A testbed for evaluating security and robustness of steganography techniques

This paper proposes a testbed environment for evaluating the security and robustness of the major steganography techniques. The testbed environment allows the embedding of messages into still images, preprocessing to detect the hidden messages and a post processing stage to perform further analysis on an image. The environment was used to test the survivability of stego-images. This was achieved by using cover images and hidden messages of different formats and sizes. A large set of images were subjected to a wide range of steganography tools. The output of the pre-processing stage achieved a high success rate in indicating the presence of hidden messages in the tested images.
