An Improved Image Steganography using High Potential Pixel Value for Secret Data Hiding

In this proposed methodology introduced a new secret data hiding scheme for the image that is based on energy and cost matrix. The aim of steganography is to hide an information message within harmless cover medium in such way that it's not possible even to observe that secrete information. It doesn't replace cryptography however rather boosts the security using its obscurity options. In the projected its obscurity features. In the proposed algorithm we have used energy and cost matrix based pixel calculation for hide the data which improve the security level. In encryption, information is transformed in such a way that it cannot be detect by hacker. But during encryption, message is changed so it become distorted and intruder may suspect about the presence of important information. The output of our technique provides higher results because with the assistance of cropping an increased security than hiding data highly secured random theory based energy and cost matrix based pixels thus with this object destined steganography. The proposed shows good result as compare to other method on the basics of PSNR (Peak-Signal-to-Noise Ratio), mean square error (MSE) Payload capacity (PC) and structural similarity index measurement (SSIM). A part from performance parameter result like PSNR and MSE proposed method shows good result in terms of visually. Some method shows good PSNR and other parameter but when visual not shows good pixel values. Proposed Scheme shows good result in terms of visually as well as standard parameters.
