Abstract

A method of retrieving a ringtone using a print medium is disclosed. The method starts by determining a print media identifier from the print medium using a sensor module of a mobile telecommunications device. The print media identifier is linked to the ringtone. The method then retrieves, using the mobile telecommunications device, the ringtone.

Claims

1. A method of retrieving a ringtone using a print medium, the method comprising the steps of:

sensing data encoded on a surface of the print medium using a sensor module of a mobile telecommunications device, the data encoding at least a print media identifier and a two-dimensional coordinate grid with respect to the surface of the print medium;

determining a print media identifier from the sensed data;

determining the position of the sensor module relative to the surface of the print medium from the sensed data; and

retrieving, using the mobile telecommunications device, the ringtone referenced by the print media identifier and a region on the surface of the print medium, the position of the sensor module being within said region.

2. The method as claimed in claim 1 further comprising displaying on a display of the mobile telecommunications device information associated with or representative of the ringtone.

3. The method as claimed in claim 1, wherein the ringtone is stored in an audio library on the mobile telecommunications device.

4. The method as claimed in claim 1, wherein the print medium is provided with a first coded data in a first format and a 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 the two-dimensional coordinate grid, the second format being a two-dimensional pattern.

5. The method as claimed in claim 1, wherein the data further encodes a digital signature associated with the print media identifier, the method including:

determining from the sensed data the digital signature;

determining whether the digital signature is authentic; and

retrieving, if the digital signature is authentic, the ringtone.

6. The method as claimed in claim 5, wherein the digital signature includes at least one of:

a random number;

a secret-key digital signature; and

a public-key digital signature.
