    Abstract: A device for reading a message includes a reader to read biometric data of a holder of the medium and a scanner to capture, on a medium, an encoded message having elementary message units. The message includes a noise that consists of marking defects of the message on the medium which are random and unpredictable for each elementary message unit. A noise reducer to reduce the noise of the captured message based on biometric data. A decoder to decode at least one portion of the message in which the noise has been at least partially removed. Preferably, the decoder utilizes redundancies of the message with the noise removed to determine at least one portion of the encoded message.
