Discussions of steganography generally use terminology analogous to and consistent with conventional radio and communications technology. However, some terms appear specifically in software and are easily confused. These are the most relevant ones to digital steganographic systems:

The ''payload'' is the data covertly communicated. The ''carrier'' is the signal, stream, or data file that hides the payload, which differs from the ''channel'', which typically means the type of input, such as a JPEG image. The resulting signal, stream, or data file with the encoded payload is sometimes called the ''package'', ''stego file'', or ''covert message''. The proportion of bytes, samples, or other signal elements modified to encode the payload is called the ''encoding density'' and is typically expressed as a number between 0 and 1.

In a set of files, the files that are considered likely to contain a payload are ''suspects''. A ''suspect'' identified through some type of statistical analysis can be referred to as a ''candidate''.
