Novel Approach to Image Steganalysis (A Step against Cyber Terrorism)

Abstract

Steganography is a technique of hiding secret messages in the image in such a way that no one apart from the sender and intended recipient suspects the existence of the message. Image Steganography is frequently used by Terrorist Networks for securely broadcasting, dead-dropping and communicating the secret information over the internet by hiding the secret information in the Images. As a result it becomes the most preferred tool to be used by Terrorists and criminal organizations for achieving secure CIA (Confidentiality, Integrity and Availability) compliant communication network capable of penetrating deep inside the civilian population. Steganalysis of Image (Identification of Images containing Hidden Information) is a challenging task due to lack of Efficient Algorithms, High rates of False Alarms and above all the High Computation Costs of Analyzing the Images. In this paper a Novel Technique of Image Steganalysis is devised which is not only Fast and Efficient but also Foolproof. The results shown in the paper are obtained using programs written in MATLAB© Image Processing Tool Box.
