Secure Secret Information Transmission with Audio-Video Steganography Using Encryption and Data Authentication

Video steganography is an emerging field of research in recent years. In the recent years due to advancements in transmission channel huge amount of data can be transmitted using channel bandwidth. Huge amount can be transmitted over the channel using video steganography in secure manner because due to availability of number of frames in a file data can be embedded secretly behind any frame. Various approaches had been used for embedding of secret information behind the cover object behind cover object in video steganography. LSB, random pixel selection, frequency division, time domain division and RGBGBR approaches had been used for hiding of secret information. In this paper secure steganography has been done using MLSB and phase coding approach for data embedding behind video and audio signals. This approach provides better steganography than other approaches.
