Abstract

An apparatus and method are disclosed for tamper-proofing two-dimensional, optical, computer readable bar codes, including QR Codes. QR Codes, like traditional bar codes, contain computer readable content not cognizable by the human mind. The present invention teaches means of securing this content from would-be thieves and forgers motivated to overlay authorized, original content with unauthorized, replacement content.

Claims

1. An security badge for securing a two-dimensional bar code, the security badge comprising:

a printed QR Code encircled by a plurality of color-coded rings, wherein each color-coded ring represents a predefined category selected from the group consisting of;

a category representative of subject matter displayed on a website to which a URL referenced in the QR Code resolves, and a category representative of a Trademark class established by the United States Trademark Office.

2. The security badge of claim 1, wherein one or more of the color-coded rings overlap the QR Code.

3. The security badge of claim 2, wherein one or more of the color-coded rings underlap the QR Code.

4. The security badge of claim 1, wherein one or more color-coded rings comprise rigid, tubular, three-dimensional rings affixed to the security badge and overlapping the QR Code.

5. The security badge of claim 1, wherein a color of an area encircled by the one or more color-coded rings is representative of a predefined category not represented by the one or more color-coded rings.

6. The security badge of claim 5, wherein the area encircled by the one or more color-coded rings is partially overlaid with the QR Code.

7. The security badge of claim 1, wherein the one or more color-coded circles overlap and underlap one another.

8. The security badge of claim 1, wherein the one or more color-coded circles comprise non-uniform radii.

9. The security badge of claim 1, wherein each of the one or more color-coded circles comprises non-uniformly located centers within the QR Code.

10. The security badge of claim 9, wherein the area encircled by the one or more color-coded rings is overlaid with the QR Code.

11. The security badge of claim 1, wherein the one or more color-coded rings are textured.

12. The security badge of claim 11, wherein the texture comprises Braille identifying the predefined category.

13. The security badge of claim 1, wherein the one or more color-coded rings are chemiluminescent.

14. The security badge of claim 1, wherein one of the one or more color-coded rings geometrically inscribe the data matrix of the QR Code.

15. The security badge of claim 1, wherein the QR Code comprises between one and four non-linear border edges, the non-linear border edges representative of one of:

a date upon which the QR Code was printed, a location where the QR Code was printed, a target audience, and effectiveness estimate.

16. The security badge of claim 1, further comprising:

a plurality of printed stripes underlaying the QR Code and the one or more color-coded rings, wherein each of the printed stripes is representative of secondary category selected from the group consisting of;

a category representative of subject matter displayed on a website to which a URL referenced in the QR Code resolves, and a category representative of a Trademark class established by the United States Trademark Office, a category representative of a type of real estate offering, and category representative of a price range, a category representative of an age range for which the website is intended, and a category representative of a geographic location.

17. The security badge of claim 16, further comprising a passive RFID tag for demodulating a radio-frequency signal, the RFID tag identifying the owner of the QR Code.

18. An security badge for securing a two-dimensional bar code, the security badge comprising:

a printed bar code encircled by a plurality of color-coded rings, wherein each color-coded ring represents a predefined category selected from the group consisting of;

a category representative of subject matter displayed on a website associated with the bar code, a geographic location of a business managing the bar code, and a category representative of a Trademark class established by the United States Trademark Office.
