<p>Disclosed is a method for processing input information and recordding the processed information in the form of 'distributed data pattern', where the printed distributed data pattern can be reprocessed in order to reconstruct the input information. The input information is not directly visible in the printed distributed pattern data. The method has the characteristic that each portion of the input information contributes to all portions of the printed distributed data pattern. Similarly the reprocessing has the characteristic that all portions of the printed distributed data pattern contribute to each portion of the reconstructed input information.</p> |
