Abstract
Image Steganography is the method of hiding the presence of data in cover images .Here we propose the revised version of Roshan Shetty B R et al. whose work was inspired by C. Chang et al. In earlier work only the RED & GREEN components of cover image pixel was used and reference matrix used was of order 27 x 27 and embedding capacity was 3 bits per pixel. In this paper we use RED, GREEN & BLUE components of cover image pixel and reference matrix of order 9 x 9. Hence, the embedding capacity is 4.5 bits per pixel. Prior to embedding the data we use compression and encryption so that more and various digital media are securely embedded in cover image.
