Sobre IBD

Obwohl digitale Medien in den letzten Jahren gewaltiges Wachstum erfahren haben, ist die Gewährleistung der Authentizität der Daten, um die Identität des Besitzers oder Senders zu garantieren, Urheberrechte durchzusetzen, den Nachweis der Unversehrtheit und Integrität zu erbringen oder Manipulationen zu erkennen weitgehend ungelöst. Digitale Wasserzeichenverfahren bieten hier Lösungen. Sie erlauben den Nachweis von Authentizität oder Integrität, indem Informationen direkt in das Datenmaterial eingefügt werden. Die eingebrachte Information ist nicht wahrnehmbar und so mit den Daten verwoben, daß einfaches Entfernen unmöglich ist, ohne das Datenmaterial zu beschädigen. Ziel des Buches ist es, digitale Wasserzeichenverfahren für Multimediadaten vorzustellen, zu beschreiben und zu bewerten. Die beigefügte CD-ROM ermöglicht es, Markierungstechniken beispielhaft auszuprobieren, das Testmaterial veranschaulicht die Ergebnisse.
