Due to the technological advancements and menace of hacking, security has become the most important criterion in all fields. In order to achieve high information security in this regard, a method called steganography is employed. Steganography is the science of embedding data in any cover object without causing any discrepancy in the cover. In this paper, a novel information hiding method has been proposed using image steganography in spatial domain to improve the security and the payload in a gray scale image. In the proposed method, the maximum number of bits that has to be altered is two for embedding three bits in a pixel. It is also found that the proposed method has improved capacity with good imperceptibility.
