Claim One:
1. A method of authenticating an object, comprising: providing an object having a surface having a first plurality of elements, each element having a position defined by a random process resulting from a manufacturing variation, representing an authentic pattern, and an associated digital file encoding the authentic pattern, comprising a cryptographic digital hash based of the positions of the first plurality of elements, the encoding being an irreversible compression of data and providing an error correction tolerance during authentication to a predetermined amount of statistical deviation from the authentic pattern represented by the positions of the first plurality of elements, from which authenticity of the object may be assured and from which the authentic pattern comprising the position defined by the random process resulting from the manufacturing variation, of each of the first plurality of elements, cannot be ascertained; capturing at least two images of the surface of the object, comprising a second plurality of elements, having an image precision greater than the manufacturing variation; analyzing the at least two different images with at least one automated processor to determine the positions of the second plurality of elements in the captured at least two images, wherein the second plurality of elements has at least one difference with respect to the first plurality of elements; authenticating the object, by the at least one automated processor, based on the determined positions of the second plurality of elements from the captured at least two images, and the associated digital file, by verifying a correspondence of the determined positions of the second plurality of elements with respect to the authentic pattern of the positions of the first plurality of elements encoded in the associated digital file and the error correction tolerance to the predetermined amount of statistical deviation from the authentic pattern; and outputting a message corresponding to a result of the authenticating.
