First Claim
Patent Images

1. A method, comprising:

  • acquiring first digital image data of an image of at least a portion of an inanimate physical object;

    analyzing the first image data to form a first digital fingerprint of the inanimate physical object, wherein the first digital fingerprint is responsive to at least one native feature of the inanimate physical object; and

    wherein forming the first digital fingerprint includes selecting an authentication region and extracting at least one feature vector from the selected authentication region, wherein the feature vector includes a plurality of color or gray scale numeric values corresponding to areas within the selected authentication region, the numeric values including at least one of a sum, average, maximum or other function of individual numeric values of a corresponding group of pixels forming a sub-part of the selected authentication region;

    storing the first digital fingerprint in a database record of a database system, wherein the database record is arranged to store history data in association with the first digital fingerprint;

    subsequent to storing the first digital fingerprint in the database record, identifying first information corresponding to a target inanimate physical object, wherein identifying the first information corresponding to the target inanimate physical object includes acquiring second digital image data of an image of at least a portion of the target inanimate physical object;

    acquiring second information associated with the target inanimate physical object;

    extracting features from the second digital image data to form a second digital fingerprint, wherein the second digital fingerprint is responsive to at least one native feature of the target inanimate physical object;

    querying the database system to identify a matching record based on the second digital fingerprint, wherein the matching identification is based on a threshold confidence level;

    in a case that a matching record is identified responsive to the querying, updating the matching record with an indication that the second digital fingerprint was matched to it; and

    updating the history data of said matching record based on said second information, including storing a measurement of a selected metric acquired by a sensor securely associated with the target inanimate physical object, and an indication of a time associated with the measurement.
