Abstract

Methods and systems are described to determine authenticity of a consumable product. The determining of authenticity may include communicating with a listing engine that contains a list of identifiers for consumable products classified as non-authentic, installing a consumable product in a host device where the consumable product stores an identifier in memory, and determining whether the consumable product matches one of the identifiers.

First claim

What is claimed is:

1. A method of determining an authenticity of a consumable product, comprising:
communicating with a listing engine that contains a list of identifiers for consumable products classified as non-authentic, wherein the identifiers for consumable products classified as non-authentic are associated with at least one of:
a geography of occurrence, and
a frequency of failed authentications;

installing the consumable product in a host device, wherein the consumable product stores an identifier in a memory; and
determining whether the identifier stored in the consumable product matches one of the identifiers for consumable products classified as non-authentic.

2. The method of claim 1 , further comprising verifying only a portion of the list of identifiers based on at least one of
a geography of the host device, and
the frequency of failed authentication.

3. The method of claim 1 , further comprising denying an authentication request for the consumable product during an authentication session based on the identifier stored in the consumable product being included in the list of identifiers.

4. The method of claim 3 , comprising preventing usage of the consumable product in response to denying the authentication request.

5. The method of claim 1 , further comprising downloading a portion of the list of identifiers to the host device based on available or allocated memory in the host device.

6. The method of claim 1 , wherein the host device is a printer and the consumable product is a print cartridge.

7. A device comprising:
a processor; and
a non-transitory storage medium storing instructions executable on the processor to:
communicate, over a network, with an engine to download, from the engine, a list of identifiers of consumable products classified as non-authentic;
store the downloaded list of identifiers at the device;
update, by communicating with the engine over the network, the downloaded list of identifiers stored at the device using an update to the list of identifiers at the engine;
in response to connection of a first consumable product to the device, determine whether a consumable product identifier stored in the first consumable product matches any identifier in the updated list of identifiers stored at the device; and
deny authentication of the first consumable product in response to determining that the consumable product identifier matches an identifier in the updated list of identifiers stored at the device.

8. The device of claim 7 , wherein the instructions are executable on the processor to initiate an authentication session between the device and the first consumable product.

9. The device of claim 8 , wherein the denying of authentication is during the authentication session.

10. The device of claim 7 , wherein the device is a printer and the first consumable product is a print cartridge.

11. The device of claim 7 , wherein the instructions are executable on the processor to perform the updating on a periodic basis.

12. The device of claim 7 , wherein the instructions are executable on the processor to perform the updating in response to a user request.

13. The device of claim 7 , wherein the instructions are executable on the processor to perform the updating in response to the update to the list of identifiers becoming available at the engine.

14. The device of claim 7 , wherein the identifiers in the updated list of identifiers stored at the device are associated with at least one of:
a geography of occurrence of a failed authentication, and
a frequency of failed authentications.

15. A non-transitory computer readable storage medium storing computer readable instructions that when executed cause a device comprising a processor to:
recognize that a consumable product is connected to the device;
update a list of identifiers of consumable products classified as non-authentic, the list of identifiers stored at the device, and the updating comprising communicating, over a network, with a listing engine that contains a listing engine list of identifiers of consumable products classified as non-authentic;
initiate an authentication session between the device and the consumable product; and
authenticate, using the updated list of identifiers, the consumable product during the authentication session.

16. The non-transitory computer readable storage medium of claim 15 , wherein the computer readable instructions when executed cause the device to deny an authentication request from the consumable product during the authentication session in response to determining that an identifier of the consumable product is in the updated list of identifiers.

17. The non-transitory computer readable storage medium of claim 15 , wherein the identifiers in the updated list of identifiers are associated with at least one of:
a geography of occurrence of a failed authentication, and
a frequency of failed authentications.

18. The non-transitory computer readable storage medium of claim 15 , wherein the instructions upon execution cause the device to perform the updating on a periodic basis.

19. The non-transitory computer readable storage medium of claim 15 , wherein the instructions upon execution cause the device to perform the updating in response to a user request.

20. The non-transitory computer readable storage medium of claim 15 , wherein the instructions upon execution cause the device to perform the updating in response to an update to the list of identifiers becoming available at the listing engine.
