Review on Video Steganography

Abstract

To maintain the secrecy of information, various information hiding techniques are used. Steganography is one of them, which means hide information inside another digital media like text, image, audio, video etc. without being detected by human visual system. Although many steganographic techniques, in the literature, have been developed for this purpose, most of them distort the quality of the host-signal during data embedding and the changes will be become visible to the human eye especially for those signals distributed via the Internet which must be processed by a low bit rate compression due to bandwidth limitations. Therefore, the challenge is to create a steganographic technique that is able to hide acceptable amount of data without altering the quality of the host-signal. This paper presents the steganography of an Image on a multiple frame video using Frame Decomposition Technique in which LSB Algorithm is used on multiple frame video for Steganography. The aim of the research is to get image so image decomposition is required for this type of steganography. It declares that same image which steganography has been done will extract at output phase. Message hiding technique using LSB algorithm has been used.
