Abstract

A method of using a mobile device to authenticate a printed token and output an image associated with the token, the mobile device comprising a sensor and processing means, the method comprising the steps of: using the sensor to sense coded data on the printed token; using the processing means to determine, from the sensed coded data, at least an identity of the token; authenticating the token using the identity; based on at least the identity, determining an image associated with the token; and outputting the image from the mobile device in a visible form.

Claims

1. A method of using a mobile device to authenticate a printed token and output an image associated with the token, the mobile device comprising a sensor and processing means, the method comprising the steps of:

using the sensor to sense coded data on the printed token;

using the processing means to determine, from the sensed coded data, at least an identity of the token;

authenticating the token using the identity;

based on at least the identity, determining an image associated with the token; and

outputting the image from the mobile device in a visible form.

2. A method according to claim 1, wherein the mobile device includes a display and the outputting step includes displaying the image on the display.

3. A method according to claim 1, wherein the mobile device includes a printhead and the outputting step includes printing the image onto a print medium with the printhead.

4. A method according to claim 3, wherein mobile device includes a transmitter and a receiver, the step of determining the image associated with the token comprising:

sending first data to a remote computer system using the transmitter, the first data being indicative of at least the identity; and

receiving second data from the computer system via the receiver, the second data being indicative of the image.

5. A method according to claim 1, wherein mobile device includes a transmitter and a receiver, the method comprising:

using the processing means to determine, from the sensed coded data, at least part of a signature, the signature being a digital signature of at least part of the identity;

using the transmitter to send first data to a remote computer system, the first data being indicative of the identity and the at least part of the signature;

using the receiver to receive second data from the remote computer system in reply to the first data, the second data being indicative of whether the print medium is authentic based on the identity and the at least part of the signature.

6. A method according to claim 5, wherein the coded data includes a plurality of coded data portions, each coded data portion encoding:

the identity; and

,

at least a signature fragment;

wherein the method includes sensing a plurality of coded data portions thereby to determine a plurality of signature fragments representing the at least part of the signature.

7. A method according to claim 6, comprising sensing the plurality of coded data portions as the print medium moves past the sensor whilst moving along a print path defined in the mobile device.

8. A method according to claim 7, wherein each coded data portion encodes a signature fragment identity, and wherein the method includes:

determining the signature fragment identity of each determined signature fragment; and

determining, using the determined signature fragment identities and the corresponding signature fragments, the at least part of the signature.

9. A method according to claim 6, wherein the plurality of signature fragments are indicative of the entire signature.

10. A method according to claim 6, wherein the coded data includes a plurality of tags, each coded data portion being formed from at least one of the tags.

11. A method according to claim 5, wherein the second data is further indicative of at least one of:

padding associated with the signature;

a private key; and

a public key.

12. A method according to claim 1, comprising:

using the processing means to determine, from the sensed coded data, at least part of a signature, the signature being a digital signature of at least part of the identity;

determining, using the at least part of the signature, a determined signature;

generating, using the determined signature and a public key stored in the mobile device, a generated identity;

comparing the identity to the generated identity; and

authenticating the print medium using the results of the comparison.

13. A method according to claim 12, wherein the mobile device includes a receiver, the method comprising the steps, performed before the step of generating the generated identity, of:

using the receiver to receive data indicative of the public key; and

storing the public key in memory of the mobile device.

14. A method according to claim 13, wherein the mobile device includes a transmitter, the method comprising the step of transmitting to a remote computer system a request for the public key, the receiver receiving the data indicative of the public key from the computer system in response to the request.

15. A method according to claim 12, further including the step of retrieving the key from a remote computer system prior to generating the generated identity.

16. A method according to claim 12, wherein the coded data includes a plurality of fragments of the signature, the method comprising determining a plurality of the signature fragments from the sensed coded data.

17. A method according to claim 16, wherein the coded data includes a plurality of coded data portions, each coded data portion encoding:

the identity; and

at least a signature fragment;

wherein the method includes sensing a plurality of coded data portions to thereby determine the plurality of signature fragments.

18. A method according to claim 17, wherein the plurality of coded data portions are sensed as the print medium moves past the sensor whilst moving along a print path defined in the mobile device.

19. A method according to claim 17, wherein each coded data portion encodes a signature fragment identity, and wherein the method includes:

determining the signature fragment identity of each determined signature fragment; and

determining, using the determined signature fragment identities, the determined signature.

20. A method according to claim 4, wherein the print medium includes second coded data, the method comprising the step of printing the image onto the print medium, such that the print medium becomes a further token associated with the image.
