steganography
This term describes the art of hiding a secret in plain sight, where the very existence of the communication is concealed. It differs from cryptography, which scrambles a message to make it unreadable; steganography ensures that an observer does not even realize a hidden message is present.
In modern technical contexts, this usually involves manipulating the least significant bits of a digital file, such as an image or audio clip, to embed data without altering the perceived quality of the carrier. Because it is an uncountable noun referring to a field of study or a practice, it does not take a plural form and requires partitive phrases like a piece of or an instance of when referring to specific applications.
