About The Book

La steganografia � una forma di occultamento dei dati; consiste nel proteggere le informazioni incorporandole in supporti digitali a fini di identificazione, tutela del copyright e trasmissione di messaggi segreti. La steganografia nel campo audio rappresenta una disciplina complessa, poich� il sistema uditivo umano (HAS) � estremamente sensibile. Uno dei principali ostacoli all'occultamento dei dati nell'audio consiste nello sviluppo di un sistema in grado di incorporare una grande quantit� di dati senza compromettere la qualit� del suono. In questa ricerca sono stati progettati due approcci di steganografia per nascondere dati segreti in file multimediali audio (MP3). Il primo metodo proposto si basa sull'incorporazione di testo crittografato tra i frame (BF) nel file MP3, mentre il secondo si basa sull'incorporazione di testo crittografato prima del primo frame (BAF) nel file MP3. Dopo aver esaminato i due approcci proposti, � stato confermato che il primo metodo (BF) � migliore perch� ha la capacit� di incorporare circa 40 MB senza compromettere la qualit� del suono e richiede 134,2 secondi per l'incorporazione e 2618,2 secondi per l'estrazione, mentre il secondo metodo (BAF) ha dimostrato la sua capacit� di incorporare circa 8 KB (al massimo) senza compromettere la qualit� del suono.
