Abstract

An authentication method for authenticating an article in a device includes the steps of (a) reading an identification number stored on the article, (b) reading an authentication number stored on the article, (c) determining an input number based at least in part on the identification number, (d) applying an authentication function to the input number to calculate an output number, (e) determining that the article is authentic only if the authentication number corresponds to the output number, and (f) permitting use of the article in the device if the article is authentic, and disabling use of the article in the device if the article is not authentic.

Claims

1. A media holder for use with a media processor, the media holder comprising:

a transponder supported by the media holder, the transponder comprising;

an antenna; and

a memory disposed in communication with the antenna, the memory storing an identification number, a media type, and an authentication number, wherein the authentication number is at least partially a transformation of the identification number and the media type and the identification number is a transponder serial number sized between 32 and 64 bits.

2. The media holder of claim 1, wherein the transformation of the identification number comprises cryptographic methods.

3. The media holder of claim 1, wherein the transformation of the identification number and the media type comprises cryptographic methods.

4. The media holder of claim 1 further comprising a media supply spool configured to support a ribbon comprising panels, wherein the memory comprises a plurality of memory units, and wherein at least one of the plurality of memory units is configured to be locked.

5. The media holder of claim 4, wherein at least one of the plurality of memory units is configured to be locked in connection with media usage.

6. The media holder of claim 4, wherein at least one of the plurality of memory units is configured to be locked in connection with media usage of between 10 to 15 percent of the ribbon panels.

7. The media holder of claim 1, further comprising:

a media supply spool comprising;

a winding drum defining an axis and a first diameter, and

a flange defining a second diameter that is larger than the first diameter, wherein the antenna of the transponder is positioned on the flange and extends at least partially around the axis of the winding drum.

17. The media holder of claim 1 further comprising:

a media supply spool comprising;

a winding drum defining an axis and a first diameter, and

a flange defining a second diameter that is larger than the first diameter, wherein the antenna of the transponder is positioned on the flange and extends at least partially around the axis of the winding drum.

18. The media holder of claim 1 further comprising a media supply spool comprising media, wherein the media is a ribbon comprising ribbon panels.

19. The media holder of claim 4, wherein at least one of the plurality of memory units is configured to lock the identification number.

20. The media holder of claim 4, wherein at least one of the plurality of memory units is configured to lock the media type.

8. A media holder comprising:

a media supply spool comprising media, the media comprising a plurality of media panels; and

a transponder supported by the media holder, the transponder comprising;

an antenna; and

a memory disposed in communication with the antenna, the memory storing an identification number, an authentication number, a media type, a plurality of memory units that are configured to be locked, and wherein at least one of the plurality of memory units is configured to be locked in connection with usage between 10 to 15 percent of the media panels.

9. The media holder of claim 8, wherein the authentication number is at least partially a transformation of the identification number.

10. The media holder of claim 9, wherein the transformation of the identification number comprises cryptographic methods.

11. The media holder of claim 8, wherein the authentication number is at least partially a transformation of the identification number and the media type.

12. The media holder of claim 11, wherein the transformation of the identification number and the media type comprises cryptographic methods.

13. The media holder of claim 8, wherein the media is a ribbon comprising ribbon panels.

14. The media holder of claim 8, wherein at least one of the plurality of memory units is configured to lock the identification number.

15. The media holder of claim 8, wherein at least one of the plurality of memory units is configured to lock the media type.

16. The media holder of claim 8, wherein the media supply spool comprises:

a winding drum defining an axis and a first diameter, and

a flange defining a second diameter that is larger than the first diameter, and wherein the antenna of the transponder is positioned on the flange and extends at least partially around the axis of the winding drum.
