Abstract
A method of verifying an identity of a printed item includes capturing an image of the unverified printed item, wherein the unverified printed item includes artifacts and at least some of the artifacts were not controllably producible in producing the unverified printed item; extracting information associated with the artifacts of the unverified printed item; ranking the information associated with the artifacts of the unverified printed item; retrieving stored ranked information associated with artifacts of an original printed item from a storage device; and in each of a first and second range of magnitudes, comparing the ranked information associated with the artifacts of the unverified printed item with the ranked information associated with the artifacts of the original printed item.
