Note: Texte fondé sur des processus automatiques de reconnaissance optique de caractères. Seule la version PDF a une valeur juridique

What is claimed is:

1. An authentication device comprising:

a frame;

an internal reservoir disposed within the frame;

an uncured polymer or monomer disposed within the internal reservoir, wherein the polymer becomes

frangible upon being cured; and

at least one end of a security loop disposed within the polymer.

2. The device of claim 1, wherein the polymer is cured to form a cracked three dimensional identification scheme.

3. The device of claim 1, wherein light is distorted in a unique fashion by the cracked three dimensional identification scheme.

4. The device of claim 2, wherein removal of the at least one end of the security loop disposed within the polymer will change the three dimensional identification scheme of the device.

5. The device of claim 1, wherein the frame is transparent.

6. The device of claim 1, wherein dyes, metal particles, pigment particles, or other randomly-distributed authentication features are dispersed within the polymer prior to curing.

7. The device of claim 1, wherein the polymer interdigitates with the at least one end of the security loop.

8. A method of creating an authentication device comprising;

forming a container for an uncured polymer;

inserting at least one end of a security device through a wall of the container and into the uncured polymer;

curing the polymer; and

wherein curing of the polymer results in the polymer cracking and forming a frangible three-dimensional pattern in the cured polymer,

9. The method of claim 8, wherein light is distorted in a unique fashion by the cracked three dimensional identification scheme.

10. The method of claim 8, further comprising removal of the at least one end of the security device disposed within the polymer will change the three dimensional pattern in the cured polymer.

11. The method of claim 8, wherein the container is formed to be

transparent.

12. The method of claim 8, further comprising dispersing dyes, metal particles, pigment particles, or other randomly- distributed authentication features within the polymer prior to curing

13. The method of claim 8, further comprising imaging the frangible three-dimensional pattern.

14. The method of claim 13, wherein imaging is performed at multiple angles with respect to the authentication device.

15. The method of claim 13, further comprising imaging a fingerprint formed on the authentication device to form, a two-factor authentication device.

1.6. The method of claim 8, further comprising wherein the polymer interdigitates with the at least one end of the security device.

17. The method of claim 8, further comprising forming a physical barrier, a randomly formed, unique ID, and. a three dimensional tamper indicating pattern via the cured polymer.

18. The method of claim 1, wherein the authentication device is translucent yet appears hazy when viewed from an angle that is perpendicular to a face surface of the authentication device.
