Research of Some Algorithms of Steganography

Abstract

The paper discusses some steganographic methods based on the use of the frequency characteristics of the speech signal. In particular, the authors consider a widely used method of steganography spreading and a new method of subband projections. The subband projections steganographic method is based on the application of sub-band analysis using subband matrices. For comparison, we considered steganographic methods used in the work of several different measures of differences. Besides, for comparison, we used the standard error, relative error, the
