Emerging Internet technologies fetch high demand to provide secure data during the communication process. For this purpose, the steganography approach plays an imperative role in the world. Steganography is basically the art of hiding useful secret data in the cover media, such as images, audio or video. Consequently, it allows protected communication without any information to any unintentional user. There are different researchers already proposed own idea about the data hiding techniques but the quality of improve the quality. In this paper, a comparative analysis of various stegno-techniques along with the advantages and disadvantages are discussed. The process of image steganography is also described along with an example.
