A Survey On Digital Video Steganography Techniques Used For Secure Transmission Of Data

Image Processing

Recent advances in information technology have made quick delivery and sharing of multimedia information possible. But these advances in technology are leading breaches to information security and personal information. Now days, it is very risky to handle the data in internet against intruders. Data is generally in the form of text, audio, video and image. With the development of the technology, people have tend to figure out methods which are not only capable in hiding a message, but also capable of hiding the existence of a message. Steganography was introduced as a result of such research work. Steganography is the process of hiding secret information inside a data source which is referred as cover medium. Steganography has applications in different fields such as defence, medical, online transactions etc. It is mainly used in situations where the confidentiality of information is of prime importance in communication. Based on type of cover medium there is different type of steganography i.e. audio, video, text, image etc. Video Steganography is the process in which message is embedded inside the video type of cover medium in such manner that is existence. In this paper we analyze different video steganography techniques and their comparative study. To improve embedding process in terms of robustness and visual quality advance LSB (Least Significant Bit) method is used in proposed model.
