Abstract

A method for creating a secure document, registering the secure document and verifying the authenticity of the secure document includes receiving a print object that has content. A security feature, including an identifier, is created and is associated with the content. The identifier may be a barcode. The barcode may represent a character string. The security feature may include the identifier barcode and a decoy barcode that is not associated with the content. The identifier barcode (or the character string represented by the barcode) and the content are transmitted to a database for storage. Once stored, the identifier and the content are considered to be registered. A print object that includes the security feature and the content is then transmitted to a printer for printing.

Claims

1. A method for creating a secure document and verifying that the secure document is authentic, the method comprising:

receiving a print object, designating content to be printed, at a first processor;

the first processor generating a unique identifier for the print object associating the unique identifier with the content;

the first processor transmitting the print object content and associated unique identifier to storage;

the first processor generating decoy identifiers and overlaying the unique identifier with at least one decoy identifier;

the first processor transmitting the print object content and associated unique identifier overlayed with the decoy identifier to a printer for printing the print object content and the decoy overlayed unique identifier as a secure document;

detecting the printed secure document with the decoy overlaid unique identifier to verify authenticating of the secure document;

transmitting the detected print object content and decoy overlaid unique identifier to a second processor associated with the storage;

the second processor filtering the decoy identifier from the unique identifier;

the second processor comparing the unique identifier with unique identifiers stored in the storage; and

outputting an indicator that the unique identifier is in the storage, thereby authenticating the printed secure document.

2. The method of claim 1 wherein the unique identifier overlaid with the decoy identifier comprise a security feature for the secure document.

3. The method of claim 2 wherein filtering the decoy identifier comprises using a logical or physical filter to remove the decoy identifier from the security feature leaving only the unique identifier.

4. The method of claim 1 wherein the unique identifier and decoy identifier are printed using ultraviolet responsive ink or toner.

5. The method of claim 1 wherein the unique identifier is a first two dimensional (2-D) barcode having a first color, the decoy identifier is a second 2-D barcode having a second color, and overlaying the first 2-D barcode with the second 2-D barcode creates a security feature for the secure document.

6. The method of claim 5 wherein filtering the decoy identifier comprises using a filter of the second color to remove the decoy identifier from the security feature.

7. The method of claim 5 wherein:

the first color and the second color are ultraviolet responsive colors that fluoresce when illuminated using ultraviolet light, or

the first color and the second color are infrared responsive colors that fluoresce when illuminated using infrared light, or

the first color and the second color are colors that are visible when illuminated using light in the visible spectrum.

8. The method of claim 1 further comprising:

capturing, using a camera, at least part of the content;

transmitting, by the second processor, the at least part of the content to the storage, wherein receiving the at least part of the content includes receiving data indicating that the detected at least part of the content matches the stored content.

9. The method of claim 1 further comprising:

capturing, using a camera, at least part of the content;

receiving, from the storage a corresponding part of the content; and

determining, by the second processor, that the camera captured part of the content matches the received part of the content.
