Abstract :
Data hiding is a process of hiding information. There are various techniques used for hiding data. Data hiding can be done in audio, video, image, text, and picture. This method is steganography i.e., embedding data in another data. Usually we use image for data hiding especially digital images. For embedding data in images there are many techniques are used. Some techniques will embed data but embedding cause some distortion to image, some techniques can embed only small amount of data, and some techniques will cause distortion during the extraction of data. So the various methods that are used for embedding and extraction of data are described in this.
