Method, device and system for storing, encoding and decoding information based on codes with error detection capacity

A device for storing encoded information with error correction capacity, comprising:

• a first physical layer, comprising an unalterable graphic printout of a message encoded using a code with error correction capacity;
• at least a second physical layer, comprising an alterable graphic printout according to the physical/chemical properties of said second physical layer, wherein said alteration generates one or more errors in the information of the message encoded in the first physical layer;
• wherein the message of the first physical layer and the errors generated therein by alteration of the graphic printout of the second physical layer are encoded according to an extended code, wherein said extended code comprises one or more error definition and correction rules in said message, from the optical information associated with the superimposition formed by the unalterable graphic printout of the first physical layer and by the alterable graphic printout of the second physical layer, whereby the information associated with the errors provides enhanced information with respect to the code of the message of the first physical layer.
