Data Hiding in Grayscale Image using Least Significant Bit Technique and Discrete Wavelet Transform

Abstract

In this paper, we present a model for data hiding using modified least Significant Bit and DWT concept to further improve the ability to embed as a picture good (EC).From the begin, each high-quality pixel produces 4 new pixels. The puzzle facts is concealed in all the four conveyed pixels. via then the pixels are fixed to improve the concept of the stego-pics. There are four separate stego-pictures crafted from the four unmistakable revised pixels. each stego-photo disguises one piece for every pixel. For Stego-photos, the typical peak signal-to-noise ratios (PSNR) the proposed procedure successfully withstand against RS-stego examination
