Abstract

A consumable can be used to securely send data to devices. A security platform can produce a consumable, for example an ink cartridge, with data to be uploaded onto a device, such as a printer. If the consumable and device can perform a successful authentication, broadcast data can be delivered to the device via the consumable. Such techniques can help ensure that authentic consumables are being used in authentic devise. Further, such techniques can enable a licensing model where different consumables can be configured with different data to enable or disable different features of the device.

Claims (27)

1. A method for securing a printer, comprising:

generating a data item, the data item including security data and broadcast data, wherein the security data includes an authorization token and a cartridge revocation list, and the broadcast data includes at least one of a critical firmware fix, specific configuration data, or predictive maintenance data;

dividing the broadcast data into a first portion and a second portion;

loading, by a security system, the first portion into a first cartridge and the second portion into a second cartridge;

coupling the first and second cartridges to the printer;

performing an authentication between each of the first and second cartridges and the printer using security information included in the first and second cartridges; and

when the authentication is successful, uploading the first and second portions from the first and second cartridges, respectively, to the printer to provide an entirety of the broadcast data to the printer.

2. The method of claim 1 further comprising:

when the authentication is unsuccessful, disabling one or more features of at least one of the printer and the first and second cartridges.

3. The method of claim 1 further comprising:

uploading printer data from the printer to one of the first and second cartridges.

4. The method of claim 1 , further comprising:

directing the printer, using the security data, to enable one or more features of the printer.

5. The method of claim 1 , further comprising:

directing the printer, using the security data, to disable one or more features of the printer.

6. A cartridge device, comprising:

circuitry configured to

store, in a memory of the cartridge device, a first portion of broadcast data of a data item, the data item including security data and the broadcast data, wherein the security data includes an authorization token and a cartridge revocation list, and the broadcast data includes at least one of a critical firmware fix, specific configuration data, or predictive maintenance data;

perform an authentication between the cartridge device and a printer using security information included in the cartridge device when the cartridge device and the printer are coupled together; and

when the authentication is successful, upload the first portion of the data item from the cartridge device to the printer, wherein

a second portion of the broadcast data is included in another cartridge device communicatively coupled to the printer, and

the first and second portions stored in the cartridge device and the other cartridge device together form an entirety of the broadcast data to be uploaded to the printer.

7. The device of claim 6 , wherein the circuitry is further configured to

when the authentication is unsuccessful, upload additional security data to the printer to disable one or more features of the printer.

8. The device of claim 6 , wherein the circuitry is further configured to receive printer data from the printer.

9. The device of claim 6 , wherein the circuitry is further configured to direct the printer, using the security data, to enable one or more features of the printer.

10. The device of claim 6 , wherein the circuitry is further configured to direct the printer, using the security data, to disable one or more features of the printer.
