Abstract
Um zu erreichen, dass von einer Kopie (1a, 1b) eines Datenträgers (1) eruierbar wird und bleibt, welches die kopierende Instanz war, wird auf einem Bereich (3) des Datenträgers (1) für Nutzinformation ver teilt eine Identifikation (5a, 5b) vorgesehen, und zwar für jeden Empfänger (A, B) spezifisch. Durch enge Kopplung von Identifikation (5a, 5b) mit der an alle Empfänger (A, B) identisch verteilten Nutzin formation wird erreicht, dass auch bei wiederholtem Kopieren die Identifikation (5a, 5b) mindestens ebenso lange interpretierbar bleibt, wie die aus dem Bereich (3) des Trägers (1) aufgebrachte Nutzinfor mation. In order to achieve that of a copy (1a, 1b) of a Data carrier (1) can and will be determined which one the copying instance was on an area (3) of the data carrier (1) for useful information ver shares an identification (5a, 5b), and specific for each recipient (A, B). By close coupling of identification (5a, 5b) with the all recipients (A, B) are distributed identically formation is achieved that even with repeated Copy the identification (5a, 5b) at least remains interpretable for as long as that from the Area (3) of the carrier (1) applied useful information mation.
