| Abstract: |
The invention relates to a method for integrating hidden information in a set of notes. According to the method, the geometrical shape and/or the mutual geometrical proportion of geometrical elements of the set of notes are modified relatively to the original version, based on a predetermined key, so that the modifications carry the information to be integrated in digital form and do not reduce the readability of the set of notes. The inventive method allows especially for the integration of an identification marking in a set of notes and the retention of said marking when the set of notes is subjected to copying or to simple manipulations.
