Abstract

A method for validating a quick response code includes steps or acts of: receiving a captured enhanced quick response code that included a static component and a dynamic component; validating the quick response code in the static component using the auxiliary data in the dynamic component; and returning a token when the quick response code is validated.

First claim

The invention claimed is:

1. A method for validating a quick response code, said method comprising:
using an input/output interface coupled to a processor device, performing:
receiving a captured enhanced quick response code comprising a static component and a dynamic component;
wherein the static component comprises a traditional quick response code;
wherein the dynamic component is coupled with the static component and comprises auxiliary data used to validate the quick response code;
validating the quick response code in the static component using the auxiliary data in the dynamic component; and
returning a token when the quick response code is validated.

2. The method of claim 1 , wherein validating the quick response code comprises: retrieving information from a location indicated by the static component; comparing the retrieved information with the auxiliary data contained within the dynamic component; and determining whether the retrieved information matches the auxiliary data.

3. The method of claim 2 , further comprising:
generating the enhanced quick response code with both the static component and the dynamic component; and
attaching the auxiliary data to the dynamic component.

4. The method of claim 3 , further comprising encrypting the auxiliary data with a key known only to the validation engine.

5. The method of claim 4 , wherein the auxiliary data is at least one selected from a group consisting of: visual data and radio frequency signals.

6. The method of claim 5 , wherein the auxiliary data encodes at least one of: location, time, time-range, and location-boundary.

7. The method of claim 5 , wherein the visual data is a graphical image produced by a display.

8. The method of claim 5 , wherein the visual data is alphanumeric.

9. The method of claim 5 , further comprising:
watermarking the visual data as a countermeasure to unauthorized replication.

10. The method of claim 5 , wherein the auxiliary data comprises a radio frequency component.

11. The method of claim 10 , wherein the radio frequency component is a near field communication tag.

12. A method for validating a quick response code, comprising:
using an input/output interface coupled to a processor device, performing:
capturing an enhanced quick response code comprising a static component and a dynamic component;
wherein the static component comprises a quick response code with a location identifier;
wherein the dynamic component is coupled with the static component and comprises auxiliary data used to validate the quick response code;
transmitting both components of the captured enhanced quick response code to a validation engine for validating the quick response code; and
receiving a token from the validation engine when the quick response code is validated.

13. The method of claim 12 , further comprising:
processing the quick response code when it is determined that the token is a valid token.

14. The method of claim 12 , further comprising encrypting the auxiliary data with a key known only to the validation engine.

15. The method of claim 14 , wherein the auxiliary data is at least one selected from a group consisting of: visual data and radio frequency signals.

16. The method of claim 15 , wherein the auxiliary data encodes at least one of: location, time, time-range, and location-boundary.

17. The method of claim 15 , wherein the visual data is a graphical image produced by a display.

18. The method of claim 15 , wherein the visual data is alphanumeric.

19. The method of claim 15 , further comprising:
watermarking the visual data as a countermeasure to unauthorized replication.

20. The method of claim 15 , wherein the auxiliary data comprises a radio frequency component.
