DIGITAL FINGERPRINTING OBJECT AUTHENTICATION AND ANTI-COUNTERFEITING SYSTEM

摘要

Improvements are disclosed for authentication of an object, verification of its provenance, and certification of the object as compliant with manufacturing standards. Or, an object may be reported as a suspected counterfeit. In one embodiment the system compares a digital fingerprint of the object, based in image capture, to digital fingerprints previously stored in a database and determines if the object has been registered before and is thus authentic. An object feature template may be created which has a list of features and attributes that are relevant for authenticating particular classes of objects. The object feature template can also be used to examine unregistered objects for signs of counterfeiting.

主权项

1. A computer implemented method comprising:
acquiring digital image data representing an image of at least a portion of a physical object; selecting at least one authentication region of the image data; processing the authentication region data so as to form a digital fingerprint of the object, wherein the digital fingerprint comprises:
data identifying at least one object feature within the authentication region, the data including a location of the object feature in the authentication region;for each object feature, data identifying a plurality of locations of interest in the object feature; andfor each locations of interest, data identifying at least one fingerprint feature vector that describes a fingerprint feature extracted from the location of interest; and storing the digital fingerprint of the object in an object database.
