Optimized Image Steganalysis through Feature Selection using MBEGA
Feature based steganalysis, an emerging branch in information forensics, aims at identifying the presence of a covert communication by employing the statistical features of the cover and stego image as clues/evidences. Due to the large volumes of security audit data as well as complex and dynamic properties of steganogram behaviours, optimizing the performance of steganalysers becomes an import...
متن کاملAdvantages of Using Feature Selection Techniques on Steganalysis Schemes
Steganalysis consists in classifying documents as steganographied or genuine. This paper presents a methodology for steganalysis based on a set of 193 features with two main goals: determine a sufficient number of images for effective training of a classifier in the obtained high-dimensional space, and use feature selection to select most relevant features for the desired classification. Dimens...
متن کاملAn Improved Image Steganalysis Using a Novel Feature Selection Algorithm Based on Artificial Bee Colony
One of the most important phases of pre-processing is Feature selection, which can improve the predictive accuracy of steganalysis. In this study, we have presented a novel feature selection-based method to image steganalysis for detecting stego images from cover images based on artificial bee colony (ISBC). The experiments show that the proposed method is easy to be employed for steganalysis p...
متن کاملOn Optimal Feature Selection Using Intelligent Optimization Methods for Image Steganalysis ⋆
The purpose of image steganalysis is to detect the presence of hidden messages in cover images. Steganalysis can be considered as a pattern recognition process to decide which class a test image belongs to: the innocent photographic image or the stego-image. We compare harmony search algorithm and particle swarm optimization algorithm based feature selection for image steganalysis. Experiment r...
متن کاملImprove Steganalysis by MWM Feature Selection
Steganography is the art of invisible communication. It is derived from the ancient Greece thousands of years ago (Johnson & Jajodia, 1998; Kahn, 1996), and grow rapidly in the past few years along with the development of digital technology and the internet. Modern steganography has been widely used in various scenarios such as secret communication, digital rights management, data temper detect...
