Abstract: The study proposed the method of control information covert introduction in voice data, taking into account the energy distribution of their frequency components on the frequency axis. The use of subband projections for covert coding instead of the pseudo-random sequence used in spectrum increase method allows to increase the secrecy with the same probability of error.
