Steganalysis Based on Regression Model and Bayesion Network

2009 
In this paper, we propose a feature generation and classification approach for universal steganalysis based on Genetic Algorithm (GA) and higher order statistics. The GA is utilized to select a subset of candidate features, a subset of candidate transformations to generate new features. The Logistic Regression Model and Bayesion Network Model are then used as the classifier. Experimental results show that the GA based approach increases the blind detection accuracy and also provides a good generality by identifying an untrained stego-algorithm.
