For rapid development of network technology data is needed to be communicated over the network. Although network transmission is convenient and fast, the data is often attacked. Steganography is used to hide the data in the images. Images used for carrying data are called cover images and images with embedded data are called stego images. Data is embedded in the images in such a way that it should be detected by human eyes and it should be robust so that it offers resistance to various image processing methods and compression. In this survey paper our focus is on development and current status on data hiding techniques in spatial domain of images. Keywords-Steganography, stego image,least significant bit(LSB), optimal pixel adjustment process (OPAP), diamond encoding(DE).
