In digital steganography, electronic communications may include steganographic coding inside of a transport layer, such as a document file, image file, program or protocol.
Both steganography and digital watermarking employ steganographic techniques to embed data covertly in noisy signals.
This fact can be used in steganography, where an algorithm interprets a binary data file differently to reveal hidden content.
It would today be regarded as a simple form of steganography.
These applications fall under the term inter-protocol steganography.
The simple representation also lends itself to steganography.
The puzzles focused heavily on data security, cryptography, and steganography.
Typical network steganography methods involve modification of the properties of a single network protocol.
