In this paper a method for embedding the secret data into the container image is considered. The method is based on specifics of the spectral properties of ad hoc two-dimensional discrete orthogonal transform. The values of functions forming the basis of this transform are `chaotically' distributed. Two ideas provide the ground for the synthesis of these bases. Firstly, the 1D M-transforms, that were introduced and investigated in certain particular cases by H.-J. Grallert. Secondly, the application of introduced by I. Kàtai canonical number systems in finite fields to numerating the input image pixels.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
