Abstract
Several works have been proposed and implemented for image Steganography using LSB substitution. In this paper, a module based LSB substitution method is implemented, which is further improved by using a novel bit inversion technique. The substitution method hides the message data after compressing smoother areas of the image in a lossless way, resulting in fewer number of modified cover image pixels. After this, a bit inversion technique is applied. In the bit inversion technique, certain LSBs of pixels of cover image are changed if they occur with a particular pattern. In this way, less number of pixels is modified. So PSNR of stego-image is improved. For correct de-steganography, the bit patterns for which LSBs has inverted needs to be stored within the stego-image somewhere.
