  • Publication number: 20210166238
    Abstract: While mobile device location remains, private, user transaction controls are applied to a specific authorization request. The user transaction controls are pre-configured by the user of the mobile account holder device and identified by the enriched merchant data. Location algorithms predict transaction locations used to obtain enriched merchant data responsive to location privacy mode. Responsive to the user transaction controls, a fraud recommendation response is sent to the approval system, in real time with the transaction. The fraud recommendation response prevents a false negative by using an enriched merchant location rather than the raw merchant location.

  • Publication number: 20210166237
    Abstract: Raw merchant data of real-time ISO transactions is enriched with normalized merchant data, including a normalized merchant name, a normalized merchant location, by transmitting the raw merchant data to an external resource and receiving the normalized raw merchant data from the external resource. An authorization request from a real-time ISO transaction concerning a specific mobile user can be initiated by a specific merchant device at a merchant location. A user location is obtained and utilized to identify enriched merchant data. It is the enriched merchant data that is used for deciding whether to approve or deny a transaction with more accuracy.
