Abstract:
1. A method for transaction counting in a fraud detection system, the method comprising: storing in a memory of a computer, a plurality of initial-buckets associated with a first time interval and a plurality of roll-up buckets associated with a second time inter-val, wherein the first time interval is contained within the second time interval; at the computer, receiving a transaction from a network, the transaction including a transaction timestamp; formatting the transaction timestamp to generate a formatted transaction time-stamp; based on said transaction timestamp, determining a particular initial-bucket of said plurality of initial-buckets in which to store the transaction; wherein said particular initial-bucket is associated with a sub-time interval of said first time interval; wherein said particular initial-bucket has a bucket count that indicates a number of one or more previously received transactions that occurred during said sub-time interval of said first time interval; in response to the computer determining that a time indicated by said transaction timestamp is not within said sub-time interval of said first time interval, the computer adding the bucket count for the particular initial-bucket to a bucket count of a particular roll-up bucket; and storing the transaction in the particular initial-bucket in the memory of the computer.
