Steganography is the technique with which the confidential data is hidden under the cover medium such as image, without reflecting any clue on the cover image. Many algorithms are designed to provide the security for the communication of data over the Internet. The good steganographic algorithm is identified by the performance of the algorithm measured with the help of the parameters such as PSNR, MSE, robustness and capacity to hide the information in the cover image. This paper analyzed the Digital Image Steganographic algorithms in spatial and frequency domain.
