Data Security is that the most crucial think about a communication network. Data security is achieved by cryptography and data concealing. Steganography is one of the info concealing technique; here any form of signal is concealing by exploitation a picture, audio or video. In an exceedingly spatial domain steganography, most typically the info is embedded into a LSB’s of the cover image pixels. As a result of it maintain the standard of the stego image as like as cover image instead of embedded into MSB’s. To embedding into a LSB’s of cover image (R, G, B plane) researchers are using different types of pixel indicating methods, random embedding, edge based embedding in spatial domain or applying completely different reworks in transform domain. In this paper, for spatial domain steganography noise based embedding technique is proposed; it is entirely different from the out there techniques. In this paper two copies of JPEG, PNG, GIF, or BMP etc., images are used. One is taken as a reference image and noise is added onto that. Supported this reference image knowledge is embedded into the LSB’s of cover image. Proposed system using salt and pepper noise for data embedding, it is an ON, OFF noise. Based on added salt, pepper, and no noise portions of reference image completely different range of bits are embedded into the cover image. The result is analyzed by using MSE, PSNR and capacity performance metrics.
