Collecting the online profile data will allow for greater accuracy for the Real-time detection. EFD phase has much impact on the Sign On, Bill Pay and Funds Transfer transactions. Cyota and Iovation are the two risk decisioning systems to identify the risks associated with the transactions. Transaction details are sent from the mobile service management layer MSM to these risk decisioning systems for risk scoring before EFD phase. As part of the EFD phase we have moved these decision systems beyond the TIBCO layer. As a result, transaction details are first sent to the TIBCO layer and then to the Cyota Iovation systems. TIBCO is introduced as an interface to communicate with several back end systems. Synchronous and Asynchronous calls are made to the back-end systems in various scenarios for accept and reject transactions.
