This paper contains research on and methods of determining values for basic parameters of steganographic
systems. In particular, a parameter of concealing the presence of information in a digital environment is researched.
Using this particular parameter increases the degree of protection of a message introduced into a digital
environment. This parameter is one of the fundamental ones in case of implementation of a steganalysis
system. Besides that, this paper contains a review of parameters of redundancy of a digital environment and the
parameter of steganogram resistance to technological transformations in digital environments.
