predicated on the notion that the card is considered likely to be in state of fraud. The disclosed system and method can be activated as soon as an account has suspicious activity that causes a high score for potential fraud, but before a bank either can or needs to confirm fraud. The system or method is able to pinpoint the actual fraudulent transactions inside a window of potential fraudulent activity, using a specialized model referred to as the pinpoint model.
