Nascondere le informazioni significa riservatezza, accesso non autorizzato al contenuto e indisponibilità. La steganografia è l'arte e la scienza che nasconde qualsiasi informazione attraverso un supporto di copertura appropriato come immagini, testi, audio e video. Il watermarking digitale è un tipo di marcatore che viene incorporato in modo nascosto in un segnale tollerante al rumore come immagini, audio e video. Di solito viene utilizzato per identificare la proprietà del copyright. La crittografia è il metodo di conversione del testo in chiaro in testo cifrato. Anche la crittografia visiva è un tipo di tecnica crittografica che permette di criptare le informazioni visive in modo tale che la decriptazione possa essere eseguita dal sistema visivo umano senza l'ausilio di computer. Per una comunicazione sicura attraverso supporti digitali di copertura, l'implementazione a cascata di crittografia, filigrana digitale invisibile/steganografia e crittografia visiva può creare uno dei migliori livelli di sicurezza nel campo della sicurezza delle informazioni. La steganalisi è l'abilità e la scienza di individuare i messaggi nascosti dal mezzo di copertura stego. Cerca di trovare ulteriori informazioni dall'oggetto stego, come il tipo di algoritmo di incorporazione, la lunghezza del messaggio ecc.
