Systems and methods for enhanced fraud detection based on transactions at potentially compromised locations

Abstract:

A computer-implemented method for enhancing fraud detection based on transactions at potentially compromised locations is provided. The method includes determining a list of potentially compromised transaction locations, storing the list of potentially compromised transaction locations, and receiving from a first transaction location a first authorization request message for a first transaction. The first authorization request message is associated with a first payment account. The method also includes determining the first transaction location based on the first authorization request message, determining if the first transaction location is in the list of potentially compromised transaction locations, and if the determination is that the first transaction location is included in the list of potentially compromised transaction locations, flagging the first payment account as potentially compromised so that a fraud score for a future transaction is associated with the first payment account is adjusted based on the potentially compromised flag.
