Steganography

Pronunciation

• UK IPA: /ËŒstɛɡ.É™nˈɒɡ.ɹə.fi/
• US IPA: /ËŒstÉ›.É¡ÊŒnˈɔ.ɡɹʌ.fi/

Origin

From Ancient Greek στεγανός (steganos, "cover, roof") + γράφω (graphō, "I write")

Noun

1. The practice of hiding messages, so that the presence of the message itself is hidden, often by writing them in places where they may not be found.
2. Specifically: the use of small files in computers to communicate secret information.

Usage notes

Steganography differs from cryptography in that cryptography conceals only the content of the message through encryption. Steganography conceals the presence of the message itself.
