Abstract
Die Erfindung betrifft ein Verfahren zum Senden von Videodateien über ein Datennetz von einem Dienstanbieter an mindestens einen entfernt davon angeordneten Benutzer. Während der Sendedauer werden im Bereich (1) des Dienstanbieters aus den unverschlüsselten Videodaten (b) mit Mitteln der automatisierten Datenverarbeitung verschlüsselte Daten (d) und zum Entschlüsseln derselben notwendige und hinreichende Schlüsseldaten (c) erstellt, die verschlüsselten Daten (d) im Bereich des Dienstanbieters gespeichert, die Schlüsseldaten (c) an den Benutzer übertragen und bei diesem gespeichert. Zu einem späteren Zeitpunkt werden die verschlüsselten Daten (d) zum Bereich (3) des Benutzer gesandt und dort mit Hilfe der Schlüsseldaten (c) entschlüsselt.
