We propose a new family of echo hiding procedures designed to work with audio files with ternary watermarks. Most attention is paid to the case when the image is used as a watermark. The possibility of using a melody for this purpose is also mentioned. A human is supposed to be a detector to prove the presence of a watermark in the audio file. The approach employs infinite impulse response (IIR) filters of a particular form that provides a capability insertion a few symbols into a fragment of the container. The suggested method’s payload and resistance to various attacks exceed the parameters of the classical implementation of echo hiding.
