1. In a verification system including a processing device, the verification system having items intended for a single use, in which usage of an item is confirmed by scanning an identification number associated with the item, and wherein scanning activity is inconsistent, a method for identifying a suspect for fraudulent use of the identification numbers comprising: creating, by the processing device, a profile of scanning activity for a plurality of items that meet a first parameter, the profile including a percentage of items that meet the first parameter that have been scanned more than once; creating, by the processing device, a profile of scanning activity for a plurality of items used by a specified user, the profile including a total number of scans for items used by the specified user that meet the first parameter and a percentage of items used by the specified user that meet the first parameter that have been scanned more than once; analyzing, by the processing device, the profile of scanning activity for the plurality of items used by the specified user to determine that the total number of scans for items used by the specified user that meet the first parameter exceeds a predetermined minimum number and that the percentage of items used by the specified user that meet the first parameter that have been scanned more than once is greater than a first threshold value, the first threshold value being based on the percentage of items that meet the first parameter that have been scanned more than once from the profile of scanning activity for the plurality of items that meet the first parameter; and identifying, by the processing device, the specified user as a suspect for fraudulent use of the identification numbers.
