In the recent years image steganography techniques can be divided into two groups: those in the ImageDomain and those in the Transform Domain. Image – also known as spatial – domain techniques embed messages in theintensity of the pixels directly, while for transform – also known as frequency – domain, images are first transformed andthen the message is embedded in the image.Image domain techniques encompass bit-wise methods that apply bit insertion and noise manipulation and aresometimes characterized as ―simple systems‖. The image formats that are most suitable for image domainsteganography are lossless and the techniques are typically dependent on the image format.
