Steganography is an important field of research in recent years to embed a range of data, it is the science that hide information in cover medium without being accompanied by any effect or distortion in that medium. Nevertheless, most of the modern researches focus on hiding information in image according to its popularity. This paper studies the Least Significant Bit (LSB) (1-LSB, 2-LSB and 3-LSB) with one or RGB color based Steganography, The LSB algorithm has experimented on Bitmap 24 bits format as cover image to generate a stego images. The aim of this paper is to carry out various types of image steganography technique for purpose of identifying various principles of image steganography in terms of visual effectiveness and efficiency. However, the algorithm that has been chosen for this purpose is discussed in details in this paper. The visual effectivity of the stego were measured by comparing the histograms of the stego and cover images. In this study we used Mean Squared Error MSE calculation and discussed the implementation of this algorithm in detail. The results from experiments prove that algorithm is not affected by different visual characteristics of the cover images in so doing, the perceptual distortion to the cover image is nearly negligible and unlikely to be detected by simple visual inspection.
