Abstract

A method that involves product authentication includes associating a serial number of a device with a first consumer product, thereby allowing an authenticity of the first consumer product to be verified using the device, determining whether the first consumer product is authentic using the serial number, and associating the serial number of the device with a second consumer product after the first consumer product is sold and after the device has been returned for recycling, thereby allowing an authenticity of the second consumer product to be verified using the device.

Claims

1. A method that involves product authentication, comprising:

associating a serial number of a device with a first consumer product, thereby allowing an authenticity of the first consumer product to be verified using the device;

determining whether the first consumer product is authentic using the serial number; and

associating the serial number of the device with a second consumer product after the first consumer product is sold and after the device has been returned for recycling, thereby allowing an authenticity of the second consumer product to be verified using the device.

2. The method of claim 1, wherein the act of determining whether the first consumer product is authentic comprises using the serial number and a number.

3. The method of claim 2, wherein the number is a random number.

4. The method of claim 1, further comprising determining a secret code based on the serial number, wherein the act of determining whether the first consumer product is authentic comprises using the serial number and the secret code.

5. The method of claim 1, wherein the act of determining whether the first consumer product is authentic comprises using the serial number to generate a reference authentication number in accordance with a predetermined algorithm.

6. The method of claim 5, wherein the act of determining whether the first consumer product is authentic further comprises comparing the reference authentication number with a calculated authentication number transmitted from the device.

7. The method of claim 6, further comprising providing an output for transmission through the network based on a result of the act of comparing.

8. The method of claim 7, wherein the output comprises information regarding the first consumer product.

9. A system for product authentication, comprising:

a processor that is configured for;

associating a serial number of a device with a first consumer product, thereby allowing an authenticity of the first consumer product to be verified using the device;

determining whether the first consumer product is authentic using the serial number; and

associating the serial number of the device with a second consumer product after the first consumer product is sold and after the device has been returned for recycling, thereby allowing an authenticity of the second consumer product to be verified using the device.

10. The system of claim 9, wherein the processor is configured to use the serial number and a number to determine whether the first consumer product is authentic.

11. The system of claim 10, wherein the number is a random number.

12. The system of claim 9, wherein the processor is also configured for determining a secret code based on the serial number, and wherein the processor is configured for determining whether the first consumer product is authentic by using the serial number and the secret code.

13. The system of claim 9, wherein the processor is configured for determining whether the first consumer product is authentic by using the serial number to generate a reference authentication number in accordance with a predetermined algorithm.

14. The system of claim 13, wherein the processor is configured for determining whether the first consumer product is authentic by also comparing the reference authentication number with a calculated authentication number transmitted from the device.

15. The system of claim 14, wherein the processor is also configured for providing an output for transmission through the network based on a result of the comparing.

16. The system of claim 15, wherein the output comprises information regarding the first consumer product.

17. A computer program product having a non-transitory medium storing a set of instructions, an execution of which will cause a method to be performed, wherein the set of instructions comprises:

instruction for associating a serial number of a device with a first consumer product, thereby allowing an authenticity of the first consumer product to be verified using the device;

instruction for determining whether the first consumer product is authentic using the serial number; and

instruction for associating the serial number of the device with a second consumer product after the first consumer product is sold and after the device has been returned for recycling, thereby allowing an authenticity of the second consumer product to be verified using the device.

18. The computer program product of claim 17, wherein the instruction for determining whether the first consumer product is authentic comprises instruction for using the serial number and a number.

19. The computer program product of claim 18, wherein the number is a random number.

20. The computer program product of claim 17, further comprising instruction for determining a secret code based on the serial number, wherein the instruction for determining whether the first consumer product is authentic comprises instruction for using the serial number and the secret code.

21. The computer program product of claim 17, wherein the instruction for determining whether the first consumer product is authentic comprises instruction for using the serial number to generate a reference authentication number in accordance with a predetermined algorithm.

22. The computer program product of claim 21, wherein the instruction for determining whether the first consumer product is authentic further comprises instruction for comparing the reference authentication number with a calculated authentication number transmitted from the device.

23. The computer program product of claim 22, further comprising instruction for providing an output for transmission through the network based on a result of the comparing.

24. The computer program product of claim 23, wherein the output comprises information regarding the first consumer product.
