An Efficient Steganographic Method by using Image Fragments With High Security
B. Elangovan and S. Mohana

Abstract: Picture quality and undetectability are the key aspects of steganography. In this study, the proposed framework uses a novel approach to enhance the steganographic scheme with optimized picture quality and higher anti-steganalysis capability. To achieve this, the secret image is hidden in the carrier image by creating layers in Stegoimage. Differing from previous works, this method retains the quality of the carrier image and it doesn’t depend on the size of the carrier image and shows better imperceptibility. To abate to the damage in the reconstructed carrier image, the secret image is divided into two segments, one with odd bytes and the other with even bytes. These are embedded into the carrier image in the form of layers rather than embedding it on the carrier image itself. A pass-key is used for security purpose. This is done after pointing out the related approaches and then highlighting this model’s contributions with respect to the embedding and extraction processes.
