Steganography is the art of hiding important data by embedding secret message within other file. The least significant bit (LSB) is one of the most important considerations when one want to solve such problems. LSB substitution method exchanges some LSB of the cover-image with the secret data. In this paper, data hiding method using simple LSB substitution is proposed. The main goal of the presented method is to increase the embedding capacity and improve the image quality of the stego-image. The experimental results show better performance of the proposed method compared to the corresponding methods, in terms of PSNR and the capacity. The effectiveness of the model is estimated from the viewpoint of both the amount of data hidden and the image quality of the cover image.
