Abstract:
1. A system for detecting duplicate checks, comprising: at least one processor; a memory comprising computer-readable instructions which when executed by the processor cause the processor to perform the steps comprising: receiving check data that comprises check accounting data associated with one or more checks; processing the check data to extract the check accounting data; creating a character string from a subset of the check accounting data for each of the one or more checks; applying a Bloom filter using four hash functions to the character string such that four single bit hash value addresses are computed; determining that a check is a potential suspected duplicate the four bits values addressed by the four single bit hash value addresses being equal to a first value; outputting a listing of each potential suspected duplicate; and performing additional processing on each potential suspected duplicate to determine if the potential suspected duplicate is a true suspected duplicate.
