Abstract

An authentication system, method and article for memorabilia and other forms of articles wherein a first image-bearing medium is affixed to the article with a tamper-proof adhesive. A unique code number is imprinted on the medium. A certificate of authenticity is provided for the article and includes a second image-bearing medium with an identical unique code number. A list of unique code numbers is maintained to enable a purchaser of the article to register that article such that the purchaser or a subsequent purchaser can verify the authenticity of the authenticated article.

Claims

1. An authentication system for an article comprising:

a. an article for which authentication is desired;

b. a first image-bearing medium affixed to the article with an adhesive to be tamper proof, the medium having imprinted thereon a unique code number;

c. a certificate of authenticity for the article, and including thereon a second image-bearing medium with an identical unique code number; and

d. a list of unique code numbers with a statement of the respective product to which each unique code number applies.

2. The system of claim 1 wherein the first and second image-bearing media each include a light diffracting pattern.

3. The system of claim 2 wherein at least one of the light diffracting patterns includes a hologram.

4. The system of claim 2 wherein the light diffracting pattern includes an optically generated diffraction pattern.

5. The system of claim 2 wherein the light diffracting pattern includes a mechanically generated diffraction pattern.

6. The system of claims 1 or 2 wherein the image of the first image-bearing medium and the image of the second image-bearing medium are identical.

7. The system of claims 1 or 2 wherein the image of the first image-bearing medium and the image of the second image-bearing medium are different.

8. The system of claim 1 wherein the list of unique code numbers is accessible by a purchaser of the article to enable the purchaser to verify the authenticity of the article through the unique code number.

9. The system of claim 1 wherein the article includes an autograph.

10. The system of claim 9 wherein the article is a baseball.

11. The system of claim 1 wherein the first image-bearing medium includes a holographic image on a substrate with an overlying clear thin film with an outer layer and the unique code number is imprinted on the outer surface of the film.

12. An authentication method for an article comprising the steps of:

a. providing an article for which authentication is desired;

b. affixing to the article a first image-bearing medium with an adhesive so as to be tamper proof;

c. providing on the first image-bearing medium a unique code number;

d. providing a certificate of authenticity for the article and including thereon a second image-bearing medium with an identical unique code number; and

e. providing a list of unique code numbers with a statement of the respective products to which each of the unique code numbers apply, and providing in the list the unique code number for the article and a brief description of that article.

13. The method of claim 12 wherein the first and second image-bearing media include light diffracting patterns.

14. The method of claim 13 wherein either the first or the second image-bearing medium includes a hologram.

15. The method of claim 14 wherein the brief description identifies the article and a feature of the article for which authentication is desired.

16. The method of claim 15 wherein the feature is an autograph of a sports personality.

17. In an authentication system for enabling an article to be authenticated, wherein a certificate of authenticity is provided with each product and a list of unique code numbers describing each article and the associated code number, each article having at least one unique feature, such as a person'"'"'s autograph, and having a first image-bearing medium affixed to the article with an adhesive so as to be tamper proof, the first image-bearing medium having imprinted thereon a unique code number and the unique code number and a brief description of the article being stated in the list, the corresponding certificate of authenticity including a second image-bearing medium having the same unique code number as the unique code number associated with the article.

18. The system of claim 17 wherein the first and second image-bearing media include light diffracting patterns.

19. The system of claim 18 wherein at least one of the image-bearing media includes a hologram.

20. The system of claim 19 wherein the unique feature includes an autograph.
