US 12,614,046 B2 · Mark authentication with distortion tolerance

Abstract

Methods, systems, and apparatus, including medium-encoded computer program products, for mark authentication with distortion tolerance. An electronic signature can be obtained as the data series for a candidate mark. The data series values of the electronic signature can be transformed to generate two or more transformed data series versions of the electronic signature. Hash identifiers for the electronic signature and for the two or more transformed data series versions of the electronic signature can be derived. The hash identifiers can be used to retrieve a set of two or more results from a database of genuine mark signatures. At least one electronic signature retrieved for at least one of the two or more results from the database can be compared with the electronic signature for the candidate mark to confirm the candidate mark is genuine.

Dependent claims

A system comprising:

a user interface device;
and
one or more computers operable to interact with the user interface device, characterized in that the one or more computers are programmed to perform operations in accordance with machine-readable instructions, the operations comprising
obtaining an electronic signature for a candidate mark in an image,
using a distortion accommodation process that transforms a data series of the electronic signature for the candidate mark to obtain a transformed data series of the electronic signature that corrects distortion of values in the data series of the electronic signature for the candidate mark, and
authenticating the candidate mark using the transformed data series of the electronic signature for the candidate mark and a data series of an electronic signature of a genuine mark.
