About The Book

Il watermarking digitale � una tecnica utilizzata per la protezione del copyright e l'autenticazione mediante l'incorporazione di un identificatore distintivo nel contenuto digitale. Il concetto chiave consiste nell'estrarre questo identificatore nascosto, come una firma o un logo, da un documento in cui � stato incorporato prima della trasmissione. Questo libro presenta un'implementazione di successo del watermarking di immagini a doppio host utilizzando un'unica immagine di filigrana, un metodo mai raggiunto in precedenza. In tutti i modelli proposti, l'immagine identificatrice viene divisa in due canali separati e incorporata in due diverse immagini di copertura. Durante l'estrazione, entrambe le immagini nascoste vengono recuperate e combinate per ricostruire l'identificatore originale. I modelli sono stati simulati utilizzando il software MATLAB e hanno dimostrato prestazioni superiori rispetto agli approcci pi� avanzati.
