A first portion is extracted from the first electronic submission and a second portion is extracted from the second electronic submission. A first code is determined for the first portion and a second code is determined for the second portion. The first code is indicative of the first portion and the second code is indicative of the second portion. After the first code is compared to the second code, the second electronic submission is filtered in response to that comparison.
