PROCEDURE FOR MARKING BINARY CODED DATA SETS |
摘要 |
<p>Disclosed is a method of marking binary-coded data sets, especially image data or audio signals, by applying at least one information unit to a data set. The invention is characterised by the generation of a discrete position sequence for the application of information units to the data set to be marked, taking into account data-specific characteristics and using a key; and by the fact that the information unit to be applied is written and read at the positions established in the position sequence in the data set.</p> |
