METHODS AND A COMPUTING DEVICE FOR DETERMINING WHETHER A MARK IS GENUINE

摘要

The present disclosure is generally directed to a method and computing device for determining whether a mark is genuine. According to various embodiments, a computing device (or logic circuitry thereof) uses unintentionally-produced artifacts within a genuine mark to define an identifiable electronic signature, and extracts certain location identifiers corresponding to certain measured features of the signature in order to enhance the ease and speed with which numerous genuine signatures can be searched and compared with signatures of candidate marks.

主权项

1. On a computing device, a method for determining whether a mark is genuine, the method comprising:
receiving a captured image of a candidate mark; measuring, using the captured image, a characteristic of the candidate mark at a plurality of locations within the candidate mark, resulting in a set of metrics for the characteristic, wherein the plurality of locations is associated with a plurality of location identifiers; generating, based on the set of metrics, an electronic signature for the candidate mark; deriving a hash identifier for the candidate mark using a subset of the plurality of location identifiers; determining, based on a comparison of the hash identifier of the candidate mark with a hash identifier of a genuine mark, whether the hash identifier of the candidate mark closely matches the hash identifier of the genuine mark; if the hash identifier of the candidate mark is determined to closely match the hash identifier of the genuine mark, then
retrieving, from a media storage device, an electronic signature of the genuine mark, wherein the electronic signature of the genuine mark contains data regarding an artifact of the genuine mark; anddetermining, based on a comparison of the electronic signature of the candidate mark with the retrieved electronic signature of the genuine mark, whether the candidate mark is genuine;if the candidate mark is determined to be genuine, then indicating that the candidate mark is genuine.
