Linguistic steganography is the scientic art of avoiding the conception of suspicion in covert communications by concealing data in a linguistic based textual cover. The goal is not to hinder the adversary from decoding the hidden message, but to prevent the arousal of suspicion in covert communications. Fundamentally, when using any steganographic technique if suspicion is raised, the goal of steganography is defeated regardless of whether or not a plaintext is revealed.

The NORMALS ensures that the communicating parties establish a secure covert channel for transmitting the hidden message covertly. In other words, NORMALS naturally camouflages the delivery of a hidden message in such a way as to appear legitimate and innocent.

The conclusion of NORMALS' experiment of word frequency is as follows. Since NLGS is based on a domain-specific subject, then when applying Zipf's law, NORMALS Cover should be similar to a Zipfian slope of its domain-specific subject (the unaltered authenticated data of the same domain that contains no hidden message), and it is not required to fully obey Zipf's law. To emphasize, if the Zipfian slope of the NORMALS' domain-specific subject (the unaltered authenticated data of the same domain that contains no hidden message) is equal to N value, then NORMALS Cover should be either equal or close to that N value.
