Enhanced Capacity Steganography Using Multi-Channel Architecture

Image Steganography is the popular method to hide sensitive information behind image and that is not the only reason, the hidden information is invisible to naked eyes so that no one can easily predict the secret information behind the image. In this paper we are introducing a new technique for image stenography which increases the capacity of information carried by image. Image stenography was the research trend among researcher to secure and increase the capacity of transferring information. Here we are exploiting the multi channel architecture of RGB colour image to increase capacity. The idea behind the proposed approach is to embed information in all three channels of image instead of one channel of RGB image to hide information. Proposed approach significantly increased the information embedding capacity of cover image with losing the invisibility of secret information.
