Add Capability to efficiently interface with external fraud monitoring system

[edcable]

DFSP could implement a separate fraud monitoring system which could be invoked by the Payment Hub as part of the outgoing or incoming payment flow. DFSP side fraud monitoring could utilize much more information about the customer, compared to simply monitoring the flow of transactions, such as: A priori knowledge of customer’s accounts, typical transaction mix, channels, geolocations, devices used, rate of typing. Transactions can be:

• Stopped - in case of scoring high by the fraud monitoring system
• Paused - contacting the customer for validation on other channel and resume the transaction later
• Let it go through
• Fraud monitoring does not alert on the given transaction
• Fraud monitoring subsystem is not responding in the given timeframe
