A Survey Paper on Video Steganography

In today�s world security become a major issue, so it is very important to hide the data in such a way that attacker cannot access it. Data is mostly in form of text, image, audio and video. So steganography is a best scheme for hiding the data from attacker. Steganography is a one type of algorithm that can be applied on text, image, audio and video file and the secret data generally in form of text, image, audio and video. The method of hiding secret information in video file is called video steganography. In this paper a review on different video steganography technique are discussed. Different spatial domain, frequency domain techniques of video steganography have been presented in this paper.
