The invention relates to a device for reading a message which comprises: a means for reading biometric data of a holder of the medium; a means for capturing, on a medium, an encoded message comprising elementary message units, said message having noise that consists of marking defects of the message on said medium which are random and unpredictable for each elementary message unit; a means for reducing the noise of the captured message, based on biometric data; and a means for decoding at least one portion of the message in which the noise has been at least partially removed. In certain embodiments, the decoding means uses redundancies of the message with the noise removed to determine at least one portion of the encoded message. |
