Manipulierte Bilder werden zu einem immer gröÿeren Problem in der aktuellen Berichterstattung und sie verursachen in vielen Fällen Empörung unter den Lesern. In dieser Diplomarbeit werden verschiedene Ansätze aus der aktuellen Forschung aufgezeigt, die zur Erkennung von manipulierten digitalen Bildern benutzt werden können. Hierbei liegt der Schwerpunkt besonders auf verschiedenen statistischen Ansätzen von Farid, Johnson und Popescu. Ein Abriss über die wichtigsten inhaltsbasierten Algorithmen wird ebenfalls gegeben. Weiterhin wird für die Algorithmen, die im Hinblick auf technische Realisierbarkeit, Laufzeit und ein breites Spektrum von möglichen Szenarien vielversprechend wirken, eine Automatisierung entwickelt, die die Analyse ohne we...
