Printing content on a print medium based upon the authenticity of the print medium
First Claim
1. A mobile telecommunications device comprising:
- a media feed path for receiving a print medium;
a drive means for transporting the print medium through the media feed path;
a sensor module located in the media feed path for sensing data encoded on a surface of the print medium in the media feed path, the data encoding a print media identifier which uniquely identifies the print medium and at least part of a digital signature of the print media identifier;
means for determining the print media identifier and the at least part of the digital signature from the sensed data;
means for determining whether the digital signature is authentic; and
a printer module located in the media feed path for printing content on the print medium in the media feed path upon the digital signature being authentic.

Abstract
A mobile telecommunications device having a printer module and sensor module in a media feed path is disclosed. A drive means transports a print medium through the media feed path. The sensor module senses data encoded on a surface of the print medium in the media feed path. The data encodes a print media identifier which uniquely identifies the print medium and at least part of the digital signature of the print media identifier. The print media identifier and at least part of the digital signature are determined from the data, and it is determined whether the digital signature is authentic. The printer module prints content on the print medium in the media feed path if the digital signature is authentic.
