In recent years Steganography plays an important role in secure communication. Steganography is a technique of embedding secret information into cover media, like image, video, audio and text, so that only the sender and the authorized recipient can detect the presence of secret information. In this paper we propose Spatial Domain Steganography using 1-Bit Most Significant Bit (MSB) with chaotic manner. The cover image is decomposed into blocks of 8*8 matrix of equal size. The first block of cover image is embedded with 8 bits of upper bound and lower bound values required for retrieving payload at the destination. The mean of median values and difference between consecutive pixels is determined to embed payload in 3bits of Least Significant Bit (LSB) and one bit of MSB in chaotic manner. It is observed that the capacity and security is improved compared to the existing methods with reasonable PSNR. ©2010 IEEE.
