Equivalence Analysis Among DIH, SPA, and RS Steganalysis Methods

摘要

Steganography of images based on the use of the LSB (Least Significant Bit), SPA (Sample Pair Analysis), RS (Regular and Singular groups) method and DIH (Difference Image Histogram) method are three powerful steganalysis methods. A comparison analysis among DIH, SPA, and RS method is discussed, and a comparison of their proofs is presented. The process of proving includes three parts, and an equivalence relationship proposition is respectively proofed in every section. This proving offers a theory base for the study of an approach that can resist these three kinds of steganalysis methods synchronously.
