Product Description
Abstract—An Improved Inverted LSB Image Steganography, In this paper, an improvement in the plain LSB based image steganography is proposed and implemented. The paper proposes the use of bit inversion technique to improve the stego-image quality. Two schemes of the bit inversion techniques are proposed and implemented. In these techniques, LSBs of some pixels of cover image are inverted if they occur with a particular pattern of some bits of the pixels. In this way, < Final Year Projects > less number of pixels is modified in comparison to plain LSB method. 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. The proposed bit inversion technique provides good improvement to LSB steganography. This technique could be combined with other methods to improve the steganography further.
