Abstract: Financial transactions in a centralized clearing system generate substantial data, which presents challenges to finding useful information about those transactions. From a transaction data set, trajectories are defined, each of the trajectories having a source and a destination and indicating a flow of a given resource through at least one via point based on a plurality of transactions of the transaction data set. The given resource can be a function of the transferred amounts of the plurality of transactions. A map relating the trajectories based on common sources and destinations is generated, and a network analysis is then applied to the map to produce analytics of the transactions. From the analytics, useful information about the transactions, such as instances of potential fraud, can be reported.
