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.
Claims13
A method, comprising:
- acquiring a first image of a first physical object;
- extracting first image data from the first image that describes one or more optically discernible features of the first physical object;
- generating a first digital fingerprint of the first physical object that uniquely identifies the first physical object based on the extracted first image data wherein the first digital fingerprint includes a first piece of data identifying a plurality of locations of interest of the first physical object and, for each location of interest, a second piece of data forming at least one fingerprint feature vector that describes a fingerprint feature extracted from the location of interest;
- storing the first digital fingerprint in a database, wherein the database stores a plurality of digital fingerprints associated with a plurality of physical objects;
- acquiring a second image of a second physical object;
- extracting second image data from the second image that describes one or more optically discernible features of the second physical object;
- generating a second digital fingerprint of the second physical object based on the extracted second image data;
- comparing the second digital fingerprint with the first digital fingerprint and at least one of the plurality of digital fingerprints in the database to obtain a result;
- and
- executing a predetermined action based on the result.
7 more elements
A non-transitory computer-readable storage medium whose stored contents configure a computing system to perform a method, the method comprising:
- acquiring a first image, the first image being an image at least a portion of a first physical object;
- isolating image data associated with a first portion of the first physical object;
- creating a first digital fingerprint of the first physical object based on indicia interpreted in the image data, wherein the first digital fingerprint includes a first piece of data identifying a plurality of locations of interest of the first physical object and, for each location of interest, a second piece of data forming at least one fingerprint feature vector that describes a fingerprint feature extracted from the location of interest;
- and
- storing the first digital fingerprint in a database, the database having stored therein a plurality of digital fingerprints associated with a plurality of physical objects, wherein the first digital fingerprint identifies the first physical object as being unique among the plurality of objects.
