Abstract

There are several powerful steganalytic methods for images in the spatial domain, which are based on higher order statistics. We propose a generic methodology to prepare higher order steganalytic methods from spatial domain for application in the transformed domain. This paper presents 72 new systematically designed methods that are derived from the spatial domain. Their reliability and the precision of their length estimation is evaluated based on 1700 million attacks. We present the contribution of the proposed methods in terms of detection power and precision compared to prior art and determine how properties like image size and JPEG quality influence the ranking of the proposed attacks.
