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.

Claims

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.

2. The method of claim 1, wherein the printed material further comprises an overlay layer printed over and obscuring the layer of non-visible indicia.

3. The method of claim 2 wherein the overlay layer comprises an optically encoded image.

4. The method of claim 1 wherein the action of decoding the optically encoded authentication indicia includes positioning an optical decoding device over the layer of non-visible indicia prior to creating the optical image.

5. The method of claim 4 wherein the optical decoding device comprises a lenticular lens.

6. The method of claim 1 wherein the optical image is captured digitally using a digital imaging device and wherein the action of decoding the optically encoded authentication indicia is carried out using the optical image and a software-based digital decoder.

7. The method of claim 1 wherein the emitting substance emits one of the set consisting of infrared light and ultraviolet light when stimulated with electromagnetic radiation.

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.

9. The method of claim 8 further comprising:

decoding the optically encoded authentication image.

10. The method of claim 9 wherein the action of decoding the optically encoded authentication image is carried out using a lenticular lens disposed intermediate the print region and the imaging device during the action of creating an image.

11. The method of claim 9 wherein the optically encoded authentication image is captured in digital form and is decoded using a software-based digital decoder.

12. The method of claim 8 wherein at least a portion of the second layer is printed over at least a portion of the first layer.

13. The method of claim 12 wherein the at least a portion of the first layer is obscured by the at least a portion of the second layer in a second predetermined electromagnetic wavelength range.

14. The method of claim 13 wherein the second predetermined electromagnetic wavelength range comprises the visible light region of the spectrum.
