Abstract:
1. A computer-implemented method for detecting duplicate checks, the method comprising the steps of: receiving check data wherein the check data comprises at least check accounting data associated with one or more checks; applying, by a computer processor, a function to the check data wherein the function computes a value based on the check data and the value is one of a set of elements; selecting, by the computer processor, an element from the set where an index of the element corresponds to the computed value and the index is an index to a set of Boolean objects, the steps of applying and selecting further comprising: determining that a check is not a duplicate if the element is in an initialized state, the step of determining that the check is not a duplicate further comprising: determining that the check is a suspected duplicate if the element is in an altered state, and modifying the element by altering a state of the element, the step of modifying further comprising: setting the state of the addressed bit in the hash table to the altered state if the address of the single hit is not equal to the altered state.
