1. A method, in a data processing system, for security screening image analysis simplification through object pattern identification, the method comprising: scanning an object to form an electronic representation of the scanned object; generating an electronic signature of the scanned object; reducing the electronic signature to a hash value for the scanned object; comparing the hash value for the scanned object against a set of hash values for known safe objects; responsive to the hash value for the scanned object not matching a hash value for a known safe object, determining whether the scanned object is similar to a previously scanned object; responsive to the scanned object being similar to a previously scanned object, incrementing a counter associated with the previously scanned object; and responsive to the counter associated with the previously scanned object reaching a pedetermined threshold, adding the hash value for the scanned object to the set of hash values for known safe objects.
