System and method for authenticating objects using non-visually observable encoded indicia
First Claim
1. A method for authenticating an object, the method comprising:
- providing at least one object having a print region with printed material contained thereon comprising a layer of non-visible indicia, at least a portion of which is formed from an emitting substance that emits at least one wavelength of light outside a visible range of an electromagnetic spectrum when stimulated with electromagnetic radiation, the non-visible indicia comprising optically encoded indicia;
creating an optical image of the layer of non-visible indicia with an imaging device such that the layer of non-visible indicia can be perceived by a human eye viewing the optical image;
decoding the optically encoded authentication indicia; and
comparing the decoded authentication indicia to expected authentication indicia to verify the authenticity of the object.

Abstract
An authentication method comprises providing at least one object having a print region with printed material contained thereon, the print layer comprising a layer of non-visible indicia. At least a portion of the non-visible indicia is formed from an emitting substance that emits at least one wavelength of light outside a visible range of an electromagnetic spectrum when stimulated with electromagnetic radiation. The non-visible indicia comprises optically encoded indicia. The method further comprises creating an optical image of the layer of non-visible indicia with an imaging device such that the layer of non-visible indicia can be perceived by a human eye viewing the optical image. The method still further comprises decoding the optically encoded authentication indicia and comparing the decoded authentication indicia to expected authentication indicia to verify the authenticity of the object.

8. A method for authenticating an object having a print region for receiving printed material thereon, the method comprising:
-
applying to the print region of the object a first print layer comprising first indicia that are visible in a first predetermined electromagnetic wavelength range; applying to the print region of the object a second print layer comprising second indicia that are not visible in the first predetermined electromagnetic wavelength range; creating an image of the object with an imaging device adapted for viewing the first indicia in the first predetermined electromagnetic wavelength range, the image including the print region of the object; and analyzing the image of the object to verify that the first indicia are present on the print range of the object, wherein at least one of the set consisting of the first indicia and the second indicia comprises an optically encoded authentication image. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16, 17, 18)
