System and Method for Document and Article Authentication

摘要

A system for authentication of paper sheet and other articles includes an optical sensor configured to generate an image of a first side of an article and a processor operatively connected to the optical sensor. The processor is configured to generate an image of the article with the optical sensor, the image including features that are illuminated by an external illumination source through the article, and generate an output indicating if the article is authentic in response to the features corresponding to a predetermined plurality of features that are generated from another image of the article corresponding to features in the generated image and in response to a cryptographic signature corresponding to feature data that are extracted from the other image corresponding to a valid cryptographic signature of a predetermined party.

1. A system for authentication of an article comprising:
an optical sensor configured to generate an image of the article; and a processor operatively connected to the optical sensor, the processor being configured to:
generate an image of the article with the optical sensor, the article being illuminated by an external illumination source that projects light through the article;identify a region of interest in the image of the article including a non-cloneable feature;generate a first feature vector corresponding to the non-cloneable feature in the region of interest in the image of the article;receive data corresponding to a second feature vector and a cryptographic signature generated by a sending party;generate a distance measurement between the first feature vector and the second feature vector;verify that the cryptographic signature corresponds to the second feature vector; andgenerate an output indicating that the article is authentic in response to the distance measurement being less than a predetermined threshold and to verification that the cryptographic signature corresponds to the second feature vector.
