Abstract
Embodiments of the invention are directed to a fraud detection system that automatically converts the currency and value of received transaction data to correspond to the currency in fraud detection rules established by a merchant. The converted transaction data is then analyzed against the fraud detection rules to determine whether the transaction data indicates fraudulent activity.
Claims20
A method comprising:
- providing, by a server computer, a user interface on a client computer for viewing and modifying a plurality of fraud detection rules for detecting fraudulent transactions;
- receiving, by the server computer, a first value in a first currency via the user interface on the client computer operated by a user;
- generating, by the server computer, a fraud detection rule using the received first value in the first currency;
- storing, by the server computer, the fraud detection rule and the first currency in a merchant profile;
- subsequent to storing the fraud detection rule, receiving, by the server computer, transaction data including a transaction total and a currency indicator;
- determining, by the server computer, that the currency indicator corresponds to a second currency that is different from the first currency stored in the merchant profile;
- obtaining, by the server computer, an exchange rate between the first currency and the second currency;
- automatically determining, by the server computer, a converted transaction total in the first currency using the exchange rate;
- evaluating, by the server computer, the converted transaction total in the first currency using the first value from the fraud detection rule;
- and
- providing, by the server computer, a message based on the evaluation of the converted transaction total in the first currency using the first value from the fraud detection rule.
