An Easy yet Effective Method for Detecting Spatial Domain LSB Steganography
This addresses the issue of detecting manipulated stego images used for secret communication, which is a concern in security and forensic fields, but appears to be an incremental improvement as it focuses on a specific detection method without claiming broad novelty.
The paper tackles the problem of detecting spatial domain LSB steganography in digital images, presenting a method that is described as effective, though no concrete performance numbers are provided in the abstract.
Digitization of image was a revolutionary step for the fields of photography and Image processing as this made the editing of images much effortless and easier. Image editing was not an issue until it was limited to corrective editing procedures used to enhance the quality of an image such as, contrast stretching, noise filtering, sharpening etc. But, it became a headache for many fields when image editing became manipulative. Digital images have become an easier source of tampering and forgery during last few decades. Today users and editing specialists, equipped with easily available image editing software, manipulate digital images with varied goals. Photo journalists often tamper photographs to give dramatic effect to their stories. Scientists and researchers use this trick to get theirs works published. Patients' diagnoses are misrepresented by manipulating medical imageries. Lawyers and Politicians use tampered images to direct the opinion of people or court to their favor. Terrorists, anti-social groups use manipulated Stego images for secret communication. In this paper we present an effective method for detecting spatial domain Steganography.
