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 until someone finds the secret message in whatever is being used to hide it.
The word steganography comes from Ancient Greek, combining a root meaning "cover" or "roof" with a suffix for writing. It originally referred to the art of hiding messages within other text so that they remain undetected.
