In this paper, the authors explore, as many as possible, algorithms and techniques that have been used by many researchers to provide security to the information using steganography. Steganography is the science that deals with communicating secret data by using any of the multimedia carrier, such as digital image, audio and video files. Cryptography is also used for securing the secret message but in this, feature is visible though it is not readable so point of attack is evident. So, primary goal is to hide the very existence of the embedded data.
