Abstract

A method of gaining access to a resource using an access token linked to a print medium, comprising the steps of: determining a print media identifier from the print medium using a sensor module of a mobile telecommunications device, the print media identifier having been linked to the access token; identifying, using the mobile telecommunications device and the print media identifier, the access token; and, causing the access token to be supplied to a system, wherein the system is configured to authenticate the access token and, if the authentication succeeds, provide access to the resource.

Claims

1. A method of gaining access to a resource using an access token linked to a print medium, comprising the steps of:

determining a print media identifier from the print medium using a sensor module of a mobile telecommunications device, the print media identifier having been linked to the access token;

identifying, using the mobile telecommunications device and the print media identifier, the access token; and

,

causing the access token to be supplied to a system, wherein the system is configured to authenticate the access token and, if the authentication succeeds, provide access to the resource.

2. The method as claimed in claim 1, wherein information associated with or representative of successful authentication is at least one of:

displayed on a display of the mobile telecommunications device; and

printed on a print medium by a printer module of the mobile telecommunications device.

3. The method as claimed in claim 1, wherein the resource is at least one of:

an application;

a utility;

a service;

a game;

an accessory;

a driver;

an interface;

an operating system;

a patch;

an update;

a tool;

a file;

an image;

audio;

video;

a document;

a web page; and

components thereof.

4. The method as claimed in claim 1, wherein the access token is indicative of at least one of:

a key;

a cryptographic key;

a password;

a code;

biometric information; and

a digital signature.

5. The method as claimed in claim 1, wherein the system is a server in communication with the mobile telecommunications device.

6. The method as claimed in claim 1, wherein the access token is identified from a database and the database is at least one of:

stored locally at the mobile telecommunications device; and

stored remotely at a server.

7. The method as claimed in claim 1, wherein access tokens are periodically supplied to the system.

8. The method as claimed in claim 1, wherein the print medium is provided with first coded data in a first format and second coded data in a second format, the first coded data encoding first information and the second coded data encoding second information, at least some of the first information being indicative of the print media identifier, the first format being a linear pattern, at least some of the second information being indicative of the print media identifier and of a two-dimensional coordinate grid, the second format being a two-dimensional pattern.

9. The method as claimed in claim 1, wherein the sensor module is used to link the access token to the print media identifier.

10. The method as claimed in claim 1, wherein the print medium is provided with coded data in a format, the coded data encoding information, at least some of the information being indicative of the print media identifier.

11. The method as claimed in claim 10, wherein the method includes:

when the print medium is presented in a media feed path of the mobile telecommunications device, reading, using the sensor module, at least some of the coded data; and

determining, using the at least some read coded data, the print media identifier.

12. The method as claimed in claim 11, wherein the media feed path includes a printer of the mobile telecommunications device.

13. The method as claimed in claim 10, wherein the format is a linear pattern.

14. The method as claimed in claim 10, wherein the information is further indicative of a two-dimensional coordinate grid, and the format is a two-dimensional pattern.

15. The method as claimed in claim 10, wherein the information is further indicative of a digital signature associated with the print media identifier, the method including:

determining, by reading at least some of the coded data using the sensor module, the digital signature; and

identifying, if the digital signature is authentic, the access token.

16. The method as claimed in claim 15, wherein the digital signature includes at least one of:

a random number;

a secret-key digital signature; and

a public-key digital signature.

17. The method as claimed in claim 10, wherein a printer module of the mobile telecommunications device prints at least some of the coded data on the print medium.

18. The method as claimed in claim 10, wherein the method includes paying for the access token using the mobile telecommunications device.

19. The method as claimed in claim 14, wherein the access token is associated with a region of the print medium, the method including:

reading, using the sensor module, at least some of the coded data;

determining, using the at least some read coded data, a position of the sensor module relative to the print medium; and

,

identifying, if the determined position is within the region, the access token.

20. A print medium comprising a surface provided with coded data, the coded data indicative of a print media identifier, the print media identifier linked to an access token, the print media identifier able to be determined using a sensor module of a mobile telecommunications device, the access token identifiable from a database using the print media identifier.
