Steganography
Steganography is the practice of concealing a message (file, image, video) with another file, image, video, etc.
Cryptography vs Steganography
- [[!Cryptography]] protects the content of a message. Steganography is concerned with concealing the fact that a secret message is being sent and its contents.
- Steganography enhances [[!Cryptography]] alone because the [[!encryption]] does not attract attention to itself. Any [[!Cipher]] may be broken, but you have to know it is a cipher first.
Digital stenography
- Media files are particularly ripe for steganography due to their large size.
- Messages might have multiple levels of [[!encryption]]. Ex: an image which spells out a word encoded as a song.
Examples
- [[!Herodotus]] records an incident where a message was marked on a servants scalp and then sent once his hair had regrown.
- [[!Invisible ink]]
