Steganography over video file using Random Byte Hiding and LSB technique

Steganography is an art of hiding the secret information inside digitally covered information. The hidden message can be text, image, speech or even video and accordingly the cover can be chosen from either an image or a video. Here in this paper, the hidden message is text and it is implemented over video file. The traditional well known method uses image as cover which has the limitation of embedding dimension. So, cover should be a video to overcome the limitation of embedding dimension. Nowadays, the use of a video based steganography is common and numbers of steganalysis tools are available to check whether the video is stego-video or not. Most of the tools are checking for information hided by LSB, DCT, Frequency Domain Analysis etc and finds whether the video has hidden or secret data or not. In this paper, LSB and Random Byte Hiding techniques are implemented and MATLAB based implementation is done to simulate the results.
