FAST ACCESS VECTORS IN REAL-TIME BEHAVIORAL PROFILING IN FRAUDULENT FINANCIAL TRANSACTIONS

A computer-implemented method for real-time transaction fraud vetting, including: receiving a transaction record including real-time transaction data and a key identifying a transacting entity; matching the key to a plurality of profiles of the transacting entity, each of the plurality of profiles including a data attribute; accessing a datapoint for each of the plurality of profiles, each datapoint representing a standard for the corresponding data attribute computed from historical transaction records of the transacting entity; assessing whether deviation of the real-time transaction data from each datapoint exceeds a corresponding threshold; incrementing a transaction risk corresponding to the transaction record for each deviation from one of the datapoints that exceeds the corresponding threshold; outputting a fraud score based at least in part on the transaction risk; and updating at least one datapoint based on the corresponding real-time transaction data to generate an updated datapoint set for the plurality of profiles.
