Abstract
Improvements are disclosed for detecting counterfeit objects, based on comparison to digital fingerprints that describe features found in images of objects known to be counterfeit.
Claims12
A computer-implemented method comprising:
- acquiring digital fingerprints of a plurality of known counterfeit objects of a given class;
- and
- storing the digital fingerprints in a datastore to form a machine-readable counterfeit object database for use in detecting counterfeit objects of the given class.
An apparatus comprising:
- an image capture device arranged to generate image data responsive to a surface region of a physical object;
- a processor having electronic access to the image data;
- the processor arranged to execute stored instructions for processing the image data, the stored instructions arranged to cause the processor to—
- access a predetermined object feature template associated with a class of objects of which the physical object is a member;
- wherein the object feature template specifies an authentication region, at least one object feature within the authentication region, a method for extracting a fingerprint feature from the object feature, and a method for comparing the extracted feature to a reference feature;
- based on the object feature template, identify a subset of the image data corresponding to the authentication region;
- based on the object feature template, extract a feature from the subset of the image data;
- and
- store extracted feature data defining the extracted feature in an object database record.
